Examination of reliability and validity of the “Self-Efficacy Scale of Occupation-focused Practice”

Abstract

This study investigated the reliability and validity of “The Scale of Self-Efficacy of Occupation focused Practice.” Subjects were registered occupational therapists and occupational therapy students in Japan. Effective responses were provided from 246 subjects using a web questionnaire. Factor analysis revealed 31 items and 3 factor structures. Covariance structure analysis based on this prediction indicated confirmation of model fitness with the goodness-of-fit index CFI=.911, while RMSEA=.096 was not a good fit. However, a certain level of construct validity was confirmed. Internal consistency reliability was evaluated using Cronbach's α coefficient. Cronbach's α of each factor were .970–.981, indicating that our developed scale was reliable and valid.
