Abstract
OBJECTIVES Bipolar disorder (BD) is associated with elevated reward sensitivity and persistent positive affect, yet the neural mechanisms underlying these patterns are not well understood. In the present study, we examined putative disruptions in communication within a well-known cortico-limbic reward circuit during reward processing as a potential contributing mechanism to these symptoms. METHODS The present investigation employed a within- and between-subjects design utilizing a monetary and social incentive delay task among adults with bipolar disorder type I (BD; N = 24) and a healthy non-psychiatric control group (HC; N = 25) during functional magnetic resonance imaging (fMRI). Participants in the BD group were remitted at the time of testing. RESULTS Functional connectivity analyses revealed increased connectivity between the ventral striatum (VS) seed region and orbitofrontal cortex (OFC) as well as the amygdala during processing of reward receipt in the BD group. After omission of expected rewards, the BD group showed decreased functional connectivity between the VS and a medial frontopolar cortex (mFPC) region associated with consideration of behavioral alternatives. Follow-up analyses within the BD group showed that increased VS-OFC connectivity after reward receipt, and decreased VS-mFPC connected after reward omission, were associated with higher levels of subthreshold mania symptoms. CONCLUSIONS Results point toward potential mechanisms implicated in elevated reward sensitivity in BD. Enhanced VS-OFC connectivity after reward receipt may be involved in elevated valuation of rewards whereas blunted VS-mFPC connectivity after reward omission may reflect a failure to consider behavioral alternatives to reward pursuit.

Abstract
We examined dynamical patterns in the course of bipolar depression. We interviewed 55 individuals with bipolar I disorder using Modified Hamilton Rating Scale for Depression (MHRSD) for at least 20 months. Using a recently developed methodology, we categorized the level of instability and the nature of attractor patterns for each individual. Instability was related to the lifetime severity of depression as well as suicidality during the follow-up period. Individuals varied from 0 to 2 in the number of attractors. Relatively few individuals displayed only one attractor that fell within a depressive range; the most common patterns were instability and two attractors. Limitations and implications of these results are discussed.

Abstract
Life stress is a major predictor of the course of bipolar disorder. Few studies have used laboratory paradigms to examine stress reactivity in bipolar disorder, and none have assessed autonomic reactivity to laboratory stressors. In the present investigation we sought to address this gap in the literature. Participants, 27 diagnosed with bipolar I disorder and 24 controls with no history of mood disorder, were asked to complete a complex working memory task presented as "a test of general intelligence." Self-reported emotions were assessed at baseline and after participants were given task instructions; autonomic physiology was assessed at baseline and continuously during the stressor task. Compared to controls, individuals with bipolar disorder reported greater increases in pretask anxiety from baseline and showed greater cardiovascular threat reactivity during the task. Group differences in cardiovascular threat reactivity were significantly correlated with comorbid anxiety in the bipolar group. Our results suggest that a multimethod approach to assessing stress reactivity-including the use of physiological parameters that differentiate between maladaptive and adaptive profiles of stress responding-can yield valuable information regarding stress sensitivity and its associations with negative affectivity in bipolar disorder.

Abstract
Extensive research supports the role of striatal dopamine in pursuing and responding to reward, and that eye-blink rate is a valid indicator of striatal dopamine. This study tested whether phasic changes in blink rate could provide an index of reward pursuit. This hypothesis was tested in people with bipolar I disorder (BD; a population with aberrations in reward responsivity), and in those without BD. Thirty-one adults with BD and 28 control participants completed a laboratory task involving effort towards monetary reward. Blink rate was recorded using eye-tracking at baseline, reward anticipation, and post-reward. Those in the BD group completed self-report measures relating to reward and ambition. Results showed that across all participants, blink rates increased from reward anticipation to post-reward. In the BD group, reward-relevant measures were strongly correlated with variation in blink rate. These findings provide validation for phasic changes in blink rate as an index of reward response.

Abstract
Bipolar disorder is fundamentally a disorder of emotion regulation, and associated with explicit processing biases for socially relevant emotional information in human faces. Less is known, however, about whether implicit processing of this type of emotional information directly influences social perception. We thus investigated group-related differences in the influence of unconscious emotional processing on conscious person perception judgments using a continuous flash suppression task among 22 individuals with remitted bipolar I disorder (BD; AgeM=30.82, AgeSD=7.04; 68.2% female) compared with 22 healthy adults (CTL; AgeM=20.86, AgeSD=9.91; 72.2% female). Across both groups, participants rated neutral faces as more trustworthy, warm, and competent when paired with unseen happy faces as compared to unseen angry and neutral faces; participants rated neutral faces as less trustworthy, warm, and competent when paired with unseen angry as compared to neutral faces. These findings suggest that emotion-related disturbances are not explained by early automatic processing stages, and that activity in the dorsal visual stream underlying implicit emotion processing is intact in bipolar disorder. Implications for understanding the etiology of emotion disturbance in BD are discussed.

Abstract
BACKGROUND The concept of the "efficacy-effectiveness gap" (EEG) has started to challenge confidence in decisions made for drugs when based on randomized controlled trials alone. Launched by the Innovative Medicines Initiative, the GetReal project aims to improve understanding of how to reconcile evidence to support efficacy and effectiveness and at proposing operational solutions. OBJECTIVES The objectives of the present narrative review were 1) to understand the historical background in which the concept of the EEG has emerged and 2) to describe the conceptualization of EEG. METHODS A focused literature review was conducted across the gray literature and articles published in English reporting insights on the EEG concept. The identification of different "paradigms" was performed by simple inductive analysis of the documents' content. RESULTS The literature on the EEG falls into three major paradigms, in which EEG is related to 1) real-life characteristics of the health care system; 2) the method used to measure the drug's effect; and 3) a complex interaction between the drug's biological effect and contextual factors. CONCLUSIONS The third paradigm provides an opportunity to look beyond any dichotomy between "standardized" versus "real-life" characteristics of the health care system and study designs. Namely, future research will determine whether the identification of these contextual factors can help to best design randomized controlled trials that provide better estimates of drugs' effectiveness.

Emotion-relevant impulsivity predicts sustained anger and aggression after remission in bipolar I disorder. J Affect Disord 2016; 189:169-75.

