Is it time to change the gold standard of obsessive-compulsive disorder severity assessment? Factor structure of the Yale-Brown Obsessive-Compulsive Scale.

OBJECTIVES: The Yale-Brown Obsessive-Compulsive Scale has been considered the gold standard scale to assess obsessive-compulsive disorder severity. Previous studies using exploratory factor analysis and confirmatory factor analysis with this scale showed mixed findings in terms of factor structure and fit of models. Therefore, we used confirmatory factor analysis to compare different Yale-Brown Obsessive-Compulsive Scale models in a large sample aiming to identify the best model fit. METHODS: We assessed adult obsessive-compulsive disorder patients (n = 955) using three measures: Yale-Brown Obsessive-Compulsive Scale severity ratings, the Dimensional Yale-Brown Obsessive-Compulsive Scale and the clinical global impression scale. We tested all factor structures reported by previous studies to investigate which model best fitted the data: one-factor, two-factor, three-factor and their equivalent high-order solutions. We also investigated Yale-Brown Obsessive-Compulsive Scale items correlations with scores from the other measures of obsessive-compulsive disorder severity. RESULTS: Confirmatory factor analysis models presented mediocre to fair goodness-of-fit indexes. Severity items related to resistance to obsessions and compulsions presented low factor loadings. The model with the best fit indexes was a high-order model without obsessive-compulsive disorder resistance items. These items also presented small correlations with other obsessive-compulsive disorder severity measures. CONCLUSION: The obsessive-compulsive disorder field needs to discuss further improvements in the Yale-Brown Obsessive-Compulsive Scale and/or continue to search for better measures of obsessive-compulsive disorder severity.

Long-term outcome of children and adolescents with obsessive-compulsive disorder: a 7-9-year follow-up of a randomized clinical trial.

Pediatric obsessive-compulsive disorder (OCD) is an impairing disorder frequently associated with long-term persistence. Long-term follow-up studies that investigated psychopathological trajectories after initial treatment are scarce. The present study is a 7-9-year follow-up of a randomized clinical trial (RCT) that tested the efficacy of group cognitive-behavioral therapy (CBT) and sertraline for children with OCD (n = 40), and aimed to describe long-term outcomes of pediatric OCD and identify predictors of these outcomes. Thirty-five participants who were included in the original study were recruited for follow-up evaluations. Participants underwent a comprehensive assessment of demographic and clinical characteristics comprised of the Structured Clinical Interview for DSM Disorders (SCID) and/or Kiddie-Schedule of Affective Disorders and Schizophrenia Present-Lifetime (K-SADS-PL), and the Yale-Brown Obsessive-Compulsive Scale (YBOCS). Thirty-three participants had a complete psychiatric assessment at follow-up (mean age 21 years, SD 3.2; 65% male). At follow-up, 13 (39.4%) participants had an OCD diagnosis, 10 (30.3%) had a diagnosis of any mental disorder (excluding OCD), and 10 (30.3%) did not have any diagnosis of mental disorder. In total, 23 participants (69.7%) had at least one mental disorder (including OCD). Among those without OCD (n = 20), 60.6% had a mental disorder. The following characteristics at follow-up were associated with OCD diagnosis: YBOCS total score (p < 0.001), global functioning (p = 0.008), and presence of any anxiety disorder (p = 0.027). Being treated with GCBT or sertraline during the original RCT did not predict OCD at follow-up. New treatment strategies should consider the role of psychopathological trajectories using a dynamic approach to combine or change interventions to enhance prognosis.

Systematic Review and Meta-analysis: An Empirical Approach to Defining Treatment Response and Remission in Pediatric Obsessive-Compulsive Disorder.

