Abstract
The psychometric properties of the Obsessive Compulsive Inventory-Child Version (OCI-CV) were examined in ninety-six youth with a primary/co-primary diagnosis of obsessive-compulsive disorder (OCD). A confirmatory factor analysis revealed an acceptable model of fit with factors consisting of doubting/checking, obsessing, hoarding, washing, ordering, and neutralizing. The internal consistency of the OCI-CV total score was good, while internal consistency for subscale scores ranged from poor to good. The OCI-CV was modestly correlated with obsessive-compulsive symptom severity on the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) Severity Scale, as well as with clinician-reported OCD severity. All OCI-CV subscales significantly correlated with the corresponding CY-BOCS Symptom Checklist dimension. The OCI-CV significantly correlated with child-reported depressive symptoms and OCD-related functional impairment, but was not significantly correlated with parent-reported irritability or clinician-reported overall functioning. Taken together, these data suggest the psychometric properties of the OCI-CV are adequate for assessing obsessive-compulsive symptom presence among youth with OCD.

Abstract
Chronic tic disorders (CTD) are characterized by motor and/or vocal tics. Existing data on the impact of tics in adulthood is limited by small, treatment-seeking samples or by data aggregated across adults and children. The current study explored the functional impact of tics in adults using a nationwide sample of 672 participants with a self-reported CTD. The impact of tics on physical, social, occupational/academic, and psychological functioning was assessed. Results suggested mild to moderate functional impairment and positive correlations between impairment and tic severity. Notable portions of the sample reported social or public avoidance and experiences of discrimination resulting from tics. Compared to previously reported population norms, participants had more psychological difficulties, greater disability, and lower quality of life. The current study suggests that CTDs can adversely impact functioning in adults and highlights the need for clinical interventions and systemic efforts to address tic-related impairments.

Abstract
OBJECTIVE To examine the efficacy of a modular cognitive-behavioral therapy (CBT) protocol relative to treatment as usual (TAU) among children with high-functioning autism spectrum disorders (ASD) and clinically significant anxiety. METHOD A total of 45 children (7-11 years of age) with high-functioning ASD and clinically significant anxiety were randomized to receive 16 sessions of weekly CBT or TAU for an equivalent duration. After screening, assessments were conducted at baseline, post-treatment, and 3-month follow-up. Raters were blind to treatment condition. RESULTS Youth receiving CBT showed substantial improvement relative to TAU on primary anxiety outcomes. Of 24 children randomized to the CBT arm, 18 (75%) were treatment responders, versus only 3 of 21 children (14%) in the TAU arm. Gains were generally maintained at 3-month follow-up for CBT responders. CONCLUSIONS Relative to usual care, CBT adapted for anxious youth with high-functioning ASD demonstrates large effects in reducing anxiety symptoms. This study contributes to the growing literature supporting adapted CBT approaches for treating anxiety in youth with ASD.

Abstract
Recent reports of autoantibodies that bind to neuronal surface receptors or synaptic proteins have defined treatable forms of autoimmune encephalitis. Despite these developments, many cases of encephalitis remain unexplained. We have previously described a basal ganglia encephalitis with dominant movement and psychiatric disease, and proposed an autoimmune aetiology. Given the role of dopamine and dopamine receptors in the control of movement and behaviour, we hypothesized that patients with basal ganglia encephalitis and other putative autoimmune basal ganglia disorders harboured serum autoantibodies against important dopamine surface proteins. Basal ganglia encephalitis sera immunolabelled live surface cultured neurons that have high expression of dopamine surface proteins. To detect autoantibodies, we performed flow cytometry cell-based assays using human embryonic kidney cells to express surface antigens. Twelve of 17 children (aged 0.4-15 years, nine males) with basal ganglia encephalitis had elevated immunoglobulin G to extracellular dopamine-2 receptor, compared with 0/67 controls. Immunofluorescence on wild-type mouse brain showed that basal ganglia encephalitis sera immunolabelled microtubule-associated protein 2-positive neurons in striatum and also in cultured striatal neurons, whereas the immunolabelling was significantly decreased in dopamine-2 receptor knock-out brains. Immunocytochemistry confirmed that immunoreactivity localized to the surface of dopamine-2 receptor-transfected cells. Immunoabsorption of basal ganglia encephalitis sera on dopamine-2 receptor-transfected human embryonic kidney cells decreased immunolabelling of dopamine-2 receptor-transfected human embryonic kidney cells, neurons and wild-type mouse brain. Using a similar flow cytometry cell-based assay, we found no elevated immunoglobulin G binding to dopamine 1, 3 or 5 receptor, dopamine transporter or N-methyl-d-aspartate receptor. The 12 dopamine-2 receptor antibody-positive patients with encephalitis had movement disorders characterized by parkinsonism, dystonia and chorea. In addition, the patients had psychiatric disturbance with emotional lability, attention deficit and psychosis. Brain magnetic resonance imaging showed lesions localized to the basal ganglia in 50% of the patients. Elevated dopamine-2 receptor immunoglobulin G was also found in 10/30 patients with Sydenham's chorea, 0/22 patients with paediatric autoimmune neuropsychiatric disorders associated with streptococcal infection and 4/44 patients with Tourette's syndrome. No dopamine-1 receptor immunoglobulin G was detected in any disease or control groups. We conclude that assessment of dopamine-2 receptor antibodies can help define autoimmune movement and psychiatric disorders.