Abstract
Recent evidence suggests that anger and aggression are of concern even during remission for persons with bipolar I disorder, although there is substantial variability in the degree of anger and aggression across individuals. Little research is available to examine psychological models of anger and aggression for those with remitted bipolar disorder, and that was the goal of this study. Participants were 58 persons diagnosed with bipolar I disorder using the Structured Clinical Interview for DSM-IV, who were followed with monthly symptom severity interviews until they achieved remission, and then assessed using the Aggression-Short Form. We examined traditional predictors of clinical parameters and trauma exposure, and then considered three trait domains that have been shown to be elevated in bipolar disorder and have also been linked to aggression outside of bipolar disorder: emotion-relevant impulsivity, approach motivation, and dominance-related constructs. Emotion-relevant impulsivity was related to anger, hostility, verbal aggression, and physical aggression, even after controlling for clinical variables. Findings extend the importance of emotion-relevant impulsivity to another important clinical outcome and suggest the promise of using psychological models to understand the factors driving aggression and anger problems that persist into remission among persons with bipolar disorder.

Abstract
Disruptions in activity are core features of mood states in bipolar disorder (BD). This study sought to identify activity patterns that discriminate between mood states in BD. Locomotor activity was collected using actigraphy for six weeks in participants with inter-episode BD type I (n=37) or participants with no lifetime mood disorders (n=39). The 24-hour activity pattern of each participant-day was characterized and within-person differences in activity patterns were examined across mood states. Results show that among participants with BD, depressive days are distinguished from other mood states by an overall lower activity level, and a pattern of later activity onset, a midday elevation of activity, and low evening activity. No distinct within-person activity patterns were found for hypomanic/manic days. Since activity can be monitored non-invasively for extended time periods, activity pattern identification may be leveraged to detect mood states in BD, thereby providing more immediate delivery of care.

Abstract
Despite the centrality of emotion disturbance in neurobiological models of bipolar disorder, the behavioral literature has not yet clearly identified the most central aspects of emotion disturbance in bipolar disorder. Toward this aim, we gathered a battery of emotion-related measures in 67 persons diagnosed with bipolar I disorder as assessed with the SCID and a well-matched control group of 58 persons without a history of mood disorders. Those with bipolar disorder were interviewed monthly until they achieved remission, and then tested on emotion measures. A subset of 36 participants with bipolar disorder completed symptom severity interviews at 12-month follow-up. Factor analyses indicated 4 emotion factor scores: Negative Emotion, Positive Emotion, Reappraisal, and Suppression. Bivariate analyses suggested that bipolar disorder was tied to a host of emotion disturbances, but multivariate analyses suggested that bipolar disorder was particularly tied to elevations of Negative Emotion. High Negative Emotion, low Positive Emotion, and high Suppression were conjointly related to lower functioning. Reappraisal predicted declines in depression over time for those with bipolar disorder. Findings highlight the importance of considering the overall profile of emotion disturbance in bipolar disorder. Emotion and emotion regulation appear central to a broad range of outcomes in bipolar disorder.

Abstract
Bipolar disorder (BD) is associated with increased reactivity to rewards and heightened positive affectivity. It is less clear to what extent this heightened reward sensitivity is evident across contexts and what the associated neural mechanisms might be. The present investigation used both a monetary and social incentive delay task among adults with remitted BD Type I (n = 24) and a healthy nonpsychiatric control group (HC; n = 25) using fMRI. Both whole-brain and region-of-interest analyses revealed elevated reactivity to reward receipt in the striatum, a region implicated in incentive sensitivity, in the BD group. Post hoc analyses revealed that greater striatal reactivity to reward receipt, across monetary and social reward tasks, predicted decreased self-reported positive affect when anticipating subsequent rewards in the HC but not in the BD group. Results point toward elevated striatal reactivity to reward receipt as a potential neural mechanism of persistent reward pursuit in BD.

Abstract
BACKGROUND Bipolar disorder type I (BD-I) is associated with emotion dysregulation. However, experimentally controlled studies of emotion regulation (ER), particularly those examining the brain correlates of the putative deficits, are scarce and their results inconsistent. METHOD Nineteen euthymic BD-I patients and 17 healthy controls (HC) underwent functional magnetic resonance imaging while performing a visual ER 2 × 2 factorial task, with instruction (Look or Decrease) and valence (Negative or Neutral) as within-subject factors. Emotional ratings were collected after each picture presentation to assess regulation success. RESULTS BD-I patients were successful at downregulating their emotions, although to a lesser degree than HC. Both groups engaged brain regions previously implicated in ER; however, unlike HC, patients engaged some of those regions, particularly the ventrolateral prefrontal cortex (VLPFC) in the Negative Look and Neutral Decrease conditions. Moreover, patients failed to show the reduced amygdala activation in the Negative Decrease condition observed in HC. CONCLUSION Our findings suggest that BD-I patients are able to downregulate their emotions when instructed to do so. However, they also appear to engage their ER network, particularly the VLPFC, even when not required to do so. These findings may help explain their often-reported difficulty in regulating emotions in everyday life despite their attempts to do so.

Abstract
Little is known about the nature of the relation between information-processing biases and affective traits in bipolar disorder. The present study was designed to investigate whether attentional biases are evident in persons diagnosed with bipolar disorder when they are in a positive mood state, and whether biases are related to indices of emotion regulation and to prior history of mood episodes. Ninety adults diagnosed with bipolar I disorder and 81 controls with no lifetime mood disorder underwent a positive mood induction and then completed an emotion face dot-probe task; participants in the bipolar disorder group also completed a self-report measure of responses to positive affect. Attentional bias was not related to a diagnosis of bipolar disorder or to symptom severity. Consistent with hypotheses, analyses within the bipolar group indicated that greater dampening of positive affect related to significantly less attention paid to the positively valenced faces. Discussion focuses on the potential role of affective traits in shaping attentional bias in bipolar disorder.

Abstract
BACKGROUND Mood disorders represent the most expensive mental disorders for employer-based commercial health plans. Collaborative care models are effective in treating chronic physical and mental illnesses at little to no net healthcare cost, but to date have primarily been implemented by larger healthcare organizations in facility-based models. The majority of practices providing commercially insured care are far too small to implement such models. Health plan-level collaborative care treatment can address this unmet need. The goal of this study is to implement at the national commercial health plan level a collaborative care model to improve outcomes for persons with mood disorders. METHODS/DESIGN A randomized controlled trial of a collaborative care model versus usual care will be conducted among beneficiaries of a large national health plan from across the country seen by primary care or behavioral health practices. At discharge 344 patients identified by health plan claims as hospitalized for unipolar depression or bipolar disorder will be randomized to receive collaborative care (patient phone-based self-management support, care management, and guideline dissemination to practices delivered by a plan-level care manager) or usual care from their provider. Primary outcomes are changes in mood symptoms and mental health-related quality of life at 12 months. Secondary outcomes include rehospitalization, receipt of guideline-concordant care, and work productivity. DISCUSSION This study will determine whether a collaborative care model for mood disorders delivered at the national health plan level improves outcomes compared to usual care, and will inform a business case for collaborative care models for these settings that can reach patients wherever they receive treatment.

