  • The Psychometric Properties of the Psychological Work Immersion Scale: An ESEM vs ICM-CFA Approach
    Llewellyn E. van Zyl and Dieter Veldsman

    Springer Science and Business Media LLC
    AbstractThis study investigates the psychometric properties and measurement invariance of the Psychological Work Immersion Scale (PWIS) scale within global organisational contexts. Data were gathered from 19134 working adults in the US, the UK, the Middle East, Africa, and Australia. To determine the best-fitting factorial model, a series of traditional ICM-CFA and less restrictive ESEM models were estimated and systematically compared. The results showed that a bifactor ESEM model, with one general factor of overall psychological work immersion and nine specific factors (strategic connection, manager credibility, appreciative feedback, enabling environment, team relations, strength use, employee voice, recognition and rewards, personal development) fitted the data best, was reliable and showed strong measurement invariance across genders and levels of education. The results show that psychological work immersion is a multidimensional construct that is both a function of yet separate from a dynamic interaction between the nine performance-enhancing conditions or enablers. Therefore, The PWIS can be used to measure psychological work immersion validly and reliably and could be used to make meaningful latent mean comparisons between genders and different levels of education.

    Academic task performance (TP) refers to the proficiency with which students perform in academic tasks through making the right choices and completing core tasks central to their academic studies, on time and to specification. We adapted Koopmans et al.’s task performance scale (TPS) for use within tertiary education and investigated its psychometric properties, internal consistency and measurement invariance across age, gender and national groups in university students (n = 3,265). The results showed that a hierarchical ESEM model with one higher-order task performance factor consisting of time management and task efficiency fitted the data best. The TPS exhibited full measurement invariance across gender and age groups, implying that the latent mean scores can be used to determine differences. However, invariance could only partially be established for national cohorts, implying that cross-national comparisons may not be possible. These findings offer preliminary support for the TPS as a valid instrument for gauging students’ academic task performance.

  • Gratitude in the Time of the Coronavirus: A Thematic Analysis of the Three Good Things in Young Adults
    Zelda Di Blasi, Megan O’Doherty, and Llewellyn E. van Zyl

    Springer Science and Business Media LLC
    AbstractThe COVID-19 pandemic has significantly disrupted the daily lives of college students, resulting in elevated levels of stress, anxiety, and isolation. Research suggests positive psychology interventions aimed at practicing gratitude, offer potential benefits in reducing these common mental health problems. However, there is a limited understanding of how or why these interventions work nor what function gratitude plays in the lives of young adults during the COVID-19 pandemic. As such, the purpose of the paper was to explore the sources and targets of gratitude of college students during the COVID-10 lockdown in Ireland. This study aimed analyse the content of the ‘Three Good Things’ intervention as reported by young adults during the COVID-19 lockdowns in Ireland. A total of 109 college students participated in a 7-day online ‘Three Good Things’ intervention, where they were prompted to reflect on and document three positive experiences each day. Participants were asked to elaborate on how these experiences made them feel and to highlight their role in facilitating these positive experiences. Thematic analysis was used to analyze the 2,200 submitted responses. The findings revealed three overarching themes relating to participants’ expressions of gratitude during the COVID-19 lockdown: (1) cultivating positive social interactions, (2) prioritizing meaningful self-care, and (3) fostering hope for a more normal life post-pandemic. By delving into the lived experiences of college students, this study sheds light on the elements central to their expressions of gratitude during the COVID-19 pandemic. The findings underscore the importance of social connections, self-care practices, and hopeful prospects as sources of gratitude among students.

