NCT03799419

Brief Summary

This study will conduct the development and preliminary evaluation of Cognitive Bias Modification for Interpretation (CBM-I) and Approach Avoidance Training (AAT) as augmentations to treatment as usual for OCD and related disorders. CBM-I refers to computerized interventions designed to directly manipulate interpretation bias through repeated practice on a training task, thereby inducing cognitive changes in a relatively automatic or implicit manner. In AAT, automatic approach tendencies toward feared stimuli are re-trained. Specifically, this study will examine the feasibility, acceptability, and clinical outcomes associated with CBM-I and AAT. Adults with obsessive compulsive disorder (OCD) and related disorders will be recruited from a treatment program for these disorders and participants will be randomly assigned to either receive: 1) eight sessions of CBM-I or eight sessions of psychoeducation as a control condition, or 2) AAT or eight sessions of an inactive (sham) version of the AAT training.

Outcome Measures

Primary Outcomes (1)

  • Change in Average Score on Obsessive Beliefs Questionnaire

    Measure of interpretation biases, specifically: Inflated Responsibility/Overestimation of Threat, Perfectionism/Intolerance of Uncertainty, and Importance/Control of Thoughts. 44-item self-report measure, items scored 1-7 and summed; greater scores indicate greater severity.

    Weeks 0, 2, 4, and 8

Secondary Outcomes (9)

  • Change in Average Score on Yale-Brown Obsessive Compulsive Scale

    Weeks 0, 4, and 8

  • Change in Columbia-Suicide Severity Rating Scale

    Weeks 0, 4, and 8

  • Change in Suicide Implicit Association Test

    Weeks 0, 2, and 4

  • Change in Average Score on Depressive Symptom Index Suicidality Subscale. There are 4 items scored from 0-3 with greater numbers indicating greater severity.

    Weeks 0, 1, 2, 3, and 4

  • Credibility/Expectancy Questionnaire

    Week 0

  • +4 more secondary outcomes

Interventions

Eight sessions of scenario-based CBM-I training for OCD will be administered, based on the widely-used paradigm of ambiguous scenario training developed by Mathews and Mackintosh (2000), in which participants are presented with scenarios that are ambiguous in whether or not they are threatening. Participants will complete a computer task consisting of a series of written scenarios designed to improve interpretation and attributional biases; these scenarios conclude with word fragments, which participants must fill in to resolve the ambiguity.

Cognitive bias modification with treatment as usual
PsychoeducationBEHAVIORAL

Eight sessions of psychoeducation will be administered, which will describe symptoms of anxiety, the nature of biased thinking in anxiety, and summarize common psychosocial as well as pharmacological treatments for anxiety. The sessions will provide relevant information but will not provide training in changing thinking styles.

Psychoeducation with treatment as usual

Eight sessions of this computerized training program will be used to train approach tendencies, following previously validated procedures (Najmi, Kuckertz, \& Amir, 2010). During the training program, participants will view a series of these images and be prompted to push or pull a joystick according to prompts on the screen, instead of the content of the picture. Avoidance will be stimulated through both pushing away (images on the screen will decrease in size upon the joystick being pushed), and approach will be stimulated through pulling towards pictures (images will increase in size to simulate approach).

Approach avoidance training with treatment as usual

Eight sessions of the approach avoidance training will be administered, however the percentage of push vs pull trials will be altered in this sham version of the training.

Inactive sham approach avoidance training
