This study examined whether self-reported and observationally measured parental behaviours were associated with disordered eating, and investigated possible moderation by a serotonin-transporter polymorphism (5-HTTLPR). Study 1 included 650 adolescents from the Australian Temperament Project who completed the Eating Disorder Inventory-2 Drive for Thinness and Bulimia scales at 15/16 years and were genotyped for 5-HTTLPR. Parents completed an Australian Temperament Project-devised measure of parental warmth and harsh punishment. Study 2 included a subgroup of 304 participants who also engaged in a video-recorded family interaction, with observed parental warmth and hostility coded by the Iowa Family Interaction Rating Scale. Greater self-reported parental warmth was associated with lower bulimia scores. Conversely, observationally measured parental warmth was associated with lower drive for thinness, but not bulimia. Self-reported parental harsh punishment was associated with bulimia only, with observed parental hostility associated with neither outcome. 5-HTTLPR genotype did not moderate the relationship between parent behaviours and adolescent disordered eating.

本研究旨在探讨父母的自我报告行为和观察到的行为是否与饮食失调有关，并探讨 5-羟色胺转运蛋白基因多态性（5-HTTLPR）是否存在调节作用。研究 1 纳入了 650 名来自澳大利亚气质项目的青少年，他们在 15/16 岁时完成了饮食失调问卷-2 中的“追求苗条”和“贪食”量表，并进行了 5-HTTLPR 基因分型。父母完成了澳大利亚气质项目设计的父母温暖和严厉惩罚量表。研究 2 包括了 304 名参与者的一个亚组，他们还参与了一个视频记录的家庭互动，观察到的父母温暖和敌意由爱荷华家庭互动评分量表进行编码。自我报告的父母温暖与较低的贪食评分相关。相反，观察到的父母温暖与较低的追求苗条有关，但与贪食无关。自我报告的父母严厉惩罚仅与贪食有关，观察到的父母敌意与这两个结果均无关。5-HTTLPR 基因型不能调节父母行为与青少年饮食失调之间的关系。版权所有 © 2017 约翰威利父子公司和饮食失调协会。
