We conducted descriptive and experimental analyses of aberrant behavior in school settings with 2 children with autism, using teachers as assessors. Experimental functional analyses carried out by the investigators were followed by training teachers to conduct a descriptive analysis and a classroom experimental analysis. A comparison of the assessment procedures showed that each procedure identified negative reinforcement as a maintaining variable for aberrant behavior. The teacher implemented an intervention based on the assessment with mixed results. We then replicated the initial results by having the first teacher train a second teacher to carry out the two assessment procedures. The results of these analyses were also in agreement, again identifying negative reinforcement as a variable maintaining aberrant behavior. An intervention based on negative reinforcement was then successfully implemented. These results suggest the applicability and utility of functional analyses carried out in school settings.