OBJECTIVE: A lack of universal definitions for response and remission in pediatric obsessive-compulsive disorder (OCD) has hampered the comparability of results across trials. To address this problem, we conducted an individual participant data diagnostic test accuracy meta-analysis to evaluate the discriminative ability of the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) in determining response and remission. We also aimed to generate empirically derived cutoffs on the CY-BOCS for these outcomes. METHOD: A systematic review of PubMed, PsycINFO, Embase and CENTRAL identified 5,401 references; 42 randomized controlled clinical trials were considered eligible, and 21 provided data for inclusion (N = 1,234). Scores of ≤2 in the Clinical Global Impressions Improvement and Severity scales were chosen to define response and remission, respectively. A 2-stage, random-effects meta-analysis model was established. The area under the curve (AUC) and the Youden Index were computed to indicate the discriminative ability of the CY-BOCS and to guide for the optimal cutoff, respectively. RESULTS: The CY-BOCS had sufficient discriminative ability to determine response (AUC = 0.89) and remission (AUC = 0.92). The optimal cutoff for response was a ≥35% reduction from baseline to posttreatment (sensitivity = 83.9, 95% CI = 83.7-84.1; specificity = 81.7, 95% CI = 81.5-81.9). The optimal cutoff for remission was a posttreatment raw score of ≤12 (sensitivity = 82.0, 95% CI = 81.8-82.2; specificity = 84.6, 95% CI = 84.4-84.8). CONCLUSION: Meta-analysis identified empirically optimal cutoffs on the CY-BOCS to determine response and remission in pediatric OCD randomized controlled clinical trials. Systematic adoption of standardized operational definitions for response and remission will improve comparability across trials for pediatric OCD.

Specialty knowledge and competency standards for pharmacotherapy for pediatric obsessive-compulsive disorder.

Evidence based treatments for pediatric Obsessive-Compulsive Disorder (OCD) are delivered with varying levels of expertise. This paper is part of the phase two series by the International OCD Accreditation Task Force (ATF) to advance a standardized high level of care globally. This paper presents specific knowledge and competencies recommended for specialized practice for pediatric psychopharmacologists working with OCD, developed by an international group of clinicians with extensive expertise in assessment and treatment of OCD. Tabulated knowledge and competency standards are operationalized as clinician abilities with specification of evidence for each standard. The distinction between current practice guidelines and ATF standards is discussed. Drug treatment has a solid evidence base. However, it should not be applied isolated, but informed by broad competence in general child and adolescent psychiatry and pediatrics. Other treatment relevant areas such as specialty CBT, family functioning, developmental issues, and neurobiology require consideration. Drug treatment includes several phases with varying degrees of evidence: Starting up medication, titration to maximum tolerated dose, maintenance, termination, and relapse prevention. In complex cases, pharmacotherapy with weak evidence may be needed to target symptoms and/or co-morbidity. The ATF knowledge and competency standards presented will be reviewed and updated commensurate with research.

[Cognitive-behavioral therapy in social phobia]. / Terapia cognitivo-comportamental da fobia social.

OBJECTIVE: This article reviews relevant aspects of social phobia and the stages of treatment within cognitive-behavioral therapy in children and adolescents, as well as in adults. METHOD: A review of the literature published on the treatment of social phobia using cognitive-behavioral treatments was performed using the Medline database. RESULTS: A review of the literature suggests that social phobia is a chronic and prevalent condition, characterized by social inhibition and excessive shyness. Diagnosis and treatment of the disorder are usually determined by distress level and functional impairment. Population studies indicate that lifetime prevalence rates for social phobia range from 2.5 to 13.3%. The main techniques used in cognitive-behavioral therapy for social phobia are described and exemplified in a case report. CONCLUSIONS: There is a general consensus in the literature that cognitive-behavioral therapy is efficacious in the treatment of youth and adults with social phobia. Because of the early onset associated with social phobia, the identification of children at high risk for the development of social phobia should be prioritized in future investigations.

Brief treatment for nighttime fears and co-sleeping problems: A randomized clinical trial.

