Document Summary
Advantages the interviewer can control the interaction and can probe further when necessary. By observing the patient"s nonverbal behavior, the interviewer can try to detect areas of resistance; in that sense, the validity of the information may be enhanced. An interview can provide a lot of information in a short period of time; it can cover past events in many different settings limitations. Some patients may be unable or unwilling to provide a rational account of their problems. Advantages rating scales are primarily useful as an overall index of symptom severity or functional impairment. Behavioral coding systems provide detailed information about the person"s behavior in a particular situation limitations. Observational procedures can be time-consuming and therefore expensive. Observers can make errors; their perception may be biased; the reliability of ratings as well as behavioral coding must be monitored reactivity: people may alter their behavior when they know they are being observed.
