Discussion of the reliability and validity of an interview is thorough and detailed. It frequently takes the form of a mini meta-analysis of the empirical data. A table contains information about the setting of each study (inpatient, outpatient, community, or university), the number of diagnoses covered in the study, whether the raters were laypersons or professionals, what kinds of tests of reliability were reported (interrater or retest), and the actual reliability estimates, divided into categories for symptoms, current diagnosis, lifetime diagnosis, and other. When enough data are available, a separate table of the validity studies is also provided, indicating the version of the interview studied, the number of participants in the study, and the kinds of disorders for which a kappa statistic estimate of the validity was reported. Whenever possible, evidence for the concurrent, predictive, construct, and divergent validity of the instrument is considered, including computerized versions of the measure when data are available.