  • Person-environment fit and task performance: exploring the role(s) of grit as a personal resource
    Llewellyn E. van Zyl, H. A. van Vuuren, Lara C. Roll, and Marius W. Stander

    Springer Science and Business Media LLC
    Abstract The Job Demands-Resources Framework (JDR) has established job- and personal resources as essential elements motivating people to perform. Whilst the purpose of job resources in this motivational process is well established, the role of personal resources is still quite ambiguous. Within the JDR framework, personal resources could (a) directly affect performance, (b) indirectly affect the relationship between a job resource and a performance outcome and (c) moderate the job resource-performance relationship. Grit has recently emerged as a promising personal resource as it could potentially act as a direct antecedent-, mediator and moderator within the motivational process of the JDR. To further the debate on the role of personal resources, this paper explores the function of grit (as a personal resource) within the person-environment fit (job resource) and task performance relationship. Specifically, the aim is to determine if grit directly or indirectly affects the relationship between person-environment fit and task performance. Finally, it aims to investigate whether grit moderates this relationship. Data were collected from 310 working adults through electronic surveys, and the relationships were explored through structural equation modelling. When controlling for age and gender, the results showed a positive association between person-environment fit, grit and task performance. Further, grit was also found to indirectly affect the relationship between the person-environment fit and task performance. However, no moderating effect could be established. This signifies the importance of grit as a psychological process, rather than a buffering element that may explain how person-environment fit affects performance outcomes.

  • The Holistic Life-Crafting Model: a systematic literature review of meaning-making behaviors
    Llewellyn E. van Zyl, Noah C. M. Custers, Bryan J. Dik, Leoni van der Vaart, and Jeff Klibert

    Frontiers Media SA
    Pursuing meaningful life experiences is vital for wellbeing and health. Crafting strategies, such as job crafting and work-life balance crafting, have been developed to create meaning in specific life domains. However, these strategies share common underlying behaviors that transcend specific contexts. Building on this understanding, we propose a comprehensive “holistic life-crafting” approach that integrates overlapping behaviors from various crafting strategies. This study aims to clarify the theoretical conceptualization of life-crafting by identifying common strategies and behaviors underlying different meaning-making crafting approaches. Through a systematic literature search of six databases between January and April 2022, we identified 16,479 published records. Using predefined inclusion–exclusion criteria, 51 records (reflecting five crafting approaches, resulting in 223 different crafting behaviors) remained. Through content analysis, we grouped these behaviors into seven broader crafting strategies, forming the “holistic life-crafting” approach. Findings suggest that life-crafting is a holistic, continuous process of proactive meaning-making by intentionally balancing life demands with available resources and altering life’s cognitive, environmental, interest, relational, skill, and task-related aspects to promote personal growth and wellbeing. The holistic approach encompasses cognitive, environmental, interest, relational, resources-demands, skill, and task crafting strategies. This framework provides a comprehensive understanding of how individuals can actively shape their lives to promote more meaningful life experiences across different domains.Systematic review registrationPROSPERO, identifier CRD42022333930.

  • The Poverty-Related Stress Scale: Development and Validation of a Multidimensional Measure Assessing Poverty-Related Stressors
    Brianna Allen, Jeffrey Klibert, and Llewellyn E. van Zyl

    Hindawi Limited
    Background. Poverty-related stress plays a pivotal role in mediating the impact of poverty on behavioral health outcomes. However, existing research on adult poverty-related stress suffers from limited scope and inadequate measurement approaches. To address these shortcomings, our study undertakes a comprehensive investigation to develop and validate a multidimensional Poverty-Related Stress Scale (PRSS). Methods. A multistudy research design was employed to develop and validate the PRSS. Study 1 ( N = 206 ) established a multidimensional framework for poverty-related stress by exploring the factor structure and internal consistency of our measure. Study 2 ( N = 400 ) evaluated nuanced psychometric properties, including factorial validity, internal consistency, and temporal invariance, using confirmatory factor analyses (CFA) and modern exploratory structural equation models (ESEM). Lastly, Study 3 ( N = 470 / 219 ) examined the criterion validity of our scale by investigating its concurrent and predictive relationships with depression, anxiety, and flourishing. Results. The findings consistently supported a hierarchal ESEM model for overall poverty-related stress, reflecting the dynamic interaction among three stressors: noise disturbance, housing dysfunction, and financial distress. This model exhibited temporal invariance, with different studies reliably measuring distinct components of poverty-related stress. Concurrent validity was demonstrated by significant associations between overall poverty-related stress and theoretically relevant constructs, such as depression, anxiety, and flourishing, at different time points. Additionally, predictive validity was established, showing poverty-related stress measured at time 1 accounted for variations in depression, anxiety, and flourishing at time 2. The results provide robust evidence for the validity and reliability of the PRSS as a tool for measuring poverty-related stress and its underlying factors. Conclusions. Our findings offer compelling preliminary support for the utility of our measure. Further research and potential clinical applications are discussed to deepen the understanding of poverty-related stress and its implications for behavioral health outcomes.

