Confirmatory factor analysis was used for studying the factor structure. Cronbach&rsquo;s &alpha; and McDonald&rsquo;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).<br> <strong>Results:</strong> The median age of the participants was 49.73&plusmn;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 &ge;0.82. Additionally, all items were confirmed via a content validity ratio &ge;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.<br> <strong>Discussion:</strong> 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).</div> Chronic disease, Self-management, Partners in health scale, Validity, Reliability 529 538 http://irj.uswr.ac.ir/browse.php?a_code=A-10-1485-1&slc_lang=en&sid=1 Hooman Saghebi h.saghebi@yahoo.com 0000-0001-9157-3119 No Department of Occupational Therapy, School of Rehabilitation, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
