Relationships between thyroid indices and symptoms of anxiety in depressed outpatients.
ABSTRACT Scores on rating scales measuring symptoms of depression, panic anxiety, state anxiety, trait anxiety, and agoraphobic avoidance were correlated, using multivariate statistics, with total thyroxine- and thyrotropin-releasing hormone concentrations in outpatients with major depression. A significant inverse relationship was demonstrated between agoraphobic avoidance and total thyroxine concentrations in female patients. No other symptom ratings were significantly associated with these thyroid indices. The depressed patients scored in the clinically significant range for agoraphobic symptoms. Assessment of agoraphobic avoidance may help identify a clinically and biologically distinct subgroup of depressed patients.

ABSTRACT: 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 patients. Although there is a relatively large amount of STAI data about anxiety for individuals with a variety of psychiatric disorders, the results of many anxiety 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 measure (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 and support the use of multiple tests and of both self-report and interviewer ratings in the evaluation of anxiety and depression in psychiatric patients.Psychiatric Quarterly 02/2001; 72(3):263-76.
