The stability of worry content was investigated in a sample of 27 individuals diagnosed with Generalized Anxiety Disorder. During an initial evaluation, participants were asked to describe the content of their current worries, and the examining psychiatrist rated the frequency and intensity of these topics. During the following year, the investigators interviewed the participants on a monthly basis assessing the intensity and frequency of original worries, intensity and frequency of new worries, overall worry level, and general anxiety level. Analysis of this longitudinal data indicated level of overall worry and anxiety remained fairly stable over a 12-month period. Although the intensity and frequency of original worries decreased over time, few original worry topics completely remitted. In fact, at the end of the 12-month monitoring period, worry content identified at baseline continued to account for over 65% of the overall worry variance. Most participants did identify new worry topics during the course of the 12-month period, and the frequency and intensity of the new worries were comparable to the decrease in frequency and intensity of the original worries.
