To this end, university students’ self-efficacy beliefs, their academic engagement and time management skills were focused. 304 university students from various departments participated in the research. Results showed that the relationship between self-efficacy and GPA was fully mediated by academic engagement. Moreover, time management moderated self-efficacy – academic engagement relationship. The moderated mediation hypothesis was also supported; the mediated relationship between self-efficacy, academic engagement and GPA was significant only at the high levels of time management. The contribution of these findings to our understanding of factors related to GPA and their interactive effects was discussed.

A curvilinear relationship between value congruence regarding opportunities for personal development and work engagement was hypothesized, building on the job demands-resources , mediation of burnout and engagement, and attraction-selection-attrition models. It was also hypothesized that organizational tenure would moderate the curvilinear relationship between value congruence and work engagement. Data were collected from 204 white-collar employees. Both difference score-based polynomial regression analysis and response surface analysis results provided support for the curvilinear value congruence-work engagement relationship. Moreover, as expected, organizational tenure moderated this relationship: The effect of value congruence on work engagement was stronger for employees with shorter tenure compared to those with longer tenure. Findings not only highlight the importance of value congruence regarding opportunities for personal development in work engagement, but also the role of tenure in this relationship.

The aim of this research is to evaluate the psychometric properties of the Turkish form of the Implicit Positive and Negative Affect Test (IPANAT-TR), originally developed by Quirin et al. (2009a) to measure affect indirectly. Method: The study data comprised of psychology and sociology students from Ege University, and full-time and part-time employees from public and private organizations in İzmir. A pilot study was carried out with a group of 57 undergraduate students in order to select the artificial words to be used in the scale. Subsequently the scale was sent to a total of 938 participants, comprising 569 students and 369 employees. Test-retest reliability was assessed with 46 participants after a one-week interval and with 55 participants after a four-week interval. Results: The principal components analysis showed a clear two-factor structure for the IPANAT-TR. The internal consistency scores were 0.92 for Implicit Positive Affect (IPA) and 0.85 for Implicit Negative Affect (INA). The one-week and four-week test retest reliability estimates varied between 0.51 and 0.75. The construct validity assessments showed that the expected relationships between the IPANAT-TR and tested constructs were mostly confirmed. The results of measurement invariance analysis showed that the IPANAT-TR has full measurement invariance across employee and student samples. Conclusion: The results of the reliability, validity and measurement invariance analyses carried out in the current study demonstrated that the IPANAT-TR is a reliable and valid measurement instrument to assess implicit affect.
