    Abstract:
    BACKGROUND: Childhood trauma has long-term adverse effects on physical and psychological health. Previous studies demonstrated that suicide and mental disorders were related to childhood trauma. In China, there is insufficient research available on childhood trauma in patients with mental disorders. METHODS: Outpatients were recruited from a psychiatric hospital in southern China, and controls were recruited from local communities. The demographic questionnaire, the Childhood Trauma Questionnaire-Short Form (CTQ-SF), and the Social Support Rating Scale (SSRS) were completed by all participants, and the Self-rating Idea of Suicide Scale (SIOSS) were completed only by patients. Prevalence rates of childhood trauma were calculated. Kruskal-Wallis test and Dunnett test were used to compare CTQ-SF and SSRS scores between groups. Logistic regression was used to control demographic characteristics and examine relationships between diagnosis and CTQ-SF and SSRS scores. Spearman's rank correlation test was conducted to analyze relationships between suicidal ideation and childhood trauma and suicidal ideation and social support. RESULTS: The final sample comprised 229 patients with depression, 102 patients with bipolar, 216 patient with schizophrenia, and 132 healthy controls. In our sample, 55.5% of the patients with depression, 61.8% of the patients with bipolar disorder, 47.2% of the patients with schizophrenia, and 20.5% of the healthy people reported at least one type of trauma. In patient groups, physical neglect (PN) and emotional neglect (EN) were most reported, and sexual abuse (SA) and physical abuse (PA) were least reported. CTQ-SF and SSRS total scores, and most of their subscale scores in patient groups were significantly different from the control group. After controlling demographic characteristics, mental disorders were associated with higher CTQ-SF scores and lower SSRS scores. CTQ-SF scores and number of trauma types were positively correlated with the SIOSS score. Negative correlations existed between SSRS scores and the SIOSS score. LIMITATIONS: Our sample may not be sufficiently representative. Some results might have been interfered by demographic characteristics. The SIOSS was not completed by controls. Data from self-report scales were not sufficiently objective. CONCLUSIONS: In southern China, childhood trauma is more severe and more prevalent in patients with mental disorders (depression, bipolar disorder and schizophrenia) than healthy people. Among patients with mental disorders in southern China, suicidal ideation is associated with childhood trauma and poor social support.
