OBJECTIVE Based on previous findings that suicidal ideation (SI) and behavior (SB) arose in depressed preschoolers and showed stability into school age, we sought to investigate whether unique clinical and psychosocial correlates of SI/SB and nonsuicidal self-injurious behaviors (NSSI) could be identified in young children recuited into a depression treatment study and healthy controls. METHOD Data from 288 children 3.0 to 6.11 years of age who were recruited for participation in a psychotherapy treatment study of depression and 26 healthy control subjects (total N = 314) were used. At baseline, subjects received a comprehensive assessment of psychopathology and suicidal ideation/suicidal behavior. Multinominal logistic regressions were conducted comparing those with no SI/SB/NSSI to those with SI/SB or NSSI. Those with SI/SB who also had NSSI were placed in the SI/SB group. RESULTS In this sample of young children, the rates of NSSI, SI, and SB were 21.3%, 19.1%, and 3.5% respectively. Children with SI/SB or NSSI experienced a greater frequency of violent life events than children with no SI/SB/NSSI. Children with SI/SB had significantly more preoccupation with death compared to subjects with NSSI and subjects with no SI/SB/NSSI. Children with SI/SB had more vegetative signs of depression and greater depression severity, and those with NSSI were more irritable with higher depression severity than those with no SI/SB/NSSI. CONCLUSION Distinct characteristics of SI/SB and NSSI in early childhood were identified, informing high risk subgroups. Findings suggest that clinicians should be aware of the potential for SI/SB and/or NSSI in young children and should directly address these symptoms in clinical interviews.

具有自杀意念，行为和非自杀性自残行为的幼儿的临床和社会心理特征。

目的基于先前的发现，抑郁抑郁的学龄前儿童会出现自杀意念（SI）和行为（SB），并且在入学年龄之前表现出稳定性，我们试图调查SI / SB与非自杀性自残行为（NSSI）的独特临床和心理社会相关性可以在接受抑郁症治疗研究和健康对照的幼儿中确定。方法使用了288名3.0至6.11岁的儿童作为研究对象，他们参与了抑郁症的心理治疗研究，并使用了26名健康对照者（总N = 314）。在基线时，受试者接受了心理病理学和自杀意念/自杀行为的综合评估。进行了多项logistic回归，将没有SI / SB / NSSI的人与有SI / SB或NSSI的人进行了比较。SI / SB组同时也有NSSI的患者被分为SI / SB组。结果在这个年幼的儿童样本中，NSSI，SI和SB的发生率分别为21.3％，19.1％和3.5％。与没有SI / SB / NSSI的儿童相比，患有SI / SB或NSSI的儿童经历暴力生活事件的频率更高。与患有NSSI的受试者和没有SI / SB / NSSI的受试者相比，患有SI / SB的儿童对死亡的关注更大。SI / SB患儿的抑郁症有更多的植物体征，抑郁严重程度更高，而NSSI患儿比没有SI / SB / NSSI患儿的抑郁症严重程度更高。结论确定了儿童早期SI / SB和NSSI的明显特征，为高危亚组提供了信息。研究结果表明，临床医生应意识到幼儿中SI / SB和/或NSSI的可能性，并应在临床访谈中直接解决这些症状。临床试验注册信息PCIT-ED治疗学前抑郁症的随机对照试验。https://clinicaltrials.gov/; NCT02076425。
