This paper reviews the literature on basic psychological need satisfaction at work, focusing on three specific aims: testing the unique predictive validity of each basic psychological need, evaluating the appropriateness of using an overall need satisfaction measure, and examining the influence of the scale used to assess basic psychological needs. The review is based on a meta-analysis of 99 studies with 119 distinct samples, examining the antecedents and consequences of basic need satisfaction. The results generally support the unique predictive validity of each basic psychological need (autonomy, competence, and relatedness) for psychological growth, internalization, and well-being. However, the variance explained by these needs is often statistically significant but practically insignificant. The review also highlights issues with the commonly used scales and suggests future research directions, including the study of need frustration, cultural differences, and integrating basic needs with other motivation theories.This paper reviews the literature on basic psychological need satisfaction at work, focusing on three specific aims: testing the unique predictive validity of each basic psychological need, evaluating the appropriateness of using an overall need satisfaction measure, and examining the influence of the scale used to assess basic psychological needs.