    Wiley
    Research indicates that university students present higher levels of psychological distress compared with non-student age-matched youth. These levels are higher among healthcare students, and even higher during the Covid-19 pandemic. Therefore, cost-effective large-scale interventions are needed in order to prevent further development of psychological distress during this period, and more generally. The aim of the current study was to assess the effectiveness of an 8-week Internet-based positive psychology intervention for healthcare students in Tunisia. A two-armed randomized controlled trial was conducted among a sample of 366 health care students (183 in the experimental group and 183 in the control group), with a majority of women (94%). The average age was 20.74 years (±1.64). The participants completed the following online questionnaires at three time-points (before the program, immediately after, and three months later): stress, anxiety, depression, emotional regulation, optimism, hope, study engagement, and well-being. Repeated-measures ANOVAs revealed significant positive effects of the intervention on all the measured variables for the experimental group. The results showed a significant improvement immediately after the intervention compared to the control group, which was maintained three months later. This program may thus be considered as a promising means of improving students' mental health and study engagement.

    AbstractDespite its popularity in practice, the Grit-O Scale has shown inconsistent factorial structures and differing levels of internal consistency in samples outside the USA. The validity of the Grit-O Scale in different contexts is, therefore, questionable. As such, the purpose of this paper was to determine whether the Grit-O Scale could be used as a valid and reliable measure to compare grit across different nations. Specifically, the aim was to investigate the factorial validity, reliability, and concurrent validity of the Grit-O Scale and to investigate measurement invariance across three national cohorts (Europe, the USA, and Hong Kong). Data were gathered from 1888 respondents stemming from one USA- (n = 471), two Hong Kong- (n = 361) and four European (n = 1056) universities. A series of traditional CFA and less restrictive ESEM models were estimated and systematically compared to determine the best factorial form of the Grit-O Scale. The results showed that a bifactor ESEM model, with one general factor of overall grit and two specific factors (consistency of interest and perseverance of effort), fitted the data best, showed strong measurement invariance across the three samples, and showed itself to be a reliable measure. Furthermore, concurrent validity was established by showing that the three grit factors were directly and positively related to task performance. Meaningful latent comparisons between the three cultural cohorts could therefore be made. The results imply that cross-national comparisons of grit may only be problematic when traditional CFA approaches are favoured. In contrast, ESEM modelling approaches may compensate for cross-national differences in understanding grit and control for differences in the interpretation of the scale’s items. Therefore, the bifactor ESEM approach may be more appropriate for cross-cultural and cross-national comparison studies, as it allows for these differences to be meaningfully captured, modelled, and controlled for.

  • The General Academic Self-Efficacy Scale: Psychometric Properties, Longitudinal Invariance, and Criterion Validity
    Llewellyn E. van Zyl, Jeff Klibert, Rebecca Shankland, Eric W. K. See-To, and Sebastiaan Rothmann

    SAGE Publications
    Academic self-efficacy (ASE) refers to a student’s global belief in his/her ability to master the various academic challenges at university and is an essential antecedent of wellbeing and performance. The five-item General Academic Self-Efficacy Scale (GASE) showed promise as a short and concise measure for overall ASE. However, of its validity and reliability outside of Scandinavia is limited. Therefore, this paper aimed to investigate the psychometric properties, longitudinal invariance, and criterion validity of the GASE within a sample of university students (Time 1: n = 1056 & Time 2: n = 592) in the USA and Western Europe. The results showed that a unidimensional factorial model of overall ASE fitted the data well was reliable and invariant across time. Further, criterion validity was established by finding a positive relationship with task performance at different time stamps. Therefore, the GASE can be used as a valid and reliable measure for general ASE.

