This historical review explores the development of the literature base of single-case intervention research associated with the promotion of social outcomes for young children under the age of 9. Research studies are included from the seminal study conducted in 1956, continuing through 2019. Trends and patterns in study components are noted, such as changes over time in participant populations and the use of natural versus segregated and clinic settings. The evolution of research using particular social interventions is described as well as the various intervention agents used to impact social dependent variables across decades. Future research implications are discussed, including understudied components of social competence, the contextual variables that impact fidelity of implementation, and the need for continued research in natural settings using evidence-based social interventions that also are culturally and linguistically relevant for diverse and inclusive early learning settings.

To draw informed conclusions from research studies, research consumers need full and accurate descriptions of study methods and procedures. Preregistration has been proposed as a means to clarify reporting of research methods and procedures, with the goal of reducing bias in research. However, preregistration has been applied primarily to research studies utilizing group designs. In this article, we discuss general issues in preregistration and consider the use of preregistration in single-case design research, particularly as it relates to differing applications of this methodology. We then provide a rationale and make specific recommendations for preregistering single-case design research, including guidelines for preregistering basic descriptive information, research questions, participant characteristics, baseline conditions, independent and dependent variables, hypotheses, and phase-change decisions.
