RT Journal Article T1 Operational definitions and measurement of externalizing behavior problems: An integrative review including research models and clinical diagnostic systems A1 Torres Rosado, Lidia A1 Lozano Rojas, Óscar Martín A1 Sánchez García, Manuel A1 Fernández Calderón, Fermín A1 Díaz Batanero, María Carmen AB Measurement of externalizing disorders such as antisocial disorders, attention-deficit/hyperactivity disorder or borderline disorder have relevant implicationsfor the daily lives of people with these disorders. While the Diagnostic andStatistical Manual of Mental Disorders (DSM) and the International Classificationof Diseases (ICD) have provided the diagnostic framework for decades, recentdimensional frameworks question the categorical approach of psychopathology,inherent in traditional nosotaxies. Tests and instruments develop under the DSMor ICD framework preferentially adopt this categorical approach, providingdiagnostic labels. In contrast, dimensional measurement instruments provide anindividualized profile for the domains that comprise the externalizing spectrum,but are less widely used in practice. Current paper aims to review the operationaldefinitions of externalizing disorders defined under these different frameworks,revise the different measurement alternatives existing, and provide an integrativeoperational definition. First, an analysis of the operational definition of extern-alizing disorders among the DSM/ICD diagnostic systems and the recentHierarchical Taxonomy of Psychopathology (HiTOP) model is carried out. Then,in order to analyze the coverage of operational definitions found, a description ofmeasurement instruments among each conceptualization is provided. Threephases in the development of the ICD and DSM diagnosis systems can beobserved with direct implications for measurement. ICD and DSM versions haveprogressively introduced systematicity, providing more detailed descriptions ofdiagnostic criteria and categories that ease the measurement instrument development. However, it is questioned whether the DSM/ICD systems adequately modelizeexternalizing disorders, and therefore their measurement. More recent theoretical approaches,such as the HiTOP model seek to overcome some of the criticism raised towards the classificationsystems. Nevertheless, several issues concerning this model raise mesasurement challenges. Arevision of the instruments underneath each approach shows incomplete coverage of externalizingdisorders among the existing instruments. Efforts to bring nosotaxies together with othertheoretical models of psychopathology and personality are still needed. The integrativeoperational definition of externalizing disorders provided may help to gather clinical practice andresearch.