Abstract
OBJECTIVE To evaluate the relative role of psychopathology in the relationship between physical activity and sleep, the present study investigated the day-to-day relationship between physical activity and sleep in individuals without a psychiatric disorder and individuals with bipolar disorder using a longitudinal, naturalistic design. METHOD Participants in two groups-a healthy group with no psychiatric illness (N=36) and an inter-episode bipolar disorder group (N=32)- were studied over a two-month period. Physical health was assessed by the SF-36. Daily subjective and objective measures of physical activity and sleep were collected. A total of 6,670 physical activity measurements and 6,548 sleep measurements were logged. RESULTS The bipolar disorder group exhibited poorer physical health on the SF-36 and more sleep disturbance relative to the healthy group. No group differences were found in physical activity, nor in models examining the relationship between physical activity and sleep. Hierarchical linear models indicated that for every standard deviation increase in sleep disturbance (i.e., increased total wake time), there was a three percent decrease in subsequent day physical activity, in both the healthy and bipolar groups. Increased physical activity was associated with improved sleep for participants who reported greater average sleep disturbance. CONCLUSIONS The results for all participants in the study suggest that reduced physical activity and sleep difficulties may be mutually maintaining processes, particularly for individuals who suffer from poor sleep. Findings also raise the potential importance of targeting physical activity and sleep concurrently in interventions aimed at improving physical and mental health.

Abstract
OBJECTIVE Bipolar disorder has been associated with elevated impulsivity - a complex construct subsuming multiple facets. We aimed to compare specific facets of impulsivity in bipolar disorder, including those related to key psychological correlates of the illness: reward sensitivity and strong emotion. METHOD Ninety-one individuals diagnosed with bipolar I disorder (inter-episode period) and 80 controls completed several well-validated impulsivity measures, including those relevant to reward (Fun-seeking subscale of the Behavioral Activation System scale) and emotion (Positive Urgency and Negative Urgency scales). RESULTS Bipolar participants reported higher impulsivity scores than did controls on all of the impulsivity measures, except the Fun-seeking subscale of the Behavioral Activation System scale. Positive Urgency - a measure assessing the tendency to act impulsively when experiencing strong positive emotion - yielded the largest group differences: F(1,170) = 78.69, P < 0.001, partial η(2) = 0.316. Positive Urgency was also associated with poorer psychosocial functioning in the bipolar group: ΔR(2) = 0.24, b = -0.45, P < 0.001. CONCLUSION Individuals with bipolar I disorder appear to be at particular risk of behaving impulsively when experiencing strong positive emotions. Findings provide an important first step toward developing a more refined understanding of impulsivity in bipolar disorder with the potential to inform targeted interventions.

Abstract
OBJECTIVE The authors compared fidelity to bipolar disorder treatment at community practices that received a standard or enhanced version of a novel implementation intervention called Replicating Effective Programs (REP). METHODS Five community practices in Michigan and Colorado were assigned at random to receive enhanced (N=3) or standard (N=2) REP to help implement Life Goals Collaborative Care (LGCC), a psychosocial intervention consisting of four self-management support group sessions, ongoing care management contacts by phone, and dissemination of guidelines to providers. Standard REP includes an intervention package consisting of an outline, a treatment manual and implementation guide, a standard training program, and as-needed technical assistance. Enhanced REP added customization of the treatment manual and ongoing, proactive technical assistance from internal and external facilitators. Multiple and logistic regression analyses determined the impact of enhanced versus standard REP on patient-level fidelity. RESULTS The participants (N=384) had a mean age of 42 years; 67% were women, and 30% were nonwhite. Participants attended an average of three group sessions and had an average of four care management contacts. After adjustment for patient factors, enhanced REP was associated with 2.6 (p<.001) times more total sessions and contacts than standard REP, which was driven by 2.5 (p<.01) times more care management contacts. Women and participants with a history of homelessness had fewer total sessions and contacts. CONCLUSIONS Enhanced REP was associated with improved LGCC fidelity, primarily for care management contacts. Additional customization of interventions such as LGCC may be needed to ensure adequate treatment fidelity for vulnerable populations.

Abstract
BACKGROUND Exposure to life stress is known to adversely impact the course of bipolar disorder. Few studies have disentangled the effects of multiple types of stressors on the longitudinal course of bipolar I disorder. This study examines whether severity of chronic stressors and exposure to trauma are prospectively associated with course of illness among bipolar patients. METHOD One hundred and thirty-one participants diagnosed with bipolar I disorder were recruited through treatment centers, support groups and community advertisements. Severity of chronic stressors and exposure to trauma were assessed at study entry with in-person interviews using the Bedford College Life Event and Difficulty Schedule (LEDS). Course of illness was assessed by monthly interviews conducted over the course of 24 months (over 3000 assessments). RESULTS Trauma exposure was related to more severe interpersonal chronic stressors. Multiple regression models provided evidence that severity of overall chronic stressors predicted depressive but not manic symptoms, accounting for 7.5% of explained variance. CONCLUSIONS Overall chronic stressors seem to be an important determinant of depressive symptoms within bipolar disorder, highlighting the importance of studying multiple forms of life stress.

Abstract
BACKGROUND The Iowa Gambling Task (IGT) has been recommended as an index of reward sensitivity, which is elevated in bipolar disorder. We conducted a meta-analysis of IGT performance in euthymic bipolar I disorder compared with control participants. Findings indicated that people with bipolar disorder make more risky choices than control participants, though the effect is small (g=0.35). It is not clear which of the many processes involved in IGT performance are involved in producing the observed group difference. METHODS Fifty-five euthymic people with bipolar disorder and 39 control participants completed the IGT. The Expectancy Valence Model was used to examine differences in IGT. We also examined whether variation in IGT performance within the bipolar group was related to current mood, illness course, impulsivity, or demographics. RESULTS Bipolar and control groups did not differ on the total number of risky choices, rate of learning, or any of the parameters of the Expectancy Valence Model. IGT performance in bipolar disorder was not related to any of the examined individual differences. LIMITATIONS It is possible that there are group differences that are too small to detect at our sample size or that are not amenable to study via the Expectancy Valence Model. CONCLUSIONS We were unable to identify group differences on the IGT or correlates of IGT performance within bipolar disorder. Though the IGT may serve as a useful model for decision-making, its structure may make it unsuitable for behavioral assessment of reward sensitivity independent of punishment sensitivity.

