This dissertation is an exploration of the experiences and perceptions the behavior support plan (BSP) had on individuals placed into residential services or an independent living facility through a state waiver in Indianapolis, Indiana. Autistic high school graduates were addressed in this study to look at the various behaviors they faced when transitioning into an independent or residential living facility. Individuals with a diagnosis of autism spectrum disorder will be facing this issue if they are not placed into homes and if it is not addressed, there will be confusion on where to place these individuals after graduation. The purpose of this qualitative phenomenology is to gain an understanding of the transitional experiences of autistic high school graduates who completed a BSP. Two theories were used in the framework for this study: (a) operant behavior, and (b) social cognitive theory. Ten participants with autism who completed high school each took part in a 90-minute phone interview. Interviews were digitally recorded, transcribed, and analyzed by using a constant comparative method associated with a grounded theory approach. The findings were based on the following research questions: (1) What behavioral changes do participants perceive after transitioning into an independent living or residential facility?; (2) What behavioral changes in aggression have participants perceived?; (3) What behavioral changes have participants noticed in relation to daily skills?; and (4) How has the BSP influenced participants' behaviors? The present study supported literature that states that transitions impact behaviors. Results showed support from staff and the environment all affected behavioral changes when transitioning. Results also showed participants experienced more aggression when there was no structure provided to them within their environment. Some recommendations for future research that would provide further information in helping to structure the BSP for behavior consultants include behavioral changes when staff is trained vs. not being trained and studying the individual's past environments and the support they were provided. A final recommendation would be a study investigating the time the BSP was written and changes in behaviors before and after transitioning into an independent or residential facility.
