This study investigated the dietary restraint and depression pathway to loss of control over eating among a sample of overweight youngsters based on the assumptions of the extended cognitive behavioural theory for bulimia nervosa. The children's version of the eating disorder examination interview and the children's depression inventory were administered to 350 overweight youngsters (with a mean age of 13.30 years old). Structural equation modelling indicated that the over-evaluation of eating, weight and shape was significantly associated with dietary restraint, which in turn was significantly associated with loss of control over eating. Evidence was also found for a direct pathway between depressive symptoms and loss of control over eating. It can be concluded that in general, the main components to maintain the bulimic cycle in eating disordered patients operate in a similar way to maintain loss of control over eating in overweight youngsters.
本研究基于神经性贪食症的扩展认知行为理论假设，探讨了超重青少年中饮食抑制与抑郁对失控性进食的作用途径。采用饮食障碍检查访谈儿童版和儿童抑郁量表对 350 名超重青少年（平均年龄 13.30 岁）进行了测试。结构方程模型表明，对饮食、体重和体型的过度评价与饮食抑制显著相关，而饮食抑制又与失控性进食显著相关。此外，还发现抑郁症状与失控性进食之间存在直接途径。总的来说，可以得出结论，在饮食障碍患者中维持贪食循环的主要因素与维持超重青少年的失控性进食以相似的方式起作用。
