<abstract>
<p>Conceptualized within the framework of self-determination theory, the aim of the current study was to investigate the relation between perfectionistic concerns and (a) controlled (non-self-determined) motivation and (b) performance anxiety through basic psychological need frustration (frustration of competence, autonomy, and realtedness), and if these relations would be moderated by controlling teaching/coaching conditions. We used a cross-sectional moderated mediation design and purposefully selected Norwegian elite junior performers (<italic>N</italic> = 171; mean age = 17.3; SD age = 0.94) from talent development schools, who completed an online questionnaire to report their perceptions of the study variables. Associations were examined using structural equation modeling. The results showed that perfectionistic concerns were positively associated with controlling conditions, basic needs frustration, controlled motivation, and performance anxiety. Reported controlling teaching/coaching conditions moderated the positive indirect relationship between perfectionistic concerns and (a) controlled motivation and (b) performance anxiety through competence need frustration. Specifically, these indirect associations were evident for performers reporting moderate or high levels of controlling teaching/coaching conditions. In contrast, there were no indirect associations via competence need frustration for those performers who reported low levels of controlling conditions. In conclusion, the results indicate that perfectionistic concerns appear to be a vulnerability factor that exposes elite junior performers to higher risks of entering a debilitative motivational process. This seems especially likely when exposed to controlling teaching/coaching conditions. Coaches and teachers working with elite junior performers should avoid using controlling mechanisms and instead foster autonomous functioning.</p>

<sec><title>Introduction</title>
<p>Elite junior performers in sport and performing art are at increased risk for poor functioning and ill-being compared to the average population, due to the unique requirements associated with reaching excellence (<xref ref-type="bibr" rid="B32">Hill A. et al., 2016</xref>; <xref ref-type="bibr" rid="B44">Mainwaring and Finney, 2017</xref>; <xref ref-type="bibr" rid="B13">Drew et al., 2018</xref>). This urges scholars to address risk factors (e.g., traits and conditions) to better safeguard talent development environments (TDEs). Perfectionism is such a trait risk factor found to be more common in elite performers (<xref ref-type="bibr" rid="B14">Dunn et al., 2012</xref>). Particularly, perfectionistic concerns (PC) are considered a vulnerability factor associated with higher levels of controlled motivation (i.e., extrinsically regulated behavior) and performance anxiety (<xref ref-type="bibr" rid="B67">Stoeber et al., 2007</xref>; <xref ref-type="bibr" rid="B33">Hill A.P. et al., 2016</xref>; <xref ref-type="bibr" rid="B54">Patston and Osborne, 2016</xref>). To understand why and under what circumstances elite junior performers reporting PC are at risk of experiencing controlled motivation and performance anxiety, we applied the conceptual framework of self-determination theory (SDT; <xref ref-type="bibr" rid="B57">Ryan and Deci, 2017</xref>). Specifically, we wanted to examine the potential roles of controlling teaching/coaching conditions and basic psychological need frustration (i.e., need for competence, autonomy, and relatedness) as explaining mechanisms.</p>
<p>Perfectionism is a trait defined as the desire to reach very high standards accompanied by overly self-critical evaluations (<xref ref-type="bibr" rid="B22">Frost et al., 1990</xref>; <xref ref-type="bibr" rid="B34">Hill, 2016</xref>). Perfectionistic concerns (PC), a sub-dimension of perfectionism, are characterized by combinations of concern over mistakes, doubts about actions, and fear of negative social evaluation, regardless of achievements (<xref ref-type="bibr" rid="B34">Hill, 2016</xref>). Paradoxically, PC energize a strong motivational force to strive (i.e., focus, persistence, and discipline), yet, the rigid over-striving attitude, directed toward seeking approval, avoiding mistakes, and maintaining self-worth, also facilitates debilitative patterns of cognition, affect, and behavior (<xref ref-type="bibr" rid="B12">DiBartolo et al., 2004</xref>; <xref ref-type="bibr" rid="B1">Appleton and Curran, 2016</xref>; <xref ref-type="bibr" rid="B54">Patston and Osborne, 2016</xref>). Indeed, research evidence concerning PC shows consistent positive associations with a range of maladaptive outcomes, such as controlled motivation, performance anxiety, and achievement challenges (<xref ref-type="bibr" rid="B23">Gotwals et al., 2012</xref>; <xref ref-type="bibr" rid="B33">Hill A.P. et al., 2016</xref>).</p>
<p>Performance anxiety is defined as experienced stress before and during performance, often because of an apparent imbalance between situational demands and the perceived competence to counter the requests (<xref ref-type="bibr" rid="B40">Lazarus, 2000</xref>; <xref ref-type="bibr" rid="B9">Correia and Rosado, 2018</xref>). Performance anxiety comprises cognitive anxiety (i.e., negative self-talk, catastrophizing), somatic anxiety (i.e., increased heart rate, muscle tension), and self-confidence (i.e., doubts in one&#x2019;s abilities; <xref ref-type="bibr" rid="B10">Cox and Russell, 1999</xref>). TDEs are likely to be stressful (e.g., high expectations, social evaluation, and deselection), generally nurturing performance anxiety in both elite and elite junior performers (<xref ref-type="bibr" rid="B54">Patston and Osborne, 2016</xref>). Furthermore, there is support for a positive relation between PC and performance anxiety, and high levels of PC have been associated with higher risk of developing performance anxiety (<xref ref-type="bibr" rid="B54">Patston and Osborne, 2016</xref>). When displaying high levels of PC, the tendency to feel inadequate and self-critical constantly threatens the balance between demands and perceived competence. Moreover, PC seem to affect the cognitive dimension of anxiety most strongly (<xref ref-type="bibr" rid="B48">Miller and Chesky, 2004</xref>; <xref ref-type="bibr" rid="B70">Walker and Nordin-Bates, 2010</xref>). The accompanying doubt, worry, and negative self-talk that follows PC when facing risk of failure, have been found to activate stress and avoidance coping strategies (<xref ref-type="bibr" rid="B40">Lazarus, 2000</xref>; <xref ref-type="bibr" rid="B33">Hill A.P. et al., 2016</xref>). Hence, performers with PC seem to lack growth-seeking and proactive behavior when confronted with stress, thereby being even more vulnerable when participating in TDEs (<xref ref-type="bibr" rid="B66">Stoeber and Eismann, 2007</xref>; <xref ref-type="bibr" rid="B33">Hill A.P. et al., 2016</xref>).</p>
