Ecologically Valid Disordered Eating Prevention Program for At-Risk College Women

描述（由申请人提供）：本提案的目的是使用个人数字助理（pda）来整合心理社会评估和干预（基于社会认知理论），为有风险的大学女性预防饮食失调。pda有两种不同的用途：(a)采用生态瞬时评估（EMA）的评估装置；(b)提供干预措施的装置。拟议的工作具有创新性，因为它结合了pda的评估和干预能力。参与者将完成EMA报告，微干预（Mis）将基于并发的EMA反应在pda上进行管理。Mis是在便携式设备上提供的简短治疗扩展。Ml将针对女性最容易对身体形象不满（在初步研究中确定）的三种具体经历（饮食、媒体曝光、负面情绪）。有发生饮食失调风险的本科女性（n=144）将被随机分配到CD- rom干预和EMA报告（EMA+CD）、CD、EMA和微干预（EMA+CD+MI）或仅EMA （EMA）组。所有参与者将完成身体形象不满意、饮食失调和心理健康的基线评估。在接下来的一周内，参与者将在pda上完成每日6次的EMA调查（包括身体形象不满、饮食行为、媒体曝光和情绪项目）。EMA+CD组和EMA+CD+MI组将接受食物、情绪和态度CD- rom干预。一周后，所有参与者将再次收到pda，并完成相同的EMA调查。EMA+CD+MI组也将成为目标。Mis包括提醒使用CD-ROM中学习的技能，并将在调查后立即在PDA上进行，然后在EMA后10至20分钟进行。所有参与者将完成1个月和3个月的饮食失调、身体形象不满和心理健康的随访评估。仅EMA组将在完成3个月的评估后接受CD-ROM干预。如果所有参与者希望寻求额外的护理，他们将获得转诊信息。这项研究的公共卫生意义包括一种方法的创新发展，以提高饮食病理学预防计划（即微干预）的功效。这些预防项目将被证明有助于减少饮食失调的发病率，并对其他治疗和预防策略产生影响，为更广泛的治疗扩展的发展和实施提供信息。

DESCRIPTION (provided by applicant): The aim of this proposal is to use personal digital assistants (PDAs) to integrate psychosocial assessments and interventions (based on Social Cognitive Theory) for disordered eating prevention for at-risk college women. PDAs have been used in two distinct capacities: (a) an assessment device employing Ecological Momentary Assessment (EMA); (b) a device for delivering interventions. The proposed work is innovative because it combines the assessment and intervention capacities of PDAs. Participants will complete EMA reports, and micro-interventions (Mis) will be administered on PDAs based on concurrent EMA responses. Mis are brief treatment extensions delivered on portable devices. The Ml will be targeted to three specific experiences (eating, media exposure, negative mood) when women are most vulnerable to body image dissatisfaction (identified in preliminary research). Undergraduate women at-risk of developing disordered eating (n=144) will be randomly assigned to a CD-ROM intervention and EMA reports (EMA+CD), CD, EMA and micro-interventions (EMA+CD+MI), or EMA only (EMA) groups. All participants will complete baseline assessments of body image dissatisfaction, disordered eating, and psychological well-being. Six times daily for the following 1 week, participants will complete EMA surveys (including body image dissatisfaction, eating behavior, media exposure, and mood items) on PDAs. The EMA+CD and EMA+CD+MI groups will receive the Food, Mood, and Attitude CD-ROM intervention. One week later all participants will receive the PDAs again and complete the same EMA survey. The EMA+CD+MI group will also receive targeted. Mis consist of reminders to use skills learned in the CD-ROM and will be administered on the PDA immediately following the survey, and then 10 to 20 minutes following the EMA. All participants will complete 1- and 3-month follow-up assessments of disordered eating, body image dissatisfaction, and psychological well-being. The EMA only group will receive the CD-ROM intervention after completing the 3-month assessment. All participants will be given referral information if they wish to seek additional care. The public health significance of this research includes the innovative development of a methodology to increase the efficacy of eating pathology prevention programs (i.e., micro-interventions). These prevention programs will prove useful in reducing the incidence of eating disorders and have implications for other treatments and prevention strategies, by informing the development and implementation of treatment extensions more broadly.