Abstract
BACKGROUND Researchers have linked bipolar disorder to elevations in reward sensitivity and positive affect. Little is known, however, about how people with bipolar disorder respond to rewards and positive affect and how these tendencies relate to functioning or quality of life. METHODS Persons diagnosed with bipolar I disorder and matched controls completed the Responses to Positive Affect (RPA) measure and the Brief Quality of Life in Bipolar Disorder scale. Bipolar participants also completed the Reward Responses Inventory, which we designed to assess the extent to which participants avoid rewarding activities to prevent mania. A subsample of participants with bipolar disorder completed a positive mood induction procedure to examine the validity of the Response to Positive Affect scale. RESULTS The majority of bipolar participants reported avoiding at least one rewarding activity as a means of preventing mania. In addition, people with bipolar I disorder reported more dampening responses to positive affect than did control participants. Dampening positive emotions was related to lower quality of life. LIMITATIONS This study does not address whether responses to affect and reward are related to the longitudinal course of symptoms. CONCLUSIONS These findings suggest that people with bipolar I disorder seem to be aware of the potential of goal achievements to trigger mania, and many people with bipolar disorder seem to take steps to avoid positive emotion and reward.

Abstract
OBJECTIVE The objective of this study was to evaluate demographic, psychosocial and clinical predictors of mood recurrences in bipolar disorder (BD) euthymic outpatients followed-up for 12 months in a naturalistic setting. METHODS The study included 595 consecutive BD patients, diagnosed according to DSM-IV-TR criteria, in clinical remission at baseline. Quarterly assessments were scheduled. Clinical evaluation as well as mood and functioning psychometric evaluations were performed. We applied logistic regression analysis to determine predictors of presenting an affective recurrence, and Cox regression analysis to examine the association between individual predictors and time to affective recurrence. RESULTS Of the 593 patients finally included (60% women, 84.5% BD I), 141 (23.78%) had at least a recurrence during the 12 months follow-up. Time until 25% of the patients experienced a recurrence was 12 months (95% CI: 9.14-undetermined). In multivariate analysis, factors significantly related to relapse were living setting (p=0.002) and total number of previous episodes (p=0.01). Residents in mixed urban/rural catchment areas had 57% more risk than dwellers of cities with more than 100,000 people, and a higher number of previous episodes also increased the relapse risk. A shorter time to relapse was related to job status (p=0.004) and to living setting (p=0.002). CONCLUSION In our sample, living in environments of less than 100,000 inhabitants and having more previous affective episodes were related to an increased relapse risk in BD, and job status and living setting were related to a shorter time to relapse. LIMITATIONS No specific contemporary practice guidelines were used. Drug treatment and plasma levels, although measured, were not registered.

Abstract
OBJECTIVES This study focused on social support and social strain and their cross-sectional associations with instabilities in sleep and social rhythms in inter-episode bipolar disorder (BD). METHODS Thirty-five adults diagnosed with inter-episode BD type I and 38 healthy controls completed measures of perceived social support and social strain. Group differences in support and strain were examined. Within the BD group, instabilities in sleep and social rhythms were assessed with 28 days of daily diary and actigraphy. Correlation and regression analyses were used to examine cross-sectional and prospective associations between social support, social strain, instabilities in sleep and social rhythms, and mood symptoms. RESULTS The BD group reported lower social support and higher social strain than the control group. Additionally, social strain was positively correlated with manic and depressive symptoms in the BD group. Furthermore, there was a cross-sectional association between social support and more stable sleep on actigraphy in the BD group, although social support did not predict future sleep instability. CONCLUSIONS These results indicate that inter-episode BD is associated with deficient social support and elevated social strain compared to controls, and that this may be due to persistent inter-episode mood symptoms. Social strain may be particularly important given its association with manic and depressive symptoms. The results also raise the possibility that sleep instability is related to poor social support in BD.

Abstract
Disturbances in sleep and affect are prominent features of bipolar disorder, even during interepisode periods. Few longitudinal studies have prospectively examined the relationship between naturally occurring sleep and affect, and no studies to date have done so during interepisode periods of bipolar disorder and using the entire set of "gold standard" sleep parameters. Participants diagnosed with bipolar I disorder who were interepisode (n = 32) and healthy controls (n = 36) completed diagnostic and symptom severity interviews, and a daily sleep and affect diary, as well as an actigraphy sleep assessment, for eight weeks (M = 54 days, ± 8 days). Mutual information analysis was used to assess the degree of statistical dependence, or coupling, between time series data of sleep and affect. As measured by actigraphy, longer sleep onset latency was coupled with higher negative affect more strongly in the bipolar group than in the control group. As measured by sleep diary, longer wakefulness after sleep onset and lower sleep efficiency were coupled with higher negative affect significantly more strongly in the bipolar group than in the control group. By contrast, there were no significant differences between groups in the degree of coupling between any measures of sleep and positive affect. Findings support the coupling of sleep disturbance and negative affect during interepisode bipolar disorder. Ongoing monitoring of sleep-affect coupling may provide an important target for intervention in bipolar disorder.

Abstract
OBJECTIVES To conduct a systematic review to address the following key questions: (1) what interventions have been successful in improving access for veterans with reduced health care access? (2) Have interventions that have improved health care access led to improvements in process and clinical outcomes? DATA SOURCES OVID MEDLINE, CINAHL, PsychINFO. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS English language articles published in peer-reviewed journals from 1990 to June 2010. All interventions designed to improve access to health care for US veterans that reported the impact of the intervention on perceived (e.g., satisfaction with access) or objective (e.g., travel time, wait time) access were included. APPRAISAL AND SYNTHESIS METHODS: Investigators abstracted data on study design, study quality, intervention, and impact of the intervention on access, process outcomes, and clinical outcomes. RESULTS Nineteen articles (16 unique studies) met the inclusion criteria. While there were a small number of studies in support of any one intervention, all showed a positive impact on either perceived or objective measures of access. Implementation of Community Based Outpatient Clinics (n = 5 articles), use of Telemedicine (n = 5 articles), and Primary Care Mental Health Integration (n = 6 articles) improved access. All 16 unique studies reported process outcomes, most often satisfaction with care and utilization. Four studies reported clinical outcomes; three found no differences. LIMITATIONS Included studies were largely of poor to fair methodological quality. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS Interventions can improve access to health care for veterans. Increased access was consistently linked to increased primary care utilization. There was a lack of data regarding the link between access and clinical outcomes; however, the limited data suggest that increased access may not improve clinical outcomes. Future research should focus on the quality and appropriateness of care and clinical outcomes.

