Unlike traditional interventions, Internet interventions allow for objective tracking and examination of the usage of program components. Student Bodies (SB), an online eating disorder (ED) prevention program, significantly reduced ED attitudes/behaviors in college-aged women with high body image concerns, and reduced the development of EDs in some higher risk subgroups. The authors investigated how adherence measures were associated with ED attitudes and behaviors after treatment. Female SB participants (n = 209) completed the Eating Disorders Examination-Questionnaire (EDE-Q; C. G. Fairburn & S. J. Beglin, 1994) at baseline, posttreatment, and 1-year follow-up. Total weeks participation and frequency of utilizing the online Web pages/journals predicted pre- to posttreatment changes in EDE-Q Restraint but not in other ED symptoms. In participants with some compensatory behaviors, discussion board and booster session use were associated with increased weight/shape concerns during follow-up. In overweight participants, higher online Web page/journal use was related to decreased EDE-Q Eating Concern scores during follow-up. This is the first study to investigate the relationship between adherence to specific program components and outcome in a successful Internet-based intervention. Results can be used to inform future development and tailoring of prevention interventions to maximize effectiveness and facilitate dissemination.
与传统干预措施不同，互联网干预措施能够对项目组件的使用情况进行客观跟踪和考察。“学生健康”（Student Bodies，简称SB）是一项在线饮食失调预防项目，该项目显著降低了对身体形象高度关注的大学适龄女性的饮食失调态度/行为，并减少了一些高风险亚组中饮食失调症的发生。作者调查了治疗后依从性指标与饮食失调态度和行为之间的关联。女性SB参与者（n = 209）在基线、治疗后及1年随访时完成了饮食失调检查问卷（EDE-Q；C.G.费尔伯恩和S.J.贝格林，1994年）。参与的总周数以及使用在线网页/日志的频率预测了治疗前到治疗后EDE-Q克制量表得分的变化，但对其他饮食失调症状没有影响。在有一些代偿行为的参与者中，讨论板和强化课程的使用与随访期间体重/体型关注度的增加有关。在超重参与者中，较高的在线网页/日志使用频率与随访期间EDE-Q饮食关注度得分的降低有关。这是第一项研究成功的基于互联网的干预措施中对特定项目组件的依从性与结果之间关系的研究。研究结果可用于为未来预防干预措施的开发和定制提供参考，以最大限度地提高有效性并促进传播。
