Depression mediates the link between positive symptoms like delusions and hallucinations and social isolation in early psychosis. Addressing psychosis and depression is key to improving social connection and mental health outcomes.
Area of Science:
- Psychiatry and Mental Health
- Clinical Psychology
Background:
- Social isolation is prevalent in schizophrenia spectrum and other psychotic disorders.
- It correlates with adverse mental health outcomes, including depression and negative symptoms.
- The role of social isolation in positive symptoms is less understood.
Purpose of the Study:
- To investigate depression as a mediator between positive symptoms (hallucinations, delusions) and social isolation.
- To analyze these relationships in individuals experiencing a first episode of psychosis.
Main Methods:
- Utilized data from the Recovery After an Initial Schizophrenia Episode (RAISE) project.
- Included 404 participants aged 15-40 with a first episode of psychosis.
- Employed structural equation modeling (SEM) using Mplus (Version 8) for data analysis.
Main Results:
- Delusions and hallucinations were directly associated with increased depression.
- Both delusions and depression were directly linked to greater social isolation.
- Depression significantly mediated the relationship between positive symptoms and social isolation.
Conclusions:
- Depression plays a crucial mediating role in how positive symptoms contribute to social isolation.
- Treatment should target psychosis symptoms, depression, social skills, and support networks.
- Addressing stigma is vital for mitigating social isolation and improving mental health in this population.
