Neurocognitive functioning in adults with trichotillomania: Predictors of treatment response and symptom severity in a randomized control trial.

Trichotillomania (TTM) is associated with impairments in response inhibition and cognitive flexibility, but it is unclear how such impairments relate to treatment outcome. The present study examined pre-treatment response inhibition and cognitive flexibility as predictors of treatment outcome, change in these domains from pre-to post-treatment, and associations with TTM severity. Participants were drawn from a randomized controlled trial comparing acceptance-enhanced behavior therapy (AEBT) to psychoeducation and supportive therapy (PST) for TTM.

Intensive Cognitive-Behavioral Therapy Telehealth for Pediatric Obsessive-Compulsive Disorder During the COVID-19 Pandemic: Comparison With a Matched Sample Treated in Person.

Objective: This naturalistic, nonblinded, nonrandomized study examined the efficacy of multimodal treatment including intensive cognitive-behavioral therapy (CBT) for pediatric obsessive-compulsive disorder (OCD) delivered via telehealth (TH) compared with a matched sample of youth treated in person (IP).

Method: Patients included 1,286 youth ages 7 to 17 inclusive (643 TH, 643 IP) who received TH or IP in either partial hospitalization (n = 818) or intensive outpatient (n = 468) programs. Changes in patient-rated OCD symptoms and quality of life from pretreatment to posttreatment were examined.

The role of psychological flexibility in acceptance-enhanced behavior therapy for trichotillomania: Moderation and mediation findings.

Trichotillomania is characterized by recurrent pulling out of one's hair, leading to significant hair loss and accompanied by clinically significant distress and/or functional impairment. The current study used data from a randomized controlled trial comparing the effectiveness of acceptance-enhanced behavior therapy (AEBT) to psychoeducation plus supportive therapy (PST; active control) for trichotillomania in an adult sample. The objectives were to examine the moderating and mediating influence of trichotillomania-specific psychological flexibility in treatment for trichotillomania.

Acceptance-enhanced behavior therapy for trichotillomania in adults: A randomized clinical trial.

Given the limited treatment options for trichotillomania (TTM), or Hair Pulling Disorder, this large randomized clinical trial evaluated the efficacy of acceptance-enhanced behavior therapy for TTM (AEBT-TTM) in reducing TTM severity relative to psychoeducation and supportive therapy (PST). Eighty-five adults (78 women) with TTM received 10 sessions (over 12 weeks) of either AEBT-TTM or PST. Independent evaluators masked to treatment assignment assessed participants at baseline (week 0), midpoint (week 6), and endpoint (week 12).

Systematic Review and Meta-analysis: An Empirical Approach to Defining Treatment Response and Remission in Pediatric Obsessive-Compulsive Disorder.

Objective: A lack of universal definitions for response and remission in pediatric obsessive-compulsive disorder (OCD) has hampered the comparability of results across trials. To address this problem, we conducted an individual participant data diagnostic test accuracy meta-analysis to evaluate the discriminative ability of the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) in determining response and remission. We also aimed to generate empirically derived cutoffs on the CY-BOCS for these outcomes.

Therapist Behavior During Exposure Tasks Predicts Habituation and Clinical Outcome in Three Randomized Controlled Trials for Pediatric OCD.

This study measured therapist behaviors in relation to subsequent habituation within exposure tasks, and also tested their direct and indirect relationships (via habituation) with clinical outcomes of exposure therapy. We observed 459 videotaped exposure tasks with 111 participants in three clinical trials for pediatric obsessive-compulsive disorder (POTS trials). Within exposure tasks, therapist behaviors and patient fear were coded continuously.

The effects of depression on the treatment of OCD in a residential sample.

Studies investigating the impact of depressive symptoms on obsessive-compulsive disorder (OCD) treatment have yielded mixed findings. The purpose of the study is to extend previous research, which primarily used outpatient samples, to determine whether depression affects OCD treatment outcome among patients receiving intensive residential treatment. OCD patients receiving residential treatment based primarily on exposure and response prevention (ERP) provided data regarding symptoms of depression and OCD at admission and discharge.

