Schizotypal dimensions by migrant status in the general population: An exploratory study

Area of Science:

• Psychiatry and Mental Health
• Sociology
• Public Health

Background:

• Migrant status and ethnic minority background are known risk factors for psychosis.
• The association between these factors and subclinical psychosis requires further investigation.

Purpose of the Study:

• To investigate the association between migrant status, ethnicity, and dimensions of psychosis (positive, negative, disorganized) in general population samples.
• To examine if migrant status and ethnicity predict self-reported schizotypal traits.

Main Methods:

• Two general population samples totaling 460 subjects were analyzed.
• Self-reported positive, negative, and disorganized dimensions of psychosis were measured using the Schizotypal Personality Questionnaire - Brief (SPQ-B).
• Migrant status (first and second-generation) and ethnicity were assessed as predictors.

Main Results:

• First and second-generation migrants, and specific ethnic minority groups (North African, French overseas), showed higher scores in the negative dimension of psychosis compared to the reference population.
• The findings indicate a significant association between negative schizotypal traits and migrant/ethnic minority status.

Conclusions:

• The study underscores the need to understand the mechanisms linking negative schizotypal traits to migrant and ethnic minority status.
• These findings support the psychosis continuum theory, suggesting a link from subclinical traits to psychotic disorders.
• Tailored policies and interventions are necessary to improve mental health and prevent psychosis in these vulnerable subgroups.
