Adaptation of the Quality of Sibling Experience Scale for Individuals with Special Needs Siblings into Turkish: A Methodological Study

Abstract

Purpose: The relationship between siblings, which is a lifelong bond, affects both the individual with special needs and their healthy sibling in many ways. This study was conducted to do the Turkish validity and reliability study of the Siblings’ Experience Quality Scale (SEQS).
Material and Methods: The study was carried out with individuals who were aged over 18 and had a sibling enrolled in the Guidance and Research Center of a province. Shapiro-Wilk normality test, Pearson correlation analysis, content validity index, Cronbach’s Alpha coefficient, McDonald’s omega test, confirmatory factor analysis, and t-test were used in data analysis.
Results: The healthy siblings of 171 students with special needs voluntarily participated in the study. The scale explained 54.8% of the total variance. The omega reliability coefficient value for the overall scale was determined as 0.81. As a result of CFA, the fit indices were found as X2=247.893, df=128, X2/df=1.93, RMSEA=0.074, GFI=0.86, IFI=0.85, NFI=0.73, TLI=0.81, CFI=0.84, and AGFI=0.819.
Conclusion: The SEQS was proven to be a valid and reliable measurement tool in the Turkish population
