Body image disturbance (BID) is common among women, characterized by persistent and distressing appearance dissatisfaction, and linked with eating disorders. Although effective, cognitive behavioral therapy (CBT) delivered by trained professionals is not easily accessible. This randomized trial evaluated the effects of a CBT-based mobile application designed to increase resilience to body image triggers and reduce BID symptoms.
A non-clinical sample of women (N = 90; M = 23.52) was randomized to use the mobile application for approximately 4 min of daily exercises for two weeks or to a control condition. Body image was measured at baseline, immediately after two weeks of mobile application use, and at 1-month follow-up. To examine whether using the application was associated with increased resilience to common BID triggers, participants completed an Instagram exposure resilience task upon completion and at 1-month follow-up.
Relative to those in the control condition, participants who used the application demonstrated increased resiliency and reduced BID symptoms. Theses effects were medium-to-large and were maintained at 1-month follow-up.
These results underscore the potential usefulness of brief, low-intensity, portable interventions in reducing BID symptoms and in increasing resilience to thin-ideal body messages often portrayed on social media.
身体形象障碍（BID）在女性中很常见，其特征是持续且痛苦的外表不满，并与饮食失调有关。尽管认知行为疗法（CBT）由训练有素的专业人员实施时有效，但并不容易获得。这项随机试验评估了一款基于CBT的移动应用程序的效果，该应用程序旨在增强对身体形象触发因素的恢复力并减轻BID症状。
将一组非临床女性样本（N = 90；M = 23.52）随机分为两组，一组使用该移动应用程序进行为期两周的每日约4分钟的锻炼，另一组作为对照。在基线、使用移动应用程序两周后立即以及1个月随访时测量身体形象。为了检验使用该应用程序是否与对常见BID触发因素的恢复力增强有关，参与者在完成应用程序使用时和1个月随访时完成了一项Instagram曝光恢复力任务。
与对照组相比，使用该应用程序的参与者表现出恢复力增强和BID症状减轻。这些效果为中等到较大，并在1个月随访时得以维持。
这些结果强调了简短、低强度、便携式干预措施在减轻BID症状以及增强对社交媒体上经常描绘的瘦理想身体信息的恢复力方面的潜在有用性。
