About

The principal objective of this pilot trial is to evaluate the effectiveness of a psychosocial intervention to reduce self-stigma and improve treatment adherence and quality of life among people with a severe mental illness who attend to Community Mental Health Centers in Chile. The intervention is based on recovery and narrative therapy and considers 10 group sessions, mainly with patients, but also integrating relatives and professionals in some of the activities.

Full description

It has been shown that stigma is one of the main barriers faced by individuals with mental illness, negatively impacting their service use and continuity of treatment. Additionally, given its impact on self-esteem, personal empowerment, and social inclusion, stigma greatly affects the quality of life of this population.

Consequently, a pilot randomized controlled trial (RCT) with two arms (intervention group vs. control group) was designed and implemented. Participants were identified and recruited from two community mental health centers located in Central Chile. The intervention group, in addition to usual care, received a psychosocial intervention based on narrative therapy, recovery and psychoeducation which was specially tailored for this population by the authors.

The sample corresponds to 76 individuals with a severe mental illness (ICD-10), currently treated in the two participating Community Mental Health Centers (COSAM). The category "severe mental illness" includes patients with diagnosis of schizophrenia, schizoaffective disorder, bipolar disorder and severe depressive disorder with psychotic symptoms. Finally, those two clinics were chosen by convenience in order to facilitate the implementation of this study.

Before and after the intervention, the participants' self-stigma (Internalized Stigma of Mental Illness, ISMI), treatment adherence (weeks in treatment), and quality of life (Sevilla Quality of Life Scale) were measured. In addition, the following control variables were also evaluated, due to their influence on the principal outcomes: 1) sociodemographic information, 2) symptom presence and severity (Positive and Negative Syndrome Scale, PANSS), and 3) alcohol consumption (The Alcohol Use Disorders Identification Test, AUDIT).
