Family Accommodation in Pediatric Obsessive–Compulsive Disorder

Despite the importance of the family in the treatment of pediatric obsessive–compulsive disorder (OCD), relatively little empirical attention has been directed to family accommodation of symptoms. This study examined the relations among family accommodation, OCD symptom severity, functional impairment, and internalizing and externalizing behavior problems in a sample of 57 clinic-referred youth 7 to 17 years old (M = 12.99 ± 2.54) with OCD. Family accommodation was a frequent event across families. Family accommodation was positively related to symptom severity, parent-rated functional impairment (but not child-rated impairment), and externalizing and internalizing behavior problems. Family accommodation mediated the relation between symptom severity and parent-rated functional impairment.

Psychometric evaluation of the Children's Yale–Brown Obsessive-Compulsive Scale

This study evaluated the psychometric properties of the Childrens Yale-Brown Obsessive-Compulsive Scale (CY-BOCS). A total of 61 children and adolescents, aged 4-18 years, who were diagnosed with obsessive-compulsive disorder (OCD) participated. Thirty-seven of these children also participated in a second CY-BOCS administration by the same rater an average of 41 days later. Good internal consistency and test-retest reliability were found for the CY-BOCS Obsession and Compulsion Severity Scores and the Total Score. CY-BOCS scores demonstrated strong correlations with clinician-rated measures of impairment, obsessions, and compulsions. In addition, CY-BOCS scores were moderately related to measures of depression, aggressive behavior, and symptoms of attention deficit hyperactivity disorder, but were not significantly related to clinician ratings of tics or self-reports of general anxiety. Findings suggest that the CY-BOCS is a reliable and valid instrument for the assessment of childhood obsessions and compulsions.

Impact of Comorbidity on Cognitive-Behavioral Therapy Response in Pediatric Obsessive-Compulsive Disorder.

OBJECTIVE To examine the impact of psychiatric comorbidity on cognitive-behavioral therapy response in children and adolescents with obsessive-compulsive disorder. METHOD Ninety-six youths with obsessive-compulsive disorder (range 7-19 years) received 14 sessions of weekly or intensive family-based cognitive-behavioral therapy. Assessments were conducted before and after treatment. Primary outcomes included scores on the Childrens Yale-Brown Obsessive-Compulsive Scale, response rates, and remission status. RESULTS Seventy-four percent of participants met criteria for at least one comorbid diagnosis. In general, participants with one or more comorbid diagnoses had lower treatment response and remission rates relative to those without a comorbid diagnosis. The number of comorbid conditions was negatively related to outcome. The presence of attention-deficit/hyperactivity disorder and disruptive behavior disorders was related to lower treatment response rates, and the presence of disruptive behavior disorders and major depressive disorder were related to lower remission rates. CONCLUSIONS The presence of a comorbid disorder, particularly disruptive behavior, major depressive, and attention-deficit/hyperactivity disorders, has a negative impact on treatment response. Assessing for psychiatric disorders before treatment entry and treating these comorbid conditions before or during cognitive-behavioral therapy may improve final outcome. Comorbid anxiety or tic disorders do not seem to negatively affect response.

Decreased Family Accommodation Associated with Improved Therapy Outcome in Pediatric Obsessive-Compulsive Disorder

Pediatric obsessive-compulsive disorder (OCD) is a chronic, disabling condition that affects both patients and their families. Despite the identification of efficacious treatments (e.g., cognitive-behavioral therapy and selective serotonin reuptake inhibitor medications), not all patients respond fully. The purpose of the present study was to examine whether the amount of family accommodation provided to pediatric patients with OCD is associated with treatment outcome, and whether decreases in accommodation are associated with improved outcome. The sample consisted of 49 youths (6-18 years of age), who participated in 14 sessions of family-based cognitive-behavioral therapy for OCD, and their parents. Participants completed measures at pretreatment and posttreatment. Results indicate that family accommodation was prevalent among families of pediatric patients with OCD and that such accommodation was associated with symptom severity at pretreatment. In addition, decreases in family accommodation during treatment predicted treatment outcome, even when controlling for pretreatment OCD severity-impairment. Results suggest that the level of accommodation provided by the family may indicate an important obstacle to, or predictor of, treatment outcome in pediatric OCD. Directions for future research are discussed.

D-cycloserine does not enhance exposure-response prevention therapy in obsessive-compulsive disorder

Obsessive–compulsive disorder is a common, chronic, and oftentimes disabling disorder. The only established first-line treatments for obsessive–compulsive disorder are exposure and response prevention therapy and the serotonin reuptake inhibitors. Many patients do not experience complete symptom resolution with either modality and require augmentation approaches. Recent animal and clinical data suggest that D-cycloserine, a partial agonist that acts at the strychnine-insensitive glycine-recognition site of the N-methyl-D-aspartate receptor complex, may enhance extinction learning that occurs in exposure-based psychotherapies. Given this, this study examined if D-cycloserine (250 mg) enhances the overall efficacy and rate of change of exposure and response prevention therapy for adult obsessive–compulsive disorder. Participants were 24 adults meeting Diagnostic and Statistical Manual of Mental Disorders-IV criteria for obsessive–compulsive disorder. The study design was a randomized, double-blinded, placebo-controlled augmentation trial examining exposure and response prevention therapy+D-cycloserine versus exposure and response prevention therapy+placebo. All patients received 12 weekly sessions of exposure and response prevention treatment. The first session involved building a ritual hierarchy and providing psychoeducation about obsessive–compulsive disorder. The second session involved a practice exposure. Sessions 3–12 involved exposure and response prevention exercises. D-cycloserine or placebo (250 mg) was taken 4 h before every session. No significant group differences were found across outcome variables. The rate of improvement did not differ between groups. The present results fail to support the use of D-cycloserine with exposure and response prevention therapy for adult obsessive–compulsive disorder. As this study is the first to explore this question and a number of methodological issues must be considered when interpreting the findings, the conclusions that may be drawn from our results are limited.

