The literature was searched using PubMed, PsycINFO, Scopus, Science Direct, EBSCO, and ERIC scientific databases using the following keywords: “perfectionism,” “feedback,” “instruction,” and their combinations. The date of publication for the literature sources was not specified under the search criteria. The source collection and SLR were conducted in October 2025 through the search protocol and study in accordance with the registration requirements of PROSPERO, under registration no. CRD420251015998. The selection of articles and the extraction of data followed a structured multistep procedure. The screening of studies and the extraction of data were conducted by two independent reviewers. Decision making followed a predefined procedure consisting of three steps: 1) each reviewer independently assessed the studies based on the established inclusion and exclusion criteria; 2) in cases of disagreement, a bilateral discussion was held to clarify the basis of the decision; and 3) if consensus could not be reached through discussion, a third expert was involved to adjudicate the final decision. An inter-rater reliability was not formally calculated as the decisions required qualitative judgment, and the heterogeneity and multidimensional nature of the included studies—addressing the interplay of intervention methods, feedback processes, and perfectionism—did not allow for consistent statistical coding. Reliability was ensured through independent assessment, consensus-based resolution, and, when necessary, the involvement of a third expert.

The inclusion criteria indicated that articles had been published in peer-reviewed journals and in English, containing a combination of the aforementioned keywords, in addition to discussing the relationship between feedback systems and perfectionism. As a further criterion, studies in which intervention trials were employed were selected.

Therefore, publications which fell under type segmentation of conference papers and volumes, theses, dissertations, chapters, and books; were not written in English; and did not involve any combination of the searched keywords nor were closely related to the issue of perfectionism and feedback systems in their entirety were excluded. Finally, based on the exclusion criteria, descriptive literature reviews, meta-analyses, or studies based solely on cross-sectional examinations without intervention were also removed. The focus on intervention studies was a deliberate methodological choice. Previous systematic reviews in the field of perfectionism have predominantly identified cross-sectional research and have consistently noted this as a limitation (32–34), while the broader literature has also highlighted the scarcity of longitudinal studies (27). In light of these considerations, the present review concentrated on intervention-based research that empirically examined the relationship between feedback systems and perfectionism. Accordingly, the search strategy employed keywords specifically related to feedback processes. Terms such as “parental expectations” and “parental criticism,” although closely linked to the dimensions of perfectionism, do not represent discrete feedback constructs and were therefore not suitable as specific search criteria for the scope of this review.

The inclusion of heterogeneous perfectionism measures reflects the theoretical diversity of the field, as no single definition or measurement approach has achieved consensus. Accordingly, previous systematic reviews have likewise integrated studies that employed multiple validated instruments (32–35), and the present review followed this established practice as limiting the synthesis to a single measure would substantially narrow the available empirical evidence.

A formal risk-of-bias or study quality assessment tool was not applied due to the heterogeneity of the study designs and the outcome measures across the included interventions, which precluded the use of a single standardized framework. Instead, the methodological strengths and weaknesses were evaluated narratively, and the implications of this approach are addressed in Section 4.5.

Emotional and cognitive reactions to negative feedback obtained more prominent emphasis in the studies. In response to negative feedback, maladaptive perfectionists showed a decrease in positive emotions (36, 37), an increase in negative emotions (37, 38), an elevated anxiety level (36), and a low self-esteem (36, 39). On the other hand, an inverse significant relationship with competence satisfaction was also reported (40). Furthermore, a significant relationship was found between perfectionist concerns and high life stress during post-examination follow-up, predicting an increase in depressive symptoms (38). On the contrary, some studies revealed no significant relationship between maladaptive perfectionism and affective reactivity related to negative feedback (41, 42). After similar negative feedback, those with adaptive perfectionism showed a decreased positive affect, an increased negative affect, and rumination (41). Individuals who scored high on both self-oriented perfectionism (SOP) and socially prescribed perfectionism (SPP) demonstrated strong significant predictors of increased shame and guilt affected by negative feedback following a series of competitive tasks (43), and a further significant relationship was detected with the absolute accuracy of predicting anger (44), suggesting that individuals with lower perfectionism are more accurate in predicting anger following failure.

In the positive feedback setting, both adaptive (41) and maladaptive (36) perfectionism maintained significant relationships with increased positive emotions and predicted self-evaluation of positive traits (37), whereas in maladaptive perfectionism combined with low self-confidence, the anxiety level increased as a consequence of positive feedback (36). Finally, several studies detected no traceable relationship with positive feedback on maladaptive perfectionism (38, 39). These patterns indicate that negative feedback may reliably elicit more detrimental emotional outcomes because it preferentially activates the psychological processes associated with a heightened threat appraisal and sensitivity to social evaluation. Beyond perfectionism itself, co-occurring mechanisms—such as a tendency toward self-critical cognitive styles, a reduced perceived control, or an elevated vulnerability to shame—can further intensify the negative affective responses. Such processes may help explain why negative feedback produces more consistent and severe emotional consequences across studies, irrespective of variations in the perfectionism profiles.

