The 16-Item quick inventory of depressive symptomatology (QIDS), clinician rating (QIDS-C), and self-report (QIDS-SR): a psychometric evaluation in patients with chronic major depression
The QIDS-SR(16) has highly acceptable psychometric properties, which supports the usefulness of this brief rating of depressive symptom severity in both clinical and research settings. Expand
Psychometric Properties of the
The Liebowitz Social Anxiety Scale (LSAS) is one of the most commonly used measures of social anxiety symptoms. To date, no study has examined its psychometric properties in a Latino sample. TheExpand
The Longitudinal Interval Follow-up Evaluation. A comprehensive method for assessing outcome in prospective longitudinal studies.
The Longitudinal Interval Follow-up Evaluation (LIFE) is an integrated system for assessing the longitudinal course of psychiatric disorders. It consists of a semistructured interview, an InstructionExpand
The long-term natural history of the weekly symptomatic status of bipolar I disorder.
Overall, the symptomatic structure is primarily depressive rather than manic, and subsyndromal and minor affective symptoms predominate, and the longitudinal weekly symptomatic course of BP-I is chronic. Expand
Conceptualization and rationale for consensus definitions of terms in major depressive disorder. Remission, recovery, relapse, and recurrence.
It is concluded that research on depressive illness would be well served by greater consistency in the definition change points in the course of illness, and proposes an internally consistent, empirically defined conceptual scheme for the terms remission, recovery, relapse, and recurrence. Expand
The epidemiology of major depressive episodes: results from the International Consortium of Psychiatric Epidemiology (ICPE) surveys
Community epidemiological surveys using the World Health Organization Composite International Diagnostic Interview administered face‐to‐face were carried out in 10 countries in North America, Latin America, Europe, and Asia. Expand
A comparison of nefazodone, the cognitive behavioral-analysis system of psychotherapy, and their combination for the treatment of chronic depression.
Although about half of patients with chronic forms of major depression have a response to short-term treatment with either nefazodone or a cognitive behavioral-analysis system of psychotherapy, the combination of the two is significantly more efficacious than either treatment alone. Expand
A prospective investigation of the natural history of the long-term weekly symptomatic status of bipolar II disorder.
The longitudinal symptomatic course of BP-II is chronic and is dominated by depressive rather than hypomanic or cycling/mixed symptoms, involving primarily symptoms of minor and subsyndromal severity. Expand
Influence of psychiatric comorbidity on recovery and recurrence in generalized anxiety disorder, social phobia, and panic disorder: a 12-year prospective study.
The anxiety disorders are depicted as insidious, with a chronic clinical course, low rates of recovery, and relatively high probabilities of recurrence, and the presence of particular comorbid psychiatric disorders significantly lowered the likelihood of recovery from anxiety disorders and increased thelihood of their recurrence. Expand
Multiple recurrences of major depressive disorder.
The number of lifetime episodes of major depression was significantly associated with the probability of recurrence, such that the risk of Recurrence increased by 16% with each successive recurrence and progressively decreased as the duration of recovery increased. Expand
