Summary
The coexistence of depression and medical illness has been the focus of a great deal of attention in the past several years. Depression appears to occur in at least 25% of medical patients, although estimates vary based on measurement criteria, type and stage of medical disease, and level of depressive severity [1, 2]. Depression has also been associated with poorer health outcomes in these diseases. Depression may influence the development and progression of diseases directly via physiological pathways or indirectly via behavioural pathways [3].
Adherence to treatment regimens is one possible behavioural pathway by which depression affects physical health. Adherence is the degree to which a person's behaviour (e.g. taking medications, attending treatment sessions, executing lifestyle changes) coincides with medical or health advice [4]. Adherence is critical for the prevention and treatment of medical diseases. Unfortunately, adherence is less than optimal across a wide range of medical regimens [5]. Individuals who are depressed may be less likely to adhere to various aspects of their treatment regimens, and this lack of adherence may produce poorer health outcomes.
There is a large literature on predictors of adherence. A substantial number of variables have been associated with adherence, but findings across studies have been inconsistent [6]. Depression has emerged as one of the few promising predictors of treatment adherence among medical patients [7]. There are many reasons to hypothesise that depression may negatively influence an individual's willingness and capacity to adhere to a treatment regimen.
