Background How is emotion disrupted in bipolar disorder? Two studies are presented that adopt a multi-method approach to investigate emotion reactivity and emotion recovery in bipolar I disorder. Methods Across both studies, individuals with inter-episode bipolar disorder and healthy controls were shown three emotion-eliciting films (neutral, happy, and sad) and experiential and physiological responses were measured. In Study 1, bipolar (BD; n = 23) and non-clinical control (NC; n = 24) participants' emotional reactivity during film clips was assessed. In Study 2, a separate sample of BD (n = 23) and NC (n = 25) participants' emotion recovery was assessed after the film clips were assessed. Results Results indicated that the BD group exhibited increased self-reported positive emotion and respiratory sinus arrhythmia across all films compared to the NC group. There were no group differences in emotion recovery. Discussion Taken together, these results suggest that bipolar disorder is associated with increased positive emotion reactivity, but not emotion recovery, across contexts.

MCIDs validated in this study allow better interpretation of changes in MFI sub-scale scores and allow effect size calculations for determining sample size in future studies.

The CAN-FIT programme did not significantly improve the primary outcome, level of fatigue, regardless of when it was delivered, however, significant changes were observed in activity-based outcomes. Further investigations into educationally based programmes should target activity participation rather than changes in underlying fatigue to improve overall patient health.

Background Deficits in emotion perception and social functioning are strongly implicated in bipolar disorder (BD). Examining theory of mind (ToM) may provide one potential mechanism to explain observed socio-emotional impairments in this disorder. The present study prospectively investigated the relationship between theory of mind performance and life functioning in individuals diagnosed with BD compared to unipolar depression and healthy control groups. Methods Theory of mind (ToM) performance was examined in 26 individuals with remitted bipolar I disorder (BD), 29 individuals with remitted unipolar depression (UD), and 28 healthy controls (CTL) using a well-validated advanced theory of mind task. Accuracy and response latency scores were calculated from the task. Life functioning was measured during a 12 month follow-up session. Results No group differences for ToM accuracy emerged. However, the BD group exhibited significantly shorter response times than the UD and CTL groups. Importantly, quicker response times in the BD group predicted greater life functioning impairment at a 12-month follow-up, even after controlling for baseline symptoms. Limitations The stimuli were static representations of emotional states and do not allow for evaluating the appropriateness of context during emotional communication; due to sample size, neither specific comorbidities nor medication effects were analyzed for the BD and UD groups; preliminary status of theory of mind as a construct. Conclusions Results suggest that quickened socio-emotional decision making may represent a risk factor for future functional impairment in BD.

BACKGROUND: Cancer-related fatigue can be measured as both a unidimensional and a multidimensional construct. Unidimensional fatigue and its symptom correlates have undergone some previous investigation; however, minimal research has considered the differential effect of correlates on individual dimensions of fatigue. The objective of the current study was to investigate cancer-related fatigue in a radiotherapy sample using a multidimensional conceptualization to determine whether correlates of fatigue are consistent across all dimensions or whether each fatigue dimension has its own unique pattern of correlates. METHODS: The study used a prospective cohort design with data collected from radiotherapy patients at 3 time points; before, after, and 6 weeks after radiotherapy treatment. RESULTS: A total of 210 participants were enrolled in the study. Results indicated the following relations. Increased general fatigue was found to be associated with lower performance status, being in a de facto relationship, depression, having treatment to the brain, and reduced vigorous physical activity. Increased physical fatigue was associated with lower performance status, depression, reduced physical activity, reduced productive hours, and nausea. Higher levels of reduced activity were associated with depression, decreased participation in activities of daily living, decreased number of productive hours, and lower performance status. Higher levels of reduced motivation were associated with radiotherapy to the brain, reduced moderate physical activity, and depression. Increased mental fatigue was associated with diagnosis of a brain tumor, anxiety, depression, and sleep problems. CONCLUSIONS: The results of the current study support the recognition of multiple dimensions of fatigue, because each dimension examined had various correlates. These findings further develop our understanding of fatigue and may help clinicians provide more targeted information to people with cancer-related fatigue. Furthermore, these results can guide the development of group or individually tailored interventions that ultimately may reduce the impact of this distressing symptom on people with cancer.

Bipolar disorder is a disorder of emotion regulation. Less is known, however, about the specific processes that foster the maintenance of such prolonged and intense emotions-particularly positive-over time in this disorder. We investigated group-related differences in the ability to maintain positive and negative emotion representations over time using a previously validated emotion working memory task (Mikels et al., 2005, 2008) among individuals with bipolar I disorder (BD; n = 29) compared with both major depressive disorder (MDD; n = 29) and healthy control (n = 30) groups. Results revealed that the BD group exhibited a selective deficit in maintaining negative-but not positive-emotions compared to both the MDD and the control groups. The MDD and control groups did not differ significantly. These findings suggest that the heightened magnitude and duration of positive emotion observed in BD may, in part, be accounted for by difficulties maintaining negative emotions.

Enactment and enforcement of school nutrition policies represent key components in adolescent overweight and obesity prevention. This study determined: 1) California school board members' attitudes, perceptions, and motivations related to enactment of policies that support healthy eating in schools; and 2) barriers to adopting school policies that support healthy eating. To understand board members' decision-making process, key informant interviews were conducted and a survey was administered to 404 school board members. Though school board members care about the well-being of pupils, competing priorities limit the extent to which nutrition issues get addressed at board meetings. Members' decisions center primarily around academic achievement issues, yet they are interested in nutrition's overall impact on children's health and academic achievement.
