Cognitive Behavioral Therapy for Trichotillomania (CBT for TTM)

June 19, 2012 updated by: Nancy J. Keuthen, Massachusetts General Hospital
This study aims to develop a comprehensive Cognitive Behavioral Therapy protocol for adult patients with Trichotillomania that emphasizes relapse prevention and that addresses comorbid affective symptoms, as well. The study will compare the efficacy of CBT with a minimal attention control (MAC)condition. We hypothesize that outcome at post-treatment, 3-month, and 6-month follow-up will be better for the CBT vs. MAC condition including higher responder rates and greater reduction in hair pulling severity.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to assess the efficacy of cognitive behavioral therapy for patients with trichotillomania.

Following entry into the study, subjects will be randomized into a cognitive behavioral therapy (CBT) or a minimized attention control (MAC) condition. Subjects will be assessed with the Acceptance and Action Questionnaire (AAQ), the Affective Regulation Rating (ARR), the Barratt Impulsivity Scale (BIS-11), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Clinical Global Impressions Scale (CGI), the Difficulties in Emotion Regulation Scale (DERS), Hair Pulling Scale (HPS), Trichotillomania (TTM) Impact Scale, Psychiatric Institute Trichotillomania Scale (PITS), National Institute of Mental Health Trichotillomania Severity Scale(NIMH-TSS), the Generalized Expectancy for Negative Mood Regulation Scale (NMR), The Milwaukee Inventory for Subtypes of Trichotillomania- Adult Version (MIST-A), the Positive and Negative Affect Scale (PANAS), the Quality of Life Inventory (QOLI), the Readiness to Change Hairpulling Behavior (RCHPB), the Self-Esteem Scale (SES), the Skin Picking Scale (SPS) and the Scales of Psychological Well-Being (SPWB). Subject randomization to a treatment arm will be determined by a random number generator.

Subject change scores will be assessed for the above scales.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
