Аннотация:The satisfaction of the basic psychological needs for autonomy, competence, and relatedness, as defined in Self‐Determination Theory, has been identified as an important predictor of individuals' optimal functioning in various life domains. The study of work‐related need satisfaction seems, however, hampered by the lack of a validated measure. To assist future research, the present study aimed to develop and validate a Work‐related Basic Need Satisfaction scale (W‐BNS). Using four Dutch‐speaking samples, evidence was found for the three‐factor structure of the scale, the discriminant validity, and the reliability of the three need satisfaction subscales as well as their criterion‐related and predictive validity. The W‐BNS may therefore be considered as a promising tool for future research and practice.
