What type of interview is designed to evoke in-depth responses from clients?

The type of interview designed to evoke in-depth responses from clients is the unstructured interview. This format allows for open-ended questions and a conversational style, encouraging clients to express their thoughts, feelings, and experiences in greater detail. It creates an environment where clients feel more comfortable to share personal insights, leading to richer and more nuanced information.

In contrast, structured interviews have a predetermined set of questions with a fixed format, which can limit the depth of responses. Standardized interviews follow specific guidelines and scoring criteria, aiming for consistent data collection but at the expense of exploring personal narratives. Closed interviews, which use questions that typically require a simple 'yes' or 'no' answer or other limited responses, also restrict the depth of engagement and personal expression. Therefore, the unstructured format is particularly effective in contexts where understanding the client's unique perspective is essential.
