Final answer:
A structured interview can provide a diagnosis and classify symptoms into a DSM disorder.
Step-by-step explanation:
A structured interview can indeed provide a diagnosis on which to further base treatment or classify the client's symptoms into a DSM disorder. In a structured interview, the interviewer asks the same set of questions to every candidate, and the questions are prepared in advance. The interviewer then uses a standardized rating system to evaluate each response. This approach allows for accurate comparison of interviews and aids in the diagnosis and classification of mental disorders.
