Translation and Validation of the Taiwanese Version of the Self-Efficacy for Appropriate Medication Use Scale

Aims and objectives: To translate and validate a Taiwanese version of the Self-Efficacy for Appropriate Medication Use Scale (SEAMS). Background: The major barrier in the management of atrial fibrillation is the lack of selfefficacy to medications adherence. Patients’ knowledge of the nature of atrial fibrillation and cardiovascular, cerebrovascular risk factors and anticoagulants is a significant factor affecting individuals’ adherence. However, few instruments have been developed to assess patients’ self-efficacy to medications adherence and none has been translated into Taiwanese. Design: This study used a standard ‘‘forward-backward’’ procedure, which was used to translate SEAMS into Taiwanese language. Reliability was tested for internal consistency. Validity was confirmed using criterion-related validity. Methods: Data collection for this research occurred from October 13, 2015 to October 26, 2016. The sample included atrial fibrillation outpatient. Participants simultaneously completed the Taiwanese version of the Self-Efficacy for Appropriate Medication Use Scale (SEAMS-T). A total of 151 individuals completed the questionnaire. Results: Coefficient alpha was 0.931 for atrial fibrillation patients. Conclusions: Findings provide support for the validity of the Taiwanese version of the Self-Efficacy for Appropriate Medication Use Scale (SEAMS-T). Relevance to clinical practice: The translation and validation of an instrument evaluating the self-efficacy for medication adherence in atrial fibrillation contribute to assessing the provided educational intervention.
