The current study evaluated three subjects with developmental disabilities, using a Mindfulness activity protocol to promote psychological flexibility, as well as exercising this developed flexibility to reduce problem behaviors. The success of the Mindfulness procedure was evaluated using a multiple baseline across participants design. Results of this study presented that after partaking in Mindfulness activities, all participants displayed decreases in problematic behavior, as well as increased scores on the Children’s Psychological Flexibility Questionnaire (CPFQ). Overall, there was a general trend of reduced problematic behavior from baseline to post-intervention. Participants’ behavioral frequency rates were reduxed an overall average of 25.2%. In addition to general maladaptive behavior reductions, participants’ CPFQ scores were improved across participants by an overall average improvement of 11.8%.
