Adaptive, emotional, and family functioning of children with obsessive-compulsive disorder and comorbid attention deficit hyperactivity disorder

OBJECTIVE: The purpose of the study was to examine adaptive, emotional, and family functioning in a well-characterized group of children and adolescents with obsessive-compulsive disorder (OCD) and to evaluate the influence of comorbid attention deficit hyperactivity disorder (ADHD) on the levels of impairment in various functional domains. METHOD: The study group included 287 children and adolescents (191 boys, 96 girls) ages 7-18 years. Fifty-six subjects had a diagnosis of OCD only, 43 had both OCD and ADHD, 95 had ADHD, and 93 were unaffected comparison children. Best estimate DSM-IV diagnoses were assigned on the basis of structured interviews and clinical ratings. The children's functioning was evaluated with a comprehensive battery of well-established, standardized measures, including the Vineland Adaptive Behavior Scales, parents' ratings of social and family functioning, and children's self-reports of emotional adjustment. RESULTS: The children with OCD only were more impaired than were unaffected comparison subjects in most areas of adaptive functioning and emotional adjustment. Children with OCD plus ADHD had additional difficulties in social functioning, school problems, and self-reported depression. Impairment in daily living skills, reduced number of activities, and self-reported anxiety were uniquely associated with the diagnosis of OCD. Family dysfunction was associated with ADHD but not with OCD. CONCLUSIONS: Children and adolescents with OCD are impaired in multiple domains of adaptive and emotional functioning. When comorbid ADHD is present, there is an additional burden on social, school, and family functioning.     

Childhood obsessive compulsive disorder: a two-year prospective follow-up of a community sample

A 2-year prospective follow-up of a community-based sample of adolescents previously diagnosed as having obsessive compulsive disorder (OCD) or "obsessive compulsive spectrum" disorder and a control sample was completed by clinicians experienced with OCD but blind to prior diagnosis. An initial diagnosis of OCD or "other psychiatric disorder with OC features" was most likely to predict a diagnosis of OCD at follow-up. Subclinical OCD at baseline did not strongly predict continuing psychopathology. A prior diagnosis of obsessive-compulsive personality predicted continued obsessive-compulsive symptoms but its relationship to OCD remains obscure.     

Neuropsychological performance in children and adolescents with obsessive-compulsive disorder and influence of clinical variables.

BACKGROUND: Several studies have found impairment in visual memory and visual organization in adults with obsessive-compulsive disorder (OCD), but little is known about the neuropsychological profile of children and adolescents with this disorder. The influence of clinical variables such as age, severity of obsessive-compulsive symptomatology, depressive symptomatology, and pharmacological treatment on cognitive performance in these patients has not been thoroughly studied. METHODS: A neuropsychological battery designed for this study was administered to 35 patients with DSM-IV-TR diagnosis of OCD without psychiatric comorbidity aged between 7 and 18 years and 35 gender- and age-matched healthy subjects. RESULTS: Children and adolescents with OCD performed significantly worse on verbal and visual memory and velocity. When depressive symptomatology was controlled, impairment in visual memory, visual organization, and velocity again was found, but impairment in verbal memory was not. Neuropsychological impairment was not related to age, obsessive-compulsive severity, and pharmacological treatment. CONCLUSIONS: Children and adolescents with OCD without psychiatric comorbidity with acute illness show impairment in visual memory, visual organization, and velocity, similar to adults. The influence of depressive symptomatology is important in cognitive performance. No relation was found between neuropsychology and age, severity of obsessive-compulsive symptomatology, or pharmacological treatment in this study.     

