<abstract>
<p>While facilitating factors to learning at the workplace have been well investigated, throughout the past decade less has emerged about the barriers that occur when approaching a learning activity at the workplace. Barriers to learning at the workplace are factors that hinder the initiation of successful learning, interrupt learning possibilities, delay proceedings or end learning activities much earlier than intended. The aim of this study is to develop and validate an instrument that measures barriers to informal and formal learning at the workplace. An interview pre-study asked 26 consultants about their learning barriers based on existing instruments. Using this data as groundwork, a novel measuring instrument of barriers to informal and formal learning was developed. The instrument is comprised of five factors with items on individual barriers, organizational/structural barriers, technical barriers, change and uncertainty. To validate the scales, a cross-sectional questionnaire with 112 consultancy employees and freelancers was conducted. The validation included exploratory factor analysis, internal consistency assessment, confirmatory factor analysis (CFA) and convergent validity assessment. The results generated a three-factor scale barrier measurement for formal learning and a two-factor scale barrier measurement for informal learning. All scales featured Cronbach&#x2019;s alpha values ranging between 0.80 and 0.86. With this developed and validated scales it is intended to help offer insights into factors that hinder individuals from learning at the workplace, and show organizations their potential for change.</p>

<title>Introduction</title>
<p>The factors facilitating learning at the workplace have been well investigated (<xref ref-type="bibr" rid="B49">Kyndt et al., 2018</xref>), less is known about barriers that occur when approaching a learning activity at the workplace (<xref ref-type="bibr" rid="B11">Boeren, 2016</xref>). Based on <xref ref-type="bibr" rid="B86">Tynj&#x00E4;l&#x00E4;&#x2019;s (2008)</xref> conceptualization of workplace learning, learning can be formal, non-formal or informal; emerge in a deliberate or unplanned setting; and occur on the individual, team or organizational level (<xref ref-type="bibr" rid="B78">Segers et al., 2021</xref>). Informal learning at the workplace can be defined as a process that is not organized, controlled or structured by individuals or an institution, thereby rendering it unintended learning from experience that occurs in a situation that is meaningful to the learner (<xref ref-type="bibr" rid="B65">Neaman and Marsick, 2018</xref>; <xref ref-type="bibr" rid="B31">Hager, 2019</xref>). Informal learning usually does not lead to credentials either, in contrast with formal learning, which focuses on achieving certifications or degrees and is well-structured, embedded in institutions and taught according to a curriculum (<xref ref-type="bibr" rid="B58">Marsick and Watkins, 2001</xref>; <xref ref-type="bibr" rid="B53">Lecat et al., 2020</xref>; <xref ref-type="bibr" rid="B75">Rodriguez-Gomez et al., 2020</xref>).</p>
<p>Barriers to learning at the workplace form a holistic set of missing individual, team and organizational aspects. They are factors that hinder the initiation of successful learning, interrupt learning possibilities, delay proceedings or end learning activities much earlier than intended (<xref ref-type="bibr" rid="B19">Crouse et al., 2011</xref>). Most of the existing instruments that measure learning barriers or inhibitors have a primary focus on the organizational level (<xref ref-type="bibr" rid="B27">Eken et al., 2020</xref>; <xref ref-type="bibr" rid="B45">Kezar and Holcombe, 2020</xref>; <xref ref-type="bibr" rid="B3">Allen and Heredia, 2021</xref>), specific individual concepts such as anxiety (<xref ref-type="bibr" rid="B74">Piscitelli, 2021</xref>) or preferences for new technologies (<xref ref-type="bibr" rid="B33">He and Yang, 2021</xref>). Upon identifying barriers, then, it soon becomes clear that well-reviewed facilitating factors and learning conditions are what raise the question of what to add or foster to bolster learning outcomes and thus overcome the expected learning barriers (e.g., <xref ref-type="bibr" rid="B15">Cerasoli et al., 2018</xref>; <xref ref-type="bibr" rid="B39">Jeong et al., 2018</xref>; <xref ref-type="bibr" rid="B49">Kyndt et al., 2018</xref>). Such solutions could be more equipment, a better team climate or more possibilities to learn. <xref ref-type="bibr" rid="B22">Decius et al. (2021)</xref> highlighted that employee characteristics and the learning culture in the organization are important in investigating learning.</p>
<p>Learning facilitators and barriers can be opponents (<xref ref-type="bibr" rid="B15">Cerasoli et al., 2018</xref>), such as when more equipment is regarded as a facilitator and current equipment at the workplace as a barrier to learning activities (<xref ref-type="bibr" rid="B54">Louws et al., 2017</xref>; <xref ref-type="bibr" rid="B44">Keck Frei et al., 2021</xref>). This indicates that facilitators and barriers to learning are not of universal application. It is rather based on individual or team related concepts and assumption. What hinders one group of learners could be a facilitator for another, such as time pressure or the provision of certain resources in an office learning environment. Learning barriers lead to the question of what is not working well and should be changed, like miscommunication, poor work environment or lack of autonomy (<xref ref-type="bibr" rid="B12">Brion, 2021</xref>; <xref ref-type="bibr" rid="B22">Decius et al., 2021</xref>; <xref ref-type="bibr" rid="B46">Kim et al., 2021</xref>). This can only be spotlighted when considering the complexity of barriers at the workplace. To best investigate barriers at the workplace, the investigated domains at the workplace should include different aspects of knowledge-intensive service work, should deal with multiple demands and offer the possibility to solve