Symptoms of depression and aggressiveness are important antecedents and correlates of suicide ideation and completion in adolescents and adults. Among adolescents, eating disorder symptoms were also found to associate with suicidal behavior. This study was aimed at investigating the role of depression and aggressiveness as mediators in the links between eating disorder symptoms and suicide ideation among adolescents, taking into account age and sex as covariates.
Data from the Conegliano Eating Disorders Survey were used to investigate the role of depression and aggressiveness in the links between eating disorder symptoms and suicide ideation, resorting to a bootstrapped sampling distribution model.
In a mixed male-female sample of 930 adolescents, eating disorder symptoms were positively related to suicide ideation, taking age and sex into account. Depression and aggressiveness acted as full mediators in the links between eating disorder symptoms and suicidality, and virtually abolished any direct influence of eating disorders on suicide ideation.
Because of the cross-sectional nature of this study and the resorting to self-report scales, no firm statement about causal association can be made. However, both suicidal behavior and eating disorder symptoms are a rather widespread occurrence among adolescents, hence the investigation on suicidal tendencies in young people might benefit from the inclusion of measures of eating disorders to prevent the worst outcomes of minor psychological distress.
抑郁症状和攻击性行为是青少年及成年人自杀意念和自杀行为的重要先兆及相关因素。在青少年中,饮食失调症状也被发现与自杀行为有关。本研究旨在探讨抑郁和攻击性行为作为中介变量在青少年饮食失调症状与自杀意念之间联系中的作用,并将年龄和性别作为协变量考虑在内。
使用来自科内利亚诺饮食失调调查的数据,采用自抽样分布模型来研究抑郁和攻击性行为在饮食失调症状与自杀意念之间联系中的作用。
在一个包含930名青少年的男女混合样本中,考虑到年龄和性别因素,饮食失调症状与自杀意念呈正相关。抑郁和攻击性行为在饮食失调症状与自杀倾向之间的联系中起到了完全中介作用,几乎消除了饮食失调对自杀意念的任何直接影响。
由于本研究的横断面性质以及采用的是自我报告量表,因此无法对因果关联做出确凿的陈述。然而,自杀行为和饮食失调症状在青少年中相当普遍,因此对年轻人自杀倾向的调查可能会受益于纳入饮食失调的测量指标,以预防轻微心理困扰带来的最坏结果。
