Comprehensive Behavioral (ComB) Treatment of Trichotillomania: A Randomized Clinical Trial.

OBJECTIVE: This study is the first controlled trial of comprehensive behavioral (ComB) treatment of trichotillomania (TTM). ComB provides individualized treatment based on factors triggering and maintaining hair pulling. METHOD: Participants (N = 36) were adults (M = 34.08 years old, SD = 12.26) meeting DSM5 criteria for TTM. A majority were female (80%) and Caucasian (75%), whereas 17% were African American and 19% Hispanic/Latinx. In a parallel-group design, participants were randomly assigned to (a) Immediate ComB (12 sessions) or (b) Minimal Attention Control (MAC), followed by delayed ComB after week 12. Follow-up continued through week 38. Primary outcomes were self-report (Massachusetts General Hospital Hair pulling Scale; MGH-HPS) and interviewer-rated (NIMH-Trichotillomania Impact Scale and Trichotillomania Severity Scale; TIS/TSS) TTM symptom severity, as well as diagnosis (Trichotillomania Diagnostic Interview). RESULTS: Immediate efficacy of ComB (vs. MAC) was statistically significant (p = .03) for self-reported symptoms, with an effect size d = -.78, but not significant for interviewer-rated symptoms or diagnostic status. Immediate ComB was significantly more likely than MAC (27% vs. 0%) to lead to complete abstinence from hair pulling at week 12. Follow-ups showed good maintenance of effects. CONCLUSIONS: Efficacy of ComB was established for self-reported symptoms. Future research is needed to establish whether the lack of more widespread effects stems from limitations of the model or to a need for more extensive therapist training, as secondary analyses suggested stronger results among therapists with more TTM experience.

Behavioral activation and inhibition in compulsive buying and obsessive-compulsive disorder.

BACKGROUND: Compulsive buying (CB) is characterized by intrusive thoughts and behaviors related to the purchase of items, whereas obsessive-compulsive disorder (OCD) seems to arise from misattributed anxiety to a neutral stimulus resulting in the avoidance of the feared stimuli. Examining the triggers for the behaviors may provide useful information to possible shared etiology. METHODS: A total of 528 participants (age: mean = 20.97, SD = 5.15 years) were recruited through an online volunteer pool at a large university. Each participant completed demographic and clinical measures as well as the Behavioral Inhibition and Activation Sensitivities (BIS/BAS) self-report questionnaire. RESULTS: The OCD group (n = 101) endorsed the highest scores on BAS Reward Responsivity, which were statistically comparable to the control (n = 365) and CB groups (n = 27), yet significantly higher than the CB/OCD group (n = 35) (P < .007). The CB group did not differ from any group with regard to the BAS. The OCD group scored significantly higher than controls (P < .001), but did not differ significantly from the CB group (P = .05) on the BIS. CONCLUSIONS: OCD and CB/OCD endorsed the highest sensitivity to threat and motivation to reduce distress. Together, these results convey anxiety and motivation to reduce distress as factors that differentiate groups and likely motivation to engage in compulsive behaviors.

Preliminary investigation of web-camera delivered cognitive-behavioral therapy for youth with obsessive-compulsive disorder.

This study reports a waitlist controlled randomized trial of family-based cognitive-behavioral therapy delivered via web-camera (W-CBT) in children and adolescents with obsessive-compulsive disorder (OCD). Thirty-one primarily Caucasian youth with OCD (range=7-16years; 19 male) were randomly assigned to W-CBT or a Waitlist control. Assessments were conducted immediately before and after treatment, and at 3-month follow-up (for W-CBT arm only). Primary outcomes included the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS), clinical global improvement rates, and remission status. When controlling for baseline group differences, W-CBT was superior to the Waitlist control on all primary outcome measures with large effect sizes (Cohen's d≥1.36). Thirteen of 16 youth (81%) in the W-CBT arm were treatment responders, versus only 2/15 (13%) youth in the Waitlist arm. Similarly, 9/16 (56%) individuals in the W-CBT group met remission criteria, versus 2/15 (13%) individuals in the Waitlist control. Gains were generally maintained in a naturalistic 3-month follow-up for those randomized to W-CBT. This preliminary study suggests that W-CBT may be helpful in reducing obsessive-compulsive symptoms in youth with OCD. Given considerable access issues, such findings hold considerable promise for treatment dissemination.

Evidence-based treatment for pediatric obsessive-compulsive disorder.

Obsessive-compulsive disorder (OCD) is marked by incessant distressing thoughts or images (obsessions) and/or overt or covert behaviors (or mental rituals) aimed to reduce anxiety (compulsions). The disorder affects 1-2% of children and adults, with up to 80% of adults reporting symptom onset prior to the age of 18 years. Without appropriate intervention, symptoms tend to run a chronic course from childhood into adulthood. Obsessive-compulsive disorder contributes to considerable impairment across multiple domains of functioning, and as a result calls for effective and efficient treatment. To date, both psychological and pharmacological interventions have shown efficacy for pediatric OCD although there are associated advantages and disadvantages that must be considered in treatment planning. The intent of this review is to discuss the current state of literature regarding treatment for pediatric OCD, highlight efficient and cost-effective means of reducing impairment, and conclude with directions for future study.

Antecedents to panic disorder in nonreferred adults.

OBJECTIVE: Previous work has shown that childhood anxiety disorders are unique antecedents for panic disorder. The current study examined both childhood and adult comorbid disorders as potential antecedent disorders to panic disorder in a large sample of nonreferred adults. METHODS: Subjects were 1018 adults with (N = 58) and without (N = 960) panic disorder who were derived from a sample originally ascertained through family studies of probands with and without attention-deficit/hyperactivity disorder (ADHD); data were obtained from 1988 to 1996. Classification and regression trees (CART) analysis was used to examine anxiety and nonanxiety disorders antecedent to panic disorder. RESULTS: CART analysis showed that separation anxiety disorder, social phobia, and simple phobia were unique predictors of subsequent panic disorder. CONCLUSION: These results support and expand previously reported findings in referred samples documenting that comorbid anxiety disorders are unique antecedent risk factors for panic disorder.