The children's Yale-Brown obsessive-compulsive scale: psychometric properties of child- and parent-report formats

The children's Yale-Brown obsessive-compulsive scale (CY-BOCS) is a commonly used, psychometrically sound clinician-rated instrument of pediatric obsessive-compulsive disorder (OCD) severity. Given the relatively direct rating format and potential benefits of alternative versions that could be easily administered to patients and parents, we developed and examined the psychometric properties of child- and parent-report formats of the CY-BOCS severity items. A total of 53 children and adolescents (8-17 years old) with OCD and their parents was administered the CY-BOCS, children's Yale-Brown obsessive-compulsive scale-child report (CY-BOCS-CR), children's Yale-Brown obsessive-compulsive scale-parent report (CY-BOCS-PR), and other measures of obsessive-compulsive symptoms, internalizing, and externalizing symptoms. In general, reliability and convergent and divergent validity of the CY-BOCS-CR/PR were satisfactory. Psychometric properties for the CY-BOCS-CR in those children and adolescents with externalizing behavior problems were lower relative to those without externalizing problems. Exploratory factor analyses identified a two-factor structure in both measures comprised of disturbance and severity factors. This study provides preliminary support for the use of child- and parent-report versions of the CY-BOCS.     

Perfectionism and Peer Relations Among Children with Obsessive-compulsive Disorder

The study examined perfectionism, symptoms of obsessive-compulsive disorder (OCD) and depression, and peer relationships among a clinical sample of 31 youth (age␣range 7–18 years) diagnosed with OCD. Using a correlational design, perfectionistic beliefs accounted for significant variance in OCD symptoms, depressive symptoms, and difficulties in peer relationships for children with OCD. One dimension of perfectionism, sensitivity to mistakes, was the most salient maladaptive aspect of perfectionism for this sample whereas another dimension, contingent self-esteem, emerged as the most salient adaptive dimension. Implications are discussed regarding the diagnosis, treatment, and developmental course of OCD among children and adolescents. Portions of this study were presented at the 114th Annual Convention of the American Psychological Association (New Orleans, LA).     

Cognitions in children with OCD

Cognitive theory, postulates that dysfunctional cognitions play a maintaining or even aetiological role in obsessive-compulsive disorder (OCD). In this study it was hypothesised that if distorted cognitions play a central role in OCD, there should be a relation between cognitive measures and the severity of the obsessive-compulsive symptoms in a childhood OCD sample. A group of 39 children and adolescents with a primary diagnosis OCD was measured on the CY-BOCS, and on the cognitive questionnaires the MTQ, and the CATS. The findings suggest no relation between the severity of the OCD and magical thinking. In the younger group aged 8–12 years (n = 18) no relations with any negative thoughts were found. In the older group, aged 13–18 years (n = 21), relations between the CY-BOCS Obsession scale and the CATS subscales Physical Threat, Social Threat and Personal Failure were found. Compared to a previously published community sample, the MTQ scores in the present sample are lower. The CATS scores for the OCD sample were found to be lower than most clinical comparison groups, which is especially true for the CATS Hostility subscale. Issues about criterion contamination and explanatory hypothesis about the age specific relation are addressed.     

Comorbidity of obsessive-compulsive disorder and attention-deficit/hyperactivity disorder in referred children and adolescents

OBJECTIVE: The aim of this study was to explore whether comorbid attention-deficit/hyperactivity disorder (ADHD) affects the clinical expression and outcome of obsessive-compulsive disorder (OCD) in a clinical sample. METHOD: A consecutive series of 94 children and adolescents (mean age, 13.6 +/- 2.8 years) with current diagnosis of OCD were included in the study. Twenty-four (25.5%) patients were diagnosed as having a comorbid ADHD. Subjects with OCD plus ADHD were compared with subjects with OCD but without ADHD. RESULTS: Comorbid ADHD with OCD was significantly associated with a higher rate of males, an earlier onset of OCD, a greater psychosocial impairment, and a heavier comorbidity, namely, with bipolar disorder, tic disorder, and oppositional defiant disorder/conduct disorder. Phenomenology of obsessions and compulsions and outcome were not affected by ADHD comorbidity. CONCLUSIONS: A screening for ADHD should be performed in patients with OCD, as these patients and their parents are frequently not aware that the impairment may be partly due to a comorbid ADHD.     

