Objective: To validate a Greek version of the structured self-reported 8-item Morisky Medication Adherence Scale MMAS-8 and determine its psychometric properties in patients with chronic illnesses. Methods: A cross-sectional survey was conducted in a small public hospital and a public health care centre, in a rural town in western Greece. The sample consisted of 100 patients with various chronic illnesses. Data were collected between January-May 2011, on the Greek version of the MMAS-8 and Beliefs about Medicines Questionnaire BMQ. Results: Scale’s reliability analysis revealed an overall Cronbach’s alpha of 0.753 and the corrected item to total correlations, were greater than 0.30 for each of the 8 items comprising the medication adherence scale, showing good internal consistency. Convergent validity was supported by a significant correlation between the present scale’s total score and the BMQ-Specific Necessity score Spearman’s rho = 0.492, p < 0.001. Conclusion: The current study showed acceptable reliability and validity of the Greek version of the 8-item MMAS to measure adherence to medications for various chronic illnesses. The validated Greek version of the MMAS-8 can help towards understanding adherence barriers in Greece so as to develop effective strategies to increase adherence and reduce the costs.
