A statistical analysis of the classification of depression in a mixed community and clinical sample

High anxiety is associated with an increased risk of death in an older tri-ethnic population

“…In older populations, rates of comorbidity vary depending on the psychiatric disorder. For example, in a study of older adults hospitalized for depression 67% also reported symptoms of anxiety [34]. In older persons with major depression living in the community, Beekman et al [35] reported an anxiety prevalence rate of 47.5%.…”

Using the conditional grade-of-membership model to assess judgment accuracy

“…Manton, Woodbury, and Tolley (1994) have developed a general grade-of-membership (GoM) model that extends the latent class framework to include the identification of objects as mixtures of an arbitrary number of latent nominal categories. This general GoM model has been used in a wide range of empirical applications to determine latent mixtures from high dimensional discrete multivariate data (e.g., Berkman, Singer, & Manton, 1989;Blazer et al, 1989;Ventrees & Manton, 1986;Woodbury & Manton, 1982).…”

The epidemiology and presentation of depression in the elderly

“…While community surveys confirm that DSM-III-R major depression is identified among the elderly, when usual case finding methods are applied across the life cycle (Blazer, 1989), it is the variants of classical major depression among the elderly that cause a problem.…”

“…At present the syndrome would have been classified under the DSM-III-R diagnosis of depressive disorder not otherwise specified, or atypical depression. However the authors felt that "m inor depression" would be one way of classifying such subjects (Blazer, 1990;Blazer, Woodbury & Hughes et al, 1989).…”
