Abstract
We previously prepared the “Self-assessment scale of the competencies of occupational therapists (OTs) engaged with community-dwelling elderly adults with disabilities” consisting of 68 items, using the Delphi technique. The purpose of this study was to investigate the reliability and validity of this scale. Questionnaires were sent to randomly chosen OTs engaged with community-based rehabilitation (CBR) of elderly adults who belong to Japan OT association. We performed exploratory factor analysis (EFA) and covariance structure analysis (CSA) after evaluating sample characteristics. Internal consistency reliability (ICR) was evaluated using Cronbach's α coefficient. As a result, 363 OTs who answered all items were included. This scale was structured by 5 factors and 30 items. CSA was performed based on this prediction, and revealed CFI=.921 and RMSEA=.055, respectively, in which sufficient applicability of the constructive concept was confirmed. ICR was calculated as Cronbach's α =.79〜.95. Our developed scale was reliable and valid.
