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.

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).

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.

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.

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.

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.

Good modelling practice in applying computational fluid dynamics for WWTP modelling.

Computational fluid dynamics (CFD) modelling in the wastewater treatment (WWT) field is continuing to grow and be used to solve increasingly complex problems. However, the future of CFD models and their value to the wastewater field are a function of their proper application and knowledge of their limits. As has been established for other types of wastewater modelling (i.

An unusual inguinoscrotal hernia with renal involvement.

We present a case of a 74-year-old man who, while in intensive treatment unit for an upper gastrointestinal bleed, decompensated cardiac failure and concurrent pneumonia, was found to have a large right hydronephrotic pelvic kidney and bladder within the hernia. After discharge, he was medically optimised for 7 months before undergoing an elective open mesh repair of his hernia. During the procedure, drainage of a large hydrocoele was performed to facilitate reduction of the hernia.

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.

Examining DSM criteria for trichotillomania in a dimensional framework: implications for DSM-5 and diagnostic practice.

Background: Diagnosis of trichotillomania (TTM) requires meeting several criteria that aim to embody the core pathology of the disorder. These criteria are traditionally interpreted monothetically, in that they are all equally necessary for diagnosis. Alternatively, a dimensional conceptualization of psychopathology allows for examination of the relatedness of each criterion to the TTM latent continuum.

College students' perceptions of individuals with anorexia nervosa: irritation and admiration.

Background: Stigmatizing attitudes against anorexia nervosa (AN) may act as barriers to treatment.

Aims: Evaluated college students' perceptions of AN as compared to major depressive disorder (MDD).

Method: One-hundred two female undergraduates read vignettes describing targets with mild or severe MDD or AN, then rated biological, vanity, and self-responsibility attributions; feelings of admiration, sympathy, and anger; and behavioral dispositions toward coercion into treatment, imitation, and social distance.

Defining early positive response to psychotherapy: An empirical comparison between clinically significant change criteria and growth mixture modeling.

Several different approaches have been applied to identify early positive change in response to psychotherapy so as to predict later treatment outcome and length as well as use this information for outcome monitoring and treatment planning. In this study, simple methods based on clinically significant change criteria and computationally demanding growth mixture modeling (GMM) are compared with regard to their overlap and uniqueness as well as their characteristics in terms of initial impairment, therapy outcome, and treatment length. The GMM approach identified a highly specific subgroup of early improving patients.

Measuring the role of psychological inflexibility in Trichotillomania.

Psychological Inflexibility (PI) is a construct that has gained recent attention as a critical theoretical component of Acceptance and Commitment Therapy (ACT). PI is typically measured by the Acceptance and Action Questionnaire-II (AAQ-II). However, the AAQ-II has shown questionable reliability in clinical populations with specific diagnoses, leading to the creation of content-specific versions of the AAQ-II that show stronger psychometric properties in their target populations.

Discrepancy between parents and children in reporting of distress and impairment: Association with critical symptoms.

Background: We examined discrepant parent-child reports of subjective distress and psychosocial impairment.

Method: Parent-child pairs (N = 112 pairs) completed the Health Dynamics Inventory at intake for outpatient therapy.

Results: Average parent scores were significantly higher than average child scores on distress, impairment, and externalizing symptoms, but not internalizing symptoms.

Dose-effect relationship in routine outpatient psychotherapy: does treatment duration matter?

Objective: There is an ongoing debate concerning how outcome variables change during the course of psychotherapy. We compared the dose-effect model, which posits diminishing effects of additional sessions in later treatment phases, against a model that assumes a linear and steady treatment progress through termination.

Method: Session-by-session outcome data of 6,375 outpatients were analyzed, and participants were categorized according to treatment length.

Post-inpatient attrition from care "as usual" in veterans with multiple psychiatric admissions.

Disengagement from outpatient care following psychiatric hospitalization is common in high-utilizing psychiatric patients and contributes to intensive care utilization. To investigate variables related to treatment attrition, a range of demographic, diagnostic, cognitive, social, and behavioral variables were collected from 233 veterans receiving inpatient psychiatric services who were then monitored over the following 2 years. During the follow-up period, 88.

Predictors of rehospitalization in high-utilizing patients in the VA psychiatric medical system.

233 high-service-utilizing (HSU) psychiatric patients were recruited during an inpatient psychiatric treatment. They completed a questionnaire related to their treatment beliefs and were tracked via computerized medical records over 2 years. During the follow-up period, 79.

A naturalistic study of the associations between changes in alcohol problems, spiritual functioning, and psychiatric symptoms.

The study evaluated how spiritual and religious functioning (SRF), alcohol-related problems, and psychiatric symptoms change over the course of treatment and follow-up. Problem drinkers (n = 55, including 39 males and 16 females) in outpatient treatment were administered questionnaires at pretreatment, posttreatment, and follow up, which assessed two aspects of SRF (religious well-being and existential well-being), two aspects of alcohol misuse (severity and consequences), and two aspects of psychiatric symptoms (depression and anxiety). Significant improvements in SRF, psychiatric symptoms and alcohol misuse were observed from pretreatment to follow-up.

Dissemination strategies to improve implementation of the PHS smoking cessation guideline in MCH public health clinics: experimental evaluation results and contextual factors.

We report results from an experimental study that tested the effectiveness of dissemination interventions to improve implementation of smoking cessation guidelines in maternal and child public health clinics. We additionally examine individual clinic results for contextual explanations not apparent from the experimental findings alone. Twelve clinics in Illinois were randomized to three dissemination strategies: (i) core dissemination (provision of the 2000 Public Health System Clinical Practice Guideline and a tested smoking cessation program, including program supplies and training), (ii) core dissemination and access to telephone counseling and (iii) core dissemination, telephone counseling access and outreach visits to clinics.

Methodological background of decision rules and feedback tools for outcomes management in psychotherapy.

Systems to provide feedback regarding treatment progress have been recognized as a promising method for the early identification of patients at risk for treatment failure in outpatient psychotherapy. The feedback systems presented in this article rely on decision rules to contrast the actual treatment progress of an individual patient and his or her expected treatment response (ETR). Approaches to predict the ETR on the basis of patient intake characteristics and previous treatment progress can be classified into two broad classes: Rationally derived decision rules rely on the judgments of experts, who determine the amount of progress that a patient has to achieve for a given treatment session to be considered "on track.
