Funct. Assess. of Beh Disturbances: Diagnostic Features ASD

FUNCTIONAL ASSESSMENT OF BEHAVIORAL DISTURBANCES: DIAGNOSTIC FEATURES OF ASD BEHP1041 - Addresses functional assessment methodologies for severe behavior problems in persons with disabilities. Covers comparing outcomes of functional assessment experiments involving persons with and without ASD, studying where core diagnostic features of ASD were the focus of investigation, examining how core diagnostic features of ASD can interact with aspects of the environment to give rise to severe problem behavior, and other less-considered ways in which these interactions may occur.

Reinforcement-Based Interventions for Problem Behavior in IDD

REINFORCEMENT-BASED INTERVENTIONS FOR PROBLEM BEHAVIOR IN IDD - BEHP1092 Involves standard of care for severe behavior problems of persons with intellectual and developmental disabilities including conducting assessments to determine the variables that give rise to and support problem behavior and hypothesis-driven interventions that address these causes. Includes typical interventions such as disrupting the contingency between problem behavior and the consequences that support it (i.e., extinction), and establishing or strengthening alternative behavioral repertoires to displace problem behavior.
