Backgrounds: Being aware of the rate of satisfaction with treatment can be helpful in predicting treatment adherence and compliance with medical advices. Thus, measuring this parameter is important both in daily clinical care and in biomedical research. Due to unavailability of a tool to measure treatment satisfaction with medicines in Persian, this study embarked on translating and psychometrically evaluating the Persian version of the Treatment Satisfaction with Medicines Questionnaire (SATMED-Q) in chronically-ill patients.
Methods: This cross-sectional study was conducted in two main phases: translation and validation. The translation process was carried out based on Wild’s model (2005). Face validity (20 chronically-ill patients), content validity (10 experts), construct validity including confirmatory factor analysis (225 chronically-ill patients) were used to establish the validity of the questionnaire. Besides, reliability of the questionnaire was assessed based on internal consistency using Cronbach alpha coefficient as well as intra-class correlation coefficient (51 chronically-ill patients). The gleaned data was analyzed using SPSS20 and LISREL8.5.
Results: To explore face and content validity, the items were modified based on the opinion of patients and experts. Confirmatory factor analysis showed acceptable fit for six factors. Internal consistency was obtained 0.875 and the intra-class correlation coefficient was 0.739.
Conclusion: The Persian version of the Treatment Satisfaction with Medicines Questionnaire has sufficient reliability and validity for assessing the treatment satisfaction with medicines in chronically-ill patients, and it is advisable to use it in clinical studies, clinical setting, education, and management.
