The effectiveness of a mass screening procedure was examined within the context of a preventively oriented school-based treatment program. Mass screening consisted primarily of teachers rating the frequency of all primary grade children's acting-out, moody-withdrawn, and learning problem behaviors. While teachers directly referred 6.9% (n = 48) of the primary grade population of three inner-city schools (n = 698), mass screening subsequently identified an additional 9.7% (n = 68) of this population. Furthermore, both referred and screened-in groups were rated by teachers on the Child Activity Rating Scale (CARS) as behaving much less adaptively relative to a normative group (n = 285; ps < .001). As expected, the referred children evidenced greatest overall dysfunctioning with most pronounced acting-out and learning problems according to ratings by teachers. In addition, further evidence of the validity of the CARS rating form was demonstrated by the agreement between staff predictions of CARS scores and actual ratings by teachers. The mass screening procedure employed is discussed as an effective procedure and suggestions are offered which could increase its utility.
