Abstract

Although research on self-concept is extensive, few studies have examined the relationship between specific aspects of self-concept structure (e.g., self-concept clarity) and self-regulation constructs (e.g., goal commitment). In addition, research has linked aspects of self-concept structure with well-being outcomes, but less is known about the mechanisms involved in these relationships. This research addresses these two issues by examining self-concept structure (self-concept clarity and self-concept differentiation) as antecedents of key self-regulatory mechanisms (goal commitment and goal conflict) and how these linkages may help explain connections between self-concept structure and well-being and performance. More specifically, two studies examined these relationships, with Study 1 investigating these variables in individuals’ lives in general and Study 2 focusing on these variables in the work context. Regarding self-regulatory mechanisms, SCC was related to goal commitment and SCD was related to both goal commitment and goal conflict. For psychological well-being, SCC was related to eudaimonic, hedonic, and work engagement, whereas SCD was related to eudaimonic and hedonic well-being. In addition, goal commitment was related to work engagement and goal conflict was related to eudaimonic well-being and positive affect. Finally, for performance-related outcomes, SCC was positively related to in-role job performance. In addition, goal commitment was related to goal progress and in-role job performance. However, results for the indirect effects were mixed. Taken together, these results suggest that aspects of self-concept structure may have notable implications for self-regulatory mechanisms, psychological well-being, and performance outcomes.