    ObjectivesTo investigate whether citizens’ adherence to health-protective non-pharmaceutical interventions (NPIs) during the COVID-19 pandemic is predicted by identity leadership, wherein leaders are perceived to create a sense of shared national identity.DesignObservational two-wave study. Hypotheses testing was conducted with structural equation modelling.SettingData collection during the COVID-19 pandemic in China, Germany, Israel and the USA in April/May 2020 and four weeks later.ParticipantsAdults in China (n=548, 66.6% women), Germany (n=182, 78% women), Israel (n=198, 51.0% women) and the USA (n=108, 58.3% women).MeasuresIdentity leadership (assessed by the four-item Identity Leadership Inventory Short-Form) at Time 1, perceived shared national identification (PSNI; assessed with four items) and adherence to health-protective NPIs (assessed with 10 items that describe different health-protective interventions; for example, wearing face masks) at Time 2.ResultsIdentity leadership was positively associated with PSNI (95% CI 0.11 to 0.30, p<0.001) in all countries. This, in turn, was related to more adherence to health-protective NPIs in all countries (95% CI 0.03 to 0.36, 0.001≤p≤0.017) except Israel (95% CI −0.03 to 0.27, p=0.119). In Germany, the more people saw Chancellor Merkel as engaging in identity leadership, the more they adhered to health-protective NPIs (95% CI 0.04 to 0.18, p=0.002). In the USA, in contrast, the more people perceived President Trump as engaging in identity leadership, the less they adhered to health-protective NPIs (95% CI −0.17 to −0.04, p=0.002).ConclusionsNational leaders can make a difference by promoting a sense of shared identity among their citizens because people are more inclined to follow health-protective NPIs to the extent that they feel part of a united ‘us’. However, the content of identity leadership (perceptions of what it means to be a nation’s citizen) is essential, because this can also encourage people to disregard such recommendations.

  • The Life Crafting Scale: Development and Validation of a Multi-Dimensional Meaning-Making Measure
    Shi Chen, Leander van der Meij, Llewellyn E. van Zyl, and Evangelia Demerouti

    Frontiers Media SA
    Finding meaning in our lives is a central tenet to the human experience and a core contributor to mental health. Individuals tend to actively seek the sources of meaning in their lives or consciously enact efforts to create or “craft” meaning in different life domains. These overall “Life Crafting” behaviors refer to the conscious efforts individuals exert to create meaning in their lives through (a) cognitively (re-)framing how they view life, (b) seeking social support systems to manage life challenges, and (c) actively seeking challenges to facilitate personal growth. Specifically, these behaviors are actioned to better align life goals, personal needs, values, and capabilities. However, no psychological assessment instrument currently exists to measure overall life crafting. As such, the purpose of this paper was twofold: to conceptualize life crafting and to develop, validate and evaluate a robust measure of overall life crafting. A mixed-method, multi-study research design was employed. First, nine participants were interviewed to determine the methods or techniques used to craft meaningful life experiences. These methods/techniques were used as indicators to create an initial item pool which was then reviewed by a panel of experts to ensure face validity. Second, in Study 1, the factorial structure of the instrument was explored by gathering data from a convenience sample (N = 331), with the results showing support for a three-factor structure of life crafting, consisting of (a) cognitive crafting, (b) seeking social support, and (c) seeking challenges. Finally, in Study 2 (N = 362), the aim was to confirm the factorial structure of the Life Crafting scale and to determine its level of internal consistency, partial measurement invariance across genders, and criterion validity [meaning in life (β = 0.91), mental health (β = 0.91), work engagement (β = 0.54), and job burnout (β = −0.42)]. The results supported a second-order factorial model of Life Crafting, which comprised of three first-order factors (cognitive crafting, seeking social support, and seeking challenges). Therefore, the Life Crafting Scale can be used as a valid and reliable instrument to measure- and track the effectiveness of life crafting interventions.

