Project "TEAM" teaches transition-age youth with developmental disabilities (DD) to identify physical and social environmental barriers and supports, generate solutions to barriers, and request modifications to increase participation. Establishing the social validity of this environment focused intervention with youth and their parents…

Functional Behavior Assessment (FBA) and behavior interventions have been effective in the management of challenging behavior among children with developmental disabilities including autism spectrum disorders. Research suggests the need for valid measurement instruments for verifying, calibrating and scoring competence in FBA and behavior…

The number of postsecondary education (PSE) programs for individuals with intellectual and developmental disabilities (IDD) has been steadily growing over the last few decades. There has been little public information regarding these programs and schools. Consequently, students, families, and researchers alike lack details about the various…

The objective of present research is to conduct validity and reliability analysis of the verbal section of Test of Pretended Play that will measure pretended play behaviors of pre-school age children (3-6 years of age).

Evidence to validate the use of fixed-time (FT) reinforcer delivery (i.e., noncontingent reinforcement) with typically developing populations has been relatively rare in the behavioral literature. In those studies that have provided validation, reinforcer delivery schedules appeared to be prohibitively dense for sustained implementation of…

This research synthesis verifies the effectiveness of the Picture Exchange Communication System (PECS) for improving the functional communication skills of individuals with autism spectrum disorders (ASD). The research synthesis was focused on the degree to which variations in PECS training are associated with variations in functional…

There is a great need to identify specific instructional methods that effectively promote positive skill development in young children with developmental disabilities. One method that has received strong empirical support with children with autism is Discrete Trial Teaching (DTT); however, the effectiveness of DTT has not been extensively…

The Early Development Index (EDI) is a teacher-completed checklist, intended to be a population-level tool to measure children's readiness for school and to alert communities to potential developmental problems in children. In response to the increasing popularity of the EDI, this paper provides a critical and timely evaluation and identifies the…
