Eric Lee is a 5th year student at Utah State University working with Mike Twohig. This study is a randomized controlled trial utilizing a 10-session standalone ACT protocol for trichotillomania. This study provides evidence that ACT alone is an effective treatment for people with trichotillomania.

Abstract
The purpose of this study was to examine acceptance and commitment therapy (ACT) as a standalone treatment for trichotillomania in a randomized controlled trial of adults and adolescents. Participants consisted of a community sample of treatment seeking adults and adolescents with trichotillomania. Of the eligible 39 participants randomized into treatment and waitlist groups, 25 completed treatment and were included in the final analysis. Treatment consisted of a 10-session ACT protocol. Multiple mixed models repeated measures analyses were utilized to evaluate changes in trichotillomania symptom severity, daily number of hairs pulled and urges experienced, and experiential avoidance from pretreatment to posttreatment. Findings indicated significant changes in symptom severity and daily hairs pulled, but not daily urges experienced or psychological flexibility. However, psychological flexibility saw a 24.5% decrease in the treatment group and reduced from clinical to subclinical levels on average. This study suggests that ACT alone is an effective treatment for adults and adolescents with trichotillomania. Outcomes appear to be similar to trials that combined ACT and habit reversal training (HRT).

 

Leah Bogusch is a 4th year student at Bowling Green State University. This study is a case study in which the authors utilize ACT as a treatment for a client with emetophobia (phobia of vomiting). The results indicate symptom improvement from pre-treatment, post-treatment, 6-month follow up, and 12-month follow up.

Abstract
Acceptance and Commitment Therapy (ACT) is a third-wave behavioral therapy that is an empirically supported treatment for various mental health concerns. ACT has been found to be efficacious for treating different types of anxiety disorders. This case study presents the conceptualization (functional analysis), treatment (ACT), and treatment outcomes of a client who presented with emetophobia, a phobia of vomiting, complicated by a metabolic disorder. Measures of emetophobia symptoms, mindfulness, cognitive fusion, thought control strategies, and believability of anxious thoughts and feelings, were collected at pretreatment, posttreatment, 6-month follow-up, and 12-month follow-up. The Reliable Change Index was used to evaluate changes across time. Large and clinically significant decreases on all measures were observed at posttreatment. At 12-month follow-up, improvements were maintained on all measures except the Reappraisal subscale of the Thought Control scale. The implications of this study are discussed, and recommendations are made for clinicians using ACT for the treatment of emetophobia.