A Preliminary Study of D-Cycloserine Augmentation of Cognitive-Behavioral Therapy in Pediatric Obsessive-Compulsive Disorder

BACKGROUND Research on the neural circuitry underlying fear extinction has led to the examination of D-cycloserine (DCS), a partial agonist at the N-methyl-D-aspartate receptor in the amygdala, as a method to enhance exposure therapy outcome. Preliminary results have supported the use of DCS to augment exposure therapy in adult anxiety disorders; however, no data have been reported in any childhood anxiety disorder. Thus, we sought to preliminarily examine whether weight-adjusted DCS doses (25 or 50 mg) enhanced the overall efficacy of cognitive-behavioral therapy (CBT) for pediatric obsessive-compulsive disorder (OCD). METHOD Participants were 30 youth (aged 8-17) with a primary diagnosis of OCD. The study design was a randomized, double-blinded, placebo-controlled augmentation trial examining CBT + DCS versus CBT + Placebo (15 youth per group). All patients received seven exposure and response prevention sessions paired with DCS or placebo taken 1 hour before sessions. RESULTS Although not significantly different, compared with the CBT + Placebo group, youth in the CBT + DCS arm showed small-to-moderate treatment effects (d = .31-.47 on primary outcomes). No adverse events were recorded. CONCLUSIONS These results complement findings in adult OCD and non-OCD anxiety disorders and provide initial support for a more extensive study of DCS augmentation of CBT among youth with OCD.

Clinical predictors of response to cognitive-behavioral therapy for obsessive–compulsive disorder

This paper reviews predictors of treatment response in open and controlled trials of cognitive-behavioral therapy for obsessive-compulsive disorder (OCD). We focus on demographic characteristics, aspects of OCD symptoms, comorbidity, family factors, cognitive influences, and treatment-specific characteristics as predictor variables. Although inconsistent findings characterize much of the literature, several relatively consistent and salient predictors have emerged, including symptom severity, symptom subtype, severe depression, the presence of comorbid personality disorders, family dysfunction, and the therapeutic alliance. Implications of findings and recommendations for future research are discussed.

Psychosocial adaptation of fathers of children with autism, down syndrome, and normal development

Fathers have been largely neglected in previous research of families of autistic children. We compared fathers of 20 autistic, 20 Down syndrome, and 20 developmentally normal children on several measures of psychosocial adaptation. Groups were matched on childs adaptive behavior age equivalent, gender, birth order, family size, and SES. The three groups differed significantly on measures of intrapersonal and family functioning but not on social-ecological variables. Fathers of children with autism or Down syndrome reported more frequent use of wish-fulfilling fantasy and information seeking as coping strategies as well as more financial impact and disruption of family activities than did fathers of developmentally normal children. There were few significant differences between fathers of children with autism and those of children with Down syndrome. These results suggest that fathers adapt relatively well to the demands associated with raising a child with a developmental disability.

Reliability and validity of the yale global tic severity scale

To investigate the reliability and validity of the Yale Global Tic Severity Scale (YGTSS), 28 youth aged 6 to 17 years with Tourettes syndrome (TS) participated in the study. Data included clinician reports of tics and obsessive-compulsive disorder (OCD) severity, parent reports of tics, internalizing and externalizing problems, and child reports of depression and anxiety. All children participated in a 2nd YGTSS administration by the same rater 48 days later. Good internal consistency and stability were found for the YGTSS scores. YGTSS scores demonstrated strong correlations with parent-rated tic severity (r = .58-.68). YGTSS scores were not significantly related to measures of clinician ratings of OCD severity (r = .01-.15), parent ratings of externalizing and internalizing behavior (r = -.07-.20), and child ratings of depression (r = .02-.26) and anxiety (r = -.06 -.28). Findings suggest that the YGTSS is a reliable and valid instrument for the assessment of pediatric TS.

Quality of life in youth with Tourette's syndrome and chronic tic disorder.

This study sought to examine quality of life (QoL) in clinic-referred children and adolescents (n = 59, M age = 11.4±2.6 years) with a chronic tic disorder. The QoL scores for tic patients were lower than for healthy controls but higher than for the psychiatric sample on the majority of domains. Childrens self-reported QoL scores and a measure of tic severity were moderately and inversely correlated. Parent reports of their childs QoL were weakly related to tic severity. Correlations between parent and child ratings of QoL for children ages 8 to 11 years were generally higher than those for youth ages 12 to 17 years. Finally, externalizing behavior moderated the relations between tic severity and parent-rated QoL, such that tic severity was significantly associated with parent-rated QoL for children with below average externalizing symptoms but not for children 3with above average externalizing symptoms.
