یک معادله ساختاری اکتشافی بیفاکور، مدلسازی ساختار نیازهای روانشناختی اولیه در مقیاس کار

This study investigates the structure of employees' ratings of the satisfaction of their basic psychological needs for autonomy, competence, and relatedness at work using the newly developed bifactor exploratory structural equation modeling (ESEM) framework. Using a sample of 366 exercise professionals who completed the new Portuguese version of the Basic Psychological Needs at Work Scale (BPNWS: Brien et al., 2012), the results demonstrated the superiority of a Bifactor-ESEM representation of BPNWS ratings when compared to alternative representations of the data (first-order and bifactor confirmatory factor analyses, and first-order ESEM). The results also supported the composite reliability, measurement invariance across gender, and nomological validity (in relations to measures of psychological wellbeing and distress at work) of BPNWS ratings. Importantly, these results demonstrated the importance of relying on measurement models providing a way to achieve a proper disaggregation of employees' global levels of need satisfaction relative to the satisfaction of their more specific needs for autonomy, competence, and relatedness.
