“…In non-clinical samples (e.g., Stanger & Lewis, 1993;Thomas, Forehand, Armistead, Weirson, & Frauber, 1990;Verhulst & van der Ende, 1992) and clinical samples of various presenting problems (e.g., Kazdin, French, & Unis, 1983;Mokros, Poznanski, Grossman, & Freeman, 1987;Thurber & Osborn, 1992;Thurber & Snow, 1990) parent and child reports are consistently found to deviate one from another. In fact, meta-analytic research has found that on the average parent and child reports correlate at approximately .30 (Achenbach, McConaughty, & Howell, 1987).…”
