This study examined the relationships between two kinds of achievement motivation (self-fulfillment and competition) and two aspects of self-esteem (level and instability). University students (N=57) participated in a one-week diary survey. Hierarchical regression analysis revealed a level×instability interaction of selfesteem on self-fulfillment motivation. A high level of self-esteem was associated with strong motivation for self-fulfillment when self-esteem was stable. In contrast, high level of self-esteem was associated with weak motivation for self-fulfillment when self-esteem was instable. Neither level nor stability of self-esteem was significantly associated with motivation for competition. Discussion focused on the importance of considering both level and instability of self-esteem in analysis of achievement motivation.