problems in various ways. The consultancy, is suitable in this regard due to its special focus on multiple, complex and challenging work environments; the complexity of tasks; the high variety of solution strategies; and its diverse career development paths (<xref ref-type="bibr" rid="B47">Korster, 2022</xref>). These characteristics fall in line with a constant need for professional development and lifelong learning to keep up with the magnificent and ill-structured problems occurring at the workplace (<xref ref-type="bibr" rid="B69">O&#x2019;Leary, 2020</xref>; <xref ref-type="bibr" rid="B23">Dolata et al., 2021</xref>). The required competences of consultants are diverse and dynamic as well (<xref ref-type="bibr" rid="B90">Wi&#x00DF;hak and Hochholdinger, 2020</xref>; <xref ref-type="bibr" rid="B34">Helens-Hart and Engstrom, 2021</xref>; <xref ref-type="bibr" rid="B87">van der Baan et al., 2022</xref>). Thus, learning is essential to managing the multiple demands and challenges at the workplace in this domain (<xref ref-type="bibr" rid="B26">Dymock and Tyler, 2018</xref>), to which interruptions, limitations or barriers can be a serious threat.</p>
<p>In reflection of the assorted barriers that can arise in these varied scenarios, research on barriers to learning form a continuum based on individual learning experiences, situations and roles. Moreover, to fully understand learning activities, it is necessary to reflect on facilitators and barriers equally. Accordingly, based on the explorative interview study (<xref ref-type="bibr" rid="B100">Anselmann, in press</xref>) and results and existing concepts from <xref ref-type="bibr" rid="B8">Belling et al. (2004)</xref> and <xref ref-type="bibr" rid="B19">Crouse et al. (2011)</xref>, the aim of this present study is to develop and validate a measurement instrument of barriers to informal and formal learning at the workplace.</p>

<title>Barriers to learning</title>
<p>Barriers to learning at the workplace are factors that hinder the initiation of successful learning, interrupt learning possibilities, delay learning proceedings or end learning activities much earlier than intended (<xref ref-type="bibr" rid="B19">Crouse et al., 2011</xref>). Regarding hierarchy, barriers can occur on the individual, team or organizational level. Research indicates that motivational factors (<xref ref-type="bibr" rid="B68">Nouwen et al., 2022</xref>), social interactions (e.g., <xref ref-type="bibr" rid="B61">Mishra, 2020</xref>), the general structure or equipment of the workplace (<xref ref-type="bibr" rid="B10">Billett, 2022</xref>; <xref ref-type="bibr" rid="B29">Goller and Paloniemi, 2022</xref>) and further career development (<xref ref-type="bibr" rid="B59">Matusik et al., 2022</xref>) can all be learning barriers. In turn, these barriers can be external, internal or refer to problems with organizational fit. Barriers to learning at the workplace can be external, internal or refer to problems with organizational fit (<xref ref-type="bibr" rid="B40">Johnson et al., 2018</xref>; <xref ref-type="bibr" rid="B66">Nel and Linde, 2019</xref>).</p>
<p>External barriers are restrictions to learning through authoritative knowledge (<xref ref-type="bibr" rid="B41">Jordan, 2014</xref>) or bounded agency (<xref ref-type="bibr" rid="B29">Goller and Paloniemi, 2022</xref>). Internal learning barriers can be found, for instance, in personal ideas and concepts which determine how, where, in which frequency and for what reason learning activities are engaged or dismissed (<xref ref-type="bibr" rid="B31">Hager, 2019</xref>). Fitting problems, meanwhile, refer mainly to external barriers that create physical, cognitive or emotional separations from work tasks (<xref ref-type="bibr" rid="B2">Alikaj et al., 2021</xref>; <xref ref-type="bibr" rid="B71">Papacharalampous and Papadimitriou, 2021</xref>). They are regarded as the alienation between learners and their daily work tasks, indicating that fitting problems can be a negative consequence of barriers occurring in an organizational structure. One example of a fitting problem is when employees do not apply organizational rules in a standardized process because they believe they are non-functional or do not fit their own work preferences. The results of non-engagement in learning activities can lead to limited daily work tasks or long-term unachievable targets (<xref ref-type="bibr" rid="B2">Alikaj et al., 2021</xref>; <xref ref-type="bibr" rid="B71">Papacharalampous and Papadimitriou, 2021</xref>).</p>
<p>While a constant need for life-long learning is addressed multiple times, an engagement in learning activities, does not emerge from itself. Participation and engagement in learning depend on the results of cognitive, emotional and behavioral engagement and evaluations in learning activities themselves (<xref ref-type="bibr" rid="B80">Shuck and Herd, 2012</xref>), which are determined by external and internal barriers, as well as fitting problems. The results of non-engagement in learning activities can lead to limited daily work tasks or long-term unachievable targets (<xref ref-type="bibr" rid="B79">Shuck, 2019</xref>).</p>

<sec id="S2.SS2">
<title>Informal and formal learning</title>
<p>Daily situations at the workplace offer opportunities for informal learning. <italic>Informal learning</italic> is understood as a process that can be deliberate or reactive and leads to acquiring of competence (<xref ref-type="bibr" rid="B81">Simons and Ruijters, 2004</xref>). Furthermore, <xref ref-type="bibr" rid="B58">Marsick and Watkins (2001)</xref> outline that informal learning is &#x201C;usually intentional but not highly structured&#x201D; and can include &#x201C;self-directed learning, networking, coaching, mentoring&#x201D; (<xref ref-type="bibr" rid="B58">Marsick and Watkins, 2001</xref>, p. 25&#x2013;26). It occurs individually or socially outside organized learning settings. Informal learning is also influenced by the characteristics of individuals, workplaces and organizations (e.g., self-efficacy, leadership, feedback; <xref ref-type="bibr" rid="B39">Jeong et al., 2018</xref>). In contrast, <xref ref-type="bibr" rid="B58">Marsick and Watkins (2001)</xref> define <italic>formal learning</italic> as &#x201C;typically institutionally sponsored, classroom-based, and highly structured (<xref ref-type="bibr" rid="B58">Marsick and Watkins, 2001</xref>, p. 25).</p>