<p>Although the relationship between PC and performance anxiety is well documented, the explanatory mechanisms involved have been understudied (<xref ref-type="bibr" rid="B5">Boone et al., 2014</xref>). Given that PC is considered a general vulnerability factor for a broad range of maladaptive outcomes (e.g., controlled motivation, performance anxiety, and burnout: <xref ref-type="bibr" rid="B33">Hill A.P. et al., 2016</xref>), focusing on more broad dynamics involved in PC might help extend the perfectionism literature. Hence, this study is building on previous studies applying the general theoretical framework of SDT (<xref ref-type="bibr" rid="B5">Boone et al., 2014</xref>; <xref ref-type="bibr" rid="B35">Jowett et al., 2016</xref>) and testing some core motivational concepts (controlling conditions and basic psychological needs) as explanations of <italic>why</italic> and <italic>when</italic> debilitative processes occur (<xref ref-type="bibr" rid="B69">Vansteenkiste and Ryan, 2013</xref>; <xref ref-type="bibr" rid="B57">Ryan and Deci, 2017</xref>).</p>
<p>A central tenet of SDT is that the satisfaction of the three basic psychological needs, nurtures psychological growth and well-being (<xref ref-type="bibr" rid="B57">Ryan and Deci, 2017</xref>). Conversely, need frustration underpins a range of malfunctioning and ill-being constructs (<xref ref-type="bibr" rid="B69">Vansteenkiste and Ryan, 2013</xref>; <xref ref-type="bibr" rid="B24">Haerens et al., 2015</xref>; <xref ref-type="bibr" rid="B57">Ryan and Deci, 2017</xref>). These needs are competence (feeling mastery when interacting with one&#x2019;s environment), autonomy (experiencing volition, and acting in accordance with one&#x2019;s true self), and relatedness (experiencing a mutual connectedness with others; <xref ref-type="bibr" rid="B69">Vansteenkiste and Ryan, 2013</xref>). When experiencing need frustration, the needs would manifest in feelings of inferiority and failure (competence need frustration), pressure and manipulation (autonomy need frustration), and distance and isolation (relatedness need frustration; <xref ref-type="bibr" rid="B24">Haerens et al., 2015</xref>).</p>
<p>A recent meta-analysis found that PC were consistently associated with need frustration (<xref ref-type="bibr" rid="B31">Hill and Curran, 2016</xref>). Given the ultimate goal of demonstrating outstanding performance, and the competitive nature of TDEs, failure seems at least as likely an outcome as success for elite junior performers. Hence, the need for competence seems to be especially at risk of not being satisfied in TDEs. When displaying PC, one&#x2019;s competence evaluation is often biased (<xref ref-type="bibr" rid="B61">Shafran et al., 2002</xref>); self-critical and harsh when faced with failure, and underestimated and re-evaluated when faced with success. In addition, PC are associated with a lack of reactivity patterns to cope with adversity (<xref ref-type="bibr" rid="B18">Flett and Hewitt, 2016</xref>). Hence, frustration of competence might be the outcome, independently of any objectively achieved results. PC are also associated with rigid and controlled behavior regulations (i.e., &#x201C;must,&#x201D; &#x201C;have to,&#x201D; and &#x201C;should&#x201D;), which might be out of line with autonomous and creative functioning (<xref ref-type="bibr" rid="B25">Hall, 2016</xref>; <xref ref-type="bibr" rid="B34">Hill, 2016</xref>). Lastly, PC are associated with obsessiveness, social comparisons, and interpersonal inflexibility (indicative of frustration of the need for relatedness), underpinned by a narrow-minded and competitive dedication (<xref ref-type="bibr" rid="B5">Boone et al., 2014</xref>; <xref ref-type="bibr" rid="B25">Hall, 2016</xref>). As such, frustration of the three basic psychological needs seems likely to be nurtured by PC.</p>
<p>The negative consequences of long-term need frustration are evident in prior SDT-based studies, associated with low quality of motivation (e.g., controlled motivation) and various forms of malfunction and ill-being (<xref ref-type="bibr" rid="B69">Vansteenkiste and Ryan, 2013</xref>; <xref ref-type="bibr" rid="B24">Haerens et al., 2015</xref>; <xref ref-type="bibr" rid="B4">Bartholomew et al., 2018</xref>). For example, in a study focusing on resilience processes after experienced need frustration, restoration was nurtured by autonomous functioning and moderated by perceived competence (<xref ref-type="bibr" rid="B55">Radel et al., 2013</xref>). In light of the characteristics of PC, a proactive ability to engage in resilience processes and restore the basic needs when frustrated seems to be lacking when experiencing high levels of PC (<xref ref-type="bibr" rid="B69">Vansteenkiste and Ryan, 2013</xref>; <xref ref-type="bibr" rid="B33">Hill A.P. et al., 2016</xref>).</p>
<p>To date, some evidence of positive associations between PC and need frustration has been found (<xref ref-type="bibr" rid="B33">Hill A.P. et al., 2016</xref>). Recent studies have shown that PC, through general need frustration, were indirectly linked to symptoms of burnout (<xref ref-type="bibr" rid="B35">Jowett et al., 2016</xref>) and binge eating (<xref ref-type="bibr" rid="B5">Boone et al., 2014</xref>). Despite studies having successfully examined relations between the need for competence and motivation, performance, and well-being (<xref ref-type="bibr" rid="B19">Fransen et al., 2018a</xref>,<xref ref-type="bibr" rid="B20">b</xref>), no studies, to our knowledge, have focused on the indirect links between PC and such outcomes through each need separately. In addition, no study has tested whether such indirect associations are conditional on specific environmental aspects, such as controlling teaching/coaching style.</p>
