Backward Chaining is a technique used in applied behavior analysis to teach complex tasks by breaking them down into discrete responses or individual behaviors that are part of a task analysis.[1][2] In a backward chaining procedure, a sequence of steps is taught beginning with the last step and adding previous steps as each is mastered.[1][2][3] The reinforcement consistently being delivered for finishing the task may help to maintain the learner's motivation. [1][2] Because independence is desired, the goal is to remove the prompts as soon as the learner can complete the steps without help.

Task Analysis

edit

A task analysis involves breaking a complex skill into smaller, teachable units creating a series of steps.[1][2] In backward chaining, it is used to identify the sequence of steps so the final response may be targeted first.[1][2]

Procedure

edit

Teaching begins with the final step of the task.[1][2][4] Once that is mastered, the preceding step is introduced and the pattern follows until the task is fully mastered.[1][2][3] Prompts are gradually removed as the learner masters each step, promoting independence.[1][2][4]

Example

edit

In handwashing, the instructor would complete all levels of the task for the learner up to the final step, which would be turning off the faucet.[2][4] Once the learner can perform the final step independently, the instructor then teaches the preceding step, which is drying hands.[1][2] This pattern continues until the learner can independently perform the entire task.[1][2]

Application

edit

Backward chaining is commonly used in applied behavior analysis to teach complex skills. [2][5] Some examples of functional skills taught with this procedure are washing hands, brushing teeth, dressing, cooking, and cleaning. [1][5] It can also be used to develop communication methods, like the Picture Exchange Communication System. [6]

Research shows that backward chaining is an effective way to help individuals with developmental disabilities learn multi-step tasks.[5] While some studies compare forward and backward chaining, there is no conclusive evidence to show that learners prefer one method over the other. [1][3] Preference is usually up to the specific individuals who are teaching or being taught the intervention.[1]

Research

edit

Backward chaining is primarily studied in applied behavior analysis to evaluate its effectiveness in teaching multi-step tasks.[3][5] Research shows that individuals with developmental disabilities learn functional skills successfully with this method.[5] Studies comparing backward chaining with forward chaining show both as effective methods of learning.[1][3]

Advantages and Limitations

edit

An advantage of backward chaining is that the learner immediately accesses reinforcement for completing the task.[1][2] It also reduces the effort it takes to respond in early trials, helping the learner to gain momentum.[2] This method also supports the development of independent responding by fading out prompts.[1][2]

However, backward chaining is often inefficient for learners who can already perform earlier steps of the task independently.[2] It can also be more time-intensive as the instructor must complete multiple steps early on in the trials.[2] Learners also may become dependent on prompts if they are not faded in time.[1][2]
