Disordered eating behaviors, including frequent dieting, unhealthy weight control behaviors (e.g., vomiting and skipping meals for weight loss) and binge eating are prevalent among adolescents. While negative, conflict-ridden family environments have long been implicated as problematic and a contributing factor to the development of disordered eating, few studies have examined the influence of marital conflict exposure in childhood to understand the development of these behaviors in adolescence. The current study investigates the impact of marital conflict, children's emotional insecurity about the marital relationship, and disordered eating behaviors in early adolescence in a prospective, longitudinal study of a community sample of 236 families in Midwest and Northeast regions of the U.S. Full structural mediation analyses utilizing robust latent constructs of marital conflict and emotional insecurity about the marital relationship, support children's emotional insecurity as an explanatory mechanism for the influence of marital conflict on adolescent disordered eating behaviors. Findings are discussed with important implications for the long-term impact of marital conflict and the development of disordered eating in adolescence.
饮食失调行为,包括频繁节食、不健康的体重控制行为(如为减肥而呕吐和不吃饭)以及暴饮暴食,在青少年中很普遍。长期以来,负面且充满冲突的家庭环境一直被认为是有问题的,并且是饮食失调发展的一个促成因素,但很少有研究探讨童年时期暴露于婚姻冲突对理解这些行为在青春期发展的影响。本研究在美国中西部和东北部地区对236个家庭的社区样本进行了一项前瞻性纵向研究,调查了婚姻冲突、儿童对婚姻关系的情感不安全感以及青春期早期的饮食失调行为之间的影响。利用婚姻冲突和对婚姻关系的情感不安全感的稳健潜在结构进行的全结构中介分析,支持将儿童的情感不安全感作为婚姻冲突对青少年饮食失调行为影响的一种解释机制。讨论了研究结果对婚姻冲突的长期影响以及青春期饮食失调发展的重要意义。
