The purpose of this study was to provide preliminary analysis of reliability and validity of scores on the "Self-Efficacy Self-Report Scale", which was designed to assess general self-efficacy in students aged 10 to 17 years. Confirmatory factor analysis on cross-validated samples was conducted revealing a marginal fit of the data to the 19-item unidimensional scale. Studies of internal consistency and test-retest reliability revealed adequate levels of total scale consistency. Criterion-related validity estimates were moderate to strong. Norms and a test protocol are provided to encourage free use of the scale for student assessment and research purposes. (Contains 1 table and 2 figures.)