  • Mental Health during COVID-19 Pandemic: The Role of Optimism and Emotional Regulation

    MDPI AG
    In light of different challenges associated with the COVID-19 pandemic, university students are considered a particularly vulnerable population to mental health and study engagement issues. The first years at university represent a crucial period for students and are associated with an increase in mental health problems, particularly in healthcare studies. This study aimed (1) to document the current levels of mental health and study engagement among healthcare students in Tunisia, and (2) to investigate the relationships between emotional regulation, optimism, study engagement and common mental health problems (stress, anxiety and depression) among this population. A cross-sectional, electronic survey-based research design was used to draw a sample of 366 health care students from a University in Tunisia. Participants mostly reported mild (34.7%) or moderate (44.3%) levels of depression, moderate (44.7%) or severe (33.6%) levels of anxiety, average (50.8%) or mild (33.8%) levels of stress, and high levels of study engagement (>85%). Through structural equation modelling, the results showed that emotional regulation negatively affected stress, anxiety, and depression. Optimism partially mediated the relationship between emotional regulation, anxiety and depression and fully mediated the relationship between emotional regulation and study engagement. The findings indicated a high prevalence of psychological distress among healthcare university students in Tunisia, and specific protective factors that may be targeted to reduce mental health problems.

  • PERMA+4: A Framework for Work-Related Wellbeing, Performance and Positive Organizational Psychology 2.0
    Stewart I. Donaldson, Llewellyn Ellardus van Zyl, and Scott I. Donaldson

    Frontiers Media SA
    A growing body of empirical evidence suggests that positive emotions, engagement, relationships, meaning, and accomplishments (PERMA) may be a robust framework for the measurement, management and development of wellbeing. While the original PERMA framework made great headway in the past decade, its empirical and theoretical limitations were recently identified and critiqued. In response, Seligman clarified the value of PERMA as a framework for and not a theory of wellbeing and called for further research to expand the construct. To expand the framework into organizational contexts, recent meta-analyses and systematic literature reviews showed that physical health, mindset, physical work environments and economic security could be seen as essential contextually relevant building blocks for work-related wellbeing and are therefore prime candidates to expand the PERMA framework for use within organizational contexts. Through expanding the original PERMA framework with these four factors, a new holistic approach to work-related wellbeing and work performance was born: the PERMA+4. As such, the purpose of this brief perspective paper is to provide a conceptual overview of PERMA+4 as holistic framework for work-related wellbeing and work performance which extends beyond the predominant componential thinking of the discipline. Specifically, we aim to do so by providing: (1) a brief historical overview of the development of PERMA as a theory for wellbeing, (2) a conceptual overview of PERMA+4 as a holistic framework for work-related wellbeing and work performance, (3) empirical evidence supporting the usefulness of PERMA+4, and (4) charting a course for the second wave of positive organizational psychological research.

  • Exploratory Structural Equation Modeling: Practical Guidelines and Tutorial With a Convenient Online Tool for Mplus
    Llewellyn E. van Zyl and Peter M. ten Klooster

