The aims of the present study were to examine OCD-related impairments in clinical cases of childhood OCD and to replicate and extend previous research on OCD-related impairments.MethodSixty-eight patients aged 8–17 years recruited from four child psychiatric outpatient clinics in Norway and Sweden with a confirmed DSM-IV diagnosis of OCD were included in the study. All patients and their parents were interviewed for diagnosis and comorbidity (KSADS),OCD symptoms and severity (CY-BOCS), and global impairment (CGAS). OCD-specific impairments were assessed by means of the Child OCD Impact Scale (COIS), a 58 item questionnaire with parallel parent and child versions.ResultsOverall, the majority of patients suffered from substantial impairments. The impact of OCD symptoms was found to be most severe at home, but impairments were also prominent in situations related to school and social settings.ConclusionsOur study supports findings of previous research suggesting multiple impacts of OCD symptoms on children’s psychosocial functioning. We conclude that impairment issues should be further addressed in future research to establish a better empirical basis for the understanding of different aspects of OCD-related impairment.

Research on obsessive–compulsive disorder (OCD) in children and adolescents has led to important developments with clinical implications as regards assessment and treatment. These developments have resulted in new guidelines and recommendations as to what is regarded to be an adequate treatment of the disorder. The objective of the present study was to examine if these developments have led to changes in the views on clinical management of childhood OCD among child psychiatry personnel in Norway. A national survey was conducted by means of a questionnaire addressing preferences and practices among clinicians in their assessment and management of OCD, the clinicians self-reported experienced treatment success, and need to develop clinical skills on assessing and treating childhood OCD. Seventy-nine clinicians (58.5%) responded. The results showed that cognitive/behavioural, family and medication approaches were preferred over psychodynamic and humanistic approaches in the management of OCD. The preferred cognitive/behavioural approach seems to be more cognitive than behavioural, and only one-third of clinicians reported frequent use of anxiety-provoking methods in treatment of childhood OCD. Clinicians that self-rated the Clinical Global Improvement Scale on their last treated OCD case indicated moderate treatment success. Because of low numbers of OCD cases in the clinics, the majority of clinicians are rated as inexperienced in the management of the disorder and results show a need for adequate training opportunities. It is concluded that clinicians have accommodated to recommended standards in the management of childhood OCD, but some results are contradictory and do not justify conclusive statements. The study needs to be supplemented by research focusing on more specific elements of the preferred treatments, thus narrowing the scope of the present study.

BackgroundThis paper describes and discusses the methodology of the Nordic long-term OCD-treatment study (NordLOTS). The purpose of this effectiveness study was to study treatment outcome of CBT, to identify CBT non- or partial responders and to investigate whether an increased number of CBT-sessions or sertraline treatment gives the best outcome; to identify treatment refractory patients and to investigate the outcome of aripiprazole augmentation; to study the outcome over a three year period for each responder including the risk of relapse, and finally to study predictors, moderators and mediators of treatment response.MethodsStep 1 was an open and uncontrolled clinical trial with CBT, step 2 was a controlled, randomised non-blinded study of CBT non-responders from step 1. Patients were randomized to receive either sertraline plus CBT-support or continued and modified CBT. In step 3 patients who did not respond to either CBT or sertraline were treated with aripiprazole augmentation to sertraline.ConclusionsThis multicenter trial covering three Scandinavian countries is going to be the largest CBT-study for paediatric OCD to date. It is not funded by industry and tries in the short and long-term to answer the question whether further CBT or SSRI is better in CBT non-responders.

Abstract Objective: The purpose of this study was to investigate whether the presence of tic disorder is negatively associated with sertraline (SRT) outcomes, but not with continued cognitive-behavioral therapy (CBT), in a sample of youth who were unresponsive to an initial full course of CBT. Methods: In the Nordic Long-Term OCD Study, children and adolescents with OCD who were rated as nonresponders to 14 weeks of open-label CBT were randomized to continued CBT (n=28) or SRT treatment (n=22) for an additional 16 weeks of treatment. We investigated whether the presence or absence of comorbid tic disorder moderated treatment outcomes on the Childrens Yale-Brown Obsessive Compulsive Scale (CY-BOCS). Results: Twelve out of 50 (24.0%) participants were diagnosed with comorbid tic disorder, with 7 receiving continued CBT and 5 receiving SRT, respectively. In patients without tic disorder, results showed no significant between-group differences on average CY-BOCS scores. However, in patients with comorbid tic disorder, those who received SRT had significantly lower average CY-BOCS scores than those who received continued CBT. Conclusions: Children and adolescents with OCD and comorbid tic disorder, who are nonresponders to an initial 14 week course of CBT, may benefit more from a serotonin reuptake inhibitor (SRI) than from continued CBT.

Over the past decade, an increasing body of research has been conducted on evidence-based psychological and psychiatric treatment for pediatric obsessive-compulsive disorder (OCD). Despite this improved understanding, however, these treatments are not being performed. This study descriptively examined the practices and views of school psychologists on the management of pediatric OCD. Two hundred twenty-seven clinicians responded to a survey adapted from previous work by Valderhaug, Gotestam, and Larsson. Results suggested that school psychologists preferred cognitive-behavioral, medical, and family/systemic orientations relative to psychodynamic and humanistic approaches. Although respondents reported an adherence to evidence-based treatment, only 7% reported using behavioral exposure. Many respondents reported only moderate treatment success and expressed an overwhelming need for further training in both the assessment and treatment of pediatric OCD. Our results suggest that school psychologists are not adequately trained to assess and provide evidence-based treatment of pediatric OCD.

Our aims were to examine: (1) classes of comorbid disorders in a sample of children and adolescents with Obsessive-Compulsive Disorder (OCD), (2) how these classes relate to obsessive-compulsive symptom dimensions, and (3) the extent to which obsessive-compulsive symptom dimensions predict Cognitive-Behavioral Therapy (CBT) outcome. Participants (N = 269) were assessed with the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL) and the Childrens Yale-Brown Obsessive-Compulsive Scale (CY-BOCS). Latent Class Analysis (LCA) was used to identify comorbidity classes. Regression analyses were used to evaluate symptom dimensions as predictors of treatment outcome and their relation to comorbidity classes. Comorbidity was included in the treatment outcome analyses as it can affect outcome. Comorbidity was best categorized by a three-class model and each class was distinctively correlated with the OCD symptom dimensions. Higher scores on the symmetry/hoarding factor increased the chance of responding to CBT by an odds ratio of 1.56 (p = 0.020) when controlled for age, gender, and comorbidity class. The harm/sexual factor (p = 0.675) and contamination/cleaning factor (p = 0.122) did not predict CBT outcome. Three clinically relevant comorbidity subgroups in pediatric OCD were identified. Patients who exhibited higher levels of symmetry/hoarding dimension were more prone to respond to CBT.
