Situational variation in problem behavior at home and school in attention deficit disorder with hyperactivity: a factor analytic study.

The present investigation assesses situational variation in problem behaviors of children with Attention Deficit Disorder with Hyperactivity. Principal-component factors (VARIMAX rotation) were computed for the Home/School Situations Questionnaires (HSQ/SSQ). For the HSQ, four factors emerged, accounting for 61% of variance. For the SSQ, three factors emerged, accounting for 68% of variance. Factors were similar to those previously derived with non-referred children. To assess discriminative power, factors were compared (t-tests) to previous data. All factors significantly discriminated ADD/H from non-referred children. These data suggest the factors add to the utility of the HSQ/SSQ in assessing ADD/H.
