According to cognitive models, obsessive compulsive symptoms result from catastrophic misinterpretations of commonly occurring intrusive experiences and the use of counterproductive strategies to manage them. Obsessive Compulsive Disorder (OCD) related beliefs such as inflated responsibility, importance of thoughts and perfectionism increases the likelihood of such misinterpretations. Consistent with a growing body of literature supporting the usefulness of mobile delivered technologies in fostering cognitive behavior change, the present study assessed the effectiveness of a novel cognitive training exercise designed to challenge OCD-related beliefs. This mobile app training exercise consists of users having to pull statements challenging OCD beliefs towards themselves (downwards) and to throw away (push upwards) contra-productive self-statements.
36 third-year BA students started the trial. Twenty completed pre and post measures of OCD-beliefs, mood and OCD symptoms including relationship-obsessions. Participants were instructed to complete 3 min of daily training for a period of 15 days.
No significant differences were found between completers and non-completers on demographic and most symptom related measures at Time 1. Repeated-measures MANOVA of the 20 completers showed a significant reduction on all OCD symptoms measures and on OCD-beliefs. No significant reduction was found in depression symptoms. Regression analysis showed change in levels of OCD-beliefs was associated with reduction in OCD symptoms at Time 2 over and above OCD symptoms at Time 1.
The study is an open trial with non-clinical participants.
This mobile delivered training exercise may be useful for the reduction and relapse prevention of OCD-related beliefs and symptoms.
根据认知模型，强迫症状源于对常见侵入性体验的灾难性误解以及使用适得其反的策略来应对这些体验。诸如夸大责任感、思想的重要性和完美主义等与强迫症（OCD）相关的信念增加了此类误解的可能性。与越来越多支持移动技术在促进认知行为改变方面有用性的文献一致，本研究评估了一种旨在挑战与强迫症相关信念的新型认知训练练习的有效性。这种移动应用训练练习要求用户将挑战强迫症信念的陈述拉向自己（向下），并扔掉（向上推）适得其反的自我陈述。
36名三年级文学学士学生开始了该试验。20名学生完成了强迫症信念、情绪和强迫症症状（包括关系强迫观念）的前后测量。参与者被指示每天进行3分钟的训练，为期15天。
在第1阶段，完成者和未完成者在人口统计学和大多数症状相关测量上没有发现显著差异。对20名完成者进行的重复测量多变量方差分析显示，所有强迫症症状测量和强迫症信念都有显著降低。抑郁症状没有显著降低。回归分析表明，在第2阶段，强迫症信念水平的变化与强迫症症状的降低相关，且超过了第1阶段的强迫症症状。
该研究是一项针对非临床参与者的开放试验。
这种移动提供的训练练习可能有助于减少和预防与强迫症相关的信念和症状的复发。