Fluoxetine treatment of children and adolescents with Tourette's and obsessive compulsive disorders: preliminary clinical experience

Fluoxetine hydrochloride is the first selective serotonin uptake inhibitor introduced commercially in the United States. This report describes preliminary clinical experience with fluoxetine in 10 children and adolescents, aged 8 to 15 years, with primary obsessive compulsive disorder (OCD) or Tourette's syndrome (TS) plus OCD. In general, fluoxetine, which was administered from 4 to 20 weeks at a dosage of 10 or 40 mg per day, was well tolerated. Adverse effects included behavioral agitation/activation in four patients and mild gastrointestinal symptoms in two patients. No abnormalities were noted in the seven children who had follow-up EKGs. Five of the 10 patients (50%) were considered responders; their obsessive-compulsive symptoms decreased substantially during treatment with fluoxetine. Responder rates were similar in the primary OCD (two of four, 50%) and TS + OCD (three of six, 50%) groups. In conclusion, short-term fluoxetine administration appears to be safe in children and adolescents. Placebo-controlled trials are needed to further assess the efficacy of fluoxetine.     

Impulse-control disorders in children and adolescents with obsessive-compulsive disorder

The aim of this study was to examine current prevalences, clinical correlates and patterns of co-occurrence of impulse-control disorders (ICDs) in children and adolescents with obsessive-compulsive disorder (OCD). We examined rates and clinical correlates of comorbid ICDs in 70 consecutive child and adolescent subjects with lifetime DSM-IV OCD (32.9% females; mean age = 13.8 ± 2.9 years). Comorbidity data were obtained with structured clinical interviews using DSM-IV criteria. OCD severity was assessed with the Child Yale-Brown Obsessive-Compulsive Scale. All variables were compared in OCD subjects with and without current ICDs. 12 (17.1%) subjects met criteria for a current ICD. Pathological skin picking and compulsive nail biting were the most common ICDs with current rates of 12.8% and 10.0%, respectively. OCD subjects with current ICDs were significantly more likely to have a co-occurring tic disorder (66.7% vs. 20.7%). Although having an ICD was associated with greater numerical scores of OCD symptomatology, these differences were not statistically significant. There were no sex-specific patterns of ICD occurrence in children and adolescents with OCD. Certain ICDs are common among children and adolescents with OCD. Better identification of ICDs in children and adolescents with OCD is needed, as are empirically validated treatments for youth with co-occurring ICDs.     

Classification of obsessive-compulsive disorder in childhood and adolescence

OBJECTIVE: In child and adolescent psychiatry the validation of the diagnosis must be seen in the context of development. Comparing different diagnostic formulations DSM-IV and ICD-10-DCR in a clinical sample of children and adolescents suffering from obsessive-compulsive disorder (OCD) and their validation on external criteria represent such a heuristic approach. METHOD: We investigated 61 children seen consecutively in a specialized out-patient clinic for OCD. All of them were assessed by the International Diagnostic Checklists (IDCL). Diagnosis and diagnostic certainty were validated regarding age, age of onset and duration of illness. RESULTS: The agreement between the two diagnostic systems was low. The diagnostic stability of ICD-10-DCR was highly dependent on age, whereas that of the criteria DSM-IV did not depend on age and almost all subjects could be diagnosed definitely. CONCLUSION: This study suggests that the DSM-IV criteria are superior to that of ICD-10-DCR for diagnosing OCD in children and younger adolescents.     

Pituitary volume in pediatric obsessive-compulsive disorder.

