Document Summary
Classification (a system for describing important categories, groups, or dimensions of a disorder) Diagnosis (the method of assigning an individual to a specific classification category: first step in deciding the course of treatment. Reliability: a measure of consistency, measures whether different clinicians classify individuals into the same categories. Validity: whether the classification gives us true to life, meaningful information. Externalizing & internalizing: externalizing dimension: under controlled behaviours, such as oppositional or aggressive beh. Internalizing dimension: over controlled behaviours, such as anxiety or social isolation. Dsm5 v codes: conditions of significant factors that aren"t disorders, but can have strong influence of treatment. Issues in classification of abnormal behavior: categorical classification: Entities of objects being classified must be ranked on a quantitative dimension. Identifies key dimensions of function and dysfunction. Assumes that all individuals can be meaningfully described along these dimensions. Emphasizes differences in degree (or quantity) of a dimension, rather than differences in kinds (quality) of dimensions.
