Final answer:
The component of BST that determines the most impact on which way intervention was delivered is the skills being taught.
Step-by-step explanation:
The component of BST (Behavioral Skills Training) that determines the most impact on which way intervention was delivered is the skills being taught. In BST, the skills being taught are broken down into smaller, manageable steps, and then systematically taught and reinforced. The effectiveness of the intervention depends on how well these skills are identified, broken down, and taught to the individuals.
