Context: Diabetes mellitus (DM) is a common disorder, causing undesirable medical and economic consequences. A simple, reliable and validated self-report instrument could lead to a better understanding of non adherence to treatment and may identify new treatment modalities. For this purpose, the eight-item Morisky Medication Adherence Scale (MMAS-8) © 2006 Donald E. Morisky was developed. The aim of this study was to evaluate the validity and reliability of the MMAS-8 among Turkish diabetes mellitus patients.

Methods: This was a cross sectional descriptive study. A total of 199 patients were enrolled in the study. Turkish translation of Morisky-8 item scale consisted forward translation, reconciliation, back translation, back translation review, developer review, pilot testing and the final translation.

Results: Cronbach’s alpha test of internal consistency was calculated at alpha = 0.890 for the eight items MMAS-8 scale. CFA demonstrated the scale fitted CMIN/DF=1.194, GFI = 0.970, CFI = 0.995, RMSEA = 0.031. Poor glycemic control (HbA1c < 7) was significantly high in the low adherence group compared with high and medium adherence group (P=0.001, LR=21.79). Approximately 94% of the low adherence patients were in the poor glycemic control group.

Conclusion: The MMAS-8 Turkish version was determined to be a valid and reliable scale in diabetic patients. This self-report scale could function as a screening tool in busy clinics to identify patients who are low adherent to medication treatment. Moreover, the MMAS-8 Turkish version could help to improve adherence and develop new treatment strategies.
