Validation of Scale of Anxiety Symptoms in Clinical Sample of Adolescents

Aim of the Study: The goal of present research was validation of a newly developed indigenous scale of anxiety symptoms in clinical sample of adolescents by Khan et al., (2022). The scale already gone through procedure of items generation, exploratory factor analysis (EFA) and inter-rater reliability. Methodology: Confirmatory factor analysis (CFA) as well as investigation of psychometric properties was done on clinical sample in present study making it a promising indigenous scale to assess anxiety symptoms in the adolescents. CFA was done on sample of 220 (M=14.25, S.D. =1.86) on Analysis of Moment Structure (AMOS) version 23. Findings: Final model consist on the 26 items and 2 factors. Covariances were added across various items within same factor which help the results to improve. Model gave significant model fit indices values (TLI=0.8, RMSEA=0.09, CFI=0.83). The overall scale and subscales showed high Cronbach Alpha reliability with value 0.91. Psychometric properties include convergent, discriminant validity as well as test-retest reliability were also investigated giving values of 0.92, 0.69 and -0.34 respectively. Conclusion: This scale can be effectively used across clinical setting to assess anxiety symptoms in adolescents as well as for research purposes.