Abstract
OBJECTIVE The purpose of this study was to examine child, parent, and clinician's consensus agreement on the Anxiety Disorders Interview Schedule, Child and Parent versions (ADIS-C/P) in a sample of children and adolescents with autism spectrum disorders (ASD). METHOD Youth with ASD (n=85; age range=7-17 years) and their parents were each administered the ADIS-C/P by a trained clinician. Consensus diagnoses were determined in a clinical conference using best estimate procedures that incorporated all available information. RESULTS Children and youth with ASD diagnoses generally showed poor diagnostic agreement with parents and clinical consensus, whereas parents showed good-to-excellent diagnostic agreement with clinical consensus diagnoses. Diagnostic agreement between parents and consensus was moderated by the specific ASD diagnosis. Otherwise, the pattern of relationships did not systematically differ as a function of age or externalizing comorbidity. CONCLUSIONS These data suggest that parent and youth agreement regarding the presence of clinical levels of anxiety is markedly poor among youth with ASD. Additionally, clinicians are likely to base their diagnostic impressions on parent report, placing minimal emphasis on child report.

Abstract
Exposure-based cognitive-behavioral therapy and serotonin reuptake inhibitor medications are efficacious treatment options for the management of pediatric obsessive-compulsive disorder. Despite established efficacy, many youths receiving either therapy remain symptomatic after acute treatment. Regardless of the rationale for persistent symptoms, a clear need emerges for treatment options that restore functioning efficiently to symptomatic youths. One innovative approach builds upon the identified role of NMDA receptors in the fear extinction process. Instead of breaking existing connections during fear extinction, new associations develop that eventually predominate over prior associations. Recent investigations have explored augmenting exposure-based cognitive-behavioral therapy with the NMDA partial agonist d-cycloserine, with preliminary results demonstrating expedited treatment gains and moderately larger effects above exposure and response prevention therapy alone. A large randomized clinical trial is underway to evaluate the efficacy and efficiency of this therapeutic combination in pediatric obsessive-compulsive disorder. Results from this trial may translate into improved management practices.

Abstract
OBJECTIVE Rage attacks have been documented in youth with varied psychiatric disorders, but few data have been reported on the clinical characteristics and correlates of rage attacks among children with obsessive-compulsive disorder (OCD). METHOD Participants were 86 children (ages 6-16 years) with a primary diagnosis of OCD. Patients and their primary caregiver were administered clinician-rated measures of obsessive-compulsive severity and rage severity. Children completed the Center for Epidemiologic Studies Depression Scale and the Child Sheehan Disability Scale-Child, whereas parents completed the Rage Attacks Questionnaire, Aberrant Behavior Checklist-Irritability Scale, Children's Affective Lability Scale, and Child Sheehan Disability Scale-Parent. RESULTS Rage was common among youth with OCD and was associated with varied clinical characteristics. Rage severity accounted for functional impairment beyond the influence of obsessive-compulsive symptom severity; however, these relations were explained by the impact of family accommodation. CONCLUSIONS These data suggest that rage attacks are relatively common, have a negative impact on illness presentation, and contribute to functional impairment above and beyond obsessive-compulsive symptom severity. Rage may contribute to family accommodation of symptoms, which may further affect obsessive-compulsive symptom severity and impairment.

