You are working in a private ABA clinic with a client, Ali, who is 17 years old, 6 feet tall, and weighs 200 pounds. Ali engages in very dangerous self-injury consisting of banging his head against hard objects with enough force to cause tissue damage. A functional analysis was conducted, and it has been found that the behavior is multiply maintained by staff attention as well as escape from demands. The clinical team has been trying to treat the behavior for over a year with limited success and has exhausted all of their function-based treatment options including FCT, DRO, DRI, and antecedent strategies. Ali's parents and school have consented to adding punishment to function-based treatment. Describe what function-based treatment might consist of for Ali and how you would add punishment to the treatment package. Be sure to explain what the punisher would be, how it would be determined, and how it would be applied (schedule, intensity, by whom, for how long, etc.). What safeguards would you put in place to ensure that the procedure is done ethically and safely?
