This comparison draws in part from “Chaining” (ABA Courses), and extends it with peer-reviewed research from our library of 27,900+ ABA research articles. The decision framework, BACB ethics code references, and cross-links below are synthesized by Behaviorist Book Club.
View the original presentation →Behavior analysts implementing chaining programs face a fundamental procedural choice: forward chaining, backward chaining, or total task chaining. Forward chaining teaches the first step of the behavioral chain to mastery before adding the second, proceeding in the natural order of the task. Backward chaining begins with the final step, ensuring that the learner always experiences terminal reinforcement at the end of each training trial before working backward through the chain. Total task chaining prompts and reinforces every step on each trial without stepwise sequencing.
The applied literature in JABA has evaluated these variants across a range of populations and tasks without establishing a single universally superior method. What the research consistently suggests is that learner characteristics, task structure, and implementation context interact to determine which approach is most efficient for a given case. A backward chaining advantage found for one learner completing a self-care task may not replicate with a different learner completing a vocational task. BCBAs must therefore apply clinical judgment informed by baseline assessment, ongoing data review, and knowledge of the procedural distinctions between methods.
| Factor | Evidence-Based Approach | Traditional Approach |
|---|---|---|
| Sequence of instruction | Forward chaining: teaches steps in natural order, first to last | Backward chaining: teaches steps in reverse order, last to first |
| Terminal reinforcement contact | Forward chaining: reinforcement occurs after last mastered step, which may be early in the chain | Backward chaining: learner always completes the chain and accesses terminal reinforcement on every trial |
| Best clinical fit | Forward chaining: tasks where initial steps are simplest or where natural order is important for comprehension | Backward chaining: tasks where terminal reinforcement is powerful and final steps are easiest to master |
| Staff training demands | Forward chaining: staff must identify the mastery criterion step and prompt remaining steps accurately | Backward chaining: staff must implement the entire preceding chain and then focus instruction on the target step |
| Data collection complexity | Forward chaining: step-level data focused on the current instructional step; prior steps tracked for maintenance | Backward chaining: step-level data focused on the current target step; completed steps performed independently |
| Generalization considerations | Forward chaining: early mastery of initial steps may support partial-chain generalization in natural settings | Backward chaining: full-chain exposure on every trial may support generalization of the complete chain from the start |

Use this framework when approaching chaining in your practice:
Does the data support a need for intervention? Is there a meaningful impact on the individual's quality of life, safety, or access to reinforcement?
YES → Proceed to assessment NO → Document reasoning, monitor
A functional assessment should guide intervention selection. Avoid defaulting to standard protocols without individual analysis. Consider environmental variables, setting events, and private events.
YES → Select evidence-based approach matched to function NO → Complete assessment first
Goals should be co-developed. Assent and informed consent are ethical requirements. The individual's preferences and values matter in selecting both goals and methods.
YES → Proceed with collaborative plan NO → Engage in shared decision-making
This course covers the clinical and ethical dimensions in detail with structured learning objectives and CEU credit.