BACKGROUND: Abnormalities in the limbic-hypothalamic-pituitary-adrenal (LHPA) axis have been implicated in the pathogenesis of obsessive-compulsive disorder (OCD). To our knowledge, however, no prior study has measured pituitary gland volume in OCD. METHODS: Volumetric magnetic resonance imaging studies were conducted in 31 psychotropic drug-na?ve children (10 boys, 21 girls) aged 8-17 years and 31 case-matched healthy comparison subjects. RESULTS: Pituitary volume was significantly smaller in patients with OCD as compared with healthy control subjects (11% smaller). Smaller pituitary volume in patients with OCD was associated with increased compulsive but not obsessive symptom severity. Boys with OCD had smaller pituitary gland volumes compared with control boys (20% smaller). No significant differences in pituitary volume were observed between girls with OCD and control girls. Boys with OCD had significantly smaller pituitary volumes than girls with OCD (31% smaller), whereas control boys also had smaller pituitary gland volumes compared with control girls (21% smaller). CONCLUSIONS: These findings provide new evidence of reduced pituitary volume in pediatric OCD that seems to be more prominent in male patients. The observed alterations in pituitary volume are consistent with neuroendocrine studies that have reported abnormalities in the LHPA axis in OCD.     

Childhood obsessive-compulsive disorder presenting as schizophrenia spectrum disorders

Obsessive compulsive disorder (OCD) is a highly heterogeneous disorder, presenting with a wide array of symptoms. Sometimes, OCD can appear to be psychotic in nature, with periods of loss of insight or the emergence of paranoid ideas. Likewise, individuals with schizophrenia spectrum disorders (SSDs), including schizophrenia or schizo-affective disorder, can have obsessive-compulsive or "obsessive-compulsive like" symptoms. The complexities of differentiating obsessive-compulsive symptoms from true psychotic symptoms have been recognized in adults. However, in the child and adolescent OCD literature, this has just begun to be explored. In children, limited insight regarding their obsessions and compulsions often makes it more difficult to differentiate OCD from psychotic disorders, including schizophrenia. This report describes 2 adolescents who were initially diagnosed with "difficult-to-treat" SSDs, leading to the use of third-line antipsychotic treatments such as clozapine. Once the core symptoms were recognized as obsessions and compulsions, and appropriately treated, the apparent "psychosis" resolved and did not return over extended follow up. Awareness of the possibility of OCD presenting as if it were a schizophrenia spectrum disorder can facilitate proper diagnosis and treatment.     

Cerebral activation in children and adolescents with obsessive-compulsive disorder before and after treatment: a functional MRI study

BACKGROUND: Structural and functional fronto-striatal abnormalities are involved in the pathophysiology of obsessive-compulsive disorder (OCD). The aims of the present study were: (a) to investigate possible regional brain dysfunction in premotor cortico-striatal activity in drug-na?ve children and adolescents with OCD; (b) to correlate brain activation with severity of obsessive-compulsive symptomatology; and (c) to detect possible changes in brain activity after pharmacological treatment. METHOD: Twelve children and adolescents (age range 7-18 years; seven male, five female) with DSM-IV obsessive-compulsive disorder and twelve healthy subjects matched for age, sex and intellectual level were studied. Functional magnetic resonance imaging data were obtained during the performance of simple and complex sequences. RESULTS: Comparing the complex motor condition with the simple control condition, both patients and controls showed a pattern of cerebral activation involving the fronto-parietal cortex and basal ganglia. Compared with controls, OCD patients presented significantly higher brain activation bilaterally in the middle frontal gyrus. After 6 months of pharmacological treatment and with clear clinical improvement, activation in the left insula and left putamen decreased significantly. CONCLUSION: In a paediatric OCD sample that was treatment na?ve and without another psychiatric disorder we showed hyperactivation of the circuits that mediate symptomatic expression of OCD. The cerebral activation decreases after treatment and clinical improvement.     

