A social worker will experience a dramatic positive change in his or her interviewing style and confidence level by incorporating:

A) ​open-ended responses.
B) ​closed-ended responses.
C) ​minimal prompts.
D) ​simple reflections.

Open-ended responses allow for more detailed and expansive responses, which can lead to deeper conversations and greater insight into the client's needs and experiences. This can increase the social worker's confidence in their ability to gather relevant information and build rapport with the client. Closed-ended responses may limit the amount of information that is shared and can be perceived as less collaborative, while minimal prompts and simple reflections are helpful but may not have as significant an impact on the social worker's interviewing style and confidence level.
