Murray, Aja Louise Eisner, Manuel Ribeaud, Denis <jats:p> Abstract. The shift toward transdiagnostic and dimensional approaches to psychopathology research has created a growing need for psychometric assessments that reflect this conceptualization. We aimed to test whether an omnibus measure of psychopathology, the Social Behavior Questionnaire (SBQ), has suitable properties to serve as a dimensional, transdiagnostic assessment. We used an item response theory (IRT) approach to evaluate the reliable ranges of measurement of the psychopathology dimensions measured by the SBQ. For the dimensions of attention-deficit hyperactivity disorder (ADHD), Prosociality, Internalizing, and Externalizing, the SBQ can provide a reliable measure for below average to very high levels in a normative sample. </jats:p> application/pdf https://sonar.ch/global/documents/235824 eng info:eu-repo/semantics/altIdentifier/doi/10.1027/1015-5759/a000442 info:eu-repo/semantics/altIdentifier/issn/1015-5759 info:eu-repo/semantics/openAccess European Journal of Psychological Assessment. - Hogrefe Publishing Group. - 2019, vol. 35, no. 5, p. 674-679 Applied Psychology Can the Social Behavior Questionnaire Help Meet the Need for Dimensional, Transdiagnostic Measures of Childhood and Adolescent Psychopathology? http://purl.org/coar/resource_type/c_6501
