A validity and reliability study of the Work and Social Adjustment Scale (WSAS) Youth and Parent Forms in the Turkish population

This study assessed the validity and reliability of the Youth and Parent Forms of the Work and Social Adjustment Scale (WSAS) in the Turkish population. The patient group comprised 298 young patients aged 8 to 18 with any anxiety disorder, while 107 healthy young people formed the control group. Participants completed assessments, including the Screen for Child Anxiety-Related Disorders and the Pediatric Quality of Life Inventory (PedsQL), alongside the WSAS, while parents also completed the PedsQL and the WSAS. After 2 weeks, 100 individuals from the patient group were reevaluated for test-retest reliability. Results showed satisfactory validity and reliability, supported by statistical analyses, including Rasch analysis and Cronbach's alpha coefficient. The WSAS demonstrated validity across all evaluations and reliable internal consistency (Cronbach's alpha: parent form = .755, youth form = .750), test-retest reliability (correlation coefficients: parent form = 0.934, youth form = 0.937). Overall, the WSAS proved valid and reliable in the Turkish language. (Bulletin of the Menninger Clinic, 89[1], 27-51)