</sec>
<sec id="S2.SS3">
<title>Workplace learning</title>
<p>Emphasis on the workplace as a place of learning already occurs in <xref ref-type="bibr" rid="B6">Argyris and Sch&#x00F6;n (1996)</xref>, where the researchers subdivide the actions occurring in the workplace into knowing in action, knowing what to do in a situation and reflecting in action, or thinking about steps to take. Throughout the last few decades, the workplace has emerged from &#x201C;<italic>an environment not only where learning new knowledge and skills can happen but where learning should be happening. However, despite its ever-increasing importance, there is no broad consensus on what workplace learning is, with many definitions simply stating that it involves all learning that happens at the workplace</italic>&#x201D; (<xref ref-type="bibr" rid="B43">Kankara&#x0161;, 2021</xref>, p. 9). Based on these considerations, a number of other concepts were emerged and divided into workplace learning (<xref ref-type="bibr" rid="B9">Billett, 1995</xref>) and work-related learning (<xref ref-type="bibr" rid="B85">Streumer and Kho, 2006</xref>). <xref ref-type="bibr" rid="B10">Billett (2022)</xref> assumes that workplace learning and actions follow a structure based on work experience. In this context, learning activities are neither formal, nor incidental, nor unstructured, nor spontaneously directed. On the contrary, they are determined by the requirements of the workplace. The individual and contextual factors that condition the workplace learning thereby function as determinants of workplace learning. <xref ref-type="bibr" rid="B24">Doornbos et al. (2008)</xref> similarly break down work-related learning into three components: process, learning environment and outcome of the process. Work-related learning is considered to be a predominantly explicit process that is guided by predefined learning objectives. In turn, learning itself is understood as a cognitive and rational process that takes place in an environment characterized by a certain structure (<xref ref-type="bibr" rid="B10">Billett, 2022</xref>). Guidance and control of knowledge access are passed on and reviewed by authorities, and the result of this process is a competent individual increase in knowledge and skills.</p>
<p><xref ref-type="bibr" rid="B38">Jacobs and Park (2009)</xref> summarize the divergently occurring processes of workplace learning through the metaphor of learning cells. Learning events may occur singly or in majority in the workplace or in situations associated with it, all referred to as cells. Each of these cells reflects experiences and learning actions that may emerge in the work context under certain conditions. Learning at the workplace can thus be interpreted as learning for the workplace: the actions initiated serve and improve the skills that may be necessary to perform the job (<xref ref-type="bibr" rid="B78">Segers et al., 2021</xref>). In the context of informal learning, the workplace is particularly relevant with its requirement of continuous employee development. <xref ref-type="bibr" rid="B57">Marsick and Watkins (2015)</xref> even list informal learning as one of two learning forms that predominantly occur in the workplace, with the other being incidental learning.</p>
<p>In summary, learning at the workplace can be characterized as taking place both on the job and off the job (<xref ref-type="bibr" rid="B31">Hager, 2019</xref>), thereby indicating that learning content is linked to the requirements of the job. Informal learning on the job, according to <xref ref-type="bibr" rid="B31">Hager (2019)</xref>, is mainly contextual and work- and experience-based, and furthermore stems from situations in which learning is not the main goal. The situation is usually initiated by the learning environment itself or the individuals who are learning, rather than by teachers or trainers, and is often socially shared. These learning actions and concepts of workplace learning outline the practical framework in which learning at the workplace can take place.</p>

<title>Pre-study</title>
<p>In a pre-study, interviews with 26 consultants (<italic>N</italic> = 26) were conducted to find out what are the learning barriers to informal and formal learning (<xref ref-type="bibr" rid="B100">Anselmann, in press</xref>). The theoretical deduced semi-structured interviews were conducted <italic>via</italic> phone, Zoom, or Skype and lasted between 17 and 45 min (<italic>M</italic> = 29:17 min; <italic>SD</italic> = 6:23 min), they were recorded and transcribed. The interview guidelines were developed based on the definition of learning conditions in the workplace (<xref ref-type="bibr" rid="B83">Skule, 2004</xref>; <xref ref-type="bibr" rid="B39">Jeong et al., 2018</xref>), formal and informal learning activities (<xref ref-type="bibr" rid="B81">Simons and Ruijters, 2004</xref>), and barriers to learning (<xref ref-type="bibr" rid="B19">Crouse et al., 2011</xref>). Throughout the whole process of data collection, transcription, interpretation, and storing, EU General Data Protection Regulation (GDPR) rules were followed. In addition, a procedure index was established and approved by the researchers&#x2019; universities&#x2019; data protection officers.</p>
<p>The results revealed both external barriers, such as vague supervisor requirements, and internal barriers, such as disruptions from clients or supervisors, with additional subcategories for internal barriers like organizational fit (e.g., ineffective IT) and individual barriers (e.g., uncertainty). <xref ref-type="table" rid="T1">Table 1</xref> shows all identified internal and external barriers on the individual, team and organizational levels, as well as denotes the most common of these barriers.</p>

