Abstract

Introduction: Most elderly people with chronic diseases use multiple medications simultaneously, and therefore adherence to the drug is important among these people. This study was designed to assess the validity and reliability of the Persian version of Self-Efficacy for Appropriate Medication Use Scale (SEAMS). Methods: In this study, 30 elderly people aged 60 and older were eligible to enter the study by random sampling from health centers in Gonbad-e-Kavus based on medical records codes. Demographic data, MMSE questionnaire and SEAMS scale were completed by participants. Besides the face and content validity of the questionnaire, reliability and internal consistency of the SEAMS scale were evaluated using Cronbach's alpha, split-half and test-retest methods by SPSS software version 18. Results: The Average age of participants was 67.9 years. The face validity was studied qualitatively (interview with 10 elderly in the target group) and content validity (expert panel) was confirmed. The internal consistency was 0.81 by Cronbach's alpha and 0.77 by split-half method. Also, the external reliability was assessed by test-retest method and Pearson correlation coefficient was 0.97. Conclusion: According to the results, the SEAMS scale has a good validity and reliability among elderly in Iran. Therefore, it is recommended for evaluating adherence to treatment among elderly with chronic diseases.
