Translated article: Change Factors in the Cognitive-Behavioral Treatment of Obsessive-Compulsive Disorders: A Critical Overview of the Current State of Research

<div>The aim of this review is to summarize the current state of</div><div>knowledge on process research regarding common factors</div><div>in psychotherapy of obsessive-compulsive disorders (OCD).</div><div>A systematic literature search of medical and psychological</div><div>publications since 2000 was conducted. Only 8 publications</div><div>fulfilled our inclusion criteria: being a psychotherapy study,</div><div>investigating potential mediators of change, and respecting</div><div>the time line issue. Most of them focused on potential cognitive factors. The change of dysfunctional obsessive beliefs, particularly perfectionism and certainty beliefs, seems</div><div>to be important for a successful reduction of OCD symptoms.</div><div>Patient adherence also seems to play a certain role as</div><div>a mediator. Concerning the effect of depression, the analysis</div><div>leaves us with inconsistent results regarding the direction</div><div>and extent of the found effect. Exploring ‘complexity’</div><div>as a potential change factor of the therapy process, 1 study</div><div>found the steepest change gradient before an intervention</div><div>with exposure-reaction management took place. Case formulation and avoidance did not turn out to be mediators of change. Overall, the limited number of available studies,</div><div>their focus on different constructs, and their often contradictory results show the need for meaningful, longitudinal research in the field of OCD.</div>
