ABSTRACT

Childhood trauma in schizophrenia (SCZ) is associated with aberrant neurobiological downstream effects and cognitive deficits that markedly hinder patient outcome and functioning. However, the relationship between specific forms of childhood abuse and the tendency for certain personality traits in patients with SCZ has not been comprehensively studied yet. We recruited 374 SCZ patients and screened for history of physical abuse (PA), emotional abuse (EA), sexual abuse (SA), physical neglect (PN) and emotional neglect (EN) using the Childhood Trauma Questionnaire and measured personality traits using the NEO Five-Factor inventory. Using CTQ cut-off scores, the prevalence of EA, PA, SA, EN and PN was 60.7%, 42.0%, 37.7%, 64.2% and 54.3% respectively. Exposure to any form of childhood abuse was associated with increased neuroticism. Exposure to EA, SA, PN and EN was correlated with decreased agreeableness and conscientiousness scores. PN, EN and PA exposure was associated with decreased openness while EA, PN and EN exposure was associated with decreased extraversion. Furthermore, a positive correlation was found between all forms of childhood abuse and trait neuroticism whereas negative correlations were found between certain forms of childhood abuse and all other personality traits. Exposure to specific forms of childhood abuse was associated with specific personality traits in patients with SCZ.
