In addition to demographic information, two questionnaires WHOQoL-BREF and SF-36 questionnaires were used for data collection. Cronbach’s alpha coefficient was used for scale reliability. We conducted an exploratory factor analysis for the investigation of construct validity. Convergent and discriminant validity were analyzed using Spearman correlation coefficient. To determine the relationships between the eight domains of SF-36 and four domains of the WHOQoL-BREF, structural equation modelling was performed.Results: Cronbach’s alpha coefficients were acceptable for all domains of both WHOQoL-BREF (0.69– 0.86) and SF-36 (0.63 − 0.92) questionnaires. The principal component analysis showed two separate factors: one for all domains of SF-36 and another for all domains of WHOQoL-BREF. Spearman correlation coefficients of both instruments were partly to strongly correlated with most domains (r ≥ 0.40). Correlations for domains with similar constructs were stronger than those measuring varied constructs. Structural equation modelling recommended approximately moderate relationships among the SF-36 and WHOQoL-BREF domains.Conclusion: Our study suggests that SF-36 and WHOQoL-BREF are reliable instruments for clinical and research uses, respectably. However, results of the goodness of fit showed that the WHOQoL-BREF was fitted well. Also, the WHOQoL-BREF can be considered more suitable for the study population.Keywords: quality of life, type 2 diabetes, WHOQoL-BREF, SF-36, Iranhttps://www.dovepress.com/comparison-of-sf-36-and-whoqol-bref-in-measuring-quality-of-life-in-pa-peer-reviewed-article-IJGMquality of lifetype 2 diabeteswhoqol-brefsf-36iran
