Abstract
The primary domain of concern for occupational therapy is a knowledge base that supports an understanding of the range of influences impacting the activity participation of individuals. Self-efficacy beliefs are reported to underpin a person's capacity to initiate behaviors and produce performance outcomes. The purpose of this study was to test a measure of self-efficacy against which occupational performance outcomes may be predicted in adolescents. This study examined the extension of a generalized measure of self-efficacy, the Perceived Self-Efficacy (PSE) scale, for use with adolescents. Psychometric properties of the PSE scale were tested in a sample of 850 adolescents aged 12 to 18 years. The PSE scale exhibited adequate reliability and validity consistent with past research and theory. A one-way analysis of variance produced significant differences in responses by age, demonstrating support for perceived self-efficacy as a developing self-construct during the early transition adolescent years. The use of the PSE scale within the occupational therapy context is highlighted.
