Depression in caregivers of patients with schizophrenia: a scoping review.

PURPOSE: Caregivers play a vitally important role in the lives of people with schizophrenia. However, their mental health can often be overlooked. In recent years, with increasing attention to mental health and wellness, common mental illness such as depression in caregivers of people with schizophrenia has received renewed attention. The purpose of this review was to consolidate and synthesize recent literature on (1) the prevalence of depression in caregivers of people with schizophrenia, (2) factors associated with depression in caregivers of people with schizophrenia, and (3) interventions that target depression in caregivers of people with schizophrenia.

METHODS: A systematic search focusing on literature published between 2010 and 2022 was done to retrieve relevant articles from the following databases: Ovid MEDLINE, Ovid EMBASE, and Ovid Psych INFO.

RESULTS: Twenty-four studies met inclusion criteria and were included in the review. Nine evaluated the prevalence of depression, 18 evaluated factors associated with depression in caregivers, and 6 examined interventions targeting depression. The prevalence of depression and depressive symptoms in samples of caregivers ranged between 12 and 40% across the studies. Females, especially mothers of people with schizophrenia, were more likely to experience depression, followed by younger caregivers. Several factors, including gender, interpersonal relationships, social support, stigma, literacy, and financial constraints, were identified as factors associated with depression in caregivers. Several interventions like yoga, emotional training, and psychoeducation were evaluated, and they showed a significant reduction in the level of depression and depressive symptoms experienced by the caregiver population.

CONCLUSIONS: Depression in caregivers in this clinical population may be widespread and warrants further study. There are promising interventions that can target depression in caregivers. Well-designed longitudinal studies may help identify caregivers at risk of developing depression and further inform targets for intervention.