<p>Accordingly, 26 items on perceived barriers and 17 items measuring facilitators linked to the transfer of learning from <xref ref-type="bibr" rid="B8">Belling et al.&#x2019;s (2004)</xref> instrument were used to construct the newly questionnaire. The new developed questionnaire referred to a number of common barriers like lack of support (especially lack of managerial support), missing criteria for a clear organizational structure and hierarchy, mechanism of workplace curricular and hidden agendas, and pressure to work with limited resources and knowledge. The items used for the new measurement instrument also feature topics such as pressure to give priority to &#x201C;bottom line,&#x201D; short-term, financial targets; lack of resources to implement new ideas/plans from the program; and too many changes in the workforce. The items were rephrased and embedded to fit the overall concept of the questionnaire.</p>
<p>Another source that has been taken into account has been <xref ref-type="bibr" rid="B19">Crouse et al. (2011)</xref>. Their research focused on factors that hindering learning at the workplace in a qualitative study. The study highlights learning strategies, barriers, facilitators and potential outcomes of learning activities. From this study, 46 potential barriers that can be divided into nine categories of hindering factors (source constraints, lack of access, technological constraints, personal constraints, interpersonal constraints, structural and cultural constraints, course/learning content and delivery, power relationships and change) were used. Examples of these barriers are no managerial commitment to learning (structural and cultural constraints), cynicism/reluctance toward learning (personal constraints) and limited decision-making power in organizational affairs (power relations). The identified areas were reformulated into items and optimized for the new questionnaire context.</p>

<title>Preliminary questionnaire</title>
<p>Based on the described framework (internal barriers, external barriers and fitting problems), the results of the interview study (<xref ref-type="bibr" rid="B100">Anselmann, in press</xref>) and existing research (<xref ref-type="bibr" rid="B8">Belling et al., 2004</xref>; <xref ref-type="bibr" rid="B19">Crouse et al., 2011</xref>), an instrument to measure learning barriers was developed. The instrument includes scales regarding informal learning, formal learning and both. The questionnaire consists of 89 items measured on a 5-point Likert scale (1 = totally disagree, 5 = totally agree). Following the arguments of <xref ref-type="bibr" rid="B7">Babakus and Mangold (1992)</xref>; <xref ref-type="bibr" rid="B20">Dawes (2008)</xref> and <xref ref-type="bibr" rid="B76">Saleh and Bista (2017)</xref>, a 5-point Likert scale was preferred for three reasons: (1) to increase the response rate, (2) to increase the quality within the responses, especially for longer sections, and (3) to reduce participant frustration. The questionnaire features structural and organizational relations, as well as individual components. The nine categories cover resource constraints (10 items, item example: &#x201C;In my organization, there are financial constraints such as a continuing education budget to attend continuing education.&#x201D;), insufficient access (6 items, item example: &#x201C;Because of my educational qualifications, I do not have access to continuing education opportunities.&#x201D;), individual components (14 items, item example: &#x201C;I find it difficult to perceive my own learning needs.&#x201D;), team or interpersonal constraints (10 items, item example: &#x201C;I am often interrupted by colleagues during my work.&#x201D;), structural, cultural or organizational constraints (20 items, item example: &#x201C;In my organization, management does not promote learning opportunities.&#x201D;), course or learning content and delivery (6 items, item example: &#x201C;I think in further education or training, I can only gain inappropriate knowledge.&#x201D;), hierarchical relationships (4 items, item example: &#x201C;Resistance from others prevents me from participating in continuing education or training.&#x201D;), change (3 items, item example: &#x201C;Business goals in my organization change quickly.&#x201D;), technical limitations (6 items, item example: &#x201C;I have limited IT resources at my workplace, e.g., lack of software, limited platform access, inadequate hardware.&#x201D;) and unclear career perspective (10 items, item example: &#x201C;I can&#x2019;t assess the career opportunities available to me.&#x201D;). Furthermore the categories refer to barriers to formal learning (47 items) and barriers to informal learning (42 items).</p>

<title>Validation of the measurement instrument</title>
<sec id="S3.SS2.SSS1">
<title>Method</title>
<p>The validation of the before described measurement instrument follows the concept of <xref ref-type="bibr" rid="B35">Hinkin (1998); Moosbrugger and Schermelleh-Engel (2012)</xref> and <xref ref-type="bibr" rid="B73">Petri et al. (2015)</xref>. Their recommendations refer to a set of fundamental requirements for ensuring the quality and validation of the analytical procedure. Aiming to prove that the instrument meet the required standards for newly designed measurements (<xref ref-type="bibr" rid="B17">Cohen et al., 2018</xref>). This will cover Kaiser-Meyer-Olkin (KMO) and the Bartlett&#x2019;s Sphericity Test (BTS) determine the samples ability to run a factor analysis, explorative factor analysis (EFA), taking care of the reliability by using Cronbach&#x2019;s alpha, using convergent validity to detect correlations within different scales, and finally a confirmatory factor analysis (CFA).</p>
