Abstract

Objectives: Characterizing the psychometric attributes of the Persian variant of partners in health (PIH) in multiple sclerosis (MS), Diabetes, and Low Back Pain (LBP) patients. Methods: In this cross-sectional study, 183 MS, diabetes, and LBP patients (70 male, 113 female) were treated with PIH post-forward-backward translation. Confirmatory factor analysis was used for studying the factor structure. Cronbach’s α and McDonald’s Ω coefficients were used to analyze PIH internal consistency. We used an interclass correlation coefficient to evaluate test-retest reliability. Criterion validity was determined by studying the correlation of PIH and Short Form (36) Health Survey (SF-36), Diabetes Self-Management Scale (DSMS), and Self-Efficacy in Chronic Disease Self-Management (SES6G). Results: The median age of the participants was 49.73±15.16 years, 113 (61.75%) of them were female, 64 (35.0%) had MS, 66 (36.1%) had diabetes, and 53 (29.0%) had LBP. Content validity was determined across all areas (clarity, relevancy, simplicity) by a content validity index ≥0.82. Additionally, all items were confirmed via a content validity ratio ≥0.78. The outcome of CFA depicts that the statistics presented as model fit were as follows: CFI= 0.938, NFI= 0.899, and RMSEA= 0.085. All PIH items exhibited valid internal consistency (0.886-0.893). The PIH showed sufficient test-retest reliability regarding its corresponding subscales (0.554-0.679). The construct validity was confirmed by the total scores of PIH correlated with the total score of SF-36, SES6G, and DSMS. Discussion: The Persian variant of the PIH showed sufficient validity and reliability as a measure to assess self-management in patients suffering from chronic disease (MS, diabetes, and LBP) © 2022, Iranian Rehabilitation Journal.All Rights Reserved.
