Validity and reliability of the Turkish Adherence to Refills and Medications Scale
1Faculty of Health Sciences, Cyprus International University, Northern Cyprus.
Aims:
The aim of the study was to create a Turkish version of the Adherence to Refills and Medications Scale (ARMS-7) and to examine its validity and reliability.
Methods:
The sample of this methodological type study consisted of 100 Turkish patients with chronic disease. In the evaluation of data, the content validity index, Cronbach α, test-retest, item total score correlation, exploratory and confirmatory factor analyses, and adherence statistics were used.
Results:
The scale's content validity index was 0.94, its Kendal W goodness-of-fit test was 0.188 (P = .246), its Cronbach α coefficient was 0.75, and its item total score correlation was between 0.32 and 0.59 (P < .001). The test-retest reliability was also satisfactory with interclass correlation coefficients higher than 0.75.
Conclusion:
The Turkish version of the ARMS-7 is a reliable and valid instrument that can be used in the evaluation of attitudes to adherence to medications and refills based on self-reporting by the chronically ill.
