When is it appropriate to use structured clinical interviews versus unstructured interviews?

• A. Structured interviews improve reliability and coverage for diagnostic assessment; unstructured interviews allow exploration and flexibility
• B. Unstructured interviews are more reliable and comprehensive
• C. Structured interviews are only for employment interviews
• D. Unstructured interviews are always preferred for accuracy

Answer: (A)

Structured clinical interviews standardize questions and scoring, which boosts reliability and ensures systematic coverage of diagnostic criteria across cases. This makes them ideal for diagnostic assessment where consistency and comparability are important. Unstructured interviews allow the clinician to guide the conversation, build rapport, and follow topics that emerge in the moment, yielding richer, contextual information that a fixed script might miss. In practice, many clinicians use semi-structured formats to combine the benefits of both: maintaining reliability and thoroughness while still allowing exploration of individual concerns. The other statements misstate the trade-offs—unstructured interviews aren’t inherently more reliable or comprehensive, structured interviews aren’t limited to employment contexts, and unstructured interviews aren’t always more accurate.
