Assessing Self-Efficacy in Presentation and Moderation Skills
Abstract. By means of two studies, a self-report measure to assess self-efficacy in presentation and moderation skills, the SEPM scales, was validated. In study 1, factorial and construct validity were examined. A sample of 744 university students (41% females; more than 50% between 20 and 25 years) completed newly constructed self-efficacy items. Confirmatory factor analyses (CFAs) substantiated two positively correlated factors, presentation (SEPM-P) and moderation self-efficacy (SEPM-M). Each factor consists of eight items. The correlation patterns between the two SEPM subscales and related constructs such as extraversion, the preference for cooperative learning, and conflict management indicated adequate construct validity. In study 2, criterion validity was determined by means of latent change modeling. One hundred sixty students ( Mage = 24.40, SD = 4.04; 61% females) took part in a university course to foster key competences and completed the SEPM scales at the beginning and the end of the semester. Presentation and moderation self-efficacy increased significantly over time of which the latter was positively associated with the performance in a practical moderation exam. Across both studies, reliability of the scales was high, ranging from McDonald’s ω .80 to .88.
