Dyadic effects of stigma on quality of life in people with schizophrenia and their family caregivers: Mediating role of patients' perception of caregivers' expressed emotion.

ABSTRACT

Schizophrenia, as a stressful diagnosis, profoundly impacts the whole family, especially people with schizophrenia and their caregivers. This study tested the potential mediating role of expressed emotion in the association between mental health stigma and quality of life in caregiver-patient dyads. Using a 2-wave longitudinal design with a 6-month interval between assessments, 161 dyads of patients with schizophrenia and their family caregivers (one patient and one caregiver) completed measures of mental health stigma, expressed emotion, and quality of life. The results showed that patients' self-stigma had no significant actor or partner effect on expressed emotion or quality of life. In contrast, caregivers' stigmatizing attitudes toward patients had a significant partner effect on patients' perception of caregivers' expressed emotion and quality of life. The mediating effect of patients' perception of caregivers' expressed emotion in the association between caregivers' stigmatizing ideas toward patients and patients' quality of life was significant. By focusing on the interdependence of patients and their caregivers, this study highlights the role of caregivers' stigmatizing attitudes toward patients and patients' perception of caregivers' expressed emotion on patients' quality of life. Psychoeducation and interventions should not only aim to reduce the self-stigma of people with schizophrenia but also their caregivers' stigmatizing ideas toward patients. Family interventions targeted at reducing the EE level of caregivers and patients' perception of caregivers' EE would also benefit the adaptation and quality of life of people with schizophrenia and their caregivers.
