The purpose of this experiment was to provide an empirical comparison of two dissonance-based eating disorder prevention paradigms and a no-treatment control condition. Asymptomatic and symptomatic participants (N = 155) were randomly assigned to one of three experimental conditions: high level dissonance, low level dissonance, or no-treatment control. Group x symptomatic status interactions, main effects, and pairwise comparisons were examined to assess differences in eating disorder attitudes and behaviors at postintervention and 4-week follow-up. Participants in the high level condition displayed fewer eating disorder attitudes and behaviors compared to participants in the low level condition at postintervention. Eating disorder attitudes and behaviors were not significantly lower among participants in either intervention condition compared to no-treatment control participants.
本实验的目的是对两种基于认知失调的饮食失调预防范式和一种无治疗对照条件进行实证比较。无症状和有症状的参与者（N = 155）被随机分配到三个实验条件之一：高认知失调、低认知失调或无治疗对照。检验组x症状状态交互作用、主效应和两两比较，以评估干预后和4周随访时饮食失调态度和行为的差异。在干预后，高认知失调条件下的参与者与低认知失调条件下的参与者相比，表现出更少的饮食失调态度和行为。与无治疗对照参与者相比，两种干预条件下的参与者的饮食失调态度和行为均未显著降低。
