• With the use of life tables to describe time while patients were well and subsequent rates of relapse for 75 patients after their recovery from an episode of major depressive disorder in a naturalistic study, a high risk of relapse was detected shortly after recovery. Twenty-four percent of patients relapsed within 12 weeks at risk, and 12% of patients relapsed within four weeks at risk. The presence of an underlying chronic depression and three or more previous affective episodes predicted a ...

Although ‘ ‘double depression ‘ ‘-major depressive disorder superimposed on an underlying chronic depression-is a f requent phenomenon, the concept has not been well formulated clinically and has rarely been described in the research literature. The authors found that 1) 26% of 101 patients who met the criteria for major depressive disorder had an underlying chronic depressive disorder of at least 2 years’ duration, 2) “recovery” ratesfor patients with superimposed depression differed greatly de...

• Regression models and life tables were used to describe the phenomenon of recovery from major depressive disorder for 101 patients in a naturalistic study in which treatment was not controlled by the investigators. Time to recovery from the onset of the episode was protracted, as only about 50% of patients recovered by one year. Annual rates of recovery then declined steadily to 28% in the second year, 22% in the third year, and 18% in the fourth year. In contrast, speed of recovery from entry...

• The existing literature on the reliability of psychiatric diagnosis falls into two periods, the earlier reporting low reliability and the latter reporting much higher figures. The reasons for this trend are examined in the context of a discussion of the design of diagnostic reliability studies. The problems of research design and execution in studies of diagnostic reliability are reviewed, and statistical problems are examined. Solutions to many of these problems are suggested, including recom...

Abstract Results from 121 patients with major depressive disorder followed-up at 6 months with a new comprehensive follow-up schedule, the Longitudinal Interval Follow-Up Evaluation (LIFE) indicate that: 1. (1) Forty percent of patients had not recovered from the index episode 6 months after inclusion; 2. (2) Of those patients who recovered, 19% relapsed into another RDC affective episode by the time of the 6-months follow-up, and an additional 24% developed some subsequent affective symptoms by...

The authors present a 1-year prospective, naturalistic, longitudinal follow-up of 101 patients with the Research Diagnostic Criteria diagnosis of definite major depressive disorder. Seventy-four per cent of patients recover by 1 year. Of those who do recover, 36. per cent have subsequent Research Diagnostic Criteria affective episodes within the year. Episodes are of long duration for both the recovered and nonrecovered patients, being 30 weeks and at least 99 weeks, respectively. Certain common...

Abstract In this study we assess the reliability of rating past psychiatric symptoms and lifetime diagnoses in a currently ill population using the SADS and RDC. Five raters from different centers interviewed 25 subjects in a short-interval test-retest design. Subjects had a wide diversity of affective and non-affective diagnoses amd high levels of manifest psychopathology. Our results demonstrate that it is possible for raters from different research centers to reliably rate lifetime diagnoses ...

• It is important to determine the reliability of lifetime diagnosis in a nonpatient population, for this type of diagnostic data and this type of sample are used in many genetic, epidemiological, and nosological studies. We examined the reliability of lifetime diagnosis when the Schedule for Affective Disorders and Schizophrenia-Lifetime Version and Research Diagnostic Criteria were used to interview ill and well relatives of probands in the National Institute of Mental Health Collaborative Stu...
