Empirical research revealed that positive behavior support technique can promote meaningful lifestyle changes across a wide spectrum of persons with disabilities and settings. The purpose of this study was to evaluate the effectiveness of a family-centered positive behavior support approach in the treatment of extreme food refusal behavior in a child with autism spectrum disorders. This single subject study used multiple measurement procedures to monitor the dependent variables and to document implementation of independent variable (i.e., intervention procedure). The researcher served as the primary interventionist throughout the study and collaborated with the family on intervention development and implementation activities. The dinner routine was selected for assessment and intervention. Four dependent variables were measured, and observation data were gathered across baseline, intervention, maintenance, and follow-up phases. The results showed improvement in aberrant behaviors, the increase of acceptance of bite consumption, and successful participation in targeted meal routine from baseline to intervention phases. Further evidence of efficacy of this support approach was found in the modest improvement in social validity, family quality of life, and parental stress. The findings of this investigation indicated that the ecological behavior intervention provided through parent-professional collaboration was acceptable and affective. Moreover, family-professional collaboration provides appropriate frameworks for planning, designing, and implementing positive behavioral support intervention, and for documenting its impact, specifically in the context of early intervention. |
