Interrelationships Among Childhood Trauma, Insecure Attachment, Dissociation, Negative Schemas and Psychosis...

Area of Science:

• Psychiatry and Psychology
• Network Analysis in Mental Health

Background:

• Childhood trauma is a known risk factor for psychosis.
• Insecure attachment, dissociation, and negative schemas are identified mediating factors.
• Network analysis provides a framework for understanding complex relationships between trauma, vulnerability factors, and psychosis symptoms.

Purpose of the Study:

• To examine the network structures connecting childhood trauma, insecure attachment, dissociation, negative schemas, and psychosis symptoms.
• To identify central and strongly connected variables within these networks.
• To compare network structures between individuals with and without a psychosis diagnosis.

Main Methods:

• Analysis of cross-sectional, self-report data from an online survey (N=609).
• Utilized Pairwise Markov Random Field (PMRF) networks and strength centrality indices.
• Employed a network comparison test (NCT) to evaluate structural differences between subgroups.

Main Results:

• Bizarre experiences strongly connected with other positive psychosis symptoms.
• Negative-self schemas and paranoia formed a cluster with negative-other schemas, avolition, and insecure attachment.
• Depersonalisation-derealisation showed strong connectivity with hallucinations; no significant structural differences were found between psychosis groups.

Conclusions:

• Targeting negative-self schemas and paranoia is recommended for reducing cross-construct network connectivity and prioritizing treatment.
• Interventions for detachment-related dissociation may help alleviate hallucinations.
• Longitudinal studies are necessary to confirm findings and investigate causal pathways.
