• Test-retest reliability of lifetime anxiety disorder diagnoses was determined using the Schedule for Affective Disorders and Schizophrenia-Lifetime Anxiety version. The subjects were 104 patients at an anxiety research clinic. Reliability ranged from good to excellent (kappa = +.60 to +.90) for generalized anxiety, social phobic, panic, agoraphobic, and obsessive-compulsive disorders. Simple phobia showed poor agreement. Current episodes showed better agreement than past episodes, particularly for social phobia and obsessive-compulsive disorder. Major sources of disagreement (variance in subject report, rater error, criterion ambiguity) were reviewed for each diagnosis and implications for DSM-IV are proposed.
