DISCUSSION
Between these subtly defined groups of high anxiety with medium depression and high anxiety with high depression as defined by Zung score, characteristic differences in daily activities and temporal aspects of anxiety and depression may be found using ES. This is particularly true for data at the behavioral level representing activities selected by the subjects in each group, and at the temporal level in terms of each group’s differential capacity to recover and rebound from high anxiety and depressed mood episodes. ES separated the groups on self-report scores of thought content, psychopa-thology, and time allocation of activities. Mean self-report scores of moment-to-moment mental states did not separate the groups nor did the situations in which they occurred. This finding suggests that anxious depression is relatively context independent. Further, behavioral changes seem a stronger indicator of changes in mental state than average scores of changes in the self-perception of state. Although much of the data presenting temporal relationships in this chapter are exploratory, we may tentatively conclude from the two findings, the slow decay of anxiety in the high depression group and the predictive trend of mood for anxiety, that depression in a day-to-day sense renders an individual more sensitive to anxiety. The basic pathological process in the phenomenology of anxious depression may therefore be depression. Although it may be a measurement artifact inherent in the Zung or Spielberger ratings, it is interesting to note in the context of this volume that in the sequential sample of 15 anxiety admissions reported here, none had a low depression score. The findings presented, when pursued further and in large samples, could lead us to a more comprehensive description of the phenomena of depression and anxiety in temporal and contextual terms. Such findings may not only be useful in solving current diagnostic controversies, but may also be useful in providing new avenues for treatment based on the frequency of the occurrence of the actual illness phenomenon, its context, and its temporal recovery properties. Such in-formation should be of significance to the clinician and the psychopharmacolo-gist alike.
