If a patient cannot finish the PsychDiagnoser or mini PsychDiagnoser interview it can be resumed. Computers are extremely reliable. Unlike humans, computers will do the same thing, no matter how mundane, indefinitely and consistently. Computers do not have bad days and software does not wear out. A physician can rely on a computer to question and execute diagnostic decision logic in the same way repeatedly.
Computers present all questions in an impartial and unemotional manner.
Computers do not show change in tone of voice, have facial reactions or make value judgments. Unlike computers, both patients and interviewers may be reluctant to discuss sensitive issues such as sexuality and substance abuse. Testing with diagnostic software has shown that many patients felt more comfortable revealing sensitive or confidential information such as about sexuality or substance abuse to an impersonal computer than to a physician. Many patients admitted to revealing more information to the computer interview than the clinician. Computer are not good at inference-based logic.
