More than words: The association of childhood emotional abuse and suicidal behavior.

All types of abuse and neglect have been associated with suicide attempts. However, the association between the level of each type of childhood trauma and suicidal behavior severity (including the progression from ideation to attempts), adjusting for their co-occurrence, is not yet clear. We used a cross-sectional web-based survey collected from the Brazilian Internet Study on Temperament and Psychopathology (BRAINSTEP) to investigate the isolated effects of each type of childhood trauma on suicidal behavior severity. The sample consisted of 71,429 self-selected volunteers assessed with the Childhood Trauma Questionnaire (CTQ) and the following key question: "Have you ever thought about or attempted to kill yourself?" (Suicidal Behavior Questionnaire, SBQ-17). After adjusting for demographic variables, and childhood trauma subtypes, severe emotional abuse (EA) was associated with suicidal ideation and attempts, mainly for serious suicide attempts (OR, 22.71; 95% CI, 2.32-222.05). We found associations of smaller magnitude for severe emotional neglect (EN) with serious suicide attempts, and for severe physical neglect (PN) and sexual abuse (SA) with attempts without really meaning to die. No meaningful trend for physical abuse (PA) was found. Using as reference group ideators, EA was associated with serious suicide attempts, with a peak at the 95th percentile (OR, 4.39; 95% CI, 2.04-9.41). We found associations of smaller magnitude for PN and SA, and no meaningful trend for EN and PA. Suicidal behavior was strongly associated with emotional abuse in childhood, even when compared with ideators, suggesting that it is a relevant factor for the progression from ideation to attempts.

Prevalence of childhood trauma and correlations between childhood trauma, suicidal ideation, and social support in patients with depression, bipolar disorder, and schizophrenia in southern China.

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. 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. 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. 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. 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.

Childhood trauma and suicide risk in a sample of young individuals aged 14-35 years in southern Brazil.

Suicide is among the main causes of death of people aged between 15 and 44 years old. Childhood trauma is an important risk factor for suicide. Hence, the objective of this study was to verify the relationship between childhood trauma and current suicide risk (suicidal behavior and ideation) in individuals aged 14-35 years, in the city of Pelotas, Brazil. This is a cross-sectional, population-based study. Sample selection was performed by clusters. Suicide risk was evaluated using the Mini International Neuropsychiatric Interview (MINI) and Childhood trauma was assessed with the Childhood Trauma Questionnaire (CTQ). Moreover, the participants responded to a questionnaire concerning socioeconomic status, work, and substance use. The sample was composed of 1,380 individuals. The prevalence of suicide risk was 11.5%. The prevalence figures of childhood trauma were 15.2% (emotional neglect), 13.5% (physical neglect), 7.6% (sexual abuse), 10.1% (physical abuse), and 13.8% (emotional abuse). Suicide risk was associated (p<.001) with gender, work, alcohol abuse, tobacco use, and all types of childhood trauma. The odds of suicide risk were higher in women (OR=1.8), people who were not currently working (OR=2.3), individuals who presented alcohol abuse (OR=2.6), and among tobacco smokers (OR=3.4). Moreover, suicide risk was increased in all types of trauma: emotional neglect (OR=3.7), physical neglect (OR=2.8), sexual abuse (OR=3.4), physical abuse (OR=3.1), and emotional abuse (OR=6.6). Thus, preventing early trauma may reduce suicide risk in young individuals.