Treatment benefit and the risk of suicidality in multicenter, randomized, controlled trials of sertraline in children and adolescents

OBJECTIVE: The aim of this study was to examine the balance between the benefits of treatment and the risk of suicidality in children and adolescents in multicenter, randomized, controlled trials of sertraline versus placebo. METHOD: The published literature was searched for multicenter, randomized, placebo-controlled trials of sertraline for pediatric mental disorders. Four trials were identified: Two (pooled) in pediatric major depressive disorder (MDD; Wagner 2003) and two in obsessive-compulsive disorder (OCD; March et al. 1998; POTS Team 2004). Using intent-to-treat (ITT) analysis populations, the authors calculated the number needed to treat (NNT) for response and remission and the number needed to harm (NNH) for suicidality, and their ratio, for each clinical trial. RESULTS: NNTs ranged from 2 to 10, indicating clinically meaningful benefits. Benefit was greater for OCD than for MDD, and for adolescents as compared with children in MDD. No age effect was apparent for OCD. Suicidality was reported in 8 patients (5 assigned to sertraline and 3 assigned to placebo). All but 1 (a placebo-treated patient in the Pfizer OCD trial) were enrolled in the sertraline MDD trial. The NNH for suicidality in MDD was 64. Treatment emergent suicidality was more common in children (NNH 28.7) than in adolescents (NNH 706.3). Because no patient developed suicidality in sertraline-treated OCD patients, the NNH for sertraline in OCD approaches infinity. CONCLUSIONS: With the stipulation that doctor and patient preferences necessarily play a critical role in the choice of treatment, NNT to NNH ratios indicate a positive benefit-to-risk ratio for sertraline in adolescents with MDD and in patients of all ages with OCD.     

Parental psychopathology in child and adolescent obsessive-compulsive disorder

Purpose To identify the lifetime prevalence of obsessive-compulsive disorder (OCD) and other psychiatric diagnoses in parents of OCD pediatric patients as well as the frequency of onset of psychiatric disorders in the 6 months prior to evaluation. Methods Parents (n = 63) of 32 children and adolescents (20 males and 12 females; mean age of 13.3 ± 2.4) with OCD and parents of (n = 63) 32 age and sex-matched controls with no psychiatric diagnosis were examined. The semi-structured SCID-I was used to identify axis I psychiatric disorders and SCID-II to evaluate personality disorders. Results Mothers of patients had significantly more psychiatric diagnoses than control mothers (P = 0.001). Only parents of patients had diagnosis of OCD (P = 0.01) and psychiatric diagnosis (Adjustment Disorders, Major Depression, Anxiety Disorders) with onset during the 6 months prior to evaluation (P = 0.001). The duration of disease in children appeared to be related to development of morbidity in parents (P = 0.04). Parents of patients also showed a higher incidence of personality disorders (P = 0.01), in particular avoidant (6 versus 1 parents, P < 0.055) and obsessive-compulsive (9 versus 2 parents, P = 0.016) personality disorders. Conclusions The findings suggest that there may be an excess of psychopathology in parents of children with OCD as compared to parents of pediatric and non-psychiatric patients. Adjustment disorders with depressive and anxious symptoms are significantly more frequent in mothers of OCD children after the onset of the disease.     

Obsessive-compulsive disorder: admission patterns and diagnostic stability

All first-time admissions from 1970 to 1986 with obsessive-compulsive neurosis (OCD) (ICD-8 diagnosis number 300.39) or obsessive-compulsive personality disorder (OCPD) (ICD-8 diagnosis number 301.49) were analyzed based on an extract from the nationwide Psychiatric Case Register in Denmark. All patients with secondary diagnoses other than neurotic disorders or personality disorders (including “neuroses characterogenes”) were excluded from the study. A total of 284 patients were first-time admitted with a main diagnosis of OCD during the period. The sex ratio was 0.67 (males/females). A total of 126 were first-time admitted with a diagnosis of OCPD, with a sex ratio of 1.18 (males/females). Seventy-seven percent of the readmitted patients with a first-time diagnosis of OCD kept a diagnosis within the “emotional spectrum” at the last admission. About half kept OCD as a main diagnosis, whereas only 15% shifted to a severe psychiatric diagnosis such as schizophrenia or manic-depressive psychosis. Of the readmitted patients with OCPD. 13% later developed a diagnosis of manic-depressive psychosis.     

