NCT07224126

Brief Summary

This open-label feasibility trial evaluates the use of the Keen2 awareness bracelet for adults with trichotillomania (hair-pulling disorder). Participants will use the bracelet for eight weeks. During the first four weeks, they will wear the device and log contextual information (such as emotions, location, and activity) after each detected hair-pulling episode. Based on these data, participants will then receive tailored predictive alerts designed to support use of stimulus control, competing responses, and coping strategies. The study will assess usability, adherence, and changes in self-reported hair-pulling severity and awareness.

Outcome Measures

Primary Outcomes (1)

  • Change in Trichotillomania Symptom Severity (NIMH-TSS)

    The primary outcome is the change in total score on the NIMH Trichotillomania Symptom Severity Scale (NIMH-TSS) from baseline to week 8. The NIMH-TSS is a clinician-rated scale assessing the frequency, intensity, and distress associated with hair-pulling behavior. Higher scores indicate greater symptom severity. A reduction in score reflects improvement.

Study Arms (1)

Single-Arm Intervention: Keen2 Predictive Awareness Bracelet

EXPERIMENTAL

Participants in this single-arm study will receive a Keen2 awareness bracelet and companion mobile app for an 8-week period. During the first 4 weeks, participants will use the device to detect hair-pulling episodes and record contextual details (such as time, emotional state, activity, and location) after each detection. In the second 4 weeks, participants will receive predictive vibration alerts generated from their prior behavioral patterns. These alerts are designed to prompt preventive actions across three domains: (1) stimulus control (reducing environmental triggers), (2) competing response training (engaging hands in alternative behaviors), and (3) coping strategies (using relaxation or cognitive techniques).

Behavioral: Keen2 Predictive Awareness Bracelet

Interventions

The Keen2 is a wrist-worn awareness bracelet paired with a mobile app that helps individuals with trichotillomania recognize and reduce hair-pulling behavior. The bracelet uses motion sensors to detect hand movements consistent with pulling and delivers gentle vibration alerts to increase awareness. During the first four weeks, participants log contextual information about each detected episode, including emotional state, location, and activity. Based on these data, the system delivers predictive vibration alerts during weeks five through eight to prompt behavior change strategies across three domains: (1) stimulus control, (2) competing response training, and (3) coping strategies.
