multielement design with a baseline #21

Please leave suggestions for single-case or small-n studies using a multielement (alternating treatment) design with a baseline. These designs are hybrids of the reversal and multielement designs.

Consider Deshais et al (2018; https://doi.org/10.1002/jaba.505), A comparison of group contingencies on academic compliance. Here's the abstract:

We used a reversal design with an embedded multielement design to compare the effects of an independent group contingency and a randomized dependent group contingency on compliance with assigned literacy worksheets in a first-grade general education classroom. Nine participants were selected based on low levels of compliance in baseline or by teacher identification. Results indicated that both group contingencies increased compliance relative to baseline for the majority of participants. The independent condition produced higher levels of compliance for four students and the randomized dependent condition produced higher levels of compliance for one student. For four students, the two group contingencies were equally effective. A preference assessment indicated that the majority of target students preferred the randomized dependent condition and the majority of nontarget students preferred the independent condition. A number of potential explanations for our preference findings, including the possible role of obtained reinforcement, are discussed.

This is an n = 9 multielement design with a baseline where the criterion "percentage compliance" and the number of trials upon which the percentages were based varied. This could make for a nice binomial analysis, where n varies across participants and occasions. However, you would need to simulate the n values based on the means and ranges on page 4.