<p>An important area of inquiry, suggested to extend perfectionism research (<xref ref-type="bibr" rid="B1">Appleton and Curran, 2016</xref>), is factors that contribute to explain the development of perfectionism (e.g., the social environment). The pressure of being perfect is proposed to originate from exposure to psychological control (e.g., manipulation through expectations, criticism, and conditional love) imposed by social agents, such as parents (<xref ref-type="bibr" rid="B63">Soenens and Vansteenkiste, 2010</xref>). Thus, perfectionistic behaviors seem to compensate for internal feelings of inadequacy, inferiority, and low self-worth by seeking external approval and acceptance (<xref ref-type="bibr" rid="B17">Eusanio et al., 2014</xref>; <xref ref-type="bibr" rid="B18">Flett and Hewitt, 2016</xref>). The same contingent mechanisms and patterns underlying the child-parent relationship, might be extended and re-visited in adolescence in interpersonal relationships developing in TDEs, such as those with teachers and coaches (<xref ref-type="bibr" rid="B63">Soenens and Vansteenkiste, 2010</xref>). Research from sport psychology has found that social agents using psychological control seem particularly important in the development of the PC aspects of perfectionism that are linked to conditional and unstable self-worth (i.e., fear of negative social evaluation and concern of mistakes; <xref ref-type="bibr" rid="B1">Appleton and Curran, 2016</xref>; <xref ref-type="bibr" rid="B34">Hill, 2016</xref>).</p>
<p>In the SDT-based literature, controlling teaching/coaching style is characterized by the use of conditional regard, meaning that approval and acceptance are given only when students behave or live up to the expected and preconceived standards of emotions, cognitions, and behavior (<xref ref-type="bibr" rid="B56">Reeve, 2009</xref>; <xref ref-type="bibr" rid="B3">Assor et al., 2014</xref>; <xref ref-type="bibr" rid="B4">Bartholomew et al., 2018</xref>). Such controlling teaching/coaching may be represented by humiliation, yelling, critique, or punishment, which have been found to nurture external motivational regulations (<xref ref-type="bibr" rid="B63">Soenens and Vansteenkiste, 2010</xref>; <xref ref-type="bibr" rid="B11">De Meyer et al., 2016</xref>). The experience of pressure and control might also work indirectly via attention withdrawal or showing disappointment, which in turn, may create guilt, shame, self-criticism, and anxiety (<xref ref-type="bibr" rid="B63">Soenens and Vansteenkiste, 2010</xref>; <xref ref-type="bibr" rid="B4">Bartholomew et al., 2018</xref>). These experiences are likely to generate introjected motivational regulations that control the way of thinking and acting from inside the person (<xref ref-type="bibr" rid="B63">Soenens and Vansteenkiste, 2010</xref>). It is worth noting that both introjected and external motivational regulations are characterized as controlled motivation within the SDT-based literature. They are associated with less engagement and persistence, and with the lack of proactive coping strategies (<xref ref-type="bibr" rid="B49">Mouratidis and Michou, 2011</xref>; <xref ref-type="bibr" rid="B57">Ryan and Deci, 2017</xref>). Hence, controlled motivation is likely to be negative for elite performance (<xref ref-type="bibr" rid="B62">Soenens et al., 2012</xref>). PC performers are likely to experience the teaching/coaching style with a biased mindset (<xref ref-type="bibr" rid="B61">Shafran et al., 2002</xref>; <xref ref-type="bibr" rid="B53">Nordin-Bates et al., 2014</xref>), monitoring for critical feedback, lack of attention, and other signs of imperfection or disapproval. Hence, performers reporting higher levels of PC might be more susceptible to the development of controlled motivation and associated outcomes (e.g., performance anxiety) in highly controlling teaching/coaching conditions (<xref ref-type="bibr" rid="B24">Haerens et al., 2015</xref>; <xref ref-type="bibr" rid="B1">Appleton and Curran, 2016</xref>).</p>
<p>Despite the empirical evidence in relation to controlling teaching/coaching behaviors, such a teaching/coaching style still appears to be a common phenomenon in TDEs (<xref ref-type="bibr" rid="B56">Reeve, 2009</xref>; <xref ref-type="bibr" rid="B11">De Meyer et al., 2016</xref>; <xref ref-type="bibr" rid="B4">Bartholomew et al., 2018</xref>). Research has also indicated that controlling conditions are likely to be found within experience-based and top-down apprenticeship cultures (e.g., arts and sports), in which the teachers/coaches are seen as authority figures (i.e., former top performers) and, in some cases, gatekeepers who are holding significant power over their students/athletes (<xref ref-type="bibr" rid="B38">Lakes, 2005</xref>; <xref ref-type="bibr" rid="B51">Nash and Collins, 2006</xref>; <xref ref-type="bibr" rid="B6">Burwell, 2013</xref>). Few studies, however, have investigated the role of controlling conditions within TDE&#x2019;s including elite junior performers of these performance domains.</p>
<p>Based on the research reviewed and SDT-based tenets, the present study tested the following hypotheses (see also <xref ref-type="fig" rid="F1">Figure 1</xref>):</p>

<title>Materials and Methods</title>
<sec><title>Participants and Ethical Considerations</title>
