The current study evaluated two web-based programs for eating disorder prevention in high-risk, predominantly ethnic minority women.
Two hundred and seventy-one women with elevated weight concerns were randomized to Internet dissonance-based intervention (DBI-I), Internet cognitive-behavioral intervention (CBI-I), or no intervention (NI). Both interventions consisted of four weekly online sessions. Participants were assessed at pre- and post intervention. Outcome measures included eating pathology, body dissatisfaction, dieting, thin-ideal internalization, and depression.
At postintervention, DBI-I and CBI-I led to greater reductions in body dissatisfaction, thin-ideal internalization, and depression than NI. In addition, CBI-I was effective at reducing dieting and composite eating pathology relative to NI. No outcome differences were found between the active conditions. Moderation analyses suggested that both active conditions were more effective for ethnic minorities than Whites relative to NI.
Results suggest that both DBI-I and CBI-I are effective at reducing eating disorder risk factors in a high-risk, predominantly minority population relative to no intervention.
本研究评估了两个基于网络的项目，用于预防高危且主要为少数族裔女性的饮食失调问题。
271名体重问题较为严重的女性被随机分为基于网络的认知失调干预组（DBI-I）、基于网络的认知行为干预组（CBI-I）或无干预组（NI）。两种干预均包括每周一次的四次在线课程。在干预前后对参与者进行评估。结果测量包括饮食病理学、身体不满、节食、瘦理想内化和抑郁。
干预后，DBI-I组和CBI-I组在身体不满、瘦理想内化和抑郁方面的减少幅度均大于NI组。此外，相对于NI组，CBI-I组在减少节食和综合饮食病理学方面有效。两种积极干预条件之间未发现结果差异。调节分析表明，相对于NI组，两种积极干预条件对少数族裔的效果均比对白人的效果更好。
结果表明，相对于无干预，DBI-I组和CBI-I组在降低高危且主要为少数族裔人群的饮食失调风险因素方面均有效。
