Additional randomization test procedures for the changing criterion design

The single-point and range-bound changing criterion design have been proposed as single-case experimental designs. The only form of randomization currently available for these designs is phase change moment randomization. The present article describes two novel randomization procedures for changing criterion designs, the blocked alternating criterion randomization and randomized alternating criterion randomization, and illustrates their use. Appropriate randomization procedures are introduced for situations in which it is desirable to maintain the stepwise nature of the changing criterion design and situations in which the change in the dependent variable can be assumed not to follow the stepwise pattern. The article further discusses contexts in which each of the randomization procedures for the changing criterion design may be useful, and explains how the procedures maintain the researcher's flexibility.

Automated summary

This article introduces two novel randomization procedures for single-point and range-bound changing criterion designs, and explains how to use them. It also discusses the applicability of each randomization procedure in different contexts, and explains how these procedures maintain the researcher's flexibility.
