Childhood trauma is associated with onset of symptoms, functioning and cognition in patients with schizophrenia.

Introduction: Childhood trauma (CT) is known to be a vulnerability factor for schizophrenia, but the specific impacts of different trauma subtypes on the prognosis of these patients remains unclear.

Objective: To assess the relationships between the occurrence of overall CT and its subtypes with factors with known prognostic impact on schizophrenia, such as age at onset of symptoms, global functioning, and cognitive impairment in a sample of Brazilian patients.

Methods: One hundred and five stable patients diagnosed with schizophrenia according to DSM-5 criteria were evaluated using the Independent Living Skills Survey (ILSS; self-report global functioning), Schizophrenia Cognition Rating Scale (SCoRS; subjective cognitive impairment), and Childhood Trauma Questionnaire scales (CTQ; perceived overall CT, emotional neglect, physical neglect, physical abuse, and emotional and sexual abuse).