Effect of D-Cycloserine on the Effect of Concentrated Exposure and Response Prevention in Difficult-to-Treat Obsessive-Compulsive Disorder: A Randomized Clinical Trial.

Importance: Evidence is lacking for viable treatment options for patients with difficult-to-treat obsessive-compulsive disorder (OCD). It has been suggested that D-cycloserine (DCS) could potentiate the effect of exposure and response prevention (ERP) treatment, but the hypothesis has not been tested among patients with difficult-to-treat OCD.

Objective: To evaluate whether DCS potentiates the effect of concentrated ERP among patients with difficult-to-treat OCD.

Measuring Treatment Response in Pediatric Trichotillomania: A Meta-Analysis of Clinical Trials.

In clinical trials of pediatric trichotillomania (TTM), three instruments are typically employed to rate TTM severity: (1) the Massachusetts General Hospital Hair Pulling Scale (MGH-HPS), (2) the National Institute of Mental Health Trichotillomania Severity Scale (NIMH-TSS), and (3) the Trichotillomania Scale for Children (TSC). These instruments lack standardized definitions of treatment response, which lead researchers to determine their own definitions of response and potentially inflate results. We performed a meta-analysis to provide empirically determined accuracy measures for percentage reduction cut points in these three instruments.

Acceptance-enhanced behavior therapy for trichotillomania: Randomized controlled trial rationale, method, and strategies for recruiting minority participants.

Trichotillomania (TTM) involves the chronic pulling out of hair to the point of hair loss or thinning, which continues despite repeated attempts to stop. Behavior therapy is a promising treatment for the condition, but studies have been limited by the lack of a credible control condition, small sample sizes, follow-up periods of short duration, and low participation by underrepresented populations. In the current article, the authors describe the theoretical rationale for an acceptance-enhanced form of behavior therapy for TTM in adults and describe the methodology used to test the efficacy of this intervention against a psychoeducation and supportive control condition.

A latent profile analysis of age of onset in trichotillomania.

Background: Trichotillomania (TTM) onset may occur across the lifespan; however, adolescent onset is most frequently reported. Several studies have explored clinical differences between TTM age-of-onset groups with mixed results. We investigated empirically defined age-of-onset groups in adults with TTM, and clinical differences between groups.

Characteristics of outpatients diagnosed with the selective/neophobic presentation of avoidant/restrictive food intake disorder.

Objective: Although Avoidant/Restrictive Food Intake Disorder (ARFID) has existed since the publication of DSM-5 in 2013, research on the descriptive psychopathology of treatment-seeking patients with formal ARFID diagnoses is sparse, and limited to tertiary eating disorder-focused treatment settings where most patients present with weight loss/malnutrition. In these settings, the selective/neophobic symptom presentation is rare compared to other primary eating restrictions. We aimed provide initial descriptive psychopathology of ARFID primary selective/neophobic symptom presentation in an outpatient setting, and to explore the prevalence of the core ARFID symptoms and clinical differences among patients meeting criteria based on weight/nutritional symptoms versus psychosocial impairment only.

A latent profile analysis of age of onset in pathological skin picking.

Background: Pathological Skin Picking (PSP) may begin at any age, but the most common age of onset is during adolescence. Age of onset is a potentially useful clinical marker to delineate subtypes of psychiatric disorders. The present study sought to examine empirically defined age of onset groups in adults with PSP and assess whether groups differed on clinical characteristics.

Negative Valence in Autism Spectrum Disorder: The Relationship Between Amygdala Activity, Selective Attention, and Co-occurring Anxiety.

Background: A critical agenda of the National Institutes of Health Research Domain Criteria (RDoC) initiative is establishing whether domains within the RDoC matrix are truly transdiagnostic. Rates of anxiety disorders are elevated in autism spectrum disorder (ASD), but it is unclear whether the same mechanisms contribute to anxiety in individuals with and without ASD. As changes in selective attention are a hallmark of anxiety disorders in non-ASD samples, the identification of these changes in ASD would support the transdiagnostic nature of anxiety.

