Regulating Positive Emotions: Implications for Promoting Well-Being in Individuals with Depression

Experiencing positive emotions is paramount to derive vitality from daily lived experiences. Positive emotions are associated with a range of beneficial outcomes, including longevity, reduced incidents of stroke, improved sleep quality, larger social networks, increased prosocial behavior, lower cortisol levels, and increased endogenous opioids and oxytocin. Despite these benefits, only limited research has focused on understanding positive emotion regulation within the context of depression. Rather, mechanisms related to the regulation of negative emotion have been the focus of research and evidence-based treatments. This interdisciplinary review article aims to advance knowledge regarding the role of positive emotion regulation in individuals with depression to inform the development of transdiagnostic evidenced-based approaches to treatment that bolster the experience of positive life events. We drew on research findings across the fields of clinical psychology, affective science, and social psychology to identify future directions for novel interdisciplinary translational research regarding mechanisms associated with positive emotion regulation

Life of the enlisted soldier on the western frontier

In contrast to the relatively rapid changes occurring in the modern American army, the period between the end of the War of 1812 and the beginning of the Mexican War offers a definite period for a study of military life when reform came slowly

The Role of the Library in the Undergraduate Experience: A Case Study at Duke University's Lilly Library

This study's purpose is to gain a better understanding of the role of the academic library in the overall collegiate experience of undergraduate students. Ten undergraduate students at Duke University were interviewed regarding their use of Lilly Library, a branch library with a primarily undergraduate clientele. Their responses were coded and analyzed to determine trends in their use of and attitudes toward the library. By examining why and how students use the library as an academic and community space in ways that are not necessarily observable by librarians, the profession can better meet the needs of this important user group

Differential Functional Connectivity of Rostral Anterior Cingulate Cortex During Emotional Interference

The rostral-ventral subdivision of the anterior cingulate cortex (rACC) plays a key role in the regulation of emotional processing. Although rACC has strong anatomical connections with anterior insular cortex (AIC), amygdala, prefrontal cortex and striatal brain regions, it is unclear whether the functional connectivity of rACC with these regions changes when regulating emotional processing. Furthermore, it is not known whether this connectivity changes with deficits in emotion regulation seen in different kinds of anxiety and depression. To address these questions regarding rACC functional connectivity, non-patients high in self-reported anxious apprehension (AP), anxious arousal (AR), anhedonic depression (AD) or none (CON) indicated the ink color of pleasant, neutral and unpleasant words during functional magnetic resonance imaging. While ignoring task-irrelevant unpleasant words, AD and CON showed an increase in the functional connectivity of rACC with AIC, putamen, caudate and ventral pallidum. There was a decrease in this connectivity in AP and AR, with AP showing greater reduction than AR. These findings provide support for the role of rACC in integrating interoceptive, emotional and cognitive functions via interactions with insula and striatal regions during effective emotion regulation in healthy individuals and a failure of this integration that may be specific to anxiety, particularly AP

Electrophysiological evidence of the time course of Attentional Bias in Nonpatients Reporting Symptoms of Depression With and Without Co-Occurring Anxiety

Anxiety is characterized by attentional biases to threat, but findings are inconsistent for depression. To address this inconsistency, the present study systematically assessed the role of co-occurring anxiety in attentional bias in depression. In addition, the role of emotional valence, arousal, and gender was explored. Ninety-two non-patients completed the Penn State Worry Questionnaire (Meyer et al., 1990; Molina and Borkovec, 1994) and portions of the Mood and Anxiety Symptom Questionnaire (Watson et al., 1995a,b). Individuals reporting high levels of depression and low levels of anxiety (depression only), high levels of depression and anxiety (combined), or low levels of both (control) completed an emotion-word Stroop task during event-related brain potential recording. Pleasant and unpleasant words were matched on emotional arousal level. An attentional bias was not evident in the depression-only group. Women in the combined group had larger N200 amplitude for pleasant than unpleasant stimuli, and the combined group as a whole had larger right-lateralized P300 amplitude for pleasant than unpleasant stimuli, consistent with an early and later attentional bias that is specific to unpleasant valence in the combined group. Men in the control group had larger N200 amplitude for pleasant than unpleasant stimuli, consistent with an early attentional bias that is specific to pleasant valence. The present study indicates that the nature and time course of attention prompted by emotional valence and not arousal differentiates depression with and without anxiety, with some evidence of gender moderating early effects. Overall, results suggest that co-occurring anxiety is more important than previously acknowledged in demonstrating evidence of attentional biases in depression

Neural Correlates of Suspiciousness and Interactions with Anxiety During Emotional and Neutral Word Processing

Suspiciousness is usually classified as a symptom of psychosis, but it also occurs in depression and anxiety disorders. Though how suspiciousness overlaps with depression is not obvious, suspiciousness does seem to overlap with anxious apprehension and anxious arousal (e.g., verbal iterative processes and vigilance about environmental threat). However, suspiciousness also has unique characteristics (e.g., concern about harm from others and vigilance about social threat). Given that both anxiety and suspiciousness have been associated with abnormalities in emotion processing, it is unclear whether it is the unique characteristics of suspiciousness or the overlap with anxiety that drive abnormalities in emotion processing. Event-related brain potentials were obtained during an emotion-word Stroop task. Results indicated that suspiciousness interacts with anxious apprehension to modulate initial stimulus perception processes. Suspiciousness is associated with attention to all stimuli regardless of emotion content. In contrast, anxious arousal is associated with a later response to emotion stimuli only. These results suggest that suspiciousness and anxious apprehension share overlapping processes, but suspiciousness alone is associated with a hyperactive early vigilance response. Depression did not interact with suspiciousness to predict response to emotion stimuli. These findings suggest that it may be informative to assess suspiciousness in conjunction with anxiety in order to better understand how these symptoms interact and contribute to dysfunctional emotion processing

Savoring the moment: A link between affectivity and depression

Objective: Positive affectivity (PA; disposition to experience positive moods) and negative affectivity (NA; disposition to experience negative moods) may be risk factors for depression. Low PA may impair positive emotion regulation (savoring), potentially exacerbating depression. Understanding the mechanisms in which temporal domains of savoring influence the relationship between affectivity and depression may help advance depression treatments.Method: 1,618 participants (1,243 females; 70.0% Caucasian, 19.1% Asian, 4.5% African American, 0.9% Pacific Islander, 0.7% American Indian or Alaskan Native, 4.9% Biracial) ages 17 - 40 (M = 18.99, SD = 1.33) completed questionnaires. An exploratory path analysis was run with PA and NA as exogenous variables, savoring domains as mediators, and depression the outcome.Results: PA and NA were associated with depression and all three savoring temporal domains. Momentary savoring distinctly mediated the relationship between both PA and NA and depression.Limitations: The data are self-report and cross-sectional, precluding causal inference. Post-hoc power analysis indicated that the present study was underpowered. The use of a college sample primarily comprised of Caucasian women limits generalizability.Conclusions: Affectivity was associated with the temporal domains of savoring and indirectly associated with depression via momentary savoring. All temporal domains of savoring may bolster PA and mitigate NA. Momentary savoring may reduce depression symptoms in individuals with low PA and high NA
