Session presented on Friday, July 25, 2014: Purpose: The purpose of this study was to translate the self-efficacy for appropriate medication use into Thai and then examine the validity and reliability of this version of questionnaire. Methods: Responses to the 13-item Thai version of the Self-Efficacy for Appropriate Medication Use Scale (SEAMS) were collected from 100 Thai post-MI patients. None of the 13 items violated any assumption for factor analysis. Hypothetical exampling and factor analysis were performed. Results: Factor analysis revealed three components for determining the self-efficacy for medication adherence: the patient's self-confidence (six items), complexity of medication (four items), and daily life change (three items). The instrument showed acceptable validity and reliability. Conclusion: The SEAMS may be used in the clinic to measure self-efficacy for medication adherence among Thai post-MI patients.
