What do structured interviews specifically limit in terms of data collection?

Structured interviews are designed with a specific set of predetermined questions that are asked in a systematic order. This approach inherently limits both the amount of interaction and the depth of exploration during the interview process.

With regards to interaction, structured interviews usually have a rigid format that restricts the interviewer's ability to engage in a conversational style or to explore topics that arise spontaneously. This can result in a more mechanical interaction between the interviewer and the participant, as the focus remains strictly on the questions that were planned in advance.

Additionally, the depth of exploration is constrained because the structured format does not permit follow-up questions or digressions that might lead to deeper insights. Unlike unstructured interviews, where the interviewer can probe further based on the responses given, structured interviews are limited to the specific questions asked. This means that nuanced or complex topics may not be fully addressed, leading to a potentially superficial understanding of the participant's experiences and viewpoints.

Thus, the correct answer reflects the limitations imposed by the structured nature of these interviews, which curtail both the richness of interaction and the depth of the exploration of responses.
