Conduct a randomized treatment trial to test whether healthy dieting maintains bulimic symptoms or effectively reduces this eating disturbance.
Female participants (n=85) with full- and sub-threshold bulimia nervosa were randomly assigned to a 6-session healthy dieting intervention or waitlist condition and assessed through 3-month follow-up.
Relative to control participants, intervention participants showed modest weight loss during treatment and demonstrated significant improvements in bulimic symptoms that persisted through follow-up.
These preliminary results suggest that this intervention shows potential for the treatment of bulimia nervosa and may be worthy of future refinement and evaluation. Results also provide experimental evidence that dieting behaviors do not maintain bulimia nervosa, suggesting the need to reconsider maintenance models for this eating disorder.
开展一项随机治疗试验,以检验健康饮食是会维持暴食症状还是能有效减轻这种饮食紊乱状况。
将患有完全型和亚阈值神经性贪食症的女性参与者(n = 85)随机分配至接受为期6节的健康饮食干预组或等候名单组,并通过3个月的随访进行评估。
与对照组参与者相比,干预组参与者在治疗期间体重有适度减轻,且暴食症状有显著改善,这种改善在随访期间持续存在。
这些初步结果表明,该干预措施对神经性贪食症的治疗具有潜力,可能值得未来进一步完善和评估。研究结果还提供了实验证据,表明节食行为不会维持神经性贪食症,这表明有必要重新考虑这种饮食失调症的维持模型。
