Psychosocial Intervention to Reduce Self-stigma and Improve Quality of Life Among People With Mental Illness in Chile

Implementing a Psychosocial Intervention to Reduce Self-stigma and Improve Quality of Life Among Mental Health Outpatients in Chile: a Pilot Randomized Controlled Trial

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.

Study Overview

• Status: Completed
• Conditions: Schizophrenia; Schizoaffective Disorder; Bipolar Disorder
• Intervention / Treatment: Behavioral: Intervention to reduce self-stigma among people with mental illness; Behavioral: Control

Detailed 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).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Intervention; Intervention to reduce self-stigma among people with mental illness + Usual care	Behavioral: Intervention to reduce self-stigma among people with mental illness; This is a 10-session group intervention (held once a week), each lasting approximately 90 minutes, taking place where the participants receive mental health treatment. The intervention is informed by the following key areas: (1) recovery perspective of mental health and severe mental disorders; (2) constructivist epistemology approach to learning, using cases and users' experiences; and (3) psychotherapeutic and collective narrative practices, to address internalized problems and challenges shared among the group members, respectively.
Placebo Comparator: Control; Usual care	Behavioral: Control; Generally, each community mental health center in Chile includes two full-time psychologists, a full-time social worker and half-time occupational therapist, nurse, and psychiatrist. This team mainly offers psychiatric medication, psychotherapy, and psycho-education for users and relatives. They do not offer any specific intervention to tackle stigma among providers.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Self-stigma	Internalized Stigma of Mental Illness Scale (ISMI) (Rishter et al., 2003). A Chilean version of this instrument was used during the study.	Baseline (month 6); First follow-up assessment (change from Baseline ISMI scores at month 10); Second follow-up assessment (change from Baseline and 1st follow-up ISMI scores at month 14)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Quality of Life	Seville Quality of Life Questionnaire (CSCV) (Gómez de Regil, 2016). A Chilean version of this instrument was used during the study.	Baseline (month 6); First follow-up assessment (change from Baseline CSCV scores at month 10); Second follow-up assessment (change from Baseline and 1st follow-up CSCV scores at month 14)
Psychopathology	Positive and Negative Syndrome Scale (PANSS). A Chilean version of this instrument was used during the study.	Baseline (month 6); First follow-up assessment (chance from Baseline PANSS scores at month 10); Second follow-up assessment (change from Baseline and 1st follow-up PANSS scores at month 14)
Treatment adherence	Adherence to medical appointments during the study. Time remaining in treatment is estimated by counting the number of days between randomization to the time of the last mental health service received. Medical records at each community mental health center are reviewed to obtain this data.	Baseline (month 6); First follow-up assessment (change from Treatment Adherence Baseline at month 10); Second follow-up assessment (change from Treatment Adherence Baseline and 1st follow-up at month 14)
