Occupational Self-Efficacy Scale - Short Form (OSS-SF): Adaptation and evidence of construct validity of the Brazilian version

Abstract

This study aimed to adapt the Occupational Self-Efficacy Scale – Short Form (OSS-SF) to the Brazilian context. Participants were 514 professionals (86.4% women, mean age = 37.91 years, SD = 10.78). The sample was randomly split in two halves, and exploratory and confirmatory factor analyses were conducted to evaluate the factor structure of the Brazilian OSS-SF. Excellent goodness-of-fit indexes were achieved. Convergent validity was assessed using the Job-related Affective Well-being Scale and the Maslach Burnout Inventory. Correlations in the expected direction and magnitude were achieved. Further, significant differences were found in the levels of occupational self-efficacy among professionals who exhibited prevalence of job-related positive affect instead of job-related negative affect. The OSS-SF presented adequate psychometric properties, which suggests its usefulness in evaluating occupational self-efficacy in the Brazilian context.