<p>To validate the measurement instrument, an online questionnaire was developed. The questionnaire combined four scales (researchers&#x2019; own development; <xref ref-type="bibr" rid="B84">Spector, 1985</xref>; <xref ref-type="bibr" rid="B72">Peng, 2013</xref>; <xref ref-type="bibr" rid="B21">Decius et al., 2019</xref>) and several personal background variables, such as education level, expertise, years in the current position, gender and participation in formal training. The first scale refers to barriers to learning (researchers&#x2019; own development) with 89 items. This set of items is the preliminary version of the barriers to learning scale and covers the fields described in 3.1.3. The second scale relates to the informal workplace component scale (IWC) by <xref ref-type="bibr" rid="B21">Decius et al. (2019)</xref>. Here 24 items cover the wide range of informal workplace learning. The third scale deals with the concept of hiding knowledge within a company (<xref ref-type="bibr" rid="B72">Peng, 2013</xref>). 14 items measure why and when employees hide knowledge within daily work situation. The forth scale relies on Spectors&#x2019; (1985) job satisfaction survey. Within this scale 38 items are used to identify how satisfied employees are with their working conditions, their career options as well as their supervisors.</p>
<p>The process time of the online questionnaire took the participants around 20 min. The participants were acquired by using social media channels like Linkedin, Xing, or Facebook, as well as relevant groups and blogs. To identify possible participants from consultancy keywords were used, such as &#x201C;HR consultancy,&#x201D; &#x201C;outplacement consultancy,&#x201D; &#x201C;recruitment,&#x201D; &#x201C;human resource development,&#x201D; &#x201C;professional training&#x201D; and &#x201C;professional coaching.&#x201D;</p>
<p>In a next step the consultants were contacted by mail, sending an invitation to the questionnaire, followed by a short primer and a summary of facts. A kind reminder has been send 2 weeks after the first e-mail contact.</p>
</sec>
<sec id="S3.SS2.SSS2">
<title>Sample</title>
<p>The participants came from the consultancy domain. They are varied in position and jobs, and worked in different fields throughout Germany, such as human resource development (HRD) or HR, recruiting, automotive and strategic management consulting. The sample consisted of 112 participants, of which 58.7% were female and 40.3% male. In sum, 91 permanent employees took part in the survey; the remaining 21 were freelancing professionals. Their workplaces were settled in small and medium sized companies, as well as in nationwide and internal operating enterprises. Their average work experience was 12.29 years with a standard deviation of 9.18 years. The consultants worked in different domains with different backgrounds and showed great variation in educational level, tasks and decision-making authority. Throughout the whole process of data collection, calculation, interpretation and storing, the EU GDPR rules were followed. In addition, a procedure index was established and approved by the researchers&#x2019; universities&#x2019; data protection officers. Furthermore, the questionnaire, as well as the whole research process was approved by the universities&#x2019; ethic committee with a positive vote without constraints.</p>

<sec id="S3.SS2.SSS3">
<title>Data analysis</title>
<p>Based on <xref ref-type="bibr" rid="B35">Hinkin&#x2019;s (1998)</xref> framework for scale validation and in close liaison with <xref ref-type="bibr" rid="B63">Moosbrugger and Schermelleh-Engel (2012)</xref>, four major methods to determine the scale&#x2019;s validity were used: exploratory factor analysis (EFA; oblique rotation), an internal consistency assessment (Cronbach&#x2019;s alpha and McDonald&#x2019;s omega), CFA and a convergent validity assessment. To analyze the data SPSS (IBM SPSS Statistics 27) and Mplus (Mplus Version 8.7) were used.</p>
<p>Regarding the EFA, it has been conducted with oblique rotation (<xref ref-type="bibr" rid="B70">Osborne, 2015</xref>), based on the assumption of having correlations between the factors. As proposed by <xref ref-type="bibr" rid="B18">Costello and Osborne (2005)</xref> the cut off point for items has been a factor loading below 0.40.</p>
<p>Referring to <xref ref-type="bibr" rid="B62">Mondiana et al. (2018)</xref> KMO and the BTS determine the samples ability to run a factor analysis. In this sample the values of KMO and BTS both highly indicate this ability. According to <xref ref-type="bibr" rid="B62">Mondiana et al. (2018)</xref> the sample is suitable when reaching a KMO over 0.60 and the BTS should be at &#x03B1; &#x003C; 0.05. Here the KMO is at 0.80 and the BTS is 0.000. This indicated the high quality of the sample.</p>
<p>The measurement has been conducted with Mplus (Mplus Version 8.7). For the CFA SPSS (IBM SPSS Statistics 27) has been used. CFI measurements compare the extent to which the model is better than the assumption that all variables are uncorrelated. <xref ref-type="bibr" rid="B36">Hu and Bentler (1999)</xref> recommend values above 0.90. The fit indices were measured by referring to RMSEA. This describes how closely the correlation matrix implied by the model, matches the correlation matrix found in the data. The smaller the RMSEA values, the better the calculated values match those actually found. <xref ref-type="bibr" rid="B36">Hu and Bentler (1999)</xref> recommend that the value for RMSEA should be less than 0.05. The correlation analysis relies on Crombach&#x2019;s alpha and McDonald&#x2019;s omega, using SPSS (IBM SPSS Statistics 27). The internal consistency of a scale as a measure of reliability is usually indicated by Cronbach&#x2019;s alpha. Increasingly, however, the coefficient McDonald&#x2019;s Omega is appearing for this purpose.</p>
<p>Within the measurement, data cleaning has been applied, using EDC-technique for data cleaning (<xref ref-type="bibr" rid="B48">Krishnamoorthy et al., 2014</xref>). The results show that there are less than 1% of missing data. In these cases, single imputation <italic>via</italic> regression provided by SPSS (<xref ref-type="bibr" rid="B89">Weaver and Maxwell, 2014</xref>) has been used.</p>

