Dc. Hughes et al., DOES AGE MAKE A DIFFERENCE IN THE EFFECTS OF PHYSICAL HEALTH AND SOCIAL SUPPORT ON THE OUTCOME OF A MAJOR DEPRESSIVE EPISODE, The American journal of psychiatry, 150(5), 1993, pp. 728-733
Objective: The authors examined the effects of physical health and soc
ial support on 6-month outcome of a major depressive episode in 67 pat
ients who were less than 60 years old and 46 patients who were 60 year
s old or older. They hypothesized that despite their higher rate of tr
oublesome health problems, older patients would have fewer depressive
symptoms at follow-up than would younger patients. Method: The Center
for Epidemiologic Studies Depression Scale (CES-D Scale) and a modifie
d version of the National Institute of Mental Health Diagnostic Interv
iew Schedule were used to gather data from inpatients and outpatients
treated at Duke University Medical Center during a face-to-face interv
iew at baseline and over the telephone at 6-month follow-up. At baseli
ne, all patients met DSM-III-R criteria for a major depressive episode
. Data analyses included bivariate and multivariate procedures. Result
s: At baseline, the mean CES-D Scale scores of the two age groups were
similar. As expected, the mean illness index score of the older patie
nts was significantly higher and their mean impaired subjective social
support score was slightly lower than those of the younger patients.
At 6-month follow-up, the mean CES-D Scale score of the younger patien
ts was above the depressive threshold, but the mean CES-D Scale score
of the older patients was below the depressive threshold. The illness
index and impaired subjective support measures were significant predic
tors of depressive symptoms at 6 months for the younger patients but n
ot for the older patients. Conclusions: The authors conclude that olde
r depressed patients have a more favorable prognosis than younger depr
essed patients. Predictors of outcome vary by age.