Abstract
This study evaluated neurocognitive functioning in 26 youth with Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS) and primarily obsessive-compulsive disorder (OCD) symptoms. Marked impairment in visuospatial recall memory (as assessed using the Rey-Osterrieth Complex Figure Test) was observed in spite of average to above-average performance on academic and other neurocognitive measures. Group A beta-hemolytic Streptococcus titer elevations were associated with worse performance on tasks of neurocognitive and executive ability (Stroop Color-Word Interference Test), visuospatial memory, and fine motor speed (finger tapping) as well as elevated obsessive-compulsive symptom severity.

Abstract
Obsessive-compulsive disorder (OCD) is an anxiety disorder that affects between 1% to 2% of individuals and causes considerable impairment and disability. Although > 50% of individuals experience symptom onset in childhood, symptoms can continue to develop throughout adulthood. Accurate and timely assessment of clinical presentation is critical to limit impairment and improve prognosis. Presently, there are 2 empirically supported treatments available for OCD in children and adults, namely cognitive-behavioral therapy and pharmacotherapy with serotonin reuptake inhibitors. This article provides an introduction to the phenomenology, etiology, and clinical course of OCD. Assessment practices used to evaluate symptom severity are described, and evidence-based treatment options are reviewed, with appropriate distinctions drawn between children and adults. Finally, recommendations for assessment and treatment practices for OCD are explicated.

Abstract
Historically, trichotillomania (TTM) in young children (0-3 years old) generally has been considered to be a benign habit that is clinically distinct from the TTM seen in older children and adults. However, early childhood TTM can be an impairing pathological disorder that merits formal intervention. The present article reviews the extant literature on TTM in young children, highlighting the limited available phenomenological data. We discuss a behavioral approach to conceptualization and treatment, highlighting core intervention strategies in three early childhood TTM cases seen in our clinic. We conclude by discussing areas in need of further empirical attention.

Abstract
OBJECTIVE To explore associated clinical factors in children with pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS). STUDY DESIGN Children with tics, obsessive-compulsive disorder, or both (n=109) were examined with personal and family history, diagnostic interview, physical examination, medical record review, and measurement of baseline levels of streptococcal antibodies. RESULTS Significant group differences were found on several variables, such that children in whom PANDAS (versus without PANDAS) were more likely to have had dramatic onset, definite remissions, remission of neuropsychiatric symptoms during antibiotic therapy, a history of tonsillectomies/adenoidectomies, evidence of group A streptococcal infection, and clumsiness. CONCLUSION The identification of clinical features associated with PANDAS should assist in delineating risks for this subtype of obsessive-compulsive disorder/tics.

Abstract
Background: Many youth with tic disorders experience distress about having tics and how others may perceive them. Such symptoms are often more impairing and distressing than the tics themselves and negatively impact self-concept, psychosocial functioning, and quality of life. Objective: Although there exist pharmacological and behavioral treatments that target the frequency and severity of tics, no intervention has been developed specifically to help youth with tics cope with their condition and limit associated functional impairment and distress. With this in mind, we report an intervention case series of eight youth (ages 8–16 years) supporting the initial efficacy of a cognitive-behavioral therapy program entitled “Living with Tics” that promotes coping and resiliency among youth with tics. Method: Eight youth with a principal diagnosis of a tic disorder (i.e., Tourette syndrome [N = 6]; Chronic Tic Disorder [N = 2]) and associated psychosocial impairment participated. Assessments were conducted at screening, pretreatment, and posttreatment by trained raters. Treatment consisted of 10 weekly individual psychotherapy session focused on improving coping with having tics. Results: Six of eight youth were considered treatment responders. On average, participants exhibited meaningful reductions in tic-related impairment, anxiety, and overall tic severity as well as improvements in self-concept and quality of life. Conclusions: These data provide preliminary evidence for conducting a larger controlled trial to examine the utility of the Living with Tics psychosocial intervention for promoting adaptive functioning among youth with tics.

Abstract
This study examines correlates of hoarding behaviors among nonclinical elderly adults, focusing upon hoarding cognitions, obsessive-compulsive symptoms, and measures of general psychopathology. Two hundred and sixty-nine adults aged 56-93 years (M=72.49 years) completed the Saving Inventory-Revised, Savings Cognitions Inventory-Revised, Obsessive Compulsive Inventory-Revised, Social Interaction Anxiety Scale, Penn State Worry Questionnaire, and Beck Depression Inventory. Our geriatric sample evidenced significantly greater severity of hoarding behaviors than did a younger community sample (24-72 years; M=44.4 years; Frost, Steketee, & Grishman, 2004). Within our sample, moderate correlations were found between hoarding behaviors and hoarding cognitions; however, controlling for obsessive-compulsive and depressive symptoms resulted in reduced-magnitude associations. As well, relationships between obsessive-compulsive symptoms and both hoarding behaviors and hoarding cognitions were generally strong, with most relationships diminishing after controlling for depressive symptoms. Associations between hoarding symptoms and symptoms of social anxiety, general worry, and depression were generally moderate. A significant regression model showed depressive symptoms explaining the most unique variance in hoarding behaviors. Findings confirm a relatively greater severity of hoarding behaviors in older adults (as compared to younger adults) and suggest that related psychopathology plays a critical role in hoarding expression among older adults. As well, the current study contributes to the ongoing investigation of the diagnostic categorization of compulsive hoarding.

