The history of multiple adverse childhood experiences in patients with schizophrenia is associated with more severe symptomatology and suicidal behavior with gender-specific characteristics.

The current study aims to compare the prevalence of adverse childhood experiences (ACEs) between patients with schizophrenia and non-psychiatric control group, and to analyze the association of having suffered multiple ACEs with clinical symptoms of schizophrenia and suicidal behavior. A multicenter, cross-sectional study was conducted across three facilities in Buenos Aires, Argentina. One-hundred patients with schizophrenia and 50 healthy subjects were assessed with the Adverse Childhood Experiences questionnaire (ACE-Q), the Positive and Negative Syndrome Scale (PANSS), and the Columbia-Suicide Severity Rating Scale (C-SSRS). We observed that the prevalence of at least one ACE in schizophrenic patients was almost double in comparison with the non-psychiatric control group. Multiple ACEs were associated with persistent auditory hallucinations and lower negative symptoms in both sexes. Higher frequency of death ideation and a higher number of suicide attempts were reported among women. The strength of this study is the possibility of comparing the presence of ACEs between schizophrenic patients and non-psychiatric control using the same questionnaire in an under-reported sample of low socio-economic patients assisted in public hospitals. A limitation is that the history of ACEs relied on the retrospective assessment of childhood experiences, and adults could over-report ACEs because of recall bias.

Adverse Childhood Experiences among Men with Schizophrenia.

Individuals who suffered traumatic events or adverse experiences during their childhood have an increased risk of developing during adulthood physical problems, aggressive behavior, and psychiatric disorders, such as schizophrenia. Patients diagnosed with schizophrenia have higher rates of traumatic experiences during childhood than the general population, and those who suffered multiple traumatic events have an increased risk of disease relapse. The current study aims to determine the prevalence of different types of adverse experiences during childhood among a male patient sample with schizophrenia. An Observational descriptive cross-sectional study was conducted at Jose T. Borda Hospital, in Buenos Aires, Argentina. Participants included 51 male patients between the ages of 18 and 63 years with a diagnosis of schizophrenia. Semi-structured interviews were conducted, applying a socio-demographic questionnaire, SCID I and II scales to assess psychiatric diagnosis, and the Adverse Childhood Experiences (ACE) Questionnaire to evaluate the presence of adverse childhood experiences. Statistical analyses were conducted using SPSS 22 software. We observed that 94% of participants had experienced at least one adverse childhood experience. Most (63%) suffered from 4 or more disruptive child events. A high prevalence of family history of mental illness was found, also emotional abuse and neglect. Most traumatic events occurred within the family group. It was found a moderately significant relationship between patients who suffered adverse events and the presence of auditory hallucinations.
