ABSTRACT

Peer victimization and dating violence victimization frequently co-occur, with 50.4% of adolescents reporting victimization in both social contexts. A possible explanation for the association between these two negative experiences is offered by interpersonal theories of depression. These theories stipulate that depression might not only be caused by relational stressors but may actually also be causing stressful experiences.

Objective

The current study aimed to test if individuals with inherent dispositions to depression-related cognitions and behaviors are more at risk of experiencing relational difficulties, such as peer victimization and dating violence victimization.

Method

This study used a genetically informed design with 806 twins (51.5% girls) to test 1) if at least part of the association between peer victimization in school and dating violence victimization in emerging adulthood can be explained by common underlying heritable factors. Participants provided repeated assessments of their peer victimization in school at ages 13 through 17, their depression symptoms at ages 13 through 19, as well as their victimization in dating relationships at age 19.

Results

A Cholesky decomposition based on structural equation modeling supported the hypotheses. Specifically, the association between peer victimization and dating violence victimization was to a significant extent explained by common underlying genetic vulnerabilities that were associated with depression symptoms. No sex moderation was found.

Conclusions

The findings highlight the importance of addressing early indicators of vulnerability toward depression symptoms to prevent victimization by peers or dating partners.

同伴受害、约会暴力受害与青春期抑郁症之间的联系：一项基因研究

摘要

同伴受害和约会暴力受害经常同时发生，50.4% 的青少年报告在这两种社会背景下都受害。抑郁症的人际理论为这两种负面经历之间的关联提供了可能的解释。这些理论认为，抑郁症可能不仅是由关系压力源引起的，而且实际上也可能导致压力经历。

客观的

目前的研究旨在测试具有抑郁相关认知和行为固有倾向的个体是否更有可能经历人际关系困难，例如同伴受害和约会暴力受害。

方法

这项研究采用基因知情设计，对 806 名双胞胎（51.5% 是女孩）进行测试，以测试 1) 学校同伴受害与成年初期约会暴力受害之间的至少部分关联是否可以通过共同的潜在遗传因素来解释。参与者对 13 至 17 岁时在学校的同伴受害情况、13 至 19 岁时的抑郁症状以及 19 岁时在约会关系中受害情况进行了反复评估。

结果

基于结构方程模型的 Cholesky 分解支持了这些假设。具体而言，同伴受害与约会暴力受害之间的关联在很大程度上可以通过与抑郁症状相关的共同潜在遗传脆弱性来解释。没有发现性节制。

结论

研究结果强调了解决抑郁症状脆弱性的早期指标的重要性，以防止同伴或约会伙伴受害。