Obsessive-compulsive syndromes in older adolescents

OBJECTIVE: This report presents data on the prevalence of both obsessive-compulsive disorder (OCD) and subthreshold obsessive-compulsive syndrome (sOCS) in a representative sample of older male adolescents living in Piedmont, Italy. METHOD: A total of 1,883 recruits to the Italian Defence Force were interviewed using the OC portion of the Diagnostic Interview Schedule. A diagnosis of sOCS was made for individuals who had obsessive and/or compulsive symptoms but who failed to meet one of the severity criteria of impairment. RESULTS: The point and lifetime prevalence rates of OCD were 2.0% and 2.6%, respectively. In total, 12.3% of the subjects received a current diagnosis of sOCS. No differences were found when examining prevalence rates according to area of residence or occupational status of the subjects. CONCLUSION: Our findings suggest that OCD is as common in older male adolescents as it is in adults, and that sOCS, being commonly endorsed in a general adolescent population, may represent a normal phenomenon in older adolescents.     

Latent class analysis of organic aspects of obsessive-compulsive disorder in children and adolescents.

Organic aspects of obsessive-compulsive disorder (OCD) have previously been described and hypotheses of biological etiology have been suggested. Sixty-one patients, 8-17 years of age, who fulfilled the DSM-III criteria for OCD in a review of the records were compared with 117 matched control patients for organic features. The indicators chosen for an organic concept were neurological signs, more than mild electroencephalographic abnormality, specific developmental disorder and attention deficit, and their defining property of an organic concept was confirmed by latent class analysis. Neurological signs was the most sensitive and specific indicator. Significantly fewer OCD children than control patients were assigned to the organic class. Almost all the types of obsessive-compulsive symptoms were more related to the non-organic class. Such extroverted symptoms as behavioral problems and loss of temper were significantly more frequent in patients assigned to the latent organic class, whereas symptoms of phobia and depressive mood were more often present in patients belonging to the nonorganic class. No difference was found between OCD patients and controls as to frequency of birth complications. The findings do not support the evidence of OCD having signs of major cerebral disturbance found by conventional neuropediatric methods.     

Group A beta hemolytic streptococcal infections and obsessive-compulsive symptoms in a Turkish pediatric population

The purpose of the present study was to evaluate obsessive-compulsive disease (OCD) in Turkish Children who had group A beta hemolytic streptococcal (GABHS) infections and those who had not. Thirty-one children and adolescents (the study group) were compared with 28 children and adolescents. The Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) scores were rated between study group and control group. The mean score, obsession and compulsion scores of CY-BOCS in the study group were significantly higher than they were in the control group (P < 0.05). The GABHS infections should be assessed in the etiology of OCD in children. Considering GABHS infections may help the treatment of OCD.     

Principal components analysis of obsessive-compulsive disorder symptoms in children and adolescents.

BACKGROUND: Obsessive-compulsive disorder (OCD) has a broadly diverse clinical expression that may reflect etiologic heterogeneity. Several adult studies have identified consistent symptom dimensions of OCD. The purpose of this study was to conduct an exploratory principal components analysis of obsessive-compulsive (OC) symptoms in children and adolescents with OCD to identify improved phenotypes for future studies. METHODS: This study examined lifetime occurrence of OC symptoms included in the 13 symptom categories of the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS). Principal components analysis with promax rotation was performed on 231 children and adolescents with OCD and compared with results of similar adult studies. RESULTS: A four-factor solution emerged explaining 59.8% of symptom variance characterized by 1) symmetry/ordering/repeating/checking; 2) contamination/cleaning/aggressive/somatic; 3) hoarding; and 4) sexual/religious symptoms. All factors included core symptoms that have been consistently observed in adult studies of OCD. CONCLUSIONS: In children and adolescents, OCD is a multidimensional disorder. Symptom dimensions are predominantly congruent with those described in similar studies of adults with OCD, suggesting fairly consistent covariation of OCD symptoms through the developmental course. Future work is required to understand changes in specific symptom dimensions observed across the life span.