<p>We purposefully recruited and invited all high-achieving elite junior performers (achieving within top 20%) who also attended prestigious junior TDE schools across selected activities in sport and arts in Norway at age 16&#x2013;19 (<italic>M</italic> = 17.31; <italic>SD</italic> = 0.94). The 171 participants (84 boys, 87 girls) came from individual sports (<italic>N</italic> = 118; swimming, rowing, athletics, skating, cross-country skiing, biathlon, and alpine skiing) and art (<italic>N</italic> = 59; classical music and ballet). The TDEs in sport were operated by the sports federations in collaboration with the Norwegian Olympic Center and specialized private high schools for elite sports, while specialized higher education institutions ran the TDE schools (conservatoires) within the arts. All programs had entrance regulated by competitive auditions, and offered both acceleration and enrichment. The study gained a response rate of 84%, and thus, represent a unique sample of the best junior performers present in the small country of Norway (about 5 million inhabitants). Other studies of successful versus less successful elite performers across domains have found that elite performers are distinctive, sharing many similar psychological characteristics (<xref ref-type="bibr" rid="B16">Ericsson et al., 2003</xref>). The performers had all participated in deliberate practice in their activity for many years (<italic>M</italic> = 9.56; <italic>SD</italic> = 3.21). Moreover, they spent many hours on their activity each week (<italic>M</italic> = 20.92; <italic>SD</italic> = 7.98).</p>
<p>We recruited the participants through a dialogue with sport federations, national teams, and leaders of TDE schools. They voluntarily and in writing consented to participate in accordance to the Declaration of Helsinki, after receiving oral and/or written information about the study. This study was carried out after ethical approval of the protocol by the state governed Norwegian Center for Research Data (approval code nr. 53471). The data was collected using a digital survey tool called SurveyXACT, and the participants received a personal link by email. In collaboration with the sport federations and TDE art schools, the first author traveled to collect the data directly in separate activity groups, which helped monitor the data collection settings. For some participants, however, the survey was answered privately due to a lack of scheduled national team practices or due to absence. Finally, the data was transferred to IBM Statistics SPSS 24.0 and M<italic>plus</italic> version 8 for data analyses.</p>
</sec>
<sec><title>Measurements</title>
<p>All measurements are based on translated, contextualized, piloted, and validated questionnaires. To contextualize the measurements the first author translated the questionnaires to Norwegian, the fourth author performed a back-translation and both adjusted the final version. The contextualization was executed by instructional information, &#x201C;tagging&#x201D; in front of each item section, as well as contextualized adaptation on item-level where it was natural to do so (<xref ref-type="bibr" rid="B43">Madigan and Stoeber, 2016</xref>). We then tested a pilot version of the questionnaire on two former TDE performers who gave feedback on the given use of language, contextualization, and instructions, before administering the survey.</p>
<sec><title>Perfectionistic Concerns</title>
<p>A contextualized version of the Frost Multidimensional Perfectionism Scale was used (F-MPS; <xref ref-type="bibr" rid="B22">Frost et al., 1990</xref>). The subscales Concern over Mistakes (CM, nine items; e.g., &#x201C;If I fail at my activity, I feel like a failure as a person&#x201D;) and Doubts about Actions (DA &#x2013; four items; e.g., &#x201C;It takes me a long time to do something &#x201C;right&#x201D;) assessed perfectionistic concerns. The participants answered on a 7-point Likert scale from 1 (<italic>totally disagree</italic>) to 7 (<italic>totally agree</italic>). This scale has been shown reliable and valid in several studies, including in contextualized versions in sport and art (<xref ref-type="bibr" rid="B43">Madigan and Stoeber, 2016</xref>).</p>

<sec><title>Controlling Conditions</title>
<p>The Perceived Controlling Style Scale (<xref ref-type="bibr" rid="B26">Halvari et al., 2012</xref>), was used (six items; e.g., &#x201C;I experience that my teacher/coach is making all the decisions&#x201D;). Responses were made on a 5-point Likert scale from 1 (<italic>totally disagree</italic>) to 5 (<italic>totally agree</italic>). The initial validation study supported the internal consistency and factor structure of the scale (<xref ref-type="bibr" rid="B26">Halvari et al., 2012</xref>).</p>
</sec>
<sec><title>Need Frustration</title>
<p>The Basic Psychological Need Satisfaction and Frustration Scale (<xref ref-type="bibr" rid="B7">Chen et al., 2015</xref>) was adapted to measure need frustration. Four items captured need frustration for each of competence (e.g., &#x201C;I feel insecure regarding my ability to master my activity&#x201D;), autonomy (e.g., &#x201C;Most of the things I do feel like &#x201C;I have to&#x201D;), and relatedness (e.g., &#x201C;I feel the relationships I have are just superficial&#x201D;). The subscales were measured on a 7-point Likert scale from 1 (<italic>totally disagree</italic>) to 7 (<italic>totally agree</italic>). This scale has been validated and assessed across contexts and cultures (<xref ref-type="bibr" rid="B7">Chen et al., 2015</xref>).</p>
</sec>
<sec><title>Controlled Motivation</title>
<p>The Behavioral Regulations in Sport Questionnaire (BRSQ; <xref ref-type="bibr" rid="B41">Lonsdale et al., 2008</xref>) subscales of introjected regulation (four items; e.g., &#x201C;I would feel ashamed if I quit&#x201D;) and external regulation (e.g., &#x201C;I feel pressure from other people to participate in my activity&#x201D;) was used. The responses were made on a 7-point Likert scale from 1 (<italic>totally disagree</italic>) to 7 (<italic>totally agree</italic>). The instrument has been developed and shown to be valid in sport contexts, as well as in art contexts (<xref ref-type="bibr" rid="B27">Hancox et al., 2015</xref>).</p>
</sec>
<sec><title>Performance Anxiety</title>
<p>The Mental Readiness Form (MRF-3; e.g., <xref ref-type="bibr" rid="B37">Krane, 1994</xref>) assessed performance anxiety related to competitive situations (i.e., competition or stage performance). This is a short form of only three items, designed and validated (<xref ref-type="bibr" rid="B10">Cox and Russell, 1999</xref>) to correspond with subscales of cognitive anxiety, somatic anxiety, and self-confidence from the Competitive State Anxiety Inventory (<xref ref-type="bibr" rid="B47">Martens et al., 1990</xref>). Responses were made on a scale ranging from 1 to 100% of anxiety arousal (divided by 10 in the analyses) to assess the participants&#x2018; experienced anxiety levels.</p>
</sec>
</sec>
<sec><title>Analytical Strategy</title>