Clarifying the Relationship between Trichotillomania and Anxiety.

Although research has consistently linked unidimensional anxiety with Trichotillomania (TTM) severity, the relationships between TTM severity and anxiety dimensions (i.e., cognitive and somatic anxiety) are unknown.

Internet-delivered, family-based treatment for early-onset OCD: A pilot randomized trial.

Objective: Despite advances in supported treatments for early onset obsessive-compulsive disorder (OCD), progress has been constrained by regionally limited expertise in pediatric OCD. Videoteleconferencing (VTC) methods have proved useful for extending the reach of services for older individuals, but no randomized clinical trials (RCTs) have evaluated VTC for treating early onset OCD.

Method: RCT comparing VTC-delivered family based cognitive-behavioral therapy (FB-CBT) versus clinic-based FB-CBT in the treatment of children ages 4-8 with OCD (N = 22).

Adult picky eaters with symptoms of avoidant/restrictive food intake disorder: comparable distress and comorbidity but different eating behaviors compared to those with disordered eating symptoms.

Background: One presentation of Avoidant/Restrictive Food Intake Disorder (ARFID) is characterized by picky eating, i.e., selective eating based on the sensory properties of food.

DSM-5 Trichotillomania: Perception of Adults With Trichotillomania After Psychosocial Treatment.

Objective: Trichotillomania (TTM) is associated with significant embarrassment and is viewed negatively by others. A potentially important outcome variable that is often overlooked in treatment for TTM is appearance and social perception.

Method: The present study tested whether participants in a randomized controlled trial (RCT) of psychotherapy for TTM are viewed more positively by others.

Factor analysis of the Milwaukee Inventory for Subtypes of Trichotillomania-Adult Version.

The Milwaukee Inventory for Subtypes of Trichotillomania-Adult Version (MIST-A; Flessner et al., 2008) measures the degree to which hair pulling in Trichotillomania (TTM) can be described as "automatic" (i.e.

Dental Fear and Avoidance in Treatment Seekers at a Large, Urban Dental Clinic.

Purpose: The prevalence and correlates of dental fear have been studied in representative population studies, but not in patients presenting for dental treatment. We hypothesized that dental fear among patients presenting at a large, urban college of dentistry would be similar to that of the population (e.g.

Comorbidity and quality of life in adults with hair pulling disorder.

Hair pulling disorder (HPD; trichotillomania) is thought to be associated with significant psychiatric comorbidity and functional impairment. However, few methodologically rigorous studies of HPD have been conducted, rendering such conclusions tenuous. The following study examined comorbidity and psychosocial functioning in a well-characterized sample of adults with HPD (N=85) who met DSM-IV criteria, had at least moderate hair pulling severity, and participated in a clinical trial.

Hoarding in Children and Adolescents: A Review.

The diagnostic conceptualization of hoarding has recently changed, and yet the application of these changes to hoarding in youth remains to be clarified. In this review we examine the literature on hoarding in youth. We discuss issues related to the assessment of pediatric hoarding, and the nature of hoarding in youth.

Defining treatment response in trichotillomania: a signal detection analysis.

The Massachusetts General Hospital Hairpulling Scale (MGH-HPS) and the NIMH Trichotillomania Severity Scale (NIMH-TSS) are two widely used measures of trichotillomania severity. Despite their popular use, currently no empirically-supported guidelines exist to determine the degrees of change on these scales that best indicate treatment response. Determination of such criteria could aid in clinical decision-making by defining clinically significant treatment response/recovery and producing accurate power analyses for use in clinical trials research.

Residential treatment outcomes for adolescents with obsessive-compulsive disorder.

Objective: We examined outcomes from a residential treatment program emphasizing exposure and response prevention (ERP) to determine if the typically robust response to this treatment in outpatient settings extends to patients treated in this unique context.

Method: One hundred and seventy-two adolescents with primary Obsessive-compulsive disorder (OCD) completed measures at admission and discharge. Almost all (92.