<title>Exploratory factor analysis</title>
<p>The EFA was using the preliminary questionnaire, which contained 89 items within 10 factors divided into formal and informal barriers. This step aims to reduce the number of items and factors, and thus conducted several more EFA rounds. The final EFA resulted in a suitable and practical questionnaire for barriers at the workplace. The results are presented in <xref ref-type="table" rid="T3">Table 3</xref>, yielded a three-factor scale for the barriers to formal learning (individual, organizational/structural/hierarchical and technical barriers) and a two-factor scale for the barriers to informal learning (individual and structural barriers).</p>

<p>In addition to the factor loadings, the average variance extracted (AVE) has been calculated using SPSS 27 and Excel. The AVE is a measure of the quality of how a single latent variable explains its indicators. Here, the variance of each indicator is decomposed into the variance, the squared regression coefficient, explained by the latent variable, and an error not explained by the construct. For this factor the AVE is 0.61. Scores above 0.50 are regarded suitable (<xref ref-type="bibr" rid="B25">dos Santos and Cirillo, 2021</xref>). Furthermore the calculated composite reliability is at 0.93. Composite reliability can be used as an additional measurement to assess the internal consistency of items within one factor. Values above 0.70 are regarded as necessary for a suitable construct (<xref ref-type="bibr" rid="B42">Kalkbrenner, 2021</xref>).</p>
<p>According to <xref ref-type="bibr" rid="B1">Ahire and Devaraj (2001)</xref> different statistical methods can be used to estimate different types of validity. As suggested by many authors (<xref ref-type="bibr" rid="B13">Brown, 2015</xref>; <xref ref-type="bibr" rid="B64">Muth&#x00E9;n and Muth&#x00E9;n, 2017</xref>; <xref ref-type="bibr" rid="B50">Kyriazos, 2018a</xref>) it is an adequate way for confirm the EFA-structure with the CFA-method. CFA could also be used to assess discriminant validity. For factors measuring barriers to formal learning (individual components AVE 0.61, CR 0.93/technical limitations AVE 0.72, CR 0.88/organizational limitations and power relations AVE 0.60, CR 0.82) and for factors measuring barriers to informal learning (individual components AVE 0.61; CR 0.70; structural components AVE 0.68, CR 0.88) average variance reliability and composite reliability has been estimated and checked for the intercorrelation of factor loadings. For all factors estimates are acceptable and there are no greater correlations as estimates of AVE. <xref ref-type="table" rid="T4">Tables 4</xref>, <xref ref-type="table" rid="T5">5</xref> give an overview about the measuring and the values.</p>

Referring to <xref ref-type="bibr" rid="B51">Kyriazos (2018b)</xref> the models goodness of fit is more than acceptable. This is underpinned by RMSEA = 0.06 for formal barriers to learning and a RMSEA = 0.065 for barriers to informal learning.</p>

<p>The measurement model of barriers to learning consists of formal barriers to learning with its factors individual components formal setting (IC_F), organizational limitations and power relations (OL) and technical limitations (TL), as well as of informal barriers to learning with its factors individual components informal setting (IC_IF) and structural components (SC). The measurement model for the barrier scale for formal learning have the following fit indices: &#x03C7;<sup>2</sup> = 324.243; df = 234; &#x03C7;<sup>2</sup>/df = 1.06; CFI = 0.90; RMSEA = 0.06; and TLI = 0.88. The fit indices of the measurement model for the barrier scale for informal learning are &#x03C7;<sup>2</sup> = 210.027; df = 144; &#x03C7;<sup>2</sup>/df = 1.02; CFI = 0.92; RMSEA = 0.065; and TLI = 0.89.</p>

<title>Convergent validity</title>
<p>The assessment of the convergent validity was quite difficult, because there are no instruments comparable to the newly designed measurement of barriers to learning. Therefore, it was compared to the IWC (<xref ref-type="bibr" rid="B21">Decius et al., 2019</xref>), hiding knowledge (<xref ref-type="bibr" rid="B72">Peng, 2013</xref>) and job satisfaction survey (<xref ref-type="bibr" rid="B84">Spector, 1985</xref>). There were negative correlations (e.g., individual barriers and intrinsic intent to learn, &#x03B2; = &#x2212;0.19), and positive ones with hiding knowledge; for example, the individual components of both formal (0.282) and informal barriers to learning (0.279). Referring to <xref ref-type="bibr" rid="B4">Amora (2021)</xref> the cut-off point is at 0.50. This is not an uncommon situation when testing a new instrument with no comparable measurements on hands. To face this situation an AVE has been calculated using SPSS 27 and Excel. The scores showed acceptable values as previously indicated (<xref ref-type="bibr" rid="B42">Kalkbrenner, 2021</xref>).</p>

<sec id="S5" sec-type="discussion">
<title>Discussion</title>
<p>The purpose of this study was to develop and validate a measurement instrument of barriers to informal and formal learning at the workplace. Based on the results of the pre-study (Author, under review) and existing instruments (<xref ref-type="bibr" rid="B8">Belling et al., 2004</xref>; <xref ref-type="bibr" rid="B19">Crouse et al., 2011</xref>), an instrument that measures barriers to both informal and formal learning was developed.</p>
<p>The scale was validated through a cross-sectional questionnaire with 112 consultancy employees and freelancers. The results lead to the development of instrument formed of five factors; three-factor scale measuring barriers to formal learning and a two-factor scale measuring barriers to informal learning. The five factors are: individual barriers (15 items on motivation or fears), organizational/structural barriers (21 items on hierarchy, team climate, and leadership), technical barriers (5 items on technical conditions), change (4 items on turnover intention) and uncertainty (5 items on career options). The Cronbach&#x2019;s alpha values for all factors ranged between 0.80 and 0.86.</p>
