On the Decline of n = 1 Research in Behaviour Change: The Rise of the Evidence-Based Practice Movement as One Explanation for the Trend Academic Article uri icon


  • AbstractParadoxically, the rise of the evidence-based practice (EBP) movement with its growing reliance on the execution of randomised controlled trials (RCTs) has been associated with a fall in the conduct of single-case research. Sharpley, among others, is concerned with this trend because it ignores the complementarity of single-case and group experimentation. We argue that the view that EBP should be founded predominantly on group data is untenable on both scientific and practical grounds.
