The present study examined whether personal engagement in a leadership course would predict rated performance for the course, and whether qualitative overload would moderate the relationship. Participants were Army Reserve Officer Training Corps (ROTC) cadets participating in a 5-week long leadership assessment course. Participants completed measures of qualitative overload (the extent to which they felt they lacked the skills and expertise required for effective performance) and the degree to which they were engaged in the course during the 4 th week. Results revealed that course engagement was a significant predictor of rated leadership performance, even after controlling for the personality variable of conscientiousness. Course engagement interacted with qualitative overload to predict rated performance, indicating that qualitative overload was a stronger predictor of rated performance for those cadets engaged in the course. Discussion of the results focuses on engagement as a predictor of performance, and how work-related impediments matter more for engaged individuals.When individuals are personally engaged in an activity, they should be more likely to exert increased effort in the face of obstacles, and actually perform better than those who are disengaged from an activity (Brown , 1994) and is evident when an individual feels a sense of responsibility for and commitment to a performance domain so that performance matters to the individual (Britt, 1999(Britt, , 2003a(Britt, , 2003b). The triangle model specifies that individuals are most likely to feel personally engaged in an event when the prescriptions governing performance are clear, the individual has personal control over his or her performance, and the performance domain is relevant to the individual's identity (Schlenker et al., 1994).When an individual is personally engaged in an activity, the self-system of that individual is activated, and a part of his or her self-concept is invested in performance. Therefore, engagement in an activity has implications not only for motivation and performance, but also for emotional consequences following the outcome of performance (Britt, 1999(Britt, , 2003b. Personal engagement in an activity should magnify the emotional consequences of succeeding versus failing at a task because performance outcomes have greater implications for the individual's identity. Britt (1999) found that when soldiers reported a high level of engagement in their jobs, their perceived success in their jobs was related more strongly to their reported levels of depression and overall stress. When soldiers reported a relatively low level of job engagement, their perceptions of job success were less related to reported depression and stress (see also Brunstein, Schultheis, & Grassman, 1998).Because the outcomes of performance matter more to individuals who are engaged in a task, factors that prevent individuals from succeeding at a task should be perceived as particularly frustrating for individuals who report high levels of engagement in...
