The limited amount of literature available suggests the utility of psychotherapy for people with developmental disabilities. The present study assessed the effects of an individual psychotherapy program with 10 children and teens, as measured by the Developmental Behavior Checklist and the Nisonger Child Behavior Rating Form (Parent Version). Results, using parent report, indicated that there was overall improvement from the beginning of the program to the six month point. Two suggestions are provided for evaluation improvement: 1) because the measures did not always capture the concerns of the clients, the General Change Questionnaires were developed to supplement data gathered; and 2) because the perspective of the client is missing from the evaluation, the Dominic Interactive is being pilot tested.