<p>The data were first checked for normality, missing values, and outliers (<xref ref-type="bibr" rid="B68">Tabachnick and Fidell, 2007</xref>). To validate the measures we tested factor loadings and model fit using confirmatory factor analyses (CFA) in M<italic>plus</italic> version 8. If the validation failed, we did supplemental explorative factor analysis (EFA) in SPSS to explore how data adjusted to the expected theoretical subscales in our sample and searched for reduced, but theoretical meaningful subscales. Finally, we calculated reliability values for each scale in M<italic>plus</italic> using coefficient omega, found more appropriate for most research applications (<xref ref-type="bibr" rid="B71">Widaman et al., 2011</xref>).</p>
<p>Next, we calculated descriptive statistics and bivariate correlations using SPSS. The Spearman &#x03C1; was applied, as dichotomous controlling variables (gender, domain) were included, and as it has been found more robust to a lack of normal distribution (<xref ref-type="bibr" rid="B68">Tabachnick and Fidell, 2007</xref>). Cohen&#x2019;s evaluation of small (<italic>r</italic> = 0.10&#x2013;0.29), medium (<italic>r</italic> = 0.30&#x2013;0.49), and large effects (<italic>r</italic> > 0.50) were used for interpretation (<xref ref-type="bibr" rid="B8">Cohen et al., 2003</xref>).</p>
<p>For the main analyses, we applied moderated mediation (<xref ref-type="bibr" rid="B29">Hayes, 2017</xref>; <xref ref-type="bibr" rid="B50">Muth&#x00E9;n et al., 2017</xref>). To extend the popular mediation models scholars have suggested that it may be wise to determine if an association is constant across different contexts, groups or characteristics of individuals, or contingent of the interaction with circumstances (<xref ref-type="bibr" rid="B29">Hayes, 2017</xref>). We therefore first conducted simple moderation analysis in SPSS using <xref ref-type="bibr" rid="B29">Hayes (2017)</xref> model templates with mean-centered product variables. This analysis explored the contribution of the direct and interaction associations of PC and controlling conditions on the intervening variables (each need frustration), and to receive beta coefficients to probe and visualize the interactions. This procedure was repeated in three models for each need separately.</p>
<p>Structural Equation Modeling (SEM) was chosen for the final analyses of the full models as it also provides model fit indices, bootstrap confidence intervals (CI), and strategies for dealing with missing data. For reasons of parsimony and to increase statistical power, we estimated the model containing only one intervening variable and one outcome variable at a time. Aligned with critique raised toward estimation of interaction of latent variables (<xref ref-type="bibr" rid="B29">Hayes, 2017</xref>), and as the sample size of the current study may be regarded as low for latent variables modeling (<italic>N</italic> = 171), manifested variables were used in the SEM models to ensure sufficient statistical power (<xref ref-type="bibr" rid="B8">Cohen et al., 2003</xref>; <xref ref-type="bibr" rid="B60">Schweizer and Furley, 2016</xref>). An <italic>a priori</italic> sample size calculator for multiple regression (<xref ref-type="bibr" rid="B64">Soper, 2018</xref>) recommended minimum 97 participants to reach a power level of 0.8 to detect an effect size of 0.15, at an alpha level of 0.05 and with six variables. As suggested by previous research (e.g., <xref ref-type="bibr" rid="B46">Marsh et al., 2004</xref>), good model fit is indicated by a chi-square non-significant <italic>p</italic>-value (>0.05). As the chi-square test can be sensitive to sample size, however, the relative chi-square (&#x03C7;<sup>2</sup>/df &#x003C;2) is a robust supplemental test (<xref ref-type="bibr" rid="B46">Marsh et al., 2004</xref>). For additional fit evaluation, we relied on both incremental (CFI) and absolute (RMSEA/SRMR) indices. Fit was deemed acceptable if RMSEA/SRMR values were close to or lower than 0.08, accompanied by a CFI value close to or higher than 0.95 (<xref ref-type="bibr" rid="B46">Marsh et al., 2004</xref>).</p>

<p>There were no outliers and few missing data (0.6&#x2013;1.7%). The missing data were handled using Full Information Maximum Likelihood, claimed to be a robust strategy (<xref ref-type="bibr" rid="B39">Lang and Little, 2018</xref>). As the variables were moderately skewed (range -0.04 to 1.09) and kurtosis (range -0.04 to 1.16; e.g., <xref ref-type="bibr" rid="B68">Tabachnick and Fidell, 2007</xref>), as expected in a high-achieving sample, 10.000 bootstrap was conducted in all analysis as advised by previous researchers (<xref ref-type="bibr" rid="B52">Ng and Lin, 2016</xref>).</p>
<p>An overall CFA of all the study variables showed acceptable fit [&#x03C7;<sup>2</sup>(565) = 860.13, <italic>p</italic> = 0.00, &#x03C7;<sup>2</sup>/df = 1.5, CFI = 0.90, SRMR = 0.06, RMSEA = 0.06 (90% CI, 0.05&#x2013;0.06)] after some adjustments in the validation process of each sub-scale. Especially the concern over mistakes sub-scale of PC had to be reduced and adjusted (for details of the instrument validation, see <xref ref-type="supplementary-material" rid="SM1">Supplementary Material</xref>).</p>

<sec><title>Descriptive Statistics and Bivariate Correlations</title>
<p><xref ref-type="table" rid="T1">Table 1</xref> presents means, standard deviations, reliability estimates, and inter-correlations for all study variables, including domain and gender. As shown, the performers tended to display moderate levels of PC, low levels of controlling conditions, basic needs frustration, controlled motivation, and moderate levels of performance anxiety. In line with hypothesis 1, the correlations revealed that PC shared medium to large positive associations with all other variables.</p>

Sport performers scored lower on these variables compared to art performers. Due to these results, and to keep the main model as parsimonious as possible, domain was added as a categorical control variable associated with the intervening variables (need frustration), whereas domain and gender were added as categorical control variables associated to the outcomes (introjected, external, and anxiety) to control for their influence on the model results.</p>

