On the Importance of Balanced Need Fulfillment: A Person-Centered Perspective

Self-determination theory proposes that the fulfillment of the three basic psychological needs of autonomy, competence, and relatedness is important for optimal functioning. While support for this proposition have been well-documented, little attention has been paid to how these needs interact within individuals and whether having equally low, medium or high level of need fulfillment (i.e., balanced need satisfaction) has additional effects over and above the aggregated need fulfillment itself. The present study addresses these questions by examining the importance of having balanced versus imbalanced need fulfillment by adopting latent profile analysis, making it possible to distinguish quantitative and qualitative need-related differences. This research also documents the relations of these need profiles in relation to theoretically-relevant profile predictors (perceived interpersonal behaviors) and outcomes (affect and passion). A total of 1094 adults (female = 746,M-age = 26.00,SDage = 7.69) participated in this study. A four-profile solution appeared to be the most optimal: (1) balanced, all needs are highly satisfied, (2) imbalanced, only relatedness is highly satisfied, (3) balanced, all needs are average, and (4) balanced, all needs are frustrated. Interestingly, these profiles differed from one another in terms of obsessive passion, negative affect, and, to a smaller extent, positive affect, but not harmonious passion. Finally, profile membership was predicted by the perceived need nurturing global factor as well as by some of the specific factors. These results support the hypothesis that, apart from need fulfillment, need balance is also important for wellbeing and optimal functioning.