Sixty-eight 4-6 year old children who co-slept with their parents and who avoided sleeping alone due to intense nighttime fears were randomized to a brief combined parent-based intervention (CBT-based bibliotherapy plus doll) or a wait list control group. After the waiting period, the wait list participants were offered treatment. Co-sleeping patterns, sleep records, anxiety, general fears, and behavior problems were assessed with parent-report measures. Nighttime fears were assessed with parent-report measures and a single item visual analogue scale for the young children. Assessments were completed pre-treatment, post-treatment, and at 3 months following treatment. Results showed that the combined intervention was superior to the wait list control condition and that treatment effects were maintained at 3-month follow-up. This study provides initial support for use of CBT-based bibliotherapy plus doll in the treatment of nighttime fears. Such a treatment might be used to supplement standard CBT approaches in routine clinical practice or in a stepped care approach to treatment.

Adaptive treatment strategies for children and adolescents with Obsessive-Compulsive Disorder: A sequential multiple assignment randomized trial.

OBJECTIVE: This sequential multiple assignment randomized trial (SMART) tested the effect of beginning treatment of childhood OCD with fluoxetine (FLX) or group cognitive-behavioral therapy (GCBT) accounting for treatment failures over time. METHODS: A two-stage, 28-week SMART was conducted with 83 children and adolescents with OCD. Participants were randomly allocated to GCBT or FLX for 14 weeks. Responders to the initial treatment remained in the same regimen for additional 14 weeks. Non-responders, defined by less than 50% reduction in baseline Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) scores, were re-randomized to either switch to or add the other treatment. Assessments were performed at baseline, 7, 14, 21, and 28 weeks. RESULTS: Among the 43 children randomized to FLX who completed the first stage, 15 (41.7%) responded to treatment and 21 non-responders were randomized to switch to (N = 9) or add GCBT (N = 12). Among the 40 children randomized to GCBT who completed the first stage, 18 (51.4%) responded to treatment and 17 non-responders were randomized to switch to (N = 9) or add FLX (N = 8). Primary analysis showed that significant improvement occurred in children initially treated with either FLX or GCBT. Each time point was statistically significant, showing a linear trend of symptom reduction. Effect sizes were large within (0.76-0.78) and small between (-0.05) groups. CONCLUSIONS: Fluoxetine and GCBT are similarly effective initial treatments for childhood OCD considering treatment failures over time. Consequently, provision of treatment for childhood OCD could be tailored according to the availability of local resources.

Obsessive-compulsive symptoms among patients with Sydenham chorea.

BACKGROUND: Among patients with tic disorders, a distinctive clinical profile of obsessive-compulsive symptomatology has been described. The present investigation was designed to document the phenomenology of obsessive-compulsive symptoms (OCS) among patients with Sydenham chorea (SC), the neurologic variant of rheumatic fever. We hypothesized that OCS occurring in association with SC would be similar to those among patients with tic disorders. METHODS: The authors studied the presence of OCS in 73 patients with SC by using the Yale-Brown Obsessive-Compulsive Scale at the Pediatric Clinics of the University of Sao Paulo Medical Center in Sao Paulo, Brazil (n = 45) and at the National Institute of Mental Health in Bethesda, Maryland (n = 28). RESULTS: The most frequent symptoms observed among subjects with comorbid SC and OCS were aggressive, contamination, and somatic obsessions and checking, cleaning, and repeating compulsions. A principal component factor analysis yielded a five-factor solution (accounting for 64.5% of the total variance), with contamination and symmetry obsessions and cleaning compulsions loading highly. CONCLUSIONS: The symptoms observed among the SC patients were different from those reported by patients with tic disorders but were similar to those previously noted among samples of pediatric patients with primary obsessive-compulsive disorder.

[Anxiety disorders in childhood and adolescence: clinical and neurobiological aspects]. / Transtornos ansiosos na infância e adolescência: aspectos clínicos e neurobiológicos.