Abstract
BACKGROUND Few studies have examined differences in emotional responding among distinct types of positive stimuli. This is important to understand both for individuals characterized by extreme positive mood (i.e., bipolar disorder) and healthy adults. METHODS Using a multi-method within-subjects design, the current study examined physiological, behavioral, and self-reported responses to normative (film) and idiographic (memory) happy stimuli in bipolar (BD; n=25) and healthy control groups (CTL; n=23). RESULTS For both groups, the happy films were associated with greater self-reported and behavioral displays of positive emotion compared to the happy memory. Furthermore, the BD group displayed greater cardiac vagal tone - a putative marker of positive emotion - across both the film and memory. CONCLUSION Normative stimuli were more potent elicitors of positive emotion compared to idiographic stimuli. The study provided further evidence for cardiac vagal tone as a potential biomarker of extreme positive emotion in BD.

Abstract
Potential mechanisms to explain the relationship between Expressed Emotion (EE) and poor outcome within bipolar disorder are poorly understood. One possibility is that people with bipolar disorder have difficulty regulating their affect in response to criticism. The present study examined whether participants with bipolar disorder were more affectively dysregulated than control participants when presented with a criticism by a confederate. There was a trend for people with bipolar disorder to react more negatively to the criticism, but there was also evidence that they recovered as quickly as controls. Exploratory analyses found that female gender, the perception of the criticism as more negative, being disabled, and having fewer positive relationships predicted greater reactivity to criticism among people with bipolar disorder.

Abstract
Recent evidence suggests that reflective (i.e., distanced-why), as compared to ruminative (i.e., immersed-why), processing of negative memories is associated with reductions in negative affect. The present study extended this line of work by examining the effect of these two processing conditions on positive memories among persons with bipolar disorder (BD; n = 27) and a healthy control group (CT; n = 27). After a resting baseline period, participants were instructed to recall a happy autobiographical memory. Using a within-subjects design, participants were asked to process the happy memory in two different experimental conditions (reflective, ruminative) while their experiential, behavioral, and autonomic responses were measured. Consistent with hypotheses, reflective processing was associated with lower self-reported positive affect, positive thoughts, and heart rate compared to ruminative processing for all participants. When current symptoms were controlled for, BD participants reported greater positive affect across both conditions relative to CT participants. Prospective studies are needed to test the extent to which processing of positive emotion contributes to the course of symptoms in bipolar disorder.

Abstract
PURPOSE Studies to improve patient access to care have generally involved office based primary care practices or highly managed systems. Surgical practices differ in their referral nature, the common need for imaging at the first appointment and the need to schedule subsequent surgical procedures. We determined whether new patient access to care can be improved in a surgical practice. MATERIALS AND METHODS To reduce new patient appointment wait times to a goal of 5 working days (1 week), a 12-week transition period into a new scheduling approach was designed. At the next clinic with open slots (9 weeks away) 10% of the appointments were held open until the week before for new patient visits. For each of the following 4 weeks 10% additional appointments were held open each week until 50% were being reserved. These slots were not available until 1 week before the clinic date and then were only open for new patients calling to make an appointment. RESULTS Appointment delay times improved significantly and this improvement has been durable for 2 years. Interestingly our no show rate did not change. CONCLUSIONS A surgical office with long new patient appointment wait times can improve access to clinic consultations by implementing this system.

Abstract
BACKGROUND The effectiveness of bipolar collaborative chronic care models (B-CCMs) among those with co-occurring substance use, psychiatric, and/or medical conditions has not specifically been assessed. We assessed whether B-CCM effects are equivalent comparing those with and without co-occurring conditions. METHODS We reanalyzed data from the VA Cooperative Study #430 (n=290), an 11-site randomized controlled trial of the B-CCM compared to usual care. Moderators included common co-occurring conditions observed in patients with bipolar disorder, including substance use disorders (SUD), anxiety, psychosis; medical comorbidities (total number), and cardiovascular disease-related conditions (CVD). Mixed-effects regression models were used to determine interactive effects between moderators and 3-year primary outcomes. RESULTS Treatment effects were comparable for those with and without co-occurring substance use and psychiatric conditions, although possibly less effective in improving physical quality of life in those with CVD-related conditions (Beta=-6.11;p=0.04). LIMITATIONS Limitations included multiple comparisons and underpowered analyses of moderator effects. CONCLUSIONS B-CCM effects were comparable in patients with co-occurring conditions, indicating that the intervention may be generally applied. Specific attention to physical quality of life in those with CVD maybe warranted.

To date, few prospective studies of life events and bipolar disorder are available, and even fewer have separately examined the role of life events in depression and mania. The goal of this study was to prospectively examine the role of negative and goal-attainment life events as predictors of the course of bipolar disorder. One hundred twenty-five individuals with bipolar I disorder were interviewed monthly for an average of 27 months. Negative and goal-attainment life events were assessed with the Life Events and Difficulties Schedule. Changes in symptoms were evaluated using the Modified Hamilton Rating Scale for Depression and the Bech-Rafaelsen Mania Scale. The clearest results were obtained for goal-attainment life events, which predicted increases in manic symptoms over time. Negative life events predicted increases in depressive symptoms within regression models but were not predictive within multilevel modeling of changes in depressive symptoms. Given different patterns for goal attainment and negative life events, it appears important to consider specific forms of life events in models of bipolar disorder.

