Single-Case Design Research Methods Brief

This brief from the Home Visiting Evidence of Effectiveness (HomVEE) review defines a single-case design (SCD), illustrates common types of designs, and details the benefits and drawbacks of conducting SCD research. Studies that use an SCD measure outcomes for cases (such as a child or family) repeatedly during multiple phases of a study to determine the success of an intervention, such as an early childhood home visiting model.

Further details about how the HomVEE review applies review standards and U.S. Department of Health and Human Services (HHS) criteria for an evidence-based early childhood home visiting service delivery model to single-case design research in the home visiting field are available in the HomVEE Version 2.1 Handbook.
