What Makes for a Good Day? Competence and Autonomy in the Day and in the Person

Abstract

This diary study examined the proposal that satisfaction of two psychological needs, competence and autonomy, leads to daily well-being. Between-subjects analyses indicated that participants higher in trait competence and trait autonomy tended to have "better" days on average. Independently, within-subject analyses showed that good days were those in which participants felt more competent and autonomous in their daily activities, relative to their own baselines. Other predictors of daily well-being included gender, whether the day fell on a weekend, and the amount of negative affect and physical symptomatology felt the day before. Although past diary studies have tended to focus on threats to daily well-being, the authors suggest that psychological need concepts offer promise for understanding its positive sources.