Abstract
Despite the success of pharmacotherapy in the management of bipolar disorder, as many as one-half of those in treatment discontinue their medication over time. Currently, no self-report measure is available that predicts treatment engagement in bipolar disorder. The goal of the current study was to develop a measure of awareness of symptoms and attitudes toward treatment among those with bipolar disorder. Sixty-six participants diagnosed with bipolar I disorder on the SCID completed the Treatment Attitudes Questionnaire (TAQ) and were then followed for up to 2 years to assess symptom levels. Medication data were available for 37 participants. Analyses of the TAQ were conducted to examine reliability, predictors of subscales, and how well scores predicted medication and symptom levels over time. Results indicate that previous episodes of depression, but not episodes of mania, correlated with increased scores on the Insight and the Enjoyment of Mania subscales. Scores on the Nonbiological Attributions subscale predicted lower levels of lithium as well as increased depressive symptoms over time. Although the current study includes limited measurement of treatment engagement and a small sample size, this easily administered scale may help treatment planning for those with bipolar disorder.

Abstract
Psychiatric nurses are increasingly being involved in the provision of care for outpatients with bipolar disorder. The establishment of a body of knowledge for the nursing of these patients is vital for the development of integrated evidence-based treatment. The literature for the period January 1980 to January 2006 is reviewed. A sensitive literature search included not only the nursing care based on research results but also nursing care based on experiences acquired by practising nurses. The results show that formal research on the nursing of patients with a bipolar disorder is remarkably limited. Three quantitative studies were identified in five articles and six qualitative studies addressing a broad range of topics. The remainder of articles meeting the inclusion criteria contained mostly descriptive reports. An overview is presented of the nursing processes used during the euthymic stage of a bipolar disorder and during an acute episode of (hypo)mania. No specific nursing processes for acute episodes of bipolar depression are described in the literature. The results show hardly any evidence for the described nursing processes.

Abstract
OBJECTIVE Many patients report sleeping less than 6 h per night during episodes of depression and mania. This type of sleep deficit may also be a risk factor for subsequent mood episodes; however, the long-term impact of sleep deficit remains unclear. The current study is among few longitudinal studies to assess the prospective effect of sleep deficit on depression and mania. METHODS A subsample of 54 individuals from a longitudinal study of bipolar I disorder was selected. Participants entered the study during a mood episode. Baseline symptom data were collected at month 4 to allow for recovery from the initial episode, sleep was assessed at month 6, and follow-up symptom data were obtained during months 7-12. RESULTS Sleep deficit predicted depressive symptoms across the 6-month follow-up but not mania. CONCLUSIONS It is likely that the impact of sleep deficit on mania was probably missed because assessments covered a full month. Monitoring sleep duration may help predict depression in bipolar disorder and provide an opportunity for targeting intervention.

Abstract
BACKGROUND In recent years, several controlled studies could show that psychoeducational interventions have been effective for relapse prevention in bipolar disorders. We therefore established a cognitive-psychoeducational group intervention with 14 sessions providing information about the illness, early warning signs, cognitive and behavioural strategies for stress management and social rhythm. Additionally we offered a group intervention for the patients' relatives. The objective of this study was to describe the outcome associated with our psychoeducational intervention in bipolar patients and their relatives. METHODS Sixty-two bipolar patients attended 14 sessions (à 90 min) of cognitive-psychoeducational group therapy. Patients' knowledge of bipolar disorder and their satisfaction with the treatment were assessed using self-developed questionnaires before and after the group intervention. Additionally, 49 relatives of bipolar patients received two psychoeducational workshops of 4 hours each. We assessed demographic variables, burden, high expressed emotion and depressive symptoms of the relatives before and after the two workshops and at 1-year follow-up. RESULTS Patients significantly improved their knowledge of bipolar disorder. They also have benefited from the discussions and the exchange of useful coping strategies. Burden and high expressed emotions showed no significant reductions at post-assessment, however they were significantly reduced at 1-year follow-up. Relatives also felt significantly better informed about the illness. CONCLUSIONS These findings show that psychoeducational interventions in bipolar patients and their relatives improve patients' and their relatives' knowledge of the illness and the burden of the disorder as well as high expressed emotions are reduced in relatives at 1-year follow-up.

Abstract
People with bipolar disorder are at high suicide risk. The literature suggests that suicidality is predicted by higher symptom severity and less use of pharmacological agents, but few studies have examined the joint contributions of these variables. The present study examines the conjoint contribution of symptom severity and pharmacological treatment to suicidal ideation and behavior among participants with bipolar disorder. The model was able to account for 53% of the variance in suicidality scores. Depression, mixed state, and hopelessness were significantly associated with suicidality. All other variables were nonsignificant once symptom severity had been controlled. Implications for future research are described.

Abstract
An emerging literature suggests that a collaborative care model, in which patients are active managers of their illness within a supportive social environment, is a beneficial approach for individuals with bipolar disorder. One aspect of treatment that is often suboptimal among individuals with bipolar disorder is treatment adherence. Establishing an ideal collaborative model may offer an opportunity to enhance treatment adherence among individuals with bipolar disorder. This paper presents results from a qualitative exploration of patients' attitudes towards the collaborative care model and how individuals with bipolar disorder perceive treatment adherence within the context of the collaborative care model. All participants were actively enrolled in outpatient treatment at a Community Mental Health Center and part of a larger study that evaluated the Life Goals Program, a manual-driven structured group psychotherapy for bipolar disorder that is based on the collaborative practice model. The Life Goals Program is designed to assist individuals to participate more effectively in the management of their bipolar illness and to improve their social and work-related problems. Individuals were queried regarding their opinions on the ingredients for an effective client-provider relationship. Quantitative data were collected on baseline treatment adherence as well. Individuals treated for bipolar disorder in a community mental health clinic identified 12 key elements that they felt were critical ingredients to a positive collaborative experience with their mental health care provider. The authors conceptualized these elements around 3 emerging themes: patient-centered qualities, provider-centered qualities, and interactional qualities. Individuals with bipolar disorder perceived the ideal collaborative model as one in which the individual has specific responsibilities such as coming to appointments and sharing information, whereas the provider likewise has specific responsibilities such as keeping abreast of current "state-of-the-arf" prescribing practices and being a good listener. Treatment adherence was identified as a self-managed responsibility within the larger context of the collaborative model. Individuals with bipolar disorder in this study placed substantial emphasis on the interactional component within the patient-provider relationship, particularly with respect to times when the individual may be more symptomatic and more impaired. It is important that clinicians and care providers gather information related to patients' perceptions of the patient-provider relationship when designing or evaluating services aimed at enhancing treatment adherence.

