Psychometric Properties of Turkish Version of Perceived Efficacy and Goal-Setting System

Goal setting is essential in pediatric rehabilitation to enhance participation and meaningful goals. This study examined the construct validity, internal consistency, and test-retest reliability of the Turkish version of the Perceived Efficacy and Goal-Setting System (PEGS) in children with disabilities. A methodological cross-sectional design was used with 120 children aged 7 to 9 years (90.9% cerebral palsy, 9.1% spina bifida), their caregivers, and teachers from three rehabilitation centers in Turkey. The adaptation process followed WHO guidelines. Data were collected with PEGS-Child, PEGS-Caregiver, PEGS-Teacher forms, and demographics. Exploratory and confirmatory factor analyses confirmed a single-factor structure consistent with the original, with factor loadings above 0.320 and acceptable fit indices (CFI > 0.90, RMSEA < 0.08). Cronbach's alpha ranged from 0.72 to 0.77. Test-retest reliability was high (ICC = 0.876-0.943). The Turkish PEGS is valid and reliable, supporting child participation in goal-setting and fostering collaboration between home and school.
