Assessment of the Psychometric Properties of the Persian Version of the Cardiac Self-Blame Attribution (CSBA-P) Scale in Patients With Cardiovascular Disease

Abstract

According to the studies done in Iran, there has been no study investigating self-blame attributions in patients with cardiovascular disease. Moreover, there has been no standard scale for assessing self-blame attributions available in Persian. Hence, this study was conducted to determine the psychometric properties of the Persian version of Cardiac Self-Blame Attribution (CSBA-P) Scale in patients with cardiovascular disease. In this 2019 methodological study, 400 patients with cardiovascular disease completed the Persian version of the Cardiac Self-Blame Attribution scale. We evaluated the face, content, and construct validity (both exploratory and confirmatory) of the measure. The results of the confirmatory and exploratory factor analysis extracted a separate factor explained 56.249% of the variance. One factor fit model was confirmed according to standard measures such as RMSEA = 0.074, CMIN/DF = 2.454. The reliability of the scale was calculated and confirmed with a Cronbach coefficient of 0.938, construct reliability of 0.938, and ICC of 0.895. The Persian version of the Cardiac Self-Blame Attribution scale (CSBA-P) yielded acceptable validity and reliability. Thus, this scale can be used in future research to assess self-blame attributions among cardiac populations who speak Persian.
