Identifying victimisation profiles in people with psychosis and a history of childhood trauma: a latent class analysis

Abstract

Background: People with psychosis experience higher rates of childhood victimisation compared to the general population, which may impact on mental health and recovery. This study aimed to identify childhood victimisation profiles in a clinical sample to inform recommendations for routine care.

Methods: Participants were 146 adults (ages 19-65 years; M = 42.2) with schizophrenia-spectrum diagnoses reporting trauma. Childhood trauma was assessed using two retrospective measures, and a latent class analysis (LCA) was performed on four trauma types (sexual abuse, emotional abuse, physical abuse and neglect). Multinomial logistic regression investigated demographic differences between the classes.

Results: Four distinct childhood trauma classes were identified: Emotional abuse/neglect (n = 29); physical abuse (n = 14); sexual abuse (n = 19); and poly-victimisation (n = 84). There were no differences between the classes in terms of age, ethnicity, relationship status, education or current employment (relative risk (RR) = 0.85-1.27, p > 0.05). Participants in the poly-victimisation class were significantly more likely to be female (RR = 0.22-0.28, p < 0.04).

Discussion: Adults with psychosis, particularly females, are likely to report poly-victimisation in childhood. This highlights the need to comprehensively but concisely assess experiences of abuse and neglect in clinical care, in line with trauma-informed approaches.
