Personalized Inhibitory Control Training for Compulsive Behavior Change
A study testing P-CIT protocol in people with OCD, run by Hebrew University of Jerusalem at 1 site in Israel.
Trial summary
Obsessive-compulsive disorder (OCD) is a severe mental illness characterized by repetitive behaviors that a person feels compelled to perform. It has been demonstrated that stimuli in the environment can trigger the compulsive urge, perpetuating the OCD cycle. Read more about this study

About this study
Obsessive-compulsive disorder (OCD) is a severe mental illness characterized by repetitive behaviors that a person feels compelled to perform. It has been demonstrated that stimuli in the environment can trigger the compulsive urge, perpetuating the OCD cycle. The main goal of the current proposal, which is based on exciting pilot data, is to test a novel computerized training program to create an association between OCD-related stimuli, which typically trigger the compulsive urge, and the brain system responsible for stopping. The idea is that once this system is triggered, it will be easier for patients to stop the compulsive urge.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
P-CIT protocolBehavioural
Personalized inhibitory control training for one week.
PlaceboBehavioural
without personalized inhibitory control training for one week.
| Study group | Role | What they receive |
|---|---|---|
| P-CIT protocol | Experimental | OCD patients who receive the P-CIT intervention. Receives: Behavioral: P-CIT protocol |
| Placebo | Placebo comparator | OCD patients who don't receive the P-CIT intervention. Receives: Behavioral: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
fMRI- changed inhibition levels in the pre-SMA area in experimental group in comparison to control group
During tasks that require inhibition
Measured: One week after P-CIT training starts
fMRI- changed inhibition levels in the rIFG area in experimental group in comparison to control group
During tasks that require inhibition
Measured: One week after P-CIT training starts
Secondary outcomes (3)
Behavioural- Y-bocs (Yale-Brown Obsessive-Compulsive Scale) score- change in OCD symptoms in experimental group in comparison to placebo group
Clinical assessment. Semi-structured interview that assesses the presence and severity of obsessions and compulsions over the past week. The 5-item Obsession Severity and Compulsion Severity subscales are summed to produce a Total Severity score. Symptoms endorsed are rated on a scale from none (0) to extreme (5). The 5-item Obsession Severity and Compulsion Severity subscales are summed to produce a Total Severity score.
Measured: One week after P-CIT (Personalized Inhibitory Control Training for Compulsive Behavior Change) training
Behavioural- M.I.N.I (Mini-International Neuropsychiatric Interview) score- change in OCD symptoms in experimental group in comparison to placebo group
Clinical assessment. Structural interview.
Measured: One week after P-CIT (Personalized Inhibitory Control Training for Compulsive Behavior Change) training
Behavioural- OCI-R (Obsessive-Compulsive Inventory) score- change in OCD symptoms in experimental group in comparison to placebo group
Clinical assessment. Cutoff score of 21 is distinguish individuals with OCD from those without anxiety disorders.
Measured: One week after P-CIT (Personalized Inhibitory Control Training for Compulsive Behavior Change) training
