Development and Validation of the Sources of Self-Efficacy Inventory (SOSI): Exploring a New Measure of Teacher Efficacy.
Kieffer, Kevin M.; Henson, Robin K.
This paper describes the development and construct validation of a new instrument of teacher efficacy, the Sources of Self-Efficacy Inventory (SOSI), which was created to address shortcomings in previous measures that purported to measure this construct. Development of the SOSI was based on a model of teacher efficacy posited by M. Tschannen-Moran, A. Woolfolk Roy, and W. Roy (1998) that described four important areas of efficacy building information as proposed by A. Bandura (1997). The SOSI was examined with a sample of 252 undergraduate students in an educational psychology course. Factor analysis of the 35 SOSI items yielded 4 interpretable factors that contained many of the target items. However, many items were associated with non-intended factors, and it was apparent that item and subscale revision was necessary. Results of a confirmatory factor analytic study of another teacher efficacy instrument, the Teacher Efficacy Scale, are presented to further explore the teacher efficacy construct. An appendix presents items from the SOSI. (Contains 2 tables and 21 references.) (Author/SLD)
