title: A two-year follow-up study of a preventive mental health program for preschoolers.
abstract: The long-term effects of a preschool intervention program for high-risk experimental children were assessed and compared to a high-risk placebo control group and low-risk "normal" controls. Seventy first-grade children were involved in this 2-year follow-up. The experimental treatment group was superior to that of the placebo control group at follow-up on the criteria measures of behavioral adjustment and achievement. The low-risk "normal" control group was significantly different from that of the placebo control groups, but generally not significantly different from that of the experimental groups, suggesting that the intervention had boosted the high-risk experimental treatment children to the point where their performance was comparable to that of children who had not experienced behavioral or learning difficulties.
