Telepsychotherapy for the Treatment of Trichotillomania: A Randomized Controlled TrialLee, Eric B. 01 May 2018 (has links)
Trichotillomania is defined as recurrent pulling of one’s hair that results in distress and negative effects on general functioning and quality of life. Estimates of trichotillomania lifetime prevalence generally range from approximately 1% to 3% and it is likely as common as disorders such as obsessive-compulsive disorder and agoraphobia. Yet, quality treatment for trichotillomania is often difficult to find as many mental health professionals are uninformed about the disorder and its treatment. Moreover, mental health services in general are inaccessible to many with estimates suggesting that 96.5 million people do not have access to adequate services. The use of telepsychology has been an effective method for disseminating treatment services for a variety of mental health conditions. However, no research has examined the effectiveness of telepsychology to treat trichotillomania.
The current study reports the results of a randomized clinical trial of Acceptance and Commitment Therapy Enhanced Behavior Therapy for the treatment of trichotillomania delivered by way of telepsychology. The study compared an active treatment condition (n = 12) to a waitlist control condition (n = 10). Results showed significant reductions in hair pulling severity from pre- to post-treatment compared to the waitlist condition.
Participants in the waitlist condition received the same treatment as participants in the treatment condition following the waitlist period. All participants were then combined to examine overall treatment effects from pre-treatment to a 12-week follow-up. The effect of treatment on hair pulling severity was still significant at follow-up, however the effect was not as strong as at post-treatment. Conversely, the effect on quality of life was maintained and even increased following post-treatment. Additional measures of psychological flexibility, perceived shame, and valued action also saw significant changes from pre-treatment to follow-up. The findings demonstrate that telepsychology is a viable option to disseminate treatment for trichotillomania. Implications, limitations, and future research directions are discussed.

Experiential Avoidance in Chronic Tic Disorders: an Online Survey and Pilot Treatment Study Using Habit Reversal and Acceptance and Commitment TherapyBest, Stephanie Helena January 2009 (has links)
<p>Among some researchers, there is an emerging conceptualization of chronic tic disorders (CTDs) as conditions that are partially rooted in avoidance of tic-related private experiences (i.e., painful or difficult thoughts and feelings) and internal sensations (i.e., premonitory urges to tic). The first specific aim of the present research was to investigate the possibility that experiential avoidance is related to tic severity and perceived quality of life in individuals with CTDs. The second aim was to determine whether the efficacy of Habit Reversal Training (HRT), the most prevalent and effective behavioral intervention for CTDs to date, might be enhanced by combining it with Acceptance and Commitment Therapy (ACT), an intervention that directly targets experiential avoidance. These aims were addressed by conducting two related studies. Study I, an online survey, included 239 adults (<italic>M</italic> = 37.6 years; <italic>SD</italic> = 13.8 years) who reported having been previously diagnosed with a CTD. Results showed that levels of premonitory urges, as well as both general and tic-specific experiential avoidance, were significantly positively related to tic severity. General and tic-specific experiential avoidance were also significantly negatively related to perceived quality of life. Psychometric analyses of two novel measures developed for Study I (i.e., the Yale Global Tic Severity Scale-Self-Report Version and the Acceptance and Action Questionnaire-Tic-Specific Version) demonstrated excellent internal consistency and convergent validity. Study II, a multi-site pilot investigation, involved 13 adolescents (<italic>M</italic> = 15.4 years; <italic>SD</italic> = 1.3 years) who were treated with either HRT alone or a novel HRT+ACT intervention. Results suggest that the HRT+ACT treatment is feasible, highly acceptable to both patients and parents, and as effective as HRT alone at reducing tic severity from pre-treatment through week 22 follow-up. Participants in both groups reported clinically significant post-treatment decreases in general and tic-specific experiential avoidance and improvements in overall functioning. Researchers concluded that experiential avoidance plays an important role in tic expression and overall functioning for individuals with CTDs. Results support additional development and testing of the promising HRT+ACT intervention, to evaluate its efficacy alone and in comparison to other relevant psychosocial and pharmacological interventions.</p> / Dissertation
