Trial summary

This study is investigating whether combining noninvasive brain stimulation with behavior therapy can help to improve outcomes for obsessive-compulsive disorder (OCD). Exposure and response prevention (ERP) -- a specific type of behavior therapy -- is a first line treatment for OCD. Read more about this study

  • Ages 18 to 65 years
  • All sexes
  • No healthy volunteers

About this study

Official title: tDCS for Inhibitory Control Deficits: A Test in OCD

This study is investigating whether combining noninvasive brain stimulation with behavior therapy can help to improve outcomes for obsessive-compulsive disorder (OCD). Exposure and response prevention (ERP) -- a specific type of behavior therapy -- is a first line treatment for OCD. This study will test whether a form of noninvasive brain stimulation called transcranial direct current stimulation (tDCS), can help ERP work better.

What participants receive

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

  • ERP plus tDCSOther

    Participants in the ERP plus tDCS arm will receive an 11-session program, including 10 sessions which include both tDCS and ERP. During these sessions, 20 minutes of anodal tDCS will be delivered over right inferior frontal gyrus prior to the ERP exercise.

  • ERP plus sham tDCSOther

    Participants in the ERP plus sham tDCS arm will receive an 11-session program, including 10 sessions which include both sham tDCS and ERP. During these sessions, 20 minutes of sham tDCS will be delivered over right inferior frontal gyrus prior to the ERP exercise.

What is being measured

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

  1. Yale-Brown Obsessive Compulsive Scale (Y-BOCS): Total Score

    The Y-BOCS is a well-known measure for assessing OCD symptom severity. Total scores can range from 0-40, with higher scores corresponding to greater severity of symptoms.

    Measured: Post-treatment (approximately 6.5 weeks post-baseline)

  2. Client Satisfaction Questionnaire-8: Total Score

    The Client Satisfaction Questionnaire-8 is measure of client satisfaction. Scores can range from 8-32, with higher scores corresponding to greater satisfaction.

    Measured: Post-treatment (approximately 6.5 weeks post-baseline)

  3. Rates of Session Completion

    Average number of intervention sessions completed

    Measured: Approximately 6.5 weeks post-baseline

Secondary outcomes (3)
  1. Yale-Brown Obsessive-Compulsive Scale: Total Score

    The Y-BOCS is a well-known measure for assessing OCD symptom severity. Total scores can range from 0-40, with higher scores corresponding to greater severity of symptoms.

    Measured: 1-month follow up (Approximately 11 weeks after baseline assessment)

  2. Client Satisfaction Questionnaire-8: Total Score

    The Client Satisfaction Questionnaire-8 is measure of client satisfaction. Scores can range from 8-32, with higher scores corresponding to greater satisfaction.

    Measured: 1-month follow up (Approximately 11 weeks after baseline assessment)

  3. Rates of Retention in Intervention

    Number of randomized participants who remained in the intervention phase of the study and completed all intervention sessions.

    Measured: Approximately 6.5 weeks post-baseline

Questions about this trial

What is this clinical trial studying?

A study testing ERP plus tDCS in people with Obsessive-Compulsive Disorder, run by Butler Hospital at 1 site in United States.

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 6 inclusion and 9 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 15 May 2018. 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. 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?

Yes. Results are posted in the registry (first posted 15 May 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Yale-Brown Obsessive Compulsive Scale (Y-BOCS): Total Score (time frame: Post-treatment (approximately 6.5 weeks post-baseline)). The study lists 3 primary outcomes in all. 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 15 May 2018.
