Response Inhibition Training for Individuals With Trichotillomania
Official Title
Testing the Feasibility of Response Inhibition Enhancement Training for Individuals With Trichotillomania
Brief 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. 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.
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.
