SDS
The Zung Self-Rating Depression Scale (SDS) (1) was used to assess the degree of depression. The SDS has been criticized by some researchers (2), but with the following minor modifications it served our punpose. First, before the test, we gave the following specific instructions to our subjects. Answer all questions as they apply to you. Ifyou feel an answer should be ‘none of the time,’ check the space ‘a little of the time’ ; if you feel an answer should be ‘all of the time,’ check ‘most of the time. We felt these instructions would allow us to compare our data with other studies using the SDS while reducing the number of questions ‘ ‘
RECENT YEARS there has been much research on various aspects of depression. Studies on the psychology, epidemiology, sociology, and neurobiology of depression are prominent in the psychiatric and related literature. Studies of subclinical depression are less frequent. We were interested in assessing a “normal” population to determine 1) the extent of depression in such a sample, 2) the possible correlation between depression and physical illness, and 3) possible sex differences in respect to these and other variables. IN
Sample The sample consisted of blue collar workers in a small rural factory where the males and females had identical occupations and similar backgrounds. Of 200 workers asked to participate, 159 responded to the first questionnaire (84 females and 75 males). Of these, 114 also took the second test (61 females and 53 males). There was a wide age range, 16-52 years, with a mean age of 28 years. Educational levels of the subjects ranged from seventh grade to 1 year of college.

In order to assess the relationship between depression and physical illness, we correlated the SDS with absenteeism and visits to the plant health service (categorized as visits for injury or for illness). The SDS was administered at the factory by a mcdical student. There was a 38-day interval between the two

periods.
