This article extends recent work on the relationship between personality and career self-efficacy by examining relationships across two new inventories with scales for identifying human strengths. The Healthy Personality Inventory (HPI) has 17 content scales tapping an array of positive personality measures. The CAPA Confidence Inventory (CCI) has 6 broad, 27 basic, and 6 engagement styles measures of career self-efficacy. In a sample of college students, hypothesized correlations between personality and self-efficacy were generally confirmed. A number of unexpected relationships also were found, such as the HPI Creative scale predicting social and enterprising confidence. These inventories show promise for continued research, theory development, and assessment practice. (Contains 6 tables.)