<sec><title>Main Analyses</title>
<sec><title>Moderation</title>
<p>Hypothesis 2 suggested that controlling conditions would moderate positively the relation between PC and each need frustration, such that this association would be stronger for those who reported higher, instead of lower, levels of controlling conditions. However, the analyses using PC as an independent variable and controlling conditions as a moderator toward each need as dependent variables, showed only support for the moderation model on need for competence (PC/b<sub>1</sub>x = 0.53, <italic>p</italic> = 0.00; Control/b<sub>2</sub>w = 0.55, <italic>p</italic> = 0.00; PC<sup>&#x2217;</sup>control/b<sub>3</sub>xw = 0.29, <italic>p</italic> = 0.01; <italic>R</italic><sup>2</sup> = 0.45). In the cases of frustration of need for autonomy (PC/b<sub>1</sub>x = 0.38, <italic>p</italic> = 0.00; Control/b<sub>2</sub>w = 0.59, <italic>p</italic> = 0.00, PC<sup>&#x2217;</sup>control/b<sub>3</sub>xw = 0.13, <italic>p</italic> = 0.30; <italic>R</italic><sup>2</sup> = 0.27) and relatedness (PC/b<sub>1</sub>x = 0.32 <italic>p</italic> = 0.00; Control/b<sub>2</sub>w = 0.52, <italic>p</italic> = 0.00; PC<sup>&#x2217;</sup>control/b<sub>3</sub>xw = 0.16, <italic>p</italic> = 0.158; <italic>R</italic><sup>2</sup> = 0.28), no significant interactions were present. In summary, these moderation analyses showed that hypothesis 2 was supported only in the model of frustration of competence. Specifically, as visualized in <xref ref-type="fig" rid="F2">Figure 2</xref>, competence frustration was stronger for those experiencing higher levels of controlling conditions, and this difference increased when PC increased (calculated from equation: &#x1EF9; = &#x00EC;y +b1x +b2w&#x2019; +b3xw&#x2019;, with -1 SD below the mean as low, and 1 SD above the mean as high values; <xref ref-type="bibr" rid="B29">Hayes, 2017</xref>). The additional <italic>t</italic>-tests with the Johnson-Neyman technique (<xref ref-type="bibr" rid="B29">Hayes, 2017</xref>) for the model of competence frustration showed that the range of statistical significance covered the entire variety of the moderator values in the data from the lowest score 1 (<italic>t</italic> = 2.43, <italic>p</italic> = 0.02) to the highest score 4.2 (<italic>t</italic> = 4.22, <italic>p</italic> = 0.00). Due to these results, the competence need frustration (CNF) was decided to be the only intervening variable used while testing hypothesis 3 in the further moderated mediation analyses.</p>

<sec><title>Moderated Mediation</title>
<p>Complete moderated mediation results are presented in <xref ref-type="table" rid="T2">Table 2</xref>. The models provided very good fit indices for the models of introjected motivation<sup>a</sup>, &#x03C7;<sup>2</sup>(1) = 0.10, <italic>p</italic> = 0.76, &#x03C7;<sup>2</sup>/df = 0.05, CFI = 1.00, SRMR = 0.03, RMSEA = 0.00 (90% CI, 0.00&#x2013;0.14), external motivation<sup>b</sup>, &#x03C7;<sup>2</sup>(1) = 0.10, <italic>p</italic> = 0.74, &#x03C7;<sup>2</sup>/df = 0.05, CFI = 1.00, SRMR = 0.03, RMSEA = 0.00 (90% CI, 0.00&#x2013;0.14), and performance anxiety<sup>c</sup>, &#x03C7;<sup>2</sup>(1) = 0.88, <italic>p</italic> = 0.77, &#x03C7;<sup>2</sup>/df = 0.19, CFI = 1.00, SRMR = 0.03, RMSEA = 0.00 (90% CI, 0.00&#x2013;0.14). The effect sizes of explained variance of the intervening variable CNF (<italic>R</italic><sup>2</sup> = 0.45), as well as for the outcomes (a) introjected motivation (<italic>R</italic><sup>2</sup> = 0.32), (b) external motivation (<italic>R</italic><sup>2</sup> = 0.29), and (c) performance anxiety (<italic>R</italic><sup>2</sup> = 0.32) were large (<xref ref-type="bibr" rid="B21">Fritz et al., 2012</xref>). The results showed direct associations from PC on introjected motivation (&#x03B2; = 0.18, <italic>p</italic> = 0.02) and performance anxiety (&#x03B2; = 0.20, <italic>p</italic> = 0.03), but not on external motivation (&#x03B2; = 0.00, <italic>p</italic> = 0.96). In contrast, direct associations were found from controlling conditions on external motivation (&#x03B2; = 0.23, <italic>p</italic> = 0.003), but not on introjected motivation (&#x03B2; = 0.11, <italic>p</italic> = 0.158) and performance anxiety (&#x03B2; = 0.04, <italic>p</italic> = 0.654). There was no significant direct interaction effects (PC<sup>&#x2217;</sup>Controlling conditions) associated with the three outcomes in any of the models. However, the index of the conditional indirect effects between PC and (a) introjected motivation [<italic>index</italic> = 0.29 (95% CI, 0.10&#x2013;0.57), <italic>p</italic> = 0.01], external motivation, [<italic>index</italic> = 0.21 (95% CI, 0.07&#x2013;0.43), <italic>p</italic> = 0.02], and (c) performance anxiety [<italic>index</italic> = 0.26 (95% CI, 0.08&#x2013;0.56), <italic>p</italic> = 0.03], via CNF, was significant. These results support hypothesis 3, as the relation between PC and the outcomes was more evident as the moderator values increased, showed by conditional indirect effects that was significant at mean and high levels (+1 SD) of the moderator, but not at the low level (-1 SD).</p>

<sec><title>Discussion</title>
<p>The purpose of this study was to examine why and under what circumstances perfectionistic concerns (PC) were associated with controlled motivation and performance anxiety in a sample of elite junior performers. We aimed to test the roles of controlling conditions and need frustration as explanatory mechanisms. In general, the results showed that the typical Norwegian elite junior performer experienced adaptive and well-functioning motivational processes. However, the results supported the vulnerability hypothesis of PC as a variable related to debilitative motivational processes. Furthermore, the current study tested and found support for the role of competence need frustration (CNF) as the key intervening variable between PC and the outcomes of (a) introjected motivation, (b) external motivation, and (c) performance anxiety. In addition, controlling teaching/coaching conditions were a moderator as the debilitative motivational processes tested in the three models were more evident among those reporting higher levels of controlling teaching/coaching conditions. Implications of these findings are discussed below and structured in line with the three hypotheses.</p>