    Frontiers Media SA
    Critics of positive psychology have questioned the validity of positive psychological assessment measures (PPAMs), which negatively affects the credibility and public perception of the discipline. Psychometric evaluations of PPAMs have shown that various instruments produce inconsistent factor structures between groups/contexts/times frames, that their predictive validity is questionable, and that popular PPAMs are culturally biased. Further, it would seem positive psychological researchers prioritize date-model-fit over measurement quality. To address these analytical challenges, more innovative and robust approaches toward the validation and evaluation of PPAMs are required to enhance the discipline's credibility and to advance positive psychological science. Exploratory Structural Equation Modeling (ESEM) has recently emerged as a promising alternative to overcome some of these challenges by incorporating the best elements from exploratory- and confirmatory factor analyses. ESEM is still a relatively novel approach, and estimating these models in statistical software packages can be complex and tedious. Therefore, the purpose of this paper is to provide novice researchers with a practical tutorial on how to estimate ESEM with a convenient online tool for Mplus. Specifically, we aim to demonstrate the use of ESEM through an illustrative example by using a popular positive psychological instrument: the Mental Health Continuum-SF. By using the MHC-SF as an example, we aim to provide (a) a brief overview of ESEM (and different ESEM models/approaches), (b) guidelines for novice researchers on how to estimate, compare, report, and interpret ESEM, and (c) a step-by-step tutorial on how to run ESEM analyses in Mplus with the De Beer and Van Zy ESEM syntax generator. The results of this study highlight the value of ESEM, over and above that of traditional confirmatory factor analytical approaches. The results also have practical implications for measuring mental health with the MHC-SF, illustrating that a bifactor ESEM Model fits the data significantly better than any other theoretical model.

  • The Work Gratitude Scale: Development and Evaluation of a Multidimensional Measure
    Carolyn M. Youssef-Morgan, Llewellyn E. van Zyl, and Barbara L. Ahrens

    Frontiers Media SA
    This study explores gratitude as a multidimensional and work-specific construct. Utilizing a sample of 625 employees from a variety of positions in a medium-sized school district in the United States, we developed and evaluated a new measure, namely the Work Gratitude Scale (WGS), which encompasses recognized conative (intentional), cognitive, affective, and social aspects of gratitude. A systematic, six-phased approach through structural equation modeling (SEM) was used to explore and confirm the factorial structure, internal consistency, measurement invariance, concurrent, convergent, and discriminant validity of the WGS. The results supported a 10-item measure with three dimensions: “grateful appraisals” (three items), “gratitude toward others” (four items), and “intentional attitude of gratitude” (three items). Thereafter, first-order, second-order, and bifactor confirmatory models were estimated and compared. Work gratitude was found to be best described by a second-order construct with three underlying first-order dimensions. Measurement invariance was supported in relation to gender. Concurrent validity was supported in relation to two existing dispositional gratitude scales, namely the Gratitude Questionnaire and the Gratitude, Resentment, and Appreciation Scale (GRAT). Convergent validity was supported in relation to the Core Self-Evaluations Scale (CSES) and the Psychological Capital Questionnaire. Discriminant validity was supported in relation to various demographic factors such as age, gender, occupation, and tenure. The findings support the WGS as a multidimensional measure that can be used in practice to measure overall work-related gratitude and to track the effectiveness of gratitude-related workplace interventions.

  • Perceptions of the Targets and Sources of COVID-19 Threat are Structured by Group Memberships and Responses are Influenced by Identification with Humankind

    The purpose of this study was to investigate which social groups are perceived as a threat target and which are perceived as a threat source during the COVID-19 outbreak. In a German sample (N = 1454) we examined perceptions of social groups ranging from those that are psychologically close and smaller (family, friends, neighbors) to those that are more distal and larger (people living in Germany, humankind). We hypothesized that psychologically closer groups would be perceived as less affected by COVID-19 as well as less threatening than more psychologically distal groups. Based on social identity theorizing, we also hypothesized that stronger identification with humankind would change these patterns. Furthermore, we explored how these threat perceptions relate to adherence to COVID-19 health guidelines. In line with our hypotheses, latent random-slope modelling revealed that psychologically distal and larger groups were perceived as more affected by COVID-19 and as more threatening than psychologically closer and smaller groups. Including identification with humankind as a predictor into the threat target model resulted in a steeper increase in threat target perception patterns, whereas identification with humankind did not predict differences in threat source perceptions. Additionally, an increase in threat source perceptions across social groups was associated with more adherence to health guidelines, whereas an increase in threat target perceptions was not. We fully replicated these findings in a subgroup from the original sample (N = 989) four weeks later. We argue that societal recovery from this and other crises will be supported by an inclusive approach informed by a sense of our common identity as human beings.
