The Patient Activation Measure (PAM) is a 13-item questionnaire that assesses patients’ knowledge, skills, and confidence in self-management. The current study aimed to translate the American version of the PAM-13 into Persian and test the psychometric properties of the Persian version among chronic patients. This cross-sectional study was conducted on 438 chronically ill patients in Rafsanjan, Iran from May to November 2019. The American version of the PAM-13 was translated into Persian using a standardized forward–backward translation method. Internal consistency, test-retest reliability, face and content validity, as well as construct validity (structural and convergent validity) were all assessed. The content validity index of the Patient Activation Measure-13 Persian (PAM-13-P) was 0.91. Exploratory and confirmatory factor analyses showed that the PAM-13-P had a meaningful structural validity. The PAM-13-P scores were negatively correlated with the Partner in Health Measure (PIH) (r = −0.29, p < 0.001). In addition, the PAM13-P scores were positively correlated with the Satisfaction with Life Scale (SWLS) (r = 0.31, p < 0.001). The internal consistency was 0.88, and the repeatability was excellent [Intraclass Correlation Coefficient (ICC):0.96 and confidence interval (CI): 0.94–0.98]. This study demonstrates that the PAM-13-P is a reliable and valid measure for assessing activation among chronically ill patients. The PAM-13-P scale assesses the level of self-management of chronic patients and identifies appropriate care strategies to meet their needs.
