2018 TASH Conference has ended
Each year, the TASH Conference brings together a diverse community of stakeholders who gain information, learn about resources, and connect with others across the country to strengthen the disability field. This year’s conference theme, “Be Creative - Innovative Solutions for an Inclusive Life,” reminds us to think outside the box during times of uncertainty. Creativity, innovation, and determination can pave the way for meaningful and inclusive lives for people with disabilities.

This meta-analysis examined the efficacy progressive time delay (PTD) prompting to teach students diagnosed with moderate to severe disabilities (e.g., intellectual disabilities with a reported IQ below 55, severe autism, deafblind). 30 research studies published in peer reviewed journals were reviewed using criteria for evidence-based research practices delineated by Horner, Carr, Halle, McGee, Odom, and Wolery (2005). 17 studies met criteria for further review (two with two studies each; total of 19). The majority of studies taught sight words (five) or identification of photos (four); the remaining 10 studies taught a variety of skills from crossing the street to verbal behavior. The majority of the studies (17 of 19) reported significant effect sizes (i.e., PND), which is indicative of PTD's utility as a prompting strategy when teaching a wide array of skills. However, in regard to teaching specific skills, PTD requires more research to qualify as an evidence-based practice (e.g., to state PTD is effective to teach X skill); that is, to meet Horner et al, 2005, criteria for research to be considered evidence-based.
