Positive reinforcement is effective when used as an intervention for children with inappropriate behaviors. Children with the diagnosis of Schizoid Personality Disorder (SP) and/or Attention Deficit Hyperactivity Disorder (ADHD) may exhibit inappropriate behaviors that inhibit their quality of life.

The data that was collected was analyzed by a two-way ANOVA test. Several types of reinforcement interventions were researched and discussed
