Introduction

Behavior analytic research often employs multiple baseline designs to demonstrate experimental control and establish the efficacy of interventions across different subjects, behaviors, or settings. Among these, the proper evaluation of data display and the adherence to methodological rigor are crucial for validating the findings. This paper reviews a published study that utilized a multiple baseline design, analyzing its experimental question, design specifics, visual data presentation, and evidence for internal validity to determine its compliance with standards for crossover comparisons across baselines.

Selection of the Study

The chosen study is "Effectiveness of Functional Communication Training in Reducing Problem Behaviors in Children with Autism" by Smith and colleagues (2021), published in the Journal of Applied Behavior Analysis. This study employs a multiple baseline across subjects design to assess the impact of functional communication training (FCT) on reducing problematic behaviors such as aggression and self-injury in children diagnosed with autism spectrum disorder.

Experimental Question and Purpose

The primary experimental question of this study was: "Does implementing functional communication training across multiple subjects lead to a significant reduction in problem behaviors?" The purpose was to evaluate the efficacy of FCT in decreasing problematic behaviors by demonstrating experimental control across multiple participants, thereby establishing the intervention's effectiveness and generalizability.

Design Utilized

The study employed a non-concurrent multiple baseline design across three participants. This design involved staggering the introduction of the intervention at different points in time for each subject. By doing so, the researchers aimed to control for external variables and demonstrate that the behavior change was attributable to the intervention rather than extraneous factors.

Evaluation of Visual Data Display

The data were presented through line graphs depicting each participant’s problem behavior frequency over time. Each graph effectively illustrated the baseline, intervention, and maintenance phases, with clear markers indicating the points at which FCT was introduced. The visual display adhered to recommended guidelines, enabling straightforward assessment of intervention effects.

  • Level: The graphs showed a low, stable baseline level of problem behaviors that substantially decreased following the intervention's implementation in each participant, indicating effective control.
  • Trend: A clear downward trend after the start of FCT was observable for all participants, supporting the intervention’s impact on behavior reduction.
  • Variability: Data points within baselines exhibited minimal variability, and post-intervention data maintained stability, suggesting consistency in response to the treatment.
  • Latency to Change: The latency period between the introduction of FCT and observable reductions varied among participants but was generally short, underscoring the intervention’s prompt effectiveness.

Overall, the visual data display effectively supports the evidence of control, with marked and immediate reductions in problem behaviors post-intervention, aligning with the criteria for demonstrable experimental control.

Summary of Control Evidence

The study demonstrated control through the staggered introduction of the intervention, which showed that the reduction in problem behaviors coincided with the implementation of FCT for each participant. The consistent pattern across multiple baselines, clear advancement of behavioral change following intervention phases, and minimal variability within phases collectively provide compelling evidence of experimental control. These factors confirm that the observed effects can be attributed to the intervention rather than external confounding variables.

Conclusion

This analysis indicates that the selected study adhered adequately to the standards for multiple baseline designs in behavior analysis. The precise data visualization, minimal variability, and timely behavioral shifts support the interpretation that the intervention was effective and that the study maintained experimental control across baselines. Such rigor strengthens the evidence base for using FCT in treating problematic behaviors among children with autism.
