Behavior By Design

Introduction

Applied Behavior Analysis (ABA) is guided by the seven dimensions first described by Donald M. Baer, Montrose M. Wolf, and Todd R. Risley in their seminal 1968 article, Some Current Dimensions of Applied Behavior Analysis. These dimensions continue to serve as the foundation for determining whether an intervention truly reflects ABA principles. The dimensions are Applied, Behavioral, Analytic, Technological, Conceptually Systematic, Effective, and Generality. Together, they ensure that interventions are socially meaningful, scientifically sound, and produce lasting behavior change.

For this analysis, an intervention program targeting physical aggression maintained by escape from academic demands will be evaluated. In this intervention, a student engages in physical aggression when presented with classroom work. The intervention includes functional communication training (FCT), differential reinforcement of alternative behavior (DRA), visual schedules, and graduated task demands.

The Seven Dimensions of ABA

1. Applied

The applied dimension focuses on behaviors that are socially significant and important to the individual and those around them. Rather than studying behavior solely for theoretical purposes, ABA addresses behaviors that improve quality of life and functioning (Baer et al., 1968; Cooper et al., 2023).

Application to the Intervention

The target behavior—physical aggression during academic tasks—is highly socially significant because it interferes with learning, classroom participation, and safety. Reducing aggression and increasing appropriate communication directly improves the student’s educational experience.

Evaluation: Strong alignment with the Applied dimension.

2. Behavioral

The behavioral dimension requires that the behavior being targeted is observable and measurable. Behavior analysts focus on what people do rather than on inferred internal states (Cooper et al., 2023).

Application to the Intervention

Physical aggression can be operationally defined as hitting, kicking, pushing, or attempting to strike another person. Replacement behaviors, such as requesting a break appropriately, can also be directly observed and measured.

Evaluation: Strong alignment with the Behavioral dimension because both target and replacement behaviors are clearly observable and measurable.

3. Analytic

The analytic dimension demonstrates a functional relationship between the intervention and behavior change. Changes in behavior must be shown to result from the intervention rather than from extraneous factors (Baer et al., 1968).

Application to the Intervention

Data are collected on aggression and appropriate requests before and after implementation of FCT and DRA. A single-case design, such as an ABAB reversal or multiple-baseline design, could demonstrate that reductions in aggression occur only when the intervention is implemented.

Evaluation: Moderate alignment. The intervention would fully meet this dimension only if experimental control is demonstrated through systematic data analysis.

Suggested Improvement

Use a multiple-baseline or reversal design to verify that behavior changes are directly attributable to the intervention.

4. Technological

The technological dimension requires that procedures are described clearly enough for another practitioner to replicate them accurately (Baer et al., 1968).

Application to the Intervention

Procedures should specify:

• The operational definition of aggression
• When academic demands are presented
• How prompting is delivered
• The exact reinforcement schedule
• Criteria for providing breaks
• Data collection procedures

Evaluation: Partial alignment. The intervention may not fully meet this dimension if implementation procedures are not written in sufficient detail.

Suggested Improvement

Develop a written treatment protocol and procedural checklist to ensure consistency across staff.

5. Conceptually Systematic

Interventions should be based on established behavioral principles rather than a collection of unrelated techniques (Cooper et al., 2023).

Application to the Intervention

The procedures are grounded in behavioral principles:

• FCT teaches a functionally equivalent communication response.
• DRA reinforces appropriate behavior while withholding reinforcement for aggression.
• Escape extinction and demand fading are based on reinforcement principles.

Evaluation: Strong alignment because all procedures are derived from behavioral theory.

6. Effective

An intervention should produce meaningful and practical behavior change. The magnitude of improvement must be socially important rather than merely statistically significant (Baer et al., 1968).

Application to the Intervention

If aggression decreases from ten incidents per day to one incident per week and the student completes classroom assignments successfully, the intervention demonstrates meaningful effectiveness.

Evaluation: Strong alignment if substantial reductions in aggression and increases in task engagement are achieved.

Suggested Improvement

Incorporate social validity measures by obtaining teacher, parent, and student feedback regarding the importance and acceptability of outcomes.

7. Generality

The generality dimension requires behavior change to maintain over time and transfer across settings, people, and situations (Baer et al., 1968).

Application to the Intervention

The student should continue using appropriate communication:

• In different classrooms
• With different teachers
• During homework activities
• Weeks or months after intervention ends

Evaluation: Currently limited because generalization programming has not been explicitly described.

Suggested Improvement

Train multiple staff members, practice skills across settings, and conduct maintenance probes to assess long-term outcomes.

Overall Program Evaluation

ABA Dimension	Alignment	Evidence	Improvement Needed
Applied	Strong	Addresses aggression affecting learning and safety	None
Behavioral	Strong	Observable and measurable behaviors identified	None
Analytic	Moderate	Data collection planned but experimental control not specified	Use single-case experimental design
Technological	Moderate	Procedures described generally	Develop detailed written protocol
Conceptually Systematic	Strong	Based on reinforcement and functional relations	None
Effective	Strong	Targets meaningful behavior change	Include social validity measures
Generality	Limited-Moderate	Maintenance and generalization not fully addressed	Program for transfer across settings

Critchfield and Reed’s Perspective

Critchfield and Reed (2017) argued that ABA research often exists on a continuum rather than fitting neatly into the seven-dimension framework. They suggested that ABA should not be viewed as a rigid category but rather as a field characterized by varying degrees of alignment with the dimensions. Their analysis highlights that some interventions may strongly satisfy several dimensions while only partially meeting others. Therefore, practitioners should continuously evaluate and refine interventions rather than assuming they qualify as ABA simply because behavioral procedures are used.

The intervention evaluated here illustrates this point. While it strongly meets the Applied, Behavioral, Conceptually Systematic, and Effective dimensions, improvements are needed in Analytic, Technological, and Generality dimensions to fully reflect high-quality ABA practice.

Conclusion

The seven dimensions of ABA provide a framework for evaluating the quality and effectiveness of behavior analytic interventions. The intervention targeting physical aggression maintained by escape from academic demands demonstrates strong alignment with several dimensions, particularly Applied, Behavioral, Conceptually Systematic, and Effective. However, improvements in experimental demonstration of behavior change, procedural specificity, and generalization planning would strengthen its adherence to the full ABA framework. As emphasized by Critchfield and Reed (2017), practitioners should view the dimensions as guiding principles that support ongoing refinement of behavior analytic practice rather than as a simple checklist.