Multiple studies converged on similar outcomes showing that individuals with high SOP scores tended to choose the harder task at significantly greater frequency following positive feedback (39, 45), which also pertained to those with low SOP but high SPP scores (46). After negative feedback, the set goal was lowered (46), but no detectable correlation was found in this relation (39). The scores in the personal standards (PS) dimension generally correlated with goal settings, regardless of feedback, while the Clinical Perfectionism Questionnaire (CPQ) showed no significant relationship (47). Following positive feedback, participants with high SPP exhibited significantly higher levels of self-doubt, but only in public settings; in private, this pattern was not observed. In contrast, high levels of SOP were associated with significantly greater self-handicapping in all settings, whether private or public (48). Similarly indicating behavioral patterns in another study, functional perfectionists used point tracking representing feedback significantly more often during the game compared with dysfunctional perfectionists. In addition, the task condition manipulated in a competition context resulted in a stronger increase in the point monitoring frequency for functional perfectionists (49). It appears that positive feedback plays a salient role in the behavioral responses to different aspects of perfectionism.

As a consequence of negative feedback, subjects scoring higher at perfectionism performed considerably worse in the balancing tasks (50). Similarly, those with a combination of high perfectionistic strivings (PS) and perfectionistic concerns (PC) exhibited inferior performance on the golf task (51). Only those participants with high PS (perfectionistic strivings) and PC showed remarkable differences in reaction time: they showed faster reaction times after peer-comparative negative feedback than after self-comparative negative feedback (52). The fastest reaction time in the cognitive task performance among both adaptive and maladaptive perfectionists was also associated with negative feedback (53), although maladaptive perfectionists had faster reaction times than those in the adaptive and non-adaptive groups, demonstrably through strong significance and regardless of the direction of feedback. In absolute accordance with the previous result, and also independent of the feedback direction, the response times of adaptive perfectionists to tasks were notably longer compared with those of the other groups (54). While it became clearly apparent in the sports tasks that the increased presence of perfectionist concerns accompanied with negative feedback has performance-degrading effects, adaptive perfectionists may more likely display slower reaction times due to their preference for precision and accuracy, at the expense of time.

Numerous studies have demonstrated a correlation between perfectionism and physiological stress responses, particularly concerning the effect of negative feedback. High-level adequacy to social expectations (SPP) combined with a low self-confidence resulted in a significant increase in heart rate and showed a significant correlation with systolic blood pressure increase in response to negative feedback alone, whereas the impacts were slighter or absent in response to positive feedback (36). In contrast to other studies, perfectionists did not show significantly lower heart rate variability under stress compared with either the control group or their baseline values, indicating different patterns of physiological adaptation to stress (55). In another study of patients diagnosed with anorexia nervosa, the dorsal anterior cingulate cortex (dACC) activation was augmented in response to negative feedback, showing significant positive correlation with perfectionism, whereas this relationship was not observed in the control group (56). Furthermore, adaptive perfectionists reacted to negative feedback with significantly higher feedback-related negativity (FRN) amplitudes than in maladaptive perfectionists, indicating different patterns of neurocognitive processing (54). Such findings suggest that negative feedback may evoke more detrimental physiological outcomes as it preferentially activates threat-related neurobiological systems. Beyond perfectionism itself, co-occurring mechanisms—such as a heightened sensitivity to social evaluation, intolerance of uncertainty, or generally elevated threat-appraisal tendencies—can similarly amplify autonomic and neural stress responses. These pathways may help explain why negative feedback consistently produces stronger biomarker reactivity across studies, even when the perfectionism levels vary.

Of the 24 included studies, half of the interventions used a two-way instruction, therefore accompanied by both negative and positive feedbacks in these experiments.

The included literature also covered three studies representing different interventions as they applied an educational model, a specific form of assessment, or a personalized feedback method designed for perfectionists instead of bipolar positive or negative feedback. Relevant studies evaluated the impacts of these approaches.

One of the interventions, which implemented the MooN program (a physical education program), revealed a small effect but significant difference for self-reported perfectionism, although the mean value of the Perfectionism Scale did not show significant differences in the experimental group compared with the control group (57). Another impact study on exerting the influence of perfectionism among students learning English as a foreign language found no significant differences between the application of the interactionist dynamic assessment, the interventionist dynamic assessment, and the traditional education method (58). Finally, a third study, employing a method developed specifically for perfectionists, showed significantly increased self-affirmation, coping self-efficacy, and problem-focused coping in addition to decreased depressive and anxiety symptoms as a result of the intervention among perfectionists in the intervention group compared with the control group (59). In terms of the positive outcomes on perfectionism, there have been no studies in public education, but interventions among students in higher education have been confirmed successful. The sample sizes of these studies were similar; however, not only the sex ratio but also the age range of the participants differed. Thus, the results may have been potentially influenced by maturity of personality. Nevertheless, the methodology was the main difference between studies as only one intervention can be identified as specifically designed to address the issue of perfectionism.