<sec><title>The Debilitative Motivational Signature of PC Among Elite Junior Performers</title>
<p>The linking of the PC trait with SDT tenets both corroborated and extended previous perfectionism research. Supporting hypothesis 1, the results showed that higher levels of PC were positively associated with perceptions of controlling teaching/coaching style, the frustration of basic psychological needs, controlled motivation, and performance anxiety. This confirms initial evidence of PC as a contributor to SDT&#x2019;s maladaptive motivational path, which is characterized by need frustration, controlled motivation, dysfunction, and ill-being (<xref ref-type="bibr" rid="B5">Boone et al., 2014</xref>; <xref ref-type="bibr" rid="B34">Hill, 2016</xref>; <xref ref-type="bibr" rid="B35">Jowett et al., 2016</xref>). These findings may indicate that the motivational signature of PC, particularly within TDEs, is the paradoxical portrayal of &#x201C;successful failures,&#x201D; characterized by conditional self-worth, self-critical attitudes, over-striving, and avoidance coping strategies (<xref ref-type="bibr" rid="B17">Eusanio et al., 2014</xref>; <xref ref-type="bibr" rid="B25">Hall, 2016</xref>; <xref ref-type="bibr" rid="B54">Patston and Osborne, 2016</xref>). That is, even elite junior performers, such as those sampled for this study, may end up feeling imperfect and as &#x201C;failures&#x201D; if they also possess high levels of PC, regardless of their quite extraordinary achievements (top 20% in their national age group). Linked with controlled motivation, and performance anxiety, such a motivational process certainly seems at odds with suggested guidelines for healthy TD (<xref ref-type="bibr" rid="B32">Hill A. et al., 2016</xref>).</p>
</sec>
<sec><title>Need Frustration and the Role of Competence Need Frustration</title>
<p>The results partially supported hypothesis 2 and demonstrated that higher levels of PC were associated with introjected motivation and performance anxiety both directly and, more strongly, indirectly through CNF. External motivation had only indirect associations. These findings fit nicely alongside recent work in sport psychology that has clarified basic needs as intervening variables in the relation between perfectionism and burnout (<xref ref-type="bibr" rid="B45">Mallinson and Hill, 2011</xref>; <xref ref-type="bibr" rid="B35">Jowett et al., 2016</xref>). Our findings also extend these studies by testing other outcomes known to undermine optimal functioning and well-being in elite junior performers, such as controlled motivation and performance anxiety (<xref ref-type="bibr" rid="B72">Woodman and Hardy, 2003</xref>; <xref ref-type="bibr" rid="B36">Kenny et al., 2004</xref>; <xref ref-type="bibr" rid="B11">De Meyer et al., 2016</xref>; <xref ref-type="bibr" rid="B9">Correia and Rosado, 2018</xref>).</p>
<p>The results add interesting nuances to previous studies of needs frustration (<xref ref-type="bibr" rid="B45">Mallinson and Hill, 2011</xref>; <xref ref-type="bibr" rid="B5">Boone et al., 2014</xref>; <xref ref-type="bibr" rid="B35">Jowett et al., 2016</xref>), as only the need for competence functioned as an intervening variable between PC on the one hand, and controlled motivation and performance anxiety on the other. There were also positive associations between PC and frustration of the other two needs (i.e., autonomy and relatedness). However, no significant interaction effect, or indirect associations on the outcomes, were found. As such, the need for competence turned out to be the key psychological need in the current sample of elite junior performers. As found in other TDEs studies (e.g., <xref ref-type="bibr" rid="B19">Fransen et al., 2018a</xref>,<xref ref-type="bibr" rid="B20">b</xref>; <xref ref-type="bibr" rid="B65">Stabell, 2018</xref>) competence seems to be the most important &#x201C;currency&#x201D; in TDEs. As the very essence of TDEs is to demonstrate superiority and outperform others, further possibilities (i.e., social status, attention, re-selection, and advantages) are seemingly dependent on achieved success (<xref ref-type="bibr" rid="B65">Stabell, 2018</xref>). Hence, elite junior performers reporting higher levels of PC are likely to get their inherited vulnerability and conditional self-worth activated when operating within TDEs (<xref ref-type="bibr" rid="B25">Hall, 2016</xref>). To avoid inferiority and failure, elite junior performers reporting higher levels of PC might end up in a debilitative motivational circle of emotions (i.e., frustration, stress, and negative affect), cognition (i.e., guilt, shame, and fear of failure), and behavior (i.e., rigidity, obsession, and avoidance strategies), constantly nurturing their CNF, controlled motivation, and performance anxiety (<xref ref-type="bibr" rid="B18">Flett and Hewitt, 2016</xref>). Due to the cross-sectional nature of the study, this is initial evidence, and we suggest the need for future studies extending this line of perfectionism research with longitudinal designs.</p>
<p>Concerning explanations of why CNF and not autonomy and relatedness did intervene between PC and the outcomes of controlled motivation and performance anxiety in the current study, one might only speculate. For example, one explanation might be the unique and vital role competence holds, not only as a core driver of PC (<xref ref-type="bibr" rid="B34">Hill, 2016</xref>), but also within the three tested outcomes. Performance anxiety is triggered by an experienced imbalance between situational demands and perceived competence (<xref ref-type="bibr" rid="B9">Correia and Rosado, 2018</xref>). Also in SDT, the origin of positive functioning and autonomous motivation (opposite to controlled motivation) are tied to competence, to the innate urge to interact effectively and master one&#x2019;s surroundings (<xref ref-type="bibr" rid="B15">Elliot et al., 2002</xref>). Moreover, competence is especially activated in TDEs, where competence seems to be the currency that controls the conditional regard inherited in the controlling teaching/coaching style (<xref ref-type="bibr" rid="B65">Stabell, 2018</xref>; <xref ref-type="bibr" rid="B28">Haraldsen et al., in press</xref>), resulting in a strong conceptual coherence between the study variables in the model where CNF are used as the explanatory mechanism. More research is needed to extend this line of SDT-based research in diverse contexts.</p>
