"The Oregon Intervention System (OIS) is Oregon"s system of training and implementing the principles of Positive Behavior Intervention and Support (PBIS) and Interventions to staff that support adults and children with Intellectual/Developmental Disabilities (I/DD) that may display challenging behaviors.OIS and all materials produced by OIS are the property of the Oregon Department of Human Services Office of Developmental Disability Services (DHS-ODDS). Written permission is required for reproduction. Unauthorized reproduction of any materials produced by OIS is subject to legal recourse.OIS also embraces the principles of PBIS, which was developed and researched at the University of Oregon and other institutions of higher learning. PBIS emphasizes fully assessing a behavior to identify the function(s) the behavior serves for the individual, and then developing supports, which will eventually render the behavior inefficient, ineffective, and irrelevant. These supports include making changes to the environment, which will reduce stress and uncertainty for the individual; teaching the individual more efficient and effective skills; and changing the way staff respond to the individual and the challenging behavior. PBIS focuses on a proactive (preventative) approach, reinforcing desired behaviors, without the use of punishment, intimidation, or any aversive intervention.The OIS curriculum is revised when necessary to reflect Evidenced Based Practices within the field of I/DD, integrating new research related to human behavior and support. The current OIS curriculum represents the most advanced integration of the principles of PBIS, Person-Centered Practices, Self-Determination, and community participation to date. The core principles in the OIS curriculum continue to emphasize proactive and preventative measures, which enhance an individual"s life; adherence to sound and proven Positive Behavioral Theory and practices; and as a last resort, the use of safe and effective safety interventions involving Physical Skills Techniques, which may include Protective Physical Interventions (PPIs) while maintaining the individual"s dignity."
