背景：计算机自助具有交互式、会话式的形式，具有几个优点，例如在提出问题时的灵活性和易用性。我们设计了一个名为MYLO的新程序，该程序利用基于感知控制理论（PCT）的水平方法（MOL）治疗原理。目的：我们检验MYLO的疗效，检验PCT描述的心理变化机制是否介导了其疗效，并评估来访者期望的效果。方法：48名学生被随机分配到MYLO或比较计划ELIZA。参与者讨论了他们目前在指定项目中遇到的问题，并完成了干预前、干预后和两周随访期间的痛苦、解决和期望测量。结果：MYLO和ELIZA与痛苦、抑郁、焦虑和压力的减少有关。MYLO被认为更有帮助，能够更好地解决问题。心理变化过程预示着MYLO的乐于助人和减少痛苦的评分更高。对基于计算机的问题解决的积极期望与MYLO的感知帮助和更大的问题解决相关，这部分是由所确定的心理变化过程介导的。结论：研究结果为MYLO项目在非临床样本中的可接受性提供了暂时的支持，尽管它作为一种创新的基于计算机的解决问题的辅助手段的有效性尚不清楚。尽管如此，研究结果为PCT中确定的心理变化机制提供了初步的支持，并强调了客户期望对预测计算机自助参与的重要性。
Background: Computerized self-help that has an interactive, conversational format holds several advantages, such as flexibility across presenting problems and ease of use. We designed a new program called MYLO that utilizes the principles of Method of Levels (MOL) therapy - based upon Perceptual Control Theory (PCT). Aims: We tested the efficacy of MYLO, tested whether the psychological change mechanisms described by PCT mediated its efficacy, and evaluated effects of client expectancy. Method: Forty-eight student participants were randomly assigned to MYLO or a comparison program ELIZA. Participants discussed a problem they were currently experiencing with their assigned program and completed measures of distress, resolution and expectancy preintervention, postintervention and at 2-week follow-up. Results: MYLO and ELIZA were associated with reductions in distress, depression, anxiety and stress. MYLO was considered more helpful and led to greater problem resolution. The psychological change processes predicted higher ratings of MYLO's helpfulness and reductions in distress. Positive expectancies towards computer-based problem solving correlated with MYLO's perceived helpfulness and greater problem resolution, and this was partly mediated by the psychological change processes identified. Conclusions: The findings provide provisional support for the acceptability of the MYLO program in a non-clinical sample although its efficacy as an innovative computer-based aid to problem solving remains unclear. Nevertheless, the findings provide tentative early support for the mechanisms of psychological change identified within PCT and highlight the importance of client expectations on predicting engagement in computer-based self-help.
