Randomized trial in a preschool for children with developmental delays (16 intervention, 16 comparison children) measuring frequencies of appropriate and inappropriate behaviors during semi-structured play; the report notes "insufficient information for the WWC to calculate effect sizes or to verify the significance tests".

"LeBlanc and Matson (1995) analyzed two outcomes in this domain and found a statistically significant positive effect favoring the intervention on one outcome but no significant difference between the groups on the other outcome."