Abstract
OBJECTIVE To examine the optimal Yale Global Tic Severity Scale (YGTSS) percent reduction and raw cutoffs for predicting treatment response among children and adolescents with tic disorders. METHOD Youth with a tic disorder (N=108; range=5-17 years) participated in several clinical trials involving varied medications or psychosocial treatment, or received naturalistic care. Assessments were conducted before and after treatment and included the YGTSS and response status on the Clinical Global Impressions-Improvement Scale (CGI-I). RESULTS A 35% reduction on the YGTSS total tic severity score or a YGTSS raw total tic severity score change of 6 or 7 points were the best indicators of clinical treatment response in youth with tic disorders. CONCLUSIONS A YGTSS total tic severity score reduction of 35% or a raw total tic severity score change of 6 or 7 appears optimal for determining treatment response. A consistent definition of treatment response on the YGTSS may facilitate cross-study comparability. Practitioners can use these values for treatment planning decisions (e.g., change medications, etc.).

Abstract
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.

Abstract
Tic disorders impact quality of life, but when they are co-occurring with attention-deficit/hyperactivity disorder, the combined impact takes a toll on psychosocial functioning and adds another layer of complexity to treatment approaches. A review of the current literature supports evidence of a unique relationship between comorbid attention-deficit/hyperactivity disorder and tic disorders, emphasizing the intricate phenotype and impairment associated with these co-occurring conditions. The complexity of these symptoms requires careful diagnosis and appropriate treatment as determined by the level of impairment and can include pharmacotherapy, behavioral interventions, or a combination of therapies. To achieve the greatest benefits in improving quality of life and eliminating further comorbidity, an ideal treatment plan would include a comprehensive evaluation as well as a hierarchical treatment approach involving education of the child, family, and teachers; careful medication management; and cognitive and behavioral training.

Abstract
The psychometric properties of the Leyton Obsessional Inventory-Child Version Survey Form (LOI-CV Survey Form) and the Short Leyton Obsessional Inventory-Child Version Survey Form (Short LOI-CV Survey Form) were examined in a clinical sample of 50 children and adolescents with obsessive-compulsive disorder (OCD). The internal consistency of the LOI-CV and Short LOI-CV Survey Forms were acceptable and poor, respectively (α=.79 and .65). The LOI-CV Survey Form was significantly and moderately correlated with child-rated OCD-related impairment, but was not significantly correlated with any other measures of OCD symptom frequency or severity, OCD-related impairment, global symptom severity, child reports of anxiety and depressive symptoms, and parent reports of children's obsessive-compulsive, internalizing, and externalizing symptoms. Modest support for the cognitive-behavioral treatment sensitivity of the LOI-CV Survey Form (Cohen's d=0.98) but not the Short LOI-CV Survey Form (Cohen's d=0.09) was demonstrated. Diagnostic sensitivity was poor for the LOI-CV Survey Form at both pre- (0.14) and post-treatment (0.06). Overall, these results suggest that the psychometric properties of the LOI-CV and Short LOI-CV Survey Forms are not adequate for use as a screening instrument or in assessing symptom severity in pediatric OCD.

Abstract
Termed pediatric autoimmune neuropsychiatric disorders associated with Streptococcus (PANDAS), these cases of childhood-onset obsessive compulsive disorder and tic disorders resemble the presentation of Sydenham chorea, in that they have an acute onset following a group A beta-hemolytic streptococcal infection (group A Streptococcus), with accompanying neurological signs, and an episodic or sawtooth course. Familial associations of this subgroup of patients remain understudied. This report provides phenotypic descriptions of three youth with PANDAS as well as their genetically identical siblings (in two cases of twins and one case of triplets). These cases highlight the potential for environmental influences for discordant presentations in genetically identical siblings. Despite identical genetics, presentations showed marked variation across siblings (from a full PANDAS presentation to asymptomatic). Further research into environmentally driven influences such as postinfectious molecular mimicry and epigenetic factors that may influence the manifestation of these pediatric neuropsychiatric disorders will promote our understanding of their prevention and treatment.

