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.


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.


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.


The SEAMS may be used in the clinic to measure self-efficacy for medication adherence among Thai post-MI patients.
