Two clinical validation studies on the State form and types of reliability of the trait form of the State-Trait Anxiety Inventory

Abstract

To determine the "real life" validity of the State form (experimental B-1 and final X-1) of the State-Trait Anxiety Inventory, two P-technique analysis studies were carried out. The first utilized two therapists and two of their respective clients. The second involved two patients on an alcoholic treatment unit and their therapists. Expected relations in the first study between clients' responses to the STAI B-1, a separate Daily Diary, and therapists' judgments were not entirely forthcoming. However, the second study showed expected correlations between measures of psychophysiological functions, psychological tests, and the clinicians' judgement. Several reliability indices applied to the Trait form (B-2 and X-2) showed considerable relation between two administrations two months and one month apart respectively.
