The Children's Yale-Brown Obsessive Compulsive Scale: Reliability and Validity for Use Among 5 to 8 Year Olds with Obsessive-Compulsive Disorder.
Summary of "The Children's Yale-Brown Obsessive Compulsive Scale: Reliability and Validity for Use Among 5 to 8 Year Olds with Obsessive-Compulsive Disorder."
The Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) is the instrument of choice for assessing symptom severity in older children (i.e., 8-18 years) diagnosed with obsessive-compulsive disorder (OCD). The reliability and validity of this measure for use among younger children (i.e., 5-8 years of age), however, has never been examined. The primary aim of this study was to examine this scale's use among those presenting with early childhood OCD. Forty-two children with OCD between the ages of 4 and 8 years of age were recruited as part of a larger treatment outcome study, and the reliability and validity of the CY-BOCS was examined. Results revealed questionable reliability for the measure's 5-item Obsessions subscale but good reliability (i.e., internal consistency, temporal stability) for the 5-item Compulsions subscale and 10-item total scale. Results also revealed that the CY-BOCS total scale demonstrated mixed discriminant validity but strong convergent validity and sensitive to change. Collectively, the 10-item, CY-BOCS total score yields a reliable and valid scale for the assessment of symptom severity in early childhood OCD. However, we urge caution in use of the Obsessions subscale in isolation for either clinical or research purposes. Limitations and future areas of research are discussed including the potential benefit of developing a measure of OCD-related symptom severity specifically for younger children with greater attention to developmental differences among children within this population.

Medical and Biotech [MESH] Definitions
Obsessive-compulsive Disorder
An anxiety disorder characterized by recurrent, persistent obsessions or compulsions. Obsessions are the intrusive ideas, thoughts, or images that are experienced as senseless or repugnant. Compulsions are repetitive and seemingly purposeful behavior which the individual generally recognizes as senseless and from which the individual does not derive pleasure although it may provide a release from tension.
Brief Psychiatric Rating Scale
A scale comprising 18 symptom constructs chosen to represent relatively independent dimensions of manifest psychopathology. The initial intended use was to provide more efficient assessment of treatment response in clinical psychopharmacology research; however, the scale was readily adapted to other uses. (From Hersen, M. and Bellack, A.S., Dictionary of Behavioral Assessment Techniques, p. 87)
Adipose Tissue, Brown
A thermogenic form of adipose tissue composed of BROWN ADIPOCYTES. It is found in newborns of many species including humans, and in hibernating mammals. Brown fat is richly vascularized, innervated, and densely packed with MITOCHONDRIA which can generate heat directly from the stored lipids.
Language Tests
Tests designed to assess language behavior and abilities. They include tests of vocabulary, comprehension, grammar and functional use of language, e.g., Development Sentence Scoring, Receptive-Expressive Emergent Language Scale, Parsons Language Sample, Utah Test of Language Development, Michigan Language Inventory and Verbal Language Development Scale, Illinois Test of Psycholinguistic Abilities, Northwestern Syntax Screening Test, Peabody Picture Vocabulary Test, Ammons Full-Range Picture Vocabulary Test, and Assessment of Children's Language Comprehension.
Glasgow Outcome Scale
A scale that assesses the outcome of serious craniocerebral injuries, based on the level of regained social functioning.