Abstract
Bipolar disorder is a chronic, debilitating psychiatric illness with serious ramifications for patients, their families, and society. Despite the availability of effective treatments, this disease often goes untreated due to medical, financial, legal/governmental, and cultural barriers. In this review we explore possible reasons for this problem. Misdiagnosis of bipolar disorders is a common medical barrier. One pathway to care for individuals with bipolar disorder is through referral from primary care, but primary care physicians generally have not received special training in the recognition and management of bipolar disorder. This often leads to diagnostic delays or errors, which prevents timely 'filtering' of patients into specialized care. Using data bases we explored these pathways. Legislation in the USA, such as the Emergency Medical Treatment and Active Labor Act (EMTALA), designed to ensure access to inpatient mental health care, has instead given hospitals financial incentives to limit inpatient mental health care capacities. Reimbursement of mental health care expenses is a significant issue impacting a patient's ability to gain access to care, as bipolar disorder is a costly disease to treat. Improving access to care among the bipolar community will require multilateral strategies to influence the actions and attitudes of patients, communities, providers, health care systems, and state/national governments. In other cultures, barriers to care differ according to a number of factors such as type of services, explanatory models of illness, misdiagnosis and perceptions of care givers. It is essential that clinicians are aware of pathways and barriers so that appropriate and accessible care can be provided.

Abstract
OBJECTIVES Caring for a relative with schizophrenia or dementia has been associated with reports of caregiver burden, symptoms of anxiety, depression, poor self-rated health, and elevated health service use; however, comparable data for caregivers of relatives with bipolar disorder are lacking. This study reports preliminary data on the health, psychological distress and health service use of caregivers of patients with bipolar disorder. It additionally evaluates the relationship of the level of burden caregivers report experiencing to their use of health services, controlling for level of psychological distress and health status. METHODS Subjects were primary caregivers of 264 patients with Research Diagnostic Criteria-diagnosed bipolar disorder and their bipolar relatives. Caregiver mental health and primary care service use were assessed retrospectively for the 7-month period prior to inpatient or outpatient admission of the bipolar patient. Caregiver depression, anxiety, medical conditions and patient symptomatology were assessed as well. RESULTS Hierarchical logistic regression analysis demonstrated that caregiver burden significantly increased the likelihood of mental health service use (OR = 13.53, p < 0.001) even after controlling for caregiver psychological distress and medical conditions, while anxiety and depression level, but not burden, significantly increased the likelihood of primary care service use, controlling for other variables (OR = 1.72, p = 0.02). CONCLUSIONS Burdens experienced by family caregivers appear to increase use of health services, and presumably cost, and may be reduced by psychosocial intervention.

Abstract
Continuity of care is a concern for individuals with persistent mental illness who need diverse services over time in response to multiple and changing needs. Efforts to study continuity have been hampered by lack of appropriate instruments. The Alberta Continuity of Services Scale--Mental Health is a newly developed, self-report scale that assesses continuity of care across settings and providers. This study examined the structure, reliability, and validity of the measure among users of community mental health programs. Findings were positive. Scores captured both positive and negative perceptions of care. Factor analyses elucidated 3 components of continuity--system access, interpersonal aspects, and care team function. Associations between the continuity scores and selected client and service use measures supported its validity. The tool holds promise for system monitoring, but would need refinements to create a shorter, conceptually clearer version. Also, performance among individuals with mild and very severe levels of mental illness needs to be evaluated.

Abstract
Cognitive interventions for bipolar disorder have received increased attention, but very few prospective studies have focused on whether cognitive variables predict the course of bipolar disorder. Available studies have yielded conflicting results concerning the effects of negative cognitions on mania. In this study, 60 individuals with bipolar I disorder completed monthly symptom severity interviews. At a 6-month follow-up, they completed the Dysfunctional Attitudes Scale, the Negative Automatic Thoughts Questionnaire, and the Positive Automatic Thoughts Questionnaire. Participants then completed monthly symptom severity interviews for another 6 months. Cognitive scales were correlated with current depression and predicted increases in depression over time, but were not related to mania. Although results do not support negative cognitions as a predictor of mania, they do provide support for the increasingly common use of cognitive interventions to treat bipolar depression.

Abstract
OBJECTIVE To review the available literature on psychoeducation and cognitive-behavioral therapy (CBT) in bipolar disorder (BD) and to give an integral view of these therapies. METHOD Studies were identified through Medline searches in English language publications between 1971 and 2003. This was supplemented by a hand search and the inclusion of selected descriptive articles on good clinical practice. RESULTS A number of studies demonstrate that psychoeducation enhances adherence to treatment, and one finds that it improves outcome in BD. Other studies find that CBT diminishes depressive symptoms and improves quality of life in BD. Occasionally some adverse effects may occur with psychotherapy and, although they are sporadic, should not be overlooked. CONCLUSION When combined with pharmacological treatment, psychoeducation helps to improve adherence. Training in the identification of early manic symptoms helps to improve outcomes and decreases the number of manic relapses in BD.

Abstract
Affective disorders impose a substantial individual and societal burden. Despite availability of efficacious treatments and practice guidelines, unmet need remains high. To reduce unmet need and the burden of affective disorders, information is needed on the distribution of burden across stakeholders, on barriers to reducing burden, and on interventions that effectively reduce burden at the levels of practice, community, and policy. This article provides the report of the Working Group on Overcoming Barriers to Reducing the Burden of Affective Disorders, for the National Institute of Mental Health Strategic Plan on Mood Disorders. We review the literature, identify key gaps, and recommend new research to guide national efforts to reduce the burden of affective disorders.

Abstract
Despite the availability of efficacious treatments for bipolar disorder, their effectiveness in general clinical practice is greatly attenuated, resulting in what has been called an 'efficacy-effectiveness gap'. In designing VA Cooperative Studies Program (CSP) Study #430 to address this gap, nine principles for conducting an effectiveness (in contrast to an efficacy) study were identified. These principles are presented and discussed, with specific aspects of CSP #430 serving as illustrations of how they can be implemented in an actual study. CSP #430 hypothesizes that an integrated, clinic-based treatment delivery system that emphasizes (1) algorithm-driven somatotherapy, (2) standardized patient education, and (3) easy access to a single primary mental health care provider to maximize continuity-of-care, will address the efficacy-effectiveness gap and improve disease, functional, and economic outcome. It is an 11-site, randomized controlled clinical trial of this multi-modal, clinic-based intervention versus usual VA care running from 1997 to 2003. The trial has enrolled 191 subjects in each arm, using minimal exclusion criteria to maximize the external validity of the study. Subjects are followed for 3 years. The intervention is highly specified in a series of operations manuals for each of the three components. Several continuous quality improvement (CQI) interventions, process measures, and statistical techniques deal with drift of care in both the intervention and usual care arms to ensure the internal validity of the study. CSP #430 is designed to have impact well beyond the VA, since it evaluates a basic health care operational principle: that augmenting ambulatory access for major mental illness will improve outcome and reduce overall treatment costs. If results are positive, this study will provide a reason to reconsider the prevailing trend toward limitation of ambulatory services that is characteristic of many managed care systems today.