</sec>
<sec><title>The Moderating Role of Controlling Conditions</title>
<p>The interaction between PC and controlling teaching/coaching conditions has been less studied compared to PC and parenting styles (<xref ref-type="bibr" rid="B62">Soenens et al., 2012</xref>; <xref ref-type="bibr" rid="B3">Assor et al., 2014</xref>). Hence, the current study tested whether tendencies typically associated with parenting style (an origin of PC), could be extended to the teaching/coaching setting in TDEs. The results indicated that this was the case, as the interaction between PC and controlling teaching/coaching conditions (<xref ref-type="bibr" rid="B4">Bartholomew et al., 2018</xref>), were associated with higher levels of CNF, controlled motivation, and performance anxiety.</p>
<p>When reporting high levels of PC, elite junior performers might be biased in the way they perceive their teaching/coaching styles (<xref ref-type="bibr" rid="B2">Appleton et al., 2011</xref>; <xref ref-type="bibr" rid="B5">Boone et al., 2014</xref>; <xref ref-type="bibr" rid="B53">Nordin-Bates et al., 2014</xref>). Activated by aspects of controlling conditions, they are likely to enter a kind of hypervigilant state, driven by emotional stress from their conditional self-worth, which in turn, seems to associate with fear of failure and avoidance motivation (<xref ref-type="bibr" rid="B61">Shafran et al., 2002</xref>). Controlling conditions might reinforce this pattern, as a trigger and extension of conditional regard received from another significant other (<xref ref-type="bibr" rid="B3">Assor et al., 2014</xref>). The displaying of higher levels of PC might also function as a substitute for being externally controlled, as a way of taking the control back, directing it into self-control, obsessiveness, and relentless pursuit for success (<xref ref-type="bibr" rid="B61">Shafran et al., 2002</xref>; <xref ref-type="bibr" rid="B5">Boone et al., 2014</xref>). Thus, such behavior might trigger and increase the PC tendencies within performers, whereas, when faced with low controlling conditions these tendencies might be immobilized (<xref ref-type="bibr" rid="B61">Shafran et al., 2002</xref>; <xref ref-type="bibr" rid="B53">Nordin-Bates et al., 2014</xref>).</p>
<p>From an applied perspective, the most vital lesson learned from this study might be the importance of avoiding controlling mechanisms. This seems especially true in ambitious performance-oriented TDE settings, where too many performers are likely to experience higher levels of PC, as well as risking failure and adversity (<xref ref-type="bibr" rid="B14">Dunn et al., 2012</xref>; <xref ref-type="bibr" rid="B1">Appleton and Curran, 2016</xref>; <xref ref-type="bibr" rid="B59">Schinke et al., 2017</xref>). Moreover, teachers/coaches should be encouraged to pay attention to how they as authority figures and gatekeepers (<xref ref-type="bibr" rid="B51">Nash and Collins, 2006</xref>; <xref ref-type="bibr" rid="B6">Burwell, 2013</xref>), indirectly (and perhaps unintentionally) hold power, and thus might pressure, control, and affect elite junior performers&#x2019; motivation in conditional and, hence, debilitative directions. As an alternative, and in line with the SDT tenets, they should be stimulated and taught how to behave in less controlling and in more autonomy-supportive ways, as research indicates that autonomous functioning might be a proactive coping strategy and resilience factor (<xref ref-type="bibr" rid="B55">Radel et al., 2013</xref>; <xref ref-type="bibr" rid="B57">Ryan and Deci, 2017</xref>; <xref ref-type="bibr" rid="B58">Ryan and Ryan, 2018</xref>).</p>
</sec>
<sec><title>Strengths, Limitations, and Future Research</title>
<p>The findings should be interpreted in light of some limitations. The cross-sectional design, preventing temporal precedence, hampers absolute evidence of the order of variables or the stability of the indirect associations tested. Another limitation originates from the sole reliance on self-report data, which may be a threat to validity. The sample size (<italic>N</italic> = 171) might be a limitation from a statistical perspective; however, the sample is also a strength, as it accounts for almost all of the unique and exclusive top 20% high-achieving population of elite junior performers in Norway (response rate = 84%). Strengths are also the novel and sophisticated conditional process modeling (for details, see <xref ref-type="bibr" rid="B29">Hayes, 2017</xref>), linking controlling teaching/coaching style with perfectionism, and hence, providing deeper insight into the motivational signature of perfectionism in elite junior performers. Thus, future studies should re-examine similar models longitudinally with larger samples from different domains and TDE settings.</p>

<sec><title>Conclusion</title>
<p>Framed within SDT, the present study examined the motivational signature of PC in a sample of Norwegian elite junior performers from sport and arts. The results indicated that displaying high levels of PC might expose elite junior performers to higher risks of experiencing debilitative motivational processes. Specifically, they appear more likely to develop controlled motivation and experience performance anxiety through competence need frustration (CNF). Furthermore, the findings indicated that these experiences were conditional on varying levels of reported controlling teaching/coaching conditions. Hence, the indirect associations on controlled motivation and performance anxiety via CNF was more evident in performers reporting mean and higher levels of controlling teaching/coaching conditions. In contrast, there were no indirect associations via CNF for those performers who reported low levels of controlling conditions. Overall, these findings support key tenets of SDT and implies that coaches/teachers of elite junior performers might play a key role in preventing CNF and experiences of debilitative motivational processes through avoiding the misuse of a controlling teaching/coaching style.</p>
