Technology Assisted Treatment for Trichotillomania

May 29, 2026 updated by: HabitAware Inc.
The investigators are testing two digital health interventions for trichotillomania (TTM), via a randomized trial design.

Study Overview

Detailed Description

Trichotillomania is characterized by recurrent hair pulling despite repeated attempts to stop, resulting in hair loss as well as significant distress and impairment. Behavior therapies focused on increasing awareness of hair pulling followed by the use of an incompatible behavior (i.e., competing response) and other behavioral strategies (e.g., stimulus control) are efficacious. In this randomized control trial, we are testing the preliminary efficacy of two digital health interventions for adults with TTM (N=90). Participants will be randomly assigned (50/50 chance) to receive 8 weeks of (a) a digital behavior therapy that includes a wrist worn motion detection device to enhance awareness and a companion mobile application that provides psychoeducation, awareness training (e.g., self-monitoring), and behavioral strategy suggestions or (b) a digital general wellness intervention that includes a reminder bracelet (i.e., a wrist-worn visual reminder not to pull) accompanied by a smartphone app that includes general context logging and delivery of general health tips.

Description

Inclusion Criteria:

  1. 18 years of age or older (criterion 1a) with a diagnosis of TTM focused on primary hair pulling location(s) above the neck (e.g., scalp, eyebrows, eye lashes, beard) (criterion 1b).
  2. English language fluency (criterion 2).
  3. Report no current pharmacological intervention targeting TTM symptoms OR a 6-week course of the intervention without change in dosage and intent for that dosage to remain stable for the 12 weeks of this trial (criterion 3a).
  4. Report no current psychosocial intervention targeting TTM (criterion 3b)

4. Reliable and consistent access to the internet and/or mobile device permitting the participant to meet with someone virtually for 90 min.

5. Owns a mobile phone running on Apple's operating system (iOS 6+) 6. Identifies a support person that is able to be contacted if an emergency arises.

Exclusion Criteria:

  1. Current suicidal/homicidal ideation, intent, or plan (criterion 1a) or a diagnosis of another psychiatric condition that may impede a participant's ability to fully utilize the app (e.g., psychotic disorder, eating disorder, moderate to severe major depressive disorder [defined by meeting diagnostic criteria on the MINI and a score >13 on DASS-21]) (criterion 1b)
  2. Has not used HabitAware's Keen or Keen2 bracelet in the past 24 months.
  3. Residing outside the United States

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Keen2 bracelet and app
8-week intervention involving a wrist-worn motion detection device (Keen2 bracelet) and accompanying smartphone app that delivers components of behavior therapy for TTM.
Participants will receive an awareness bracelet (Keen2) which vibrates upon detection of hair pulling motion, supporting behavior therapy for hair pulling delivered by the Keen2 app.
Participants will be given access to a smartphone app. The bracelet and app work together to implement key features of habit reversal training for TTM, including psychoeducation, awareness training, competing response training, and personalized just-in-time stimulus control and other behavioral strategy reminders.
Placebo Comparator: Reminder bracelet and health tips app
8-week intervention involving a wrist-worn reminder device (non-vibrating bracelet) and accompanying smartphone app that prompts for general context logging and delivers general health tips.
Participants will receive a non-vibrating bracelet to wear as a visual reminder not to pull.
Participants will be given access to a smartphone app that will prompt them to log their context (e.g., location and activity) throughout the day and provide general health tips.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinician-rated trichotillomania (TTM) symptom severity at endpoint (week 8)
Time Frame: Eight weeks
Scores on the NIMH Trichotilomania Severity Scale (NIMH-TSS), a clinician-administered assessment of TTM symptom severity, will be compared across conditions at endpoint (week 8), controlling for baseline severity. The NIMH-TSS is a 5-item clinician rated measure of TTM severity ranging from 0-25, with higher scores indicating more severe symptoms.
Eight weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Self-reported trichotillomania (TTM) severity at endpoint (week 8)
Time Frame: 8 weeks
Scores on the Massachusetts General Hospital Hair Pulling Scale (MGH-HS), a validated and widely used 7-item Likert self-report measure of TTM symptom severity, will be compared across conditions at endpoint (week 8), controlling for baseline severity. MGH-HS scores range from 0 to 28, with higher scores corresponding with more severe TTM symptoms.
8 weeks
