Validation of three dimensions of childhood psychopathology in young clinic-referred boys

Short measures of child inattention-overactivity (IO), aggression-defiance (AG), and anxiety-depression or emotionality (EM) derived through a double validation procedure are administered to mothers of 243 clinic-referred suburban New York boys between 6 and 10 years of age. Mother-rated IO is uniquely related to poor performance on cognitive and achievement tests; observed inattentive, hyperactive, and impulsive behaviors in a restricted academic setting; less father education and lower family income; and most mother-reported impairments and treatment use. Mothers of high-IO boys describe themselves and their sons as having similar childhood symptoms. AG is uniquely related to child-reported disruptive behavior and sensation seeking, many measures of family conflict and negative parenting styles, and mother-reported symptom pervasiveness and number of treatments. EM is uniquely related only to poorer cognitive and achievement test performance, living with one parent, parents who considered themselves too busy, and fewer friends. Each dimension also is associated with parallel teacher-rated factors.
