About this study

Official title: Cognitive Bias Modification as an Adjunctive Treatment for Treatment-Refractory OCD

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cognitive bias modification for interpretation biasBehavioural

    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.

  • PsychoeducationBehavioural

    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.

  • Approach avoidance trainingBehavioural

    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).

  • Inactive sham approach avoidance trainingBehavioural

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: Weeks 0, 2, 4, and 8

Secondary outcomes (9)
  1. Change in Average Score on Yale-Brown Obsessive Compulsive Scale

    Interviewer-rated measure of OCD symptoms. It is 19 items, with only items 1-10 scored (from 0-4). Total scores range from 0-40, with higher scores reflecting greater severity.

    Measured: Weeks 0, 4, and 8

  2. Change in Columbia-Suicide Severity Rating Scale

    An interviewer-rated assessment of retrospective suicidality as well as recent suicidal ideation and behavior. Minimum total score 0, maximum total score 5, higher total scores indicate more suicidal ideation and/or behavior.

    Measured: Weeks 0, 4, and 8

  3. Change in Suicide Implicit Association Test

    Computerized task which assesses implicit thoughts about self-injury, death, and suicide.

    Measured: Weeks 0, 2, and 4

  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.

    Self-report measure of suicidality

    Measured: Weeks 0, 1, 2, 3, and 4

  5. Credibility/Expectancy Questionnaire

    Measure of treatment expectancy and rationale credibility in our study. The items are rated on 9-point scales, with a total score range of 3 to 27. Greater scores indicate greater expectations and perceptions of treatment credibility.

    Measured: Week 0

  6. Exit Interview

    This interview will be conducted by a member of the study staff to obtain participant feedback on satisfaction and how the intervention might be improved.

    Measured: Week 4

  7. Change in Behavioral Approach Test

    Behavioral Approach Test (BAT) will be administered as a measure of OCD-related avoidance, based on previously validated procedures (Cougle et al., 2007; Amir, Kuckertz, \& Najmi, 2013). Participants rate peak anxiety 0-100 for each step of approaching feared stimuli.

    Three different types of BAT will be implemented in order to measure avoidance with multiple types of contaminants, each with six steps on a hierarchy to be completed sequentially, providing a rating of anxiety 0-100 for each step.

    Measured: Weeks 0, 2, and 4

  8. Change in Average Score on Behavioral Inhibition/Behavioral Activation Scales

    24-item measure of behavioral approach and behavioral avoidance, rated 1-4 and summed.

    Measured: Weeks 0, 2, 4, and 8

  9. Dimensional Obsessive-Compulsive Scale

    (DOCS; Abramowitz et al., 2010) participants with contamination fears will be identified by their DOCS contamination subscale score; the DOCS is part of the admission measures in the OCD Institute's main study protocol. Additionally, we will examine these scores as an outcome measure for contamination-related obsessions and compulsions. It includes 20 items and is rated 0-4.

    Measured: Weeks 0, 2, 4, and 8

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Average Score on Obsessive Beliefs Questionnaire (time frame: Weeks 0, 2, 4, and 8). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2024.
