Childhood trauma is a well-established risk factor for psychosis. Beyond its global effect on symptom severity and prognosis, emerging evidence suggests that distinct trauma subtypes may be linked to specific psychotic symptoms.
Objectives
This study examined the associations between childhood maltreatment and individual symptom dimensions in first-episode psychosis (FEP).
Methods
We recruited 65 outpatients with FEP stabilized for at least three months. Childhood trauma was assessed with the Childhood Trauma Questionnaire–Short Form (CTQ-SF), and symptoms with the Positive and Negative Syndrome Scale (PANSS). Correlations were explored between CTQ subscales and PANSS items. A p-value < 0.05 was considered statistically significant.
Results
The total CTQ score correlated positively with delusions (p=0.017, r=0.307), suspiciousness/persecution (p=0.025, r=0.289), unusual thought content (p=0.002, r=0.394), poor judgment and lack of insight (p=0.049, r=0.256), and poor impulse control (p=0.033, r=0.276). The significant correlations between CTQ subscales ans PANSS items are summarized in Table 1.
