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.

Purpose of this study is to adapt anxiety and depression questionnaire for children into Turkish culture and to analyze the psychometric characteristics of it on clinical and nonclinical samples separately. The study is a descriptive survey research. The study was conducted on two different sample groups, clinical and nonclinical. The clinical sample is formed of 205 individuals and the nonclinical sample is formed of 630 individuals. Through the study, anxiety and depression questionnaire for children, anxiety sensitivity index and obsessive compulsive disorder questionnaire for children were used. Experts’ opinions were asked to provide language validity of the scale. Confirmatory factor analysis and criterion-related validity to analyze construct validity and internal consistency and split-half reliability analyses were done for reliability. In the direction of experts’ opinions, construct validity of the scale was analyzed with simple confirmatory factor analysis and it was determined that the model fit of the two-factor structure of the scale gives good fit on both the clinical and nonclinical samples after determining that the language validity of the scale is provided. In criterion-related validity, it was determined that there are positive and significant relations between anxiety and depression questionnaire for children and anxiety sensitivity and obsessive compulsive disorder. The results of internal consistency and half-split reliability analyses also show that the scale has adequate reliability value.

Inflated Responsibility

Introduction: Inflated responsibility has been hypothesized as an important influence on OCD symptoms. According to Salkovskis and colleagues (1999) there are in turn five developmental pathways that lead to inflated responsibility. Coles and Schofield (2008) proposed the Pathways to Responsibility Beliefs Scale (PIRBS) as a measure of these pathways. Method: In the present study the psychometric properties of an Icelandic translation of the PIRBS were evaluated and its factor structure was studied in a confirmatory factor analysis. Further it was tested whether responsibility mediated between pathways to responsibility beliefs and OCD symptoms. Results: While neither a four nor a five-factor structure of the PIRBS was found to be wholly satisfactory; support for the latter was slightly better. Correlations of the PIRBS scales with measures of responsibility and obsessive-compulsive disorder symptoms were moderate as expected. Support was found for a mediating role of responsibility attitudes between pathways measured by the PIRBS and OCD symptoms in support of Salkovskis and colleagues' theory (1999). Conclusion: The PIRBS is a promising approach to study the developmental precursors of inflated responsibility and OCD symptoms but its factor structure may need a revision

Objective: Measuring, diagnosing, and determining the severity of the symptoms of Obsessive-Compulsive Disorder (OCD) is essential for studying mental health issues. This study aimed to determine the psychometric properties of the Persian version of the Dimensional Obsessive-Compulsive Scale (DOCS) in a non-clinical population. Methods: In this cross-sectional study, 252 residents of Tehran (Iran) were selected by cluster sampling method from different districts. They were asked to complete DOCS, Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), and Obsessive-Compulsive Inventory-Revised (OCI-R). SPSS v. 21 and LISREL statistical software were used for data analysis. Cronbach's alpha, exploratory and confirmatory factor analysis, Spearman correlation were also used. Results: The Internal consistency of DOCS was 0.916 based on the Cronbach α value. The correlations of DOCS with Y-BOCS and OCI-R were 0.57 and 0.55, respectively. Exploratory factor analysis showed four factors. Confirmatory factor analysis also showed that this four-factor and higher-order factor models had a good fit for the data. Conclusion: The present study indicated acceptable validity and reliability of DOCS in non-clinical populations in Iran. Therefore, this scale be used to screen people with OCD symptoms in non-clinical centers of mental health assessment.

Pupil with Obsessive-Compulsive Disorder. Over the past twenty years childhood OCD has received more attention than any other anxiety disorder that occurs in the childhood. The increasing interest and research in this area have led to increasing number of diagnoses of OCD in children and adolescents, which affects both specialists and teachers. Depending on the severity of symptoms OCD has a detrimental effect upon child's school performance, which can lead almost to the impossibility to concentrate on school and associated duties. This article is devoted to the obsessive-compulsive disorder and its specifics in children, focusing on the impact of this disorder on behaviour, experience and performance of the child in the school environment. It mentions how important is the role of the teacher in whose class the pupil with this diagnosis is and it points out that it is necessary to increase teachers' competence to identify children with OCD symptoms, to take the disease into the account, to adapt the course of teaching and to introduce such measures that could help children reduce the anxiety and maintain (or increase) the school performance within and in accordance with the school regulations and curriculum.

The Fourth International Obsessive Compulsive Disorder Conference (IOCDC) was held February 10–12, 2000, on the beautiful island of St. Thomas. The IOCDC is an annual meeting which brings together the world's leading experts in obsessive-compulsive disorder (OCD) and related disorders in a small workshop setting to present recent research advances, discuss gaps in our current knowledge, and plan or international approaches that address these knowledge gaps. The IOCDC meetings have been held on islands on both sides of the Atlantic—Capri, Guadeloupe, Madeira, and now St. Thomas.The International Organizing Committee consists of Eric Hollander, MD (USA), Joseph Zohar, MD (Israel), and Donatella Marazziti, MD (Italy). The proceedings are generously supported by an unrestricted educational grant from Solvay Pharmaceuticals Inc. and Solvay Pharmaceuticals, and we would like to acknowledge the very important contributions of Chantal Vekens and Mary Blangiardo of Solvay. Also, an mportant part of the success of these meetings stems from the very active role of the chairpersons and cochairpersons of the workshops who lead the discussions, who synthesize the future directions and prepare the manuscripts that result from these discussions that appear in this academic supplement.The meeting led off with a state-of-the-art plenary address by Mark George, MD (USA), describing how new methods of brain stimulation are improving research and therapy in OCD and promise to revolutionize neuropsychiatric research and herapy over the next decade. He describes how transcranial magnetic stimulation (TMS) is used to test the circuits in OCD and test electrophysiologic evaluations of cortical inhibition n OCD. Newer techniques that are less invasive than ablative surgery and appear promising in OCD therapy include vagus nerve stimulation and deep brain stimulation.
