Body dissatisfaction has been related to Body Image Disorders (BIDs) such as Eating Disorders (EDs) and Body Dysmorphic Disorder (BDD). This study investigates the efficacy of a mHealth app in reducing body dissatisfaction, BDD/ED symptoms and related features. Ninety-five women who were identified as high-risk of developing BIDs (using the Structured Clinical Interview for DSM-5) were randomized into: immediate-use App (iApp group; n = 47) and delayed-use App (dApp group; n = 48). The iApp group started using the app at baseline for 16 days (T1). The dApp group started using the app at T1 for 16 days. Participants completed questionnaires at baseline (T0), 16 days from baseline (T1), and 32 days from baseline (T2). Repeated measure Multivariate Analysis of Variance (MANOVA) showed Group (iApp vs. dApp) × Time (T0 vs. T1) interactions indicating decrease in BDD symptoms and body dissatisfaction related to EDs in the iApp group at T1. The Reliable Change Index indicated changes on extreme body dissatisfaction/BDD symptoms for 34.74% of participants. Although preliminary, these findings highlight that a mHeatlh app might reduce BDD symptoms and body dissatisfaction related to EDs in women at high-risk for BIDs. Effects on ED symptoms and associated features seem more limited.
身体不满与身体意象障碍（BID）有关，如饮食障碍（ED）和躯体变形障碍（BDD）。本研究调查了移动健康应用程序在降低身体不满、BDD/ED 症状和相关特征方面的疗效。95 名被确定为患有 BID 高风险的女性（使用 DSM-5 结构临床访谈）被随机分为：立即使用应用程序（iApp 组；n=47）和延迟使用应用程序（dApp 组；n=48）。iApp 组在基线时开始使用该应用程序 16 天（T1）。dApp 组在 T1 时开始使用该应用程序 16 天。参与者在基线（T0）、基线后 16 天（T1）和基线后 32 天（T2）完成问卷。重复测量多元方差分析（MANOVA）显示，组（iApp 与 dApp）×时间（T0 与 T1）的交互作用表明，iApp 组在 T1 时 BDD 症状和与 ED 相关的身体不满减少。可靠变化指数表明，34.74%的参与者在极端身体不满/BDD 症状方面发生了变化。尽管初步结果，但这些发现强调了移动健康应用程序可能会降低患有 BID 高风险的女性的 BDD 症状和与 ED 相关的身体不满。对 ED 症状和相关特征的影响似乎更为有限。
