Backward chaining is the most appropriate procedure in this scenario because it allows the client to escape the task immediately after completing the final step of the chain In backward chaining the practitioner prompts the client through all steps of the chain except for the very last one Once the client completes the final step independently they receive reinforcement in this case escape This method is particularly effective for individuals with escapemaintained behaviors because they experience reinforcement for completing the most difficult unprompted step making the entire chain less aversive over time as more steps are added from the end If forward chaining were used the client would need to complete the first step then the first two and so on which could lead to significant escape behaviors early in the chain Total task chaining would require the client to complete the entire chain independently from the beginning which is likely to result in high rates of escape A behavior chain interruption strategy is typically used after a chain has been established to evoke novel responses or to assess problemsolving skills not for initial teaching when escape is a primary concern