<sec id="S5.SS1">
<title>General reflection on the study</title>
<p>As stated, the steps undertaken rely on <xref ref-type="bibr" rid="B35">Hinkin&#x2019;s (1998)</xref> framework for scale validation and are in line with <xref ref-type="bibr" rid="B63">Moosbrugger and Schermelleh-Engel (2012)</xref>. Firstly, the results of the exploratory factor analysis (EFA; oblique rotation), were used to reduce the number of items significantly. By using EFA the multiple manifest variables, here items of the questionnaire on barriers to learning can be used to draw conclusions about underlying latent variables and factors. As concluded by <xref ref-type="bibr" rid="B67">Nguyen and Waller (2022)</xref> an EFA leads to a reduction of variables to a few underlying factors of the manifest variables. This meant reducing the number of items from 89 items and 10 factors to 44 items and five factors.</p>
<p>Secondly, an internal consistency assessment (Cronbach&#x2019;s alpha and McDonald&#x2019;s omega), has been carried out. This assessment refers to the precision or accuracy of a measurement (<xref ref-type="bibr" rid="B55">Marcial and Launer, 2021</xref>). This indirectly addresses two points. The reliability as the measurement accuracy of a scale without regard to the content, and a reliability as the determination of the measurement error with which the individual values are afflicted, without regard to whether the scale also measures what it purports to measure (validity). With Cronbach&#x2019;s alpha results for all scales from 0.80 to 0.86 the overall accuracy of the measurement can be regarded as satisfying (<xref ref-type="bibr" rid="B88">Warrens, 2016</xref>).</p>
<p>Thirdly a CFA was conducted. Keeping in mind that here the CFA was used to test the structure and functioning of the barriers to learning measurement instrument. The fit indices of the measurement model show a more than acceptable fit, for barriers to formal learning as well as to informal learning (<xref ref-type="bibr" rid="B14">Brown and Moore, 2012</xref>).</p>
<p>Fourthly convergent validity assessment was carried out. This testing reveals weather a scale shows correlations with comparable scales or instruments (<xref ref-type="bibr" rid="B16">Cheah et al., 2018</xref>). For this newly designed instrument the IWC (<xref ref-type="bibr" rid="B21">Decius et al., 2019</xref>), hiding knowledge (<xref ref-type="bibr" rid="B72">Peng, 2013</xref>) were used successfully. Going in line with <xref ref-type="bibr" rid="B60">Messick (1995)</xref>, the validation process is not a static procedure. After successfully developing and testing a new instrument, the next consequent step is the actual implementation of the instrument in research. Followed by adequate interpretation of the results from it.</p>
</sec>
<sec id="S5.SS2">
<title>Limitations of the study</title>
<p>According to <xref ref-type="bibr" rid="B52">Lambriex-Schmitz et al. (2020)</xref> every validation study &#x201C;has several limitations that should be addressed in future research and questionnaire validity testing&#x201D; (<xref ref-type="bibr" rid="B52">Lambriex-Schmitz et al., 2020</xref>, p. 334). Since the instrument is based on an explorative interview study (<xref ref-type="bibr" rid="B100">Anselmann, in press</xref>) and can be seen as an innovative measurement instrument, completely comparable instruments are not available. This could be seen as a limitation to the instrument&#x2019;s convergent validity, so the instrument will be used in a follow-up study in which its validity is analyzed. Furthermore, the instrument was tested in the consultancy domain. However, it is not limited to this field, it should therefore be applied in other fields with knowledge-intensive service works (<xref ref-type="bibr" rid="B47">Korster, 2022</xref>) or even domains in the blue-collar sector (<xref ref-type="bibr" rid="B22">Decius et al., 2021</xref>).</p>
<p>Another limitation of this work can be seen by the small sample size of 112 participants from the domain of consultancy. The problem with a sample size that is regarded as small is a lack of statistical power. Although <xref ref-type="bibr" rid="B64">Muth&#x00E9;n and Muth&#x00E9;n (2017)</xref> would recommend a sample size from at least 150, for confirmatory factor analyses or EFA, this threshold is much bound on the quality of the data. With small samples, estimation problems are more likely to occur in CFA or EFA and estimation problems occur more frequently. But this likeness is strongly bound to missing values, a lack of power, as well as on scales with low numbers regarding the consistency assessment, e.g., values of Cronbach&#x2019;s alpha below 0.70 (<xref ref-type="bibr" rid="B51">Kyriazos, 2018b</xref>). Within this instrument for measuring barriers to learning none of these weaknesses apply. In the used sample for the validation there are no missing values. Only complete samples have been used for the development. There are no estimated values within the whole dataset. The Cronbach&#x2019;s alpha results are consistent at a level at 0.80 or higher. These values are interpreted as good to satisfying, according to <xref ref-type="bibr" rid="B88">Warrens (2016)</xref>. In addition <xref ref-type="bibr" rid="B56">Marsh et al. (1998)</xref> related factor sizes and sample sizes. Showing that more items per factor more often lead to reliable results. Predicting more accurate and more stable parameter estimation, and fewer less non-convergent solutions and more reliable factors. Other they propose a sample size larger than 100 to run CFA or EFA correctly. Although, 112 participants in a validation study seems not high (<xref ref-type="bibr" rid="B17">Cohen et al., 2018</xref>) the conducted measurements all indicated more than satisfying values. The statistical power and the significance could be proven.</p>
