Which questioning technique allows for a wide range of responses?

The technique that allows for a wide range of responses is open-ended questions. These questions encourage the responder to elaborate on their thoughts and feelings, rather than simply providing a brief or one-word answer. By using open-ended questions, a practitioner can gather more detailed information, encourage discussion, and understand the respondent's perspective more fully.

For example, asking someone "Can you tell me about your experience with pain?" allows the individual to share their personal experiences and insights in their own words. This can lead to richer, more comprehensive information that can be critical in many contexts, such as assessing patient health or understanding a situation more deeply.

In contrast, leading questions typically suggest a desired response, limiting the answer choices, while closed questions require a specific, often one-word answer, and probing questions delve deeper into a specific response rather than inviting broad discussion.
