Simplifying profiles of comorbidity in bipolar disorder.

Background: Comorbid psychiatric symptoms in bipolar disorder (BD) predict poorer course of illness and treatment outcome. The sheer number of comorbid symptoms has thwarted developing treatments to address these comorbid concerns. The goal of this study was to develop a more parsimonious approach to understanding clusters of comorbid symptoms within BD.

Differentiating risk for mania and borderline personality disorder: The nature of goal regulation and impulsivity.

Researchers and clinicians have long noted the overlap among features and high comorbidity of bipolar disorder and borderline personality disorder. The shared features of impulsivity and labile mood in both disorders make them challenging to distinguish. We tested the hypothesis that variables related to goal dysregulation would be uniquely related to risk for mania, while emotion-relevant impulsivity would be related to risk for both disorders.

Epidemiology and course of unipolar mania: results from the national epidemiologic survey on alcohol and related conditions (NESARC).

Background: Unipolar mania (UM), in which only manic episodes occur during the course of illness, may be an important clinical manifestation of bipolar disorder that is under-recognized and understudied. The aim of this study is, for the first time, to examine the prevalence of UM and its clinical characteristics in the community.

Methods: Among a total of 1,411 subjects with bipolar I disorder, we evaluated the prevalence of UM using three different criteria proposed in previous studies.

Mindfulness-based cognitive therapy for bipolar disorder: effects on cognitive functioning.

Bipolar disorder is associated with impairments in cognition, including difficulties in executive functioning, even when patients are euthymic (neither depressed nor manic). The purpose of this study was to assess changes in self-reported cognitive functioning in patients with bipolar disorder who participated in an open pilot trial of mindfulness-based cognitive therapy (MBCT). Following MBCT, patients reported significant improvements in executive functioning, memory, and ability to initiate and complete tasks, as measured by the Behavior Rating Inventory of Executive Function (BRIEF) and the Frontal Systems Behavior Scale (FrSBe).

Mindfulness-based cognitive therapy for nonremitted patients with bipolar disorder.

Introduction: Bipolar disorder is characterized by recurrent episodes of depression and/or mania along with interepisodic mood symptoms that interfere with psychosocial functioning. Despite periods of symptomatic recovery, many individuals with bipolar disorder continue to experience substantial residual mood symptoms that often lead to the recurrence of mood episodes.

Aims: This study explored whether a new mindfulness-based cognitive therapy (MBCT) for bipolar disorder would increase mindfulness, reduce residual mood symptoms, and increase emotion-regulation abilities, psychological well-being, positive affect, and psychosocial functioning.

Positive affect regulation in anxiety disorders.

Although individual differences exist in how people respond to positive affect (PA), little research addresses PA regulation in people with anxiety disorders. The goal of this study was to provide information about responses to PA in people with symptoms of social phobia, generalized anxiety disorder, panic disorder, agoraphobia, and obsessive-compulsive disorder. The tendency to dampen PA and the ability to savor PA were examined in an undergraduate sample.

Elevated expectancies among persons diagnosed with bipolar disorder.

Objective: Students at risk for bipolar disorder endorse highly ambitious goals. This study examined expectations for the future among people with actual bipolar disorder, versus people with no history of mood disorder and persons with history of unipolar depression.

Methods: One hundred and three students were assessed for Axis I disorders and completed a measure of expected life outcomes.

An acceptance-based psychoeducation intervention to reduce expressed emotion in relatives of bipolar patients.

Expressed emotion (EE) is a robust predictor of outcome in bipolar disorder. Despite decades of research, interventions to reduce EE levels have had only modest effects. This study used an expanded model of EE to develop an intervention.

Cognitive responses to failure and success relate uniquely to bipolar depression versus mania.

This project examined cognitive responses to failure and success and their association with depression and mania within bipolar disorder. Many cognitive variables that are associated with unipolar depression have been found to be involved in bipolar disorder, more specifically bipolar depression. This research was the first to examine tendencies to hold high standards, engage in self-criticism, and generalize from failure to an overall sense of self-worth.
