Adherence to Antidepressants Medication Among Patients with Depression in Oman: A Cross-Sectional Study

Aim: Poor adherence to medication can be a major barrier to the successful management of depression. This study aimed to explore the level of medication adherence among patients with depression in Oman. Design: This cross-sectional study enrolled 206 participants with depression who completed the Medication Adherence Rating Scale (MARS) and a demographics sheet. Results: The average adherence score was 5.8 (SD=1.7, Mdn=6). Patients who lived with their families had significantly higher adherence levels to medication (mean (m) =6.76; SD=2.11) compared with their counterparts who lived alone (m=5.75, SD=1.63). Patients who did not have a chronic illness had significantly better adherence to medication (m=6.04; SD=1.63) compared with participants without chronic illnesses. Conclusion: Low medication adherence is a significant problem for many patients with depression. There are a number of factors that influence adherence, including family support and chronic illnesses. Healthcare providers should provide clear and accurate information about the condition and treatment, involve patients in decision making, address the stigma surrounding mental illness and involve family members in the treatment plan.
