We found the point prevalence (one month) of one or more depressive symptoms in the general population, excluding respondents with major depression/dysthymia (MD/D), was extremely high at 19.6%. The one-year prevalence of two or more depressive symptoms in the general population, excluding MD/D, was 11.8% (N = 1213). We have labeled this potential clinical condition as Subsyndromal Symptomatic Depression (SSD). The most frequent depressive symptoms reported in SSD are insomnia (40.6%) fatigue (37.8%), recurrent thoughts of death (33.0%), 14-day depressed mood/anhedonia (DSM-111 A criterion) (30.4%), trouble concentrating (22.2%), and significant weight gain (16.2%). SSD sample had many characteristics similar to MD/D, but was distinctly different from the population with no depressive symptoms. Most notably, on variables of negative/adverse outcome, SSD significantly exceeded the no depressive symptoms subsample with higher prevalence of receiving social security benefits, public-assisted disability and lifetime suicide attempts. We found that 27% between these two subsamples of SSD also qualified for DSM-IV Minor Depression. The difference between these two subsamples of SSD is the presence of the DSM-III A Criterion (14 days depressed, sad mood, anhedonia) which is necessary for the diagnosis of Minor Depression. We now propose to redefine SSD as follows: the presence of any two or more depressive symptoms, at least 14 days in duration, excluding individuals who qualify for diagnosis of Minor Depression, Major Depression/Dysthymia. Using this definition, the new SSD subsample has a one-year prevalence of 8.4% in the general population. Approximately 60% of these SSD patients have only two depressive symptoms, the remainder have three or more. SSD, without Minor Depression is associated with increased social disability and dysfunction, including 10.1% lifetime prevalence of suicide attempts — a prevalence level that is 10 times the rate in the general population. SSD is a very intriguing and potentially very important subthreshold form of mood disorder which is deserving of further study and characterization.
