Questionable and Improved Research Practices in Single-Case Experimental Design: Initial Investigation and Findings.

Abstract

Researchers have identified questionable research practices that compromise replicability and validity of conclusions. However, this concept of questionable research practices has not been widely applied to single-case experimental designs (SCED). Moreover, to date researchers have focused little attention on improved research practices as alternatives to questionable practices. This article describes initial steps toward identifying questionable and improved research practices in SCED. Participants were 63 SCED researcher experts with varying backgrounds and expertise. They attended a 1-day virtual microconference with focus groups to solicit examples of questionable and improved research practices at different stages of the research process. A qualitative analysis of over 2,000 notes from the participants yielded shared perspectives, resulting in 64 pairs of questionable and improved research practices in SCED. Our results highlight the need for further evaluation and efforts to disseminate improved research practices as alternatives to questionable practices.
