In addition, 80 % of pervasive children whose mothers were highly critical immediately posttreatment were classified as
school nonresponders at the 2 - year follow - up.
However, there was no evidence of selective attrition according to whether the family had received the intervention; the percentages of
nonresponders in the intervention and control groups were similar for mothers who were < 20 years of age, who had less than high
school education, and who were black, Hispanic, and not married (data available on request).