Abstract
Bipolar disorder remains a high morbidity and costly illness in general clinical practice, despite the availability of efficacious medications. This 'efficacy-effectiveness gap' may be addressed by better organizing systems of care. One type of intervention is the 'collaborative practice model' which can be defined as an organization of care that a) emphasizes development in the patient of illness management skills, and b) supports provider capability and availability in order to c) engage patients in timely, joint decision-making regarding their illness. This article describes such a collaborative practice model for bipolar disorder, designed to be widely adoptable and sustainable in general clinical practice. The first part of the article describes the theoretical background from which the collaborative practice approach developed, emphasizing its origins in the lithium clinics of the 1970s, in nursing theory and practice, and more recently in the management of chronic medical diseases. The second part describes the structure of one such intervention, the Bipolar Disorders Program (BDP) developed in the Veterans Affairs health care system. The third part summarizes results from single-site studies of the intervention. The fourth part describes several key issues in its implementation in an ongoing multi-site randomized controlled trial, VA Cooperative Study Program (CSP) # 430. Data to date indicate that such collaborative practice interventions may improve important process and intermediate outcome variables for bipolar disorder. The BDP provides an example of a multi-faceted collaborative practice model that can be manualized and implemented across multiple sites in a randomized controlled trial.

Abstract
BACKGROUND Review of published studies reveals few data regarding determinants of the poor functional outcome and high healthcare costs that are characteristic of bipolar disorder. In order to identify potential mechanisms, critical to designing optimal treatment strategies, this longitudinal study investigated (a) the degree to which disease outcome is correlated with functional outcome and direct treatment costs, and (b) whether similar demographic or clinical characteristics predict disease and functional outcome and healthcare costs. METHODS Disease and functional outcome were assessed in bimonthly structured interviews over 48 weeks in 43 outpatient veterans with bipolar disorder. Direct mental health treatment costs from the VA perspective were determined from the VA database and patient interview. Regression analysis was used to determine association among the three outcome domains, and to identify clinical or demographic variables that predicted each of the three domains. RESULTS Functional outcome was correlated with depressive, but not manic, symptoms during follow-up. Costs were not correlated with any measure of disease or functional outcome. Several demographic, but not clinical, characteristics predicted functional outcome. In contrast, several clinical, but not demographic, characteristics predicted symptom status. No predictors were associated with direct treatment costs. LIMITATIONS Subjects were predominantly male veterans of relatively homogeneous social class, followed prospectively for approximately one year in a clinic designed specifically to minimize barriers to care. CONCLUSIONS Data from this and prior studies indicate that ongoing depressive symptoms are strongly associated with functional outcome, although substantial variance remains unexplained. Optimal models to explain functional outcome and healthcare costs will need to address factors besides simply disease severity and chronicity. The authors present a heuristic paradigm for understanding both the research and therapeutic aspects of these findings.

Abstract
Bipolar disorder has been conceptualized as an outcome of dysregulation in the behavioral activation system (BAS), a brain system that regulates goal-directed activity. On the basis of the BAS model, the authors hypothesized that life events involving goal attainment would promote manic symptoms in bipolar individuals. The authors followed 43 bipolar I individuals monthly with standardized symptom severity assessments (the Modified Hamilton Rating Scale for Depression and the Bech-Rafaelsen Mania Rating Scale). Life events were assessed using the Goal Attainment and Positivity scales of the Life Events and Difficulties Schedule. As hypothesized, manic symptoms increased in the 2 months following goal-attainment events, but depressed symptoms were not changed following goal-attainment events. These results are congruent with a series of recent polarity-specific findings.

Abstract
OBJECTIVE The Internal State Scale (ISS) is a self-report instrument that has been validated for discriminating mood states in patients with bipolar disorder. This study a) extends investigation to a multisite public sector sample and b) tests a revised scoring algorithm that formally identifies patients in mixed states. METHODS Eighty-six patients with bipolar disorder from four Veterans Affairs medical centers were assessed in a cross-sectional design. Physician-conducted semi-structured interviews used DSM-IV criteria to identify subjects as meeting criteria for euthymia, mania or hypomania, depression, or mixed state (mania or hypomania plus depression). A revised ISS scoring algorithm independently assigned mood state. Mean subscale scores were analyzed across groups. Receiver-operating characteristic (ROC) curve analysis was conducted to determine optimal algorithm structure. RESULTS Analysis of mean scores for the ISS subscales replicated original results for Activation, Well-Being, and Perceived Conflict, but indicated differences from the original results for the Depression Index. The ROC curve analysis identified optimal cut-off scores for the revised algorithm. The overall kappa score indicated moderate agreement between ISS and physician ratings of mood state, including mixed states. LIMITATIONS The study used a sample consisting primarily of male veterans. Mood state was assigned by experts using expert clinician diagnosis, not structured interviews. CONCLUSION The performance of the ISS in this multisite, public sector sample was similar to the performance in the initial research clinic sample. This finding confirms the validity of the ISS as a discriminator of mood states in bipolar disorder. The development of a revised scoring algorithm makes feasible formal identification of mixed episodes with the ISS.

Abstract
Bipolar disorder has been conceptualized as an outcome of dysregulation in the behavioral activation system (BAS), a brain system that regulates goal-directed activity. On the basis of the BAS model, the authors hypothesized that life events involving goal attainment would promote manic symptoms in bipolar individuals. The authors followed 43 bipolar I individuals monthly with standardized symptom severity assessments (the Modified Hamilton Rating Scale for Depression and the Bech-Rafaelsen Mania Rating Scale). Life events were assessed using the Goal Attainment and Positivity scales of the Life Events and Difficulties Schedule. As hypothesized, manic symptoms increased in the 2 months following goal-attainment events, but depressed symptoms were not changed following goal-attainment events. These results are congruent with a series of recent polarity-specific findings.
