Worry themes in primary GAD, secondary GAD, and other anxiety disorders.

This study examines worry themes among 87 anxiety disorder patients divided into three groups: (a) 24 primary generalized anxiety disorder (GAD) patients, (b) 25 secondary GAD patients, and (c) 38 other anxiety disorder patients (primarily obsessive-compulsive disorder, social phobia and panic disorder with agoraphobia). Structured and free-recall measures were used to measure five worry themes: relationships, work, finances, physical threat, and the future. Both types of measures revealed that GAD patients worry more about the future than non-GAD patients. Further, post hoc analyses testing for linear relationships indicated that primary GAD patients worry more about the future than secondary GAD patients who in turn worry more about the future than other anxiety disorder patients. The results suggest that although worry about immediate problems may not differentiate GAD patients from other anxiety disorder patients, high levels of worry about future events may be a distinguishing feature of GAD.
