title: Testing Multiple Conceptualizations of Oppositional Defiant Disorder in Youth.
abstract: Recent theories conceptualize oppositional defiant disorder (ODD) as a two-dimensional construct with angry/irritable (i.e., affective) and argumentative/defiant (i.e., behavioral) components. This view has been supported by studies of nonreferred youth but not yet examined in clinic-referred youth. In a reanalysis of data regarding children who received one of two psychosocial ODD treatments, we examined multiple conceptualizations of ODD, whether children showed improvements across these ODD dimensions, and whether main and joint effects of ODD dimension improvement predicted clinical outcome. One hundred thirty-four clinic-referred youth (ages 7-14 years, 38% female, 84% White) who met Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for ODD received 1 of 2 psychosocial treatments. At pretreatment, 1-week follow-up, and 6-month follow-up, mothers reported child aggression and conduct problems, clinicians reported global clinical impairment and clinical improvement, and ODD symptom counts were collected from a semistructured diagnostic interview with mothers. Baseline ODD symptom were used to test previously supported multidimensional models. One- and two-factor conceptualizations were supported; however, the two-factor solution was preferred. With this solution, each dimension significantly and similarly improved across treatment conditions. Improvements across affective and behavioral ODD factors also had significant effects on clinician- and mother-reported clinical outcomes. The current findings provide empirical support for the ongoing study of multidimensional ODD conceptualizations in clinic-referred youth.
