Understanding treatment adherence in affective disorders: a qualitative study

Abstract

The objective of this study was to explore the perspective of depressed patients, their family and mental health professionals from their community mental health centre (CMHC) on factors related to treatment adherence. We conducted eight separate focus groups involving patients, their families and their therapists from three CMHCs. A total of 52 persons were involved. The groups explored patients' and family's explanatory model of depression, perceptions about the course of the disease, the role of medication and other treatments, the main causes of non-adherence, and interventions which would help increase it. Patients and families had a complex cognitive model of depression, which combined intrinsic vulnerability, psychological suffering during childhood and adolescence, and adverse life events. Drugs as well as other treatments were considered helpful, more so by patients than by family members. Denial of the disease and need to test its continuing presence were the main causes of non-adherence for patients, while adverse reactions did not play a relevant role. Mental health professionals tended to underestimate non-adherence in depressed patients, and did not question their patients about medication adherence. Family members needed more information on depression, on how to manage their relatives, as well as psychological and social support for themselves. The study allowed for the identification of a number of specific interventions aimed at facilitating treatment adherence, such as providing more information to patients and families, and training doctors and nurses in effective prevention and management of non-adherence.
