title: Sources of self-efficacy belief: development and validation of two scales.
abstract: Self-efficacy belief has been an instrumental affective factor in predicting student behavior and achievement in academic settings. Although there is abundant literature on efficacy belief per se, the sources of efficacy belief have not been fully researched. Very few instruments exist to quantify the sources of efficacy-beliefs. To fill this void, we developed two scales for the two main sources of self-efficacy belief: past performance and social persuasion. Pilot test data were collected from 255 middle school students. A self-efficacy measure was also administered to the students as a criterion measure. The Rasch rating scale model was used to analyze the data. Information on item fit, item design, content validity, external validity, internal consistency, and person separation reliability was examined. The two scales displayed satisfactory psychometric properties. Applications and limitations of these two scales are also discussed.
