The Interaction between Basic Psychological Needs, Decision-Making and Life Goals among Emerging Adults in South Africa

The interaction between emerging adult psychological well-being and decision-making, in South Africa, has not been explicitly explored in Self-Determination Theory. Life goals have been thought to play a role in the interaction between basic psychological needs and decision-making to promote psychological well-being. The current study, therefore, aimed to examine whether the decision-making styles employed, and the life goals which were deemed important, contribute to the understanding of the satisfaction or frustration of the basic psychological needs of emerging adults in South Africa. Data were collected cross-sectionally, using a secure, online survey among 1411 participants. The interaction between decision-making, life goals and basic psychological needs variables were examined using descriptive statistics, Pearson correlations and hierarchical regression analyses. The results in the study suggest that adaptive (vigilant) decision-making and intrinsic life goals were significant predictors for the satisfaction of the basic psychological needs. Some forms of maladaptive decision-making and extrinsic goals were predictors of the frustration of basic psychological needs. The variance explained by the various models were between 15.6–32.6%, with the results suggesting all models were significant. The results provide a novel contribution to emerging adult well-being in South Africa and Self-Determination Theory, with the implications for society, research and practice discussed.
