A Single Subject Evaluation of the K-P Diet for Hyperkinesis

Abstract

A single subject ABAB design was employed to determine the effectiveness of the Feingold Kaiser Permanente (K-P) diet in the treatment of a 6-year-old hyperkinetic male hypothesized to be diet-responsive. Secondary aims were to assess both the nutritional adequacy of the diet and the problems involved in implementing it. Diet effectiveness was measured by classroom observations ofattending-to-task, out-ofseat, and movement behaviors; and by teacher and foster-mother reports. It was concluded that the K-P diet was effective in controlling the subject's hyperkinesis. The diet was also shown to be nutritionally adequate and moderately difficult to implement.
