What We Do

Travers, Maggin, and Cook will conduct a replication of Sham and Smith’s (2014) review examining publication bias in single-case design research.

Sham and Smith (2014) compared points of nonoverlapping data between published studies and unpublished dissertations using experimental single-case designs to examine the effects of pivotal response therapy for individuals with autism. They found that published studies had, on average, 22% more nonoverlapping data points than unpublished dissertations. They replication study will use a variety of effect sizes to evaluate differences between published and unpublished research.
