The State-Trait Anxiety Inventory (STAI) is one of the most widely used scales
for the evaluation of anxiety in medical and, to a lesser extent, psychiatric pa-
tients. Although there is a relatively large amount of STAI data about anxiety
for individuals with a variety of psychiatric disorders, the results of many anx-
iety studies include only state or trait and many studies have been inﬂuenced
by comorbidity and by variations in diagnostic criteria used. We studied state
and trait anxiety and compared the revised form of the STAI (Form Y) with the
original (Form X) to evaluate the anticipated improvement in the measure. In
addition, we compared the STAI results with those of another self-report mea-
sure (the Symptom Checklist–90 anxiety and depression scales) and also with
interviewer-rated measures of anxiety (Hamilton Rating Scale for Anxiety) and
depression (Hamilton Rating Scale for Depression). Results indicate that the
STAI does not clearly differentiate anxiety disorders from depressive disorders
