Introduction: Among the environmental factors recognized to convey an increased risk for psychosis, childhood trauma (CT) holds a prominent position. CT is a generic term encompassing experiences of sexual, physical and emotional abuse, and neglect during childhood and adolescence. Due to the fact that CT in adult patients with psychosis has been mainly assessed through retrospective reports, concerns have been raised about the reliability and validity of these data. Objectives: We sought to explore the short-term reliability of retrospective CT reports in a group of patients with schizophrenia-spectrum psychosis (SSP). Methods: We assessed 63 SSP patients on two different early adversity self-report measures to establish concurrent validity by confirming the similarity of CT ratings; and on two separate occasions (T1: inpatient status; T2: outpatient status, three months after initial testing) to establish test-retest reliability by confirming the temporal stability of abuse and neglect reporting. Early adversity was measured with the Childhood Experience of Care and Abuse Questionnaire (CECA.Q), and the Parental Bonding Instrument (PBI). Results: High concurrent validity was detected between CECA.Q antipathy scales and PBI care and protection scales; and between CECA.Q neglect scales and PBI care scales. High test-retest reliability was confirmed for all CECA.Q and PBI scales. Conclusions: Our findings indicate that retrospective CT reports are a reasonably reliable and valid means of assessing early experiences of abuse and neglect in SSP patients. However, additional provisions are required for corroborating these reports through other sources and removing the effect of confounding variables, such as caveats of autobiographical memory, desirability bias and psychopathology.
