Data suggest that depressed affect and dietary restraint are related to disinhibited eating patterns in children and adults. Yet, experimental research has not determined to what extent depressed affect acutely affects eating in the absence of physiological hunger (EAH) in adolescents. In the current between-subjects experimental study, we measured EAH in 182 adolescent (13-17 y) girls (65%) and boys as ad libitum palatable snack food intake after youth ate to satiety from a buffet meal. Just prior to EAH, participants were randomly assigned to view either a sad or neutral film clip. Dietary restraint was measured with the Eating Disorder Examination. Adolescents who viewed the sad film clip reported small but significant increases in state depressed affect relative to adolescents who viewed the neutral film clip (p < .001). Yet, there was no main effect of film condition on EAH (p = .26). Instead, dietary restraint predicted greater EAH among girls, but not boys (p < .001). These findings provide evidence that adolescent girls' propensity to report restrained eating is associated with their greater disinhibited eating in the laboratory. Additional experimental research, perhaps utilizing a more potent laboratory stressor and manipulating both affective state and dietary restraint, is required to elucidate how state affect may interact with dietary restraint to influence EAH during adolescence.
数据表明，情绪低落和饮食节制与儿童及成人的无节制饮食模式有关。然而，实验研究尚未确定情绪低落在青少年没有生理性饥饿（EAH）的情况下对进食的急性影响程度。在当前的组间实验研究中，我们测量了182名青少年（13 - 17岁）女孩（65%）和男孩的EAH，测量方法是让青少年在自助餐吃到饱腹感后随意摄入美味的零食。在测量EAH之前，参与者被随机分配观看悲伤或者中性的电影片段。饮食节制通过饮食失调检查来测量。与观看中性电影片段的青少年相比，观看悲伤电影片段的青少年报告称其状态性情绪低落有小幅但显著的增加（p < 0.001）。然而，电影片段条件对EAH没有主效应（p = 0.26）。相反，饮食节制预示着女孩（而非男孩）会有更多的EAH（p < 0.001）。这些发现提供了证据，表明青少年女孩报告有节制饮食的倾向与其在实验室中更多的无节制饮食有关。需要更多的实验研究，或许可以利用更有效的实验室应激源并同时操纵情绪状态和饮食节制，以阐明情绪状态如何与饮食节制相互作用来影响青少年时期的EAH。
