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

描述(由申请人提供)：这项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)，为高危大学女性预防饮食失调。个人数字助理有两种不同的用途：(A)使用生态瞬时评估的评估工具；(B)提供干预措施的工具。拟议的工作具有创新性，因为它结合了个人数字助理的评估和干预能力。参与者将完成EMA报告，并将根据EMA的同时响应在PDA上实施微干预(MI)。MI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的三种具体体验(饮食、媒体曝光、负面情绪)(在初步研究中确定)。有进食障碍风险的大学生女性(n=144)将被随机分配到CD-ROM干预和EMA报告组(EMA+CD)、CD、EMA和微型干预(EMA+CD+MI)或仅EMA(EMA)组。所有参与者将完成对身体形象不满意、饮食紊乱和心理健康的基线评估。在接下来的一周里，参与者每天六次，在PDA上完成EMA调查(包括身体形象不满、饮食行为、媒体接触和情绪项目)。EMA+CD组和EMA+CD+MI组将接受食物、情绪和态度光盘干预。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组也将接受定向治疗。管理信息系统包括提醒使用从光盘中学到的技能，并将在调查结束后立即在PDA上执行，然后在EMA之后10至20分钟执行。所有参与者将完成为期1个月和3个月的饮食紊乱、身体形象不满和心理健康的随访评估。仅EMA组在完成为期3个月的评估后将接受CD-ROM干预。如果所有参与者希望寻求额外的护理，他们将获得转介信息。这项研究的公共卫生意义包括创新开发一种方法学，以提高饮食病理预防计划(即微干预)的有效性。这些预防计划将被证明在减少饮食失调的发生率方面是有用的，并对其他治疗和预防战略具有影响，因为它们提供了更广泛的治疗扩展和实施的信息。

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.