<p>The nature of an explorative study itself can also be a limitation, but given the fact that there are always upcoming fields of research, an explorative study like this can provide the very first insight into unexplored concepts and highlight paths for new research with the goal of obtaining insights into barriers to learning in the workplace. Further studies can thus determine any patterns regarding characteristics and barriers in informal workplaces specifically.</p>
</sec>
<sec id="S5.SS3">
<title>Implication of the study</title>
<p>As claimed by <xref ref-type="bibr" rid="B10">Billett (2022)</xref> and <xref ref-type="bibr" rid="B32">Harteis (2022)</xref> research on workplace learning needs to be more innovative and therefore has to explore more, so far unconventional aspects of learning at the workplace. This research-based measurement combines barriers to learning on various levels and hierarchies. This includes barriers related to resource constraints, structural, cultural or organizational constraints, insufficient access, individual components, as well as team or interpersonal constraints, furthermore hierarchical relationships, barriers to learning rooting in unclear career perspectives, organizational changes, and finally technical limitations. This broad range of detecting barriers to leaning are summarized in five factors: individual barriers (15 items on motivation or fears), organizational/structural barriers (21 items on hierarchy, team climate and leadership), technical barriers (5 items on technical conditions), change (4 items on turnover intention) and uncertainty (5 items on career options). Referring on individual, team and organizational level.</p>
<p>This is a unique approach to tackle the highly complex system of barriers to learning within the workplace. However, further research has yet to shed more light on the complex relationship between learning barriers and learning activities. It can be assumed that learning barriers at different levels have different influences on various learning activities, rendering it very important to get a closer look at these relations, especially because individuals prefer different learning scenarios at the workplace. This emphasis shows that barriers to learning form a continuum based on individual learning experiences, situations and roles. So, to better understand learning activities, it is necessary to reflect on facilitators and barriers equally. Therefore, this validated instrument will be used for further studies on barriers to learning at the workplace. It will be deployed to identify the holistic concept of barriers to learning at the workplace, within individual, team and organizational level. In addition, this measurement is used to identify the role multiple additional factors like formal and informal learning activities (<xref ref-type="bibr" rid="B12">Brion, 2021</xref>), toxic leadership (<xref ref-type="bibr" rid="B77">Schmidt, 2008</xref>), competitive work environment (<xref ref-type="bibr" rid="B28">Fletcher and Nusbaum, 2010</xref>), and the degree of digitalization of the workplace (<xref ref-type="bibr" rid="B30">G&#x00F6;rs et al., 2019</xref>).</p>
</sec>
<sec id="S5.SS4">
<title>Practical value of the study</title>
<p>This measurement instrument is appropriate to determine what hinders individuals from learning in their organizations. In line with <xref ref-type="bibr" rid="B23">Dolata et al. (2021)</xref> The field of consultancy is a challenging work environment with highly complex tasks (<xref ref-type="bibr" rid="B69">O&#x2019;Leary, 2020</xref>) and with a constant need for professional development. While studies often focus on the diverse facilitating factors for learning (<xref ref-type="bibr" rid="B39">Jeong et al., 2018</xref>), less is known about how to determine what hinders individuals from learning at the workplace. Therefore, this instrument can be used in research as well as organizations to find out what hinders employees&#x2019; learning. It leads to the question of what is not working well and should be changed, like miscommunication, poor work environment and lack of autonomy (<xref ref-type="bibr" rid="B12">Brion, 2021</xref>; <xref ref-type="bibr" rid="B22">Decius et al., 2021</xref>; <xref ref-type="bibr" rid="B46">Kim et al., 2021</xref>). This instrument also features the most relevant factors that can be barriers to learning on all levels (e.g., leadership on the organizational level, team climate on the team level and fear on the individual level). It can therefore serve as even the starting point for justified and established steps in organizational development.</p>
<p>This validation study, as well as the following main study (<xref ref-type="bibr" rid="B5">Anselmann, in prep.</xref>) highlights the very importance of identifying, reflecting and tackling barriers to learning at the workplace. Apart from the academic discourse in journals and conference presentations, this theme is distributed in more practical terms to the professionals in the field. Therefore, three major steps have been initiated. Firstly, HR professionals and companies that took part in the interview study (<xref ref-type="bibr" rid="B100">Anselmann, in press</xref>), have been updated and informed throughout the process about barriers to learning and first implications. Small workshops and feedback loops have been carried out. Secondly, all the participants of the online questionnaires, the validation of the measurement (<italic>N</italic> = 112) and the main study on barriers to learning (<italic>N</italic> = 230) could sign up for a newsletter, providing them with regular information on barriers to learning at the workplace and practical implication. Thirdly, an online workshop is scheduled to bridge academic and research driven approaches with daily work situation in companies. This workshop will contain short but significant inputs on barriers to learning, cases and best practices from companies, presented by HR managers and other researchers, and finally working groups for raising attention to identifying, reflecting and tackling barriers to learning at the workplace.</p>
