Sub-categorizing hyperactivity: a replication and extension of the stony brook scale

Abstract

The Stony Brook Scale (SBS) is a behaviour rating scale which is clamed to have the ability to sub-categorize highly selected groups of hyperactive children <0’U*ry * Steen, 1982). in particular, it has been suggested that this scale can differentiate between purely hyperactive and aggressive children. B * present study sought to replicate the research of 0' Leary and Steen (1982) and to extend the application of the Stony Brook Scale to parent ratings of child behaviour. Fom-erly, only teache ntings on the scale had been examined. •Three separate factor analyses were conducted on the following (a) ^acher ratings on the SBS for a specifically selected garble of hyperactive children (n » 90); (b) parent ratings on the SBS for the same specifically selected sample of hyperactive children (n * 86)j (C) %adier SBS ratings for a heterogeneous sample of * schoolchildren (n * 90),
