Schizotypal Traits, Psychopathology, and Reflective Functioning Impairments During Adolescence: A Bayesian Network...

Area of Science:

• Psychiatry
• Developmental Psychology
• Network Science

Background:

• Bayesian networks offer new models for understanding psychosis risk.
• Schizotypal traits, psychopathology, and reflective functioning (RF) impairments are key areas of interest.
• Adolescence is a critical period for exploring these relationships.

Purpose of the Study:

• To investigate the causal relationships between schizotypal dimensions, psychopathology, and RF impairments in non-clinical adolescents.
• To utilize a directed acyclic graph (DAG) to model these putative causal links.
• To contribute to a richer understanding of psychosis risk.

Main Methods:

• A cross-sectional survey of 1476 adolescents from the general population.
• Utilized the Oviedo Schizotypy Assessment Questionnaire-Revised, Strengths and Difficulties Questionnaire, and Reflective Functioning Questionnaire (RFQ).
• Employed probabilistic directed acyclic graph (DAG) modeling.

Main Results:

• Schizotypal traits showed positive associations with psychopathology and hypomentalizing (impaired RF).
• Identified putative causal relationships between specific schizotypal dimensions (Reality distortion, Social disorganization, Anhedonia) and outcomes.
• DAG analysis indicated that schizotypal dimensions influence psychopathology and RF impairments.

Conclusions:

• Adolescent schizotypal traits connect to mental health problems and RF impairments through distinct pathways.
• Probabilistic DAGs enhance causal inference regarding psychosis risk.
• This study unravels complex causal chains relevant to adolescent mental health and psychosis risk.
