Saima Liaqat Saima Kalsoom (PhD)

Abstract


In collectivistic societies social and interpersonal cohesion is deeply valued as indicator of tolerance and measuring interpersonal tolerance demands indigenous measure which is linguistically and culturally relevant. Therefore, this study intended to translate and adapt the Interpersonal Tolerance Scale (Thomas et al., 2016) into the indigenous language Urdu from English. Further this study also aimed to establish the construct validity of the translated version of this scale. A correlational research design was employed using convenience sampling strategy to recruit the sample. The study recruited 100 married individuals as participants. Study comprised of two phases. Phase I was carried out through rigorous process of forward and backward translation and adaptation method of the Interpersonal Tolerance Scale. Committee approach was used by selecting subject matter experts to ensure equivalence in linguistic and conceptual domain. Phase II objectified the construct validation of the Interpersonal Tolerance Scale. Confirmatory factor analysis (CFA) was carried out to establish the construct validity. The findings showed an acceptable model fit indices as indicated by reporting all the indices i.e., (χ²/df=1.86 CFI=.90 RMSEA= .05 & SRMR=.01). These model fit indices and values of inter scale correlations of interpersonal tolerance scale as composite score with subscales (r= .87 to -.72) confirmed the psychometric properties of the Urdu-translated and adapted version of Interpersonal Tolerance Scale. These evidences demonstrated that the translated and adapted version of interpersonal scale is reliable (α = .92 to .91) and valid tool for measuring interpersonal tolerance for married individuals in the traditional and collectivistic culture context of Pakistan.Keywords: Interpersonal tolerance scale, translation, adaptation,
