What is the most intrusive prompt type in behavior intervention?

The most intrusive prompt type in behavior intervention is a full physical prompt. This type of prompting involves physically guiding the learner to complete a task or behavior. It requires direct contact and intervention, which means the learner does not initiate the behavior independently. This level of support can be necessary for teaching new skills, particularly for individuals who may struggle with independent task completion due to developmental or cognitive challenges.

In contrast, partial physical prompts involve less intrusive assistance, such as guiding a hand rather than moving the individual entirely. Verbal prompts rely on spoken instructions or cues, allowing for a more independent participation from the learner. Visual prompts provide non-verbal cues, such as pictures or written instructions, which help guide behavior without physical intervention. Each of these methods has its place in behavior interventions, but full physical prompting represents the highest level of assistance, making it the most intrusive option.
