The present research reports use of an intervention package centering on self-recording with a boy with pervasive developmental disorder (PDD) who had aggressive and disruptive behavior and used violent language. The intervention had the following components: (a) the participant recorded occurrences of his own challenging behavior, (b) others reinforced occurrences of his adaptive behavior, and the child himself recorded the number of reinforcers received, and (c) a token economy system with response cost was used, in which the child's scores were computed from the contents of the records he had kept and the resulting scores could be exchanged for backup reinforcers. The inappropriate target behavior disappeared after the start of the intervention, showing repeated increases and decreases. The child recorded fewer target behaviors than his mother did. The number of recorded reinforcers for adaptive behavior received from others was maintained. The recording method and backup reinforcers appeared to influence maintenance of the behavior of self-recording. Moreover, there is a possibility that the child's recording the number of reinforcers received from others for occurrence of adaptive behavior may have affected the occurrence of the target behavior.
