BACKGROUND Symptom severity as a moderator of treatment response has been the subject of debate over the past 20 years. Each of the meta- and mega-analyses examining the treatment significance of depression severity used the Hamilton Depression Rating Scale (HAMD), wholly, or in part, to define severity, though the cutoff used to define severe depression(More)
Social anxiety disorder (SAD), the 3rd most common psychiatric disorder in the United States, follows a chronic and unremitting course, often resulting in severe impairments in multiple areas of functioning. Despite a typical age of onset in early adolescence, the disorder is rarely recognized and treated in adolescent populations. Given its early age of(More)
Despite the demonstrated efficacy of cognitive-behavior therapy (CBT) for social anxiety disorder (SAD), many individuals do not respond to treatment or demonstrate residual symptoms and impairment posttreatment. Preliminary evidence indicates that acceptance-based approaches (e.g., acceptance and commitment therapy; ACT) can be helpful for a variety of(More)
The diagnosis of bipolar disorder has received increasing attention during the past decade. Several research reports have suggested that bipolar disorder is under-recognized, and that many patients, particularly those with major depressive disorder, have, in fact, bipolar disorder. More recently, some reports have suggested that bipolar disorder is also(More)
There are 227 possible ways to meet the symptom criteria for major depressive disorder (MDD). However, symptom occurrence is not random, and some symptoms co-occur significantly beyond chance. This raises the questions of whether all of the theoretically possible different ways of meeting the MDD criteria actually occur in patients, and whether some(More)
BACKGROUND To acknowledge the clinical significance of manic features in depressed patients, DSM-5 included criteria for a mixed features specifier for major depressive disorder (MDD). In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project we modified our previously published depression scale to(More)
OBJECTIVES The negative impact of bipolar disorder on occupational functioning is well established. However, few studies have examined the persistence of unemployment, and no studies have examined the association between diagnostic comorbidity and sustained unemployment. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment(More)
OBJECTIVE In the draft proposal for DSM-5, the Work Group for Personality and Personality Disorders recommended that dimensional ratings of personality disorders replace DSM-IV's categorical approach toward classification. If a dimensional rating of personality disorder pathology is to be adopted, then the clinical significance of minimal levels of(More)
OBJECTIVE Bipolar disorder and borderline personality disorder share some clinical features and have similar correlates. It is, therefore, not surprising that differential diagnosis is sometimes difficult. The Mood Disorder Questionnaire (MDQ) is the most widely used screening scale for bipolar disorder. Prior studies found a high false-positive rate on the(More)
Increasingly, emphasis is being placed on measurement-based care to improve the quality of treatment. Although much of the focus has been on depression, measurement-based care may be particularly applicable to social anxiety disorder (SAD) given its high prevalence, high comorbidity with other disorders, and association with significant functional(More)
