目的：关于症状变化的预测因素或可能增加用户在旨在改善心理健康结果的网站上的“依从性”的方法知之甚少。本文件：（i）研究预测的预期最终抑郁和焦虑分数的MoodGYM网站作为用户特征的函数;（ii）比较遵守率的原始网站与新的公共版本的网站（MoodGYM马克二）。后者的网站需要强制完成的“核心”在线评估，并可能会增加完成现场questionnaire.Method：MoodGYM马克我参加了19607访问者（公众注册）2001年4月至2003年9月，加上182名参与者被随机分配到MoodGYM在早期的试验（BlueMood审判）。MoodGYM Mark II参与者是2003年9月至2004年10月期间收集的MoodGYM Mark II网站的38791名公共注册者。在网站干预期间重复进行症状评估，以检查症状的变化。结果变量是性别，初始抑郁症的严重程度评分，完成的评估和最终的焦虑和抑郁scores.Results：男性预测为0.19个单位（SE = 0.095）高于女性抑郁症，控制初始抑郁水平和完成的模块数。对于高于2的初始抑郁评分，预测最终评分将指示相对于初始评分的改善，改善的幅度作为尝试的模块的数量的函数而增加。对于高于2的初始焦虑分数，预测最终分数将指示相对于初始分数的改善，改善的幅度作为尝试的模块的数量的函数而增加。Mark II注册者比Mark I注册者更有可能完成现场评估。结论：MoodGYM网站的访问者如果完成更多的网站材料，可能会有更好的心理结果。强制完成核心部分会提高评估完成率。有必要进一步审查在线干预造成的流失的重要性，制定处理缺失数据的方法，并调查改善访问者流失的战略。
Objective: Little is known about the predictors of symptom change or the methods that might increase user 'compliance' on websites designed to improve mental health outcomes. The present paper: (i) examines predictors of expected final depression and anxiety scores on the MoodGYM website as a function of user characteristics; and (ii) compares the compliance rates of the original site with the new public version of the site (MoodGYM Mark II). The latter site requires compulsory completion of 'core' online assessments and may increase completion of site questionnaires.Method: MoodGYM Mark I participants were 19 607 visitors (public registrants) between April 2001 and September 2003 plus 182 participants who had been randomly assigned to MoodGYM in an earlier trial (The BlueMood Trial). MoodGYM Mark II participants were 38 791 public registrants of the MoodGYM Mark II site collected between September 2003 and October 2004. Symptom assessments are repeated within the website intervention to allow the examination of change in symptoms. Outcome variables were gender, initial depression severity scores, number of assessments completed and final anxiety and depression scores.Results: Men are predicted to be 0.19 units (SE = 0.095) higher than women on depression, controlling for the initial depression level and number of modules completed. For initial depression scores above 2, it is predicted that the final score will indicate improvement relative to the initial score, the magnitude of the improvement increasing as a function of the number of modules attempted. For initial anxiety scores above 2, it is predicted that the final score will indicate improvement relative to the initial score, the magnitude of the improvement increasing as a function of the number of modules attempted. Mark II registrants were more likely than to Mark I registrants to complete onsite assessments.Conclusions: Visitors to the MoodGYM site are likely to have better psychological outcomes if they complete more of the site material. Compulsory completion of core sections increases assessment completion. There is a need to examine further the significance of attrition from online interventions, to develop methods of handling missing data, and to investigate strategies to improve visitor dropout.
