Final answer:
Sasha, a behavioral therapist, is most likely to use applied behavioral analysis (ABA) to address Justin's self-harming behavior. ABA is evidence-based and involves teaching adaptive behaviors and positive reinforcement to reduce undesirable behaviors like self-harm.
Step-by-step explanation:
The most likely technique to be implemented by Sasha, a behavioral therapist, to curb Justin's self-harming behavior is applied behavioral analysis (ABA). ABA is a well-established and evidence-based behavioral intervention that is often used for children with autism. This approach utilizes positive reinforcement and structured teaching methods to help individuals with autism learn new behaviors and reduce undesirable behaviors like self-harm.
ABA therapy would involve an assessment of Justin's self-harming behavior to identify its function or cause. This would be followed by the implementation of behavioral interventions specifically designed to address the identified function. These interventions might include teaching alternative, more adaptive behaviors, modifying the environment to reduce triggers for self-harm, and providing reinforcement when Justin engages in positive behaviors.
It is important to note that while other therapies, such as client-centered therapy, can offer a supportive environment, and aversive conditioning involves the application of negative consequences to decrease a behavior, ABA is the most commonly and effectively used approach to address behavioral issues in individuals with autism.
