The aim of this study was to explore the incidence, type and severity of motor impairment in male adolescents with a disruptive behavior disorder (DBD) and evaluate the role of comorbid ADHD. The Bruininks-Oseretsky test of motor proficiency, Second Edition was administered to examine a detailed motor profile and to compare the motor abilities of individuals with DBD (n = 99) to those of controls (n = 87). Additional subgroup analyses were conducted within the clinical population and encompassed (1) analyzing differences in motor profiles between individuals diagnosed with oppositional defiant disorder (ODD) or conduct disorder (CD) and (2) comparing the motor profiles of individuals with or without comorbid ADHD. The results indicated that individuals with a DBD showed a mixed motor impairment profile. Even after controlling for IQ, the DBD group obtained significantly lower scores in comparison to controls. The ODD and CD subgroups showed a similar motor profile. Presence of comorbid ADHD did not produce major differences in the motor profile. As approximately 79% of the adolescents with a DBD suffered from motor impairment, motor ability needs to be adequately addressed in research as well as in clinical practice. (C) 2015 Elsevier Ltd.
