Examining the role of self-efficacy and three types of outcome expectations in weight training.

This study examined the predictive utility of self-efficacy and three types of outcome expectations (physical outcomes, social outcomes, and self-evaluative outcomes) on students' behavioral intentions and actual behaviors in a beginning weight training class. A total of 137 participants (62 men, 75 women; M(age) = 21.4 yr., SD = 2.0) completed questionnaires assessing beliefs and intentions toward weight training. Attendance and workout log entries were used as a measure of actual behaviors. Regression analyses indicated that physical outcome expectations and self-efficacy emerged as significant predictors of students' behavioral intentions and actual behaviors. Findings of this study were interpreted from self-efficacy theory.
