Subthreshold depression as a risk indicator for major depressive disorder: a systematic review of prospective studies

ACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2004
P. Cuijpers
Objective:, In order to examine whether the incidence of major depressive disorder (MDD) is increased in subjects with subthreshold depression, or sD (clinically relevant depressive symptoms, without meeting criteria for a full-blown MDD), we conducted a review of prospective studies examining the incidence of MDD in subjects with sD. Method:, A systematic literature search was conducted. For all studies, the relative risk of developing MDD was calculated, based on person-years. Results:, Twenty studies (23 comparisons) were found, based on community samples, general medical patients and high-risk subjects. Most comparisons showed that subjects with sD had a consistently larger chance of developing MDD. The studies differed considerably in the definition of sD, the recency (occurrence of the last sD) and the in-/exclusion of lifetime MDD. Conclusion:, The incidence of MDD in subjects with sD is larger than in subjects without sD. Otherwise, the concept of sD is too broad to be used. In future studies, some consensus should be reached regarding the definition of sD. [source]

How many well vs. unwell days can you expect over 10 years, once you become depressed?

ACTA PSYCHIATRICA SCANDINAVICA, Issue 4 2009
T. A. Furukawa
Objective:, Prognostic studies of major depression have mainly focused on episode remission and relapse, and only a limited number of studies have examined long-term course of depressive symptomatology at threshold and subthreshold levels. Method:, The Group for Longitudinal Affective Disorders Study has conducted prospective serial assessments of a cohort of heretofore untreated major depressive episodes for 10 years under naturalistic conditions. Results:, Of the 94 patients in the cohort, the follow-up rate was 70% of the 11 280 person-months. Around 77% of the follow-up months were spent in euthymia, 16% in subthreshold depression and 7% in major depression. Duration of the index episode before reaching recovery was the only significant predictor of the ensuing well time. Conclusion:, On average, patients with major depression starting treatment today may expect to spend three quarters of the next decade in euthymia but the remaining one quarter in subthrehold or threshold depression.

Depression and Retirement in Late Middle-Aged U.S. Workers

HEALTH SERVICES RESEARCH, Issue 2 2008
Jalpa A. Doshi
Objective. To determine whether late middle-aged U.S. workers with depression are at an increased risk for retirement. Data Source. Six biennial waves (1992,2002) of the Health and Retirement Study, a nationally representative panel survey of noninstitutionalized 51,61-year-olds and their spouses started in 1992. Study Design. Workers aged 53,58 years in 1994 were followed every 2 years thereafter, through 2002. Depression was coded as lagged time-dependent variables measuring active depression and severity of depression. The main outcome variable was a transition to retirement which was measured using two distinct definitions to capture different stages in the retirement process: (1) Retirement was defined as a transition out of the labor force in the sample of all labor force participants (N=2,853); (2) In addition a transition out of full time work was used as the retirement definition in the subset of labor force participants who were full time workers (N=2,288). Principal Findings. In the sample of all labor force participants, the presence of active depression significantly increased the hazard of retirement in both late middle-aged men (adjusted OR: 1.37 [95 percent CI 1.05, 1.80]) and women (adjusted OR: 1.40 [95 percent CI 1.10, 1.78]). For women, subthreshold depression was also a significant predictor of retirement. In the sample of full time workers, the relationship between depression and retirement was considerably weaker for women yet remained strong for men. Conclusions. Depression and depressive symptoms were significantly associated with retirement in late middle-aged U.S. workers. Policymakers must consider the potentially adverse impact of these labor market outcomes when estimating the cost of untreated depression and evaluating the value of interventions to improve the diagnosis and treatment of depression.

A comparison of GMS-A/AGECAT, DSM-III-R for dementia and depression, including subthreshold depression (SD),results from the Berlin Aging Study (BASE)

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 2 2003
R. T. Schaub
Abstract Background Empirical evaluation of the agreement between different diagnostic approaches is crucial for the understanding of epidemiological results in geriatric psychiatry. Objectives In this paper, we analyse differences between widely used diagnostic approaches of dementia and depression and offer evidence that diagnostic thresholds vary substantially on quantitative dimensions, but that conceptual and other differences between approaches must also been taken into account. Methods In an epidemiological study of n,=,516 persons, aged 70,103 years, we compared psychiatric diagnoses of dementia and depression obtained by GMS-A/HAS-AGECAT, DSM-III-R and clinician's diagnoses of subthreshold depression (SD). Results For depression, cumulative prevalence of clinician's diagnosis (including SD, GMS-A/HAS-AGECAT and DSM-III-R defined forms) was highest, followed by GMS-A/HAS-AGECAT-diagnosis and DSM-III-R, while for dementia DSM-III-R was followed by GMS-A/HAS-AGECAT. Overall agreement between DSM-III-R and GMS-A/HAS-AGECAT was moderate. Adapting thresholds for AGECAT resulted in slightly better diagnostic efficiency. Diagnostic disagreement was found predominantly for cases with intermediate symptom severity, supporting the hypothesis of differing thresholds between DSM-III-R and GMS-A/HAS-AGECAT, while cases with lower or higher symptom severity were similarily seen as cases or non-cases. Conclusion Disagreement is not only caused by conceptual differences, but also different thresholds of diagnostic algorithms. Adaptation of threshold levels should be feasible, depending on the purpose of the analysis. Copyright © 2003 John Wiley & Sons, Ltd. [source]