OBJECTIVE: This article reviews the clinical and epidemiological aspects of anxiety disorders in youngsters, as well as current medical and psychological treatment strategies. The role of the neurobiological models possibly involved in the etiology of these disorders is also discussed. SOURCES OF DATA: MEDLINE search of papers published in English from 1981 to 2003. The following key words were used: anxiety disorders, neurobiology, childhood, adolescence. SUMMARY OF THE FINDINGS: Childhood-onset anxiety disorders are among the most frequent psychiatric conditions in children and adolescents. Epidemiological data estimate a prevalence of 10% in this population. The neurobiological models involved in the etiology of anxiety disorders in youngsters are closely related to neuroimaging studies with individuals presenting these pathologies. The role of the amygdala in the pathophysiology of these disorders is underscored. To be effective, treatment must combine several interventions, such as cognitive-behavioral, family, and, frequently, drug treatments. CONCLUSIONS: Early identification and prompt treatment of anxiety disorders may prevent negative consequences, such as school absenteeism and frequent and unnecessary visits to pediatric services due to somatic complaints related to anxiety disorders. Moreover, it is possible that psychiatric problems could be avoided or attenuated in adulthood.

Terapia cognitivo-comportamental da fobia social / Cognitive-behavioral therapy in social phobia

OBJETIVO: Este artigo revisa aspectos relevantes da fobia social e os estágios de tratamento através da terapia cognitivo-comportamental em crianças, adolescentes e adultos. MÉTODO: A partir do banco de dados Medline, realizou-se revisão da literatura publicada a respeito do tratamento da fobia social por meio da terapia cognitivo-comportamental. RESULTADOS: Revisão da literatura sugere que a fobia social é uma condição prevalente e crônica, caracterizada por inibição social e timidez excessiva. Tanto o diagnóstico como o tratamento desse transtorno são comumente determinados pelo nível de incômodo e pelo prejuízo funcional. Estudos populacionais indicam taxas de prevalência ao longo da vida para a fobia social entre 2,5 e 13,3 por cento. As principais técnicas utilizadas na terapia cognitivo-comportamental para a fobia social são descritas e exemplificadas em um relato de caso. CONCLUSÕES: Há consenso geral na literatura de que a terapia cognitivo-comportamental é eficaz tanto para o tratamento de jovens como de adultos com fobia social. Uma vez que a fobia social com freqüência tem início precoce, a identificação de crianças com risco acentuado para o desenvolvimento de fobia social deve ser priorizada em investigações futuras.

Transtornos ansiosos na infância e adolescência: aspectos clínicos e neurobiológicos / Anxiety disorders in childhood and adolescence: clinical and neurobiological aspects

OBJETIVO: Este artigo revê as características clínicas e epidemiológicas dos diversos transtornos ansiosos em jovens, bem como as estratégias atuais utilizadas nos tratamentos medicamentosos e psicológicos. Enfatiza-se, além disso, o papel de modelos neurobiológicos possivelmente relacionados à etiologia desses quadros. FONTES DOS DADOS: A partir de pesquisa em banco de dados no MEDLINE, foram selecionados artigos publicados em inglês entre 1981 e 2003. Para tal fim, foram utilizados os seguintes termos: "anxiety disorders", "neurobiology", "childhood" e "adolescence". SíNTESE DOS DADOS: Os transtornos ansiosos encontram-se entre as condições psiquiátricas mais comuns na população pediátrica. Estima-se que até 10 por cento desta população possa apresentar algum quadro patológico de ansiedade durante a infância ou adolescência. Os modelos neurobiológicos relacionados à etiologia dos transtornos ansiosos em jovens estão intimamente relacionados aos estudos de neuroimagem com portadores desses quadros. Destaca-se o papel da amígdala na fisiopatologia desses transtornos. O tratamento eficaz requer a combinação de várias intervenções, como a cognitivo-comportamental, a familiar e, freqüentemente, a medicamentosa. CONCLUSÕES: A identificação e o tratamento precoces dos transtornos de ansiedade podem evitar repercussões negativas na vida da criança, tais como faltas constantes à escola e a conseqüente evasão escolar, a utilização demasiada de serviços de pediatria por queixas somáticas associadas à ansiedade e, possivelmente, a ocorrência de problemas psiquiátricos na vida adulta. Avanços em estudos neurobiológicos, em especial no entendimento das funções da amígdala em indivíduos normais, facilitarão tanto o esclarecimento dos mecanismos fisiopatológicos envolvidos nos transtornos ansiosos como seu tratamento.