Abstract
This article discusses the nature and treatment of compulsive hoarding among children. We summarize the phenomenology of compulsive hoarding, including its clinical presentation, comorbidity with varied mental disorders, and associated impairment. The limited data on treatment outcome are presented along with a behavioral framework that we utilized to treat youth who hoard. Our approach is highlighted in the context of a case illustration of an 11-year-old girl suffering from compulsive hoarding and several comorbid mental health disorders. We conclude with recommendations for clinical work with this challenging and neglected population.

Abstract
This research aimed to provide clinicians and investigators with optimal treatment outcome criteria for accurately predicting response and remission in both research studies and clinical practice. Data from 153 adult OCD outpatients (ages 18-79) who had participated in a treatment outcome study were examined. Signal detection analysis was conducted to compare levels of Yale-Brown Obsessive Compulsive Scale (Y-BOCS) symptom percent reductions and post treatment absolute scores with Clinical Global Impression (CGI) ratings of symptom improvement and severity. Optimal cutoff criteria were based on sensitivity, specificity and efficiency and were assessed via the Quality Receiver Operating Characteristic curve. A Y-BOCS reduction of 45% was observed to be the most efficient for predicting response in research trials, whereas a reduction of 35% may be optimal for clinical use. A 55% Y-BOCS reduction was determined to be the optimal cutoff for predicting remission in both clinical and research settings. A Y-BOCS absolute raw score of 12 or less was optimal for predicting remission in a clinical setting and a raw score of 14 or below was most favorable in research trials. This research provides the first empirical contrast of optimal outcome criteria in OCD based on differing ideals of both research and practice.

Abstract
Habit-reversal training (HRT) has demonstrated efficacy in adults and in children above 9 years of age with tic disorders. However, less is known about the utility of this treatment with children younger than 9 years of age.This is alarming given that most children with tic disorders experience symptom onset before 9 years and that existing pharmacological treatments show modest efficacy, may have side effects, and may not be an acceptable intervention to parents. With this in mind, this case report documents the use of HRT with a 6-year-old female with pronounced and impairing motor tics. Throughout the course of the treatment (eight sessions) “Megan” showed improvement in her ability to control her symptoms. Furthermore, treatment gains and improved quality of life were maintained at follow-up. This case report suggests the utility of HRT for the treatment of tics in early childhood, with developmental considerations and the integration of family-based skills training.

Abstract
In recent years, much progress has been made in pharmacotherapy for pediatric obsessive-compulsive disorder (OCD) and chronic tic disorders (CTDs). What were previously considered relatively intractable conditions now have an array of efficacious medicinal (and psychosocial) interventions available at clinicians’ disposal, including selective serotonin reuptake inhibitors, atypical antipsychotics, and alpha-2 agonists. The purpose of this review is to discuss the evidence base for pharmacotherapy with pediatric OCD and CTDs with regard to efficacy, tolerability, and safety, and to put this evidence in the context of clinical management in integrated behavioral healthcare. While there is no single panacea for these disorders, there are a variety of medications that provide considerable relief for children with these disabling conditions.

Abstract
The present study aimed to assess the phenomenology and treatment sensitivity of insight, avoidance, indecisiveness, overvalued responsibility, pervasive slowness, and pathological doubting among youth with Obsessive-compulsive disorder (OCD) using the ancillary items on the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). These factors are believed to be relevant to the clinical presentation of youth with OCD but remain understudied. Eighty-nine youth with OCD were administered the CY-BOCS, including six subsidiary items aimed at the constructs of interest in this research. Participants also completed measures of OCD symptom clusters, depressive and anxious symptoms, externalizing/internalizing behavioral problems, and functional impairment. Associations between OCD symptom clusters and insight, avoidance, indecisiveness, overvalued responsibility, pervasive slowness, and pathological doubting are presented. Low insight, significant avoidance, indecisiveness, pervasive slowness and excessive sense of responsibility were all related to elevations in functional impairment. Clinical improvement in OCD severity was related to reductions in avoidance, doubting, and sense of responsibility. The six ancillary items of the CY-BOCS appear to be a practical and valid assessment of several constructs that are prognostically linked to cognitive-behavioral therapy outcomes in youth with OCD. Implications for clinicians are discussed.