Analysis of the articles was conducted based on four categories of limitations: the valence of feedback, the nature of the tasks performed by participants, the questionnaires used to assess perfectionism, and the generalizability of the findings to the sample populations. Information explicitly reported by the authors in the results sections of the articles was automatically included in the limitations summary table. In cases where no clear statement with regard to limitations or study weaknesses was provided, the decision to enter a “yes” or a “no” value in the respective field was made based on (60) consensus among the authors. As all of the included studies employed intervention-based methodologies, the sample sizes were generally small, and such small samples further limit the statistical power and robustness of the reported effects. While a few studies conducted prior sample size calculations and designed their research accordingly, this approach was not typical across the majority of the studies. During the screening process, only English-language publications were included; however, these originated from both Eastern and Western cultures, allowing for a degree of international generalizability. It is important to note, however, that 17 of the 24 studies utilized samples composed of university students, which limits the generalizability of the findings primarily to this population. This limitation is further compounded by the fact that university student samples are relatively homogeneous in demographic and psychological characteristics and differ in several respects from the general population (61). Prior methodological analyses have demonstrated that such samples possess specific cognitive and motivational profiles, which may introduce population bias and reduce external validity (62). Moreover, the manifestation of perfectionism may vary across ages, genders, and cultural backgrounds (63–65). Accordingly, the mechanisms identified in the present review are primarily applicable to student populations. Further research is needed to determine the extent to which these processes appear in different age groups, cultural contexts, or professional populations. The majority of the analyzed studies, with a few exceptions, investigated the complexity of the perfectionism construct using validated questionnaires. However, the included studies employed a variety of validated perfectionism measures that differ in their underlying theoretical emphases and assessed dimensions. This measurement heterogeneity limits the direct comparability of the intervention outcomes and therefore warrants cautious interpretation of the synthesized findings. In line with this, the review relied on narrative rather than quantitative synthesis as the variability in the outcome measures and the methodological approaches did not allow for a meaningful aggregation or a meta-analytic calculation of effect sizes. As a result, the magnitude of the reported associations could not be synthesized quantitatively; however, the narrative patterns identified across studies still allowed for meaningful interpretation of the relationship between feedback and perfectionism. A formal risk of bias assessment was not conducted, which represents a methodological limitation of the review. In addition, the possibility of publication bias cannot be ruled out as studies with null or non-significant findings may be underrepresented in the available literature. In conclusion, the predominance of positive values in the limitation table (Table 2) suggests that the mechanism identified in the experimental studies between perfectionism and feedback systems can be considered generalizable—primarily to university student populations.

The Bibliometric–Systematic Literature Review (B-SLR) approach builds on the integration of the PRISMA protocol with other established tools and frameworks to address the disconnections between bibliometric analyses, SLRs, and theory development (66). In alignment with the 10th step of the B-SLR—i.e., developing a theoretical contribution—a corresponding theoretical framework was developed. The theoretical model constructed on the basis of the results and our conclusions, illustrating the mechanism by which positive and negative feedbacks affect the dimensions of perfectionism, is presented in Figure 2.

A theoretical grounding for the model is provided by two influential frameworks on perfectionism and feedback processing. Firstly, the multidimensional model of perfectionism proposed by Frost et al. (20) highlights the heightened emotional vulnerability characteristic of maladaptive dimensions—particularly the concern over mistakes and doubts about actions. This perspective helps explain why negative feedback produces a more consistent and a pronounced cognitive and emotional deterioration among individuals high in maladaptive perfectionism. Secondly, the dual process model developed by Slade and Owens (67), which is rooted in reinforcement theory, which posits that the adaptive and maladaptive forms of perfectionism are maintained by distinct motivational processes: adaptive perfectionism is more responsive to positive reinforcement, whereas maladaptive perfectionism is sustained primarily through negative reinforcement cycles. This framework aligns closely with the patterns reflected in our model, namely, that the consequences of negative feedback are more stable and detrimental, whereas the effects of positive feedback are less predictable and not uniformly beneficial.

Psychological and physiological consequences are evident in both the adaptive and maladaptive forms of perfectionism in response to feedback. However, the performance decline appears to be associated exclusively with the maladaptive perfectionism when exposed to negative feedback. In contrast, adaptive perfectionism in the context of positive feedback may lead to behavioral changes in multiple directions, potentially encompassing both positive and negative shifts.

The model does not reflect a symmetrical impact of feedback valence across the two perfectionism subtypes. Specifically, positive feedback is not linked to maladaptive perfectionism, as we concluded during the theoretical model development process that no stable or consistent outcomes can be derived from such an association. Overall, the consequences depicted in the theoretical model are predominantly negative in nature: this is reflected in the stress-induced biomarker reactivity, the emotional deterioration, and the decline in performance.
