Trial summary

This study tests a computerized cognitive training program designed for young individuals with compulsive hair pulling (also known as trichotillomania;TTM). Research suggests that individuals with TTM are characterized by poor cognitive abilities to suppress irrelevant response. Read more about this study

About this study

Official title: Testing the Feasibility of Response Inhibition Enhancement Training for Individuals With Trichotillomania

This study tests a computerized cognitive training program designed for young individuals with compulsive hair pulling (also known as trichotillomania;TTM). Research suggests that individuals with TTM are characterized by poor cognitive abilities to suppress irrelevant response. This ability is called response inhibition. The current study tests a cognitive training program designed to improve individuals' cognitive abilities of response inhibition through a 8-session computerized training program. The investigators hypothesize that those who complete the response inhibition training program will show a greater reduction in hair pulling symptoms, compared to those assigned to a waitlist group.

Read the detailed description

Despite ongoing research into causes and treatments for trichotillomania, it remains poorly understood, underdiagnosed and inadequately treated. Further, treatment of TTM in children has received little attention, and only recently have the investigators begun to see research in pediatric trich. One possible way of progressing treatment development for pediatric trich is to clarify the nature of inhibitory control processes implicated in TTM and to develop a treatment that specifically targets these implicated cognitive processes. Examples of this strategy are found in the increasing availability of translational research that has demonstrated the therapeutic benefits of computerized cognitive training programs (CTPs) in modifying problematic cognitive processes in numerous psychiatric conditions. The objective of this study is to examine the feasibility of CTP for enhancing response inhibition capabilities among individuals with trich, thereby reducing TTM symptoms.

To this end, young individuals aged between 12 and 18 with TTM will be randomly assigned to the CTP condition vs. a wait-list condition. Participants in the CTP condition will receive eight 30-min training sessions over a 4-week period and will be assessed at three time points. Participants in the wait-list will be evaluated at baseline and post-training assessments, and will be allowed to receive the CTP after completing the post-training assessment. Wait-list controls who choose to cross over to the CTP condition will also provide a small replication sample to test the effect of our response inhibition training.

There are three primary implications from this work. First, demonstrating successful enhancement in response inhibition by our proposed CTP is expected to create ample opportunities for clinical research not only on TTM, but also for numerous other psychiatric problems in which poor response inhibition is implicated (e.g., Chronic Skin Picking, Tourette Syndrome, OCD, and ADHD).

This research has the potential to produce a highly cost-efficient self-administered intervention for TTM. Upon establishing efficacy, CTPs may be easily integrated into various contexts, examples include CTPs as an adjunctive intervention to existing behavioral and/or pharmacological treatments, an instrument to identify and help at-risk individuals for preventative training, a stand-alone short-term intervention, and a remote web-based self-help intervention for individuals who have no easy access to treatment resources or are reluctant to seek treatment.

    This is a computerized cognitive retraining program consisting of 8 sessions delivered over a 4-week period.

What is being measured

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

  1. NIMH Trichotillomania Severity and Impairment Rating Scale

    This is one of the most widely clinician-interview based measure designed to assess the severity of hair pulling symptoms during the previous week. We administer this outcome measure at the baseline prior to the intervention.

    Measured: Baseline

  2. NIMH Trichotillomania Severity and Impairment Rating Scale

    This primary outcome measure will be administered again at 4 week after completing the intervention or after completing the 1-month waiting period.

    Measured: 4 week

  3. NIMH Trichotillomania Severity and Impairment Rating Scale

    This primary outcome measure will be administered again at 8 week, which is designed for a 1-month follow-up assessment after completing the intervention.

    Measured: 8 week

Secondary outcomes (3)
  1. Clinical Global Impression (CGI)

    This is a clinician-administered rating scale that is widely used in clinical outcome research to evaluate treatment outcomes with respect to overall levels of severity and improvement.

    Measured: Baseline

  2. Clinical Global Impression (CGI)

    This measure will be administered at 4 week (after completing the training or 1-month waiting period).

    Measured: 4 week

  3. Clinical Global Impression (CGI)

    This measure will be administered at 8 week for a 1-month follow-up assessment to examine the longterm effect of the intervention.

    Measured: 8 week

Questions about this trial

What is this clinical trial studying?

A study testing Response Inhibition Training Program in people with Trichotillomania, run by University of Wisconsin, Milwaukee 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 2 inclusion and 5 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 20 Jan 2014. 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?

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?

NIMH Trichotillomania Severity and Impairment Rating Scale (time frame: 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?

On the ClinicalTrials.gov record for NCT01638975, which also lists 1 linked publication.

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 20 Jan 2014.
