Adherence to drug treatment is a multidimensional concept. It is affected by many factors, such as physiological, psychological, family, environmental and social conditions. However, relatively little is known about the relationship between adherence to medication and psychosocial adjustment. The aim was to explore the relationship between adherence to antidiabetic drugs and the psychosocial adjustment of patients with type 2 diabetes mellitus. This cross-sectional descriptive correlational study was conducted between March and June 2018. A convenience sample of participants was recruited from seven internal disease outpatient clinics at a public tertiary hospital, located in a large city that serves as a gateway to nearby rural and urban areas in the north-west region of Turkey. Data were collected using the Adherence to Refills and Medications Scale (ARMS-7), and the Psychosocial Adjustment to Illness Scale–Self Report (PAIS–SR). This study is reported in accordance with STROBE. Pearson’s correlation analysis found a significant weak positive correlation between all domains of the PAIS–SR and the total scores on the ARMS‐7. The participants’ scores on medication refill were found to be significantly and positively correlated with all of the PAIS–SR domain scores except the sexual relationships domain. Psychosocial care could play a crucial role in improving drug regimen adherence among patients with diabetes. Therefore, nurses should integrate psychosocial care into daily practice.
