Addressing climate change with behavioral science: A global intervention tournament in 63 countries

Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior-several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.

Social and moral psychology of COVID-19 across 69 countries

The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behaviour change. To help scholars better understand the social and moral psychology behind public health behaviour, we present a dataset comprising of 51,404 individuals from 69 countries. This dataset was collected for the International Collaboration on Social & Moral Psychology of COVID-19 project (ICSMP COVID-19). This social science survey invited participants around the world to complete a series of moral and psychological measures and public health attitudes about COVID-19 during an early phase of the COVID-19 pandemic (between April and June 2020). The survey included seven broad categories of questions: COVID-19 beliefs and compliance behaviours; identity and social attitudes; ideology; health and well-being; moral beliefs and motivation; personality traits; and demographic variables. We report both raw and cleaned data, along with all survey materials, data visualisations, and psychometric evaluations of key variables.

Young Adult Mental Health Beyond the COVID-19 Era: Can Enlightened Policy Promote Long-Term Change?

The status of mental health for adolescents and young adults has aptly been termed a "crisis" across research, clinical, and policy quarters. Arguably, the status quo provision of mental health services for adolescents and young adults is neither acceptable nor salvageable in its current form. Instead, only a wholesale policy transformation of mental health sciences can address crises of this scope. Pandemic-related impacts on mental health, particularly among young adults, have clearly exposed the need for the mental healthcare field to develop a set of transformative priorities to achieve long overdue, systemic changes: (1) frequent mental health tracking, (2) increased access to mental health care, (3) working with and within communities, (4) collaboration across disciplines and stakeholders, (5) prevention-focused emphasis, (6) use of dimensional descriptions over categorical pronouncements, and (7) addressing systemic inequities. The pandemic required changes in mental healthcare that can and should be the beginning of long-needed reform, calling upon all mental health care disciplines to embrace innovation and relinquish outdated traditions.

[2022 Update of the Austrian Society for Rheumatology and Rehabilitation nutrition and lifestyle recommendations for patients with gout and hyperuricemia]

BACKGROUND

Gout is the most frequent inflammatory joint disease in the western world and has a proven genetic background. Additionally, lifestyle factors, such as increasing life expectation and standard of living, sufficient or excess nutrition and a growing prevalence of obesity in the population as well as e.g. alcohol consumption, contribute to the rising incidence of hyperuricemia and gout. Apart from an adequate medication, medical consultation on nutrition and lifestyle is an essential part of the management of gout patients, who have a high risk of internal comorbidities.

OBJECTIVE

In 2015 the Austrian Society for Rheumatology and Rehabilitation (ÖGR) working group for osteoarthritis and crystal arthropathies published nutrition and lifestyle recommendations for patients with gout and hyperuricemia. Since then, a multitude of studies have been published addressing this topic, which necessitated an update.

METHODS

First, the authors performed a hierarchical literature search to screen for the literature published since 2015. Considering references given in the first publication, the relevant literature was selected and the recommendations from 2015 were either kept as published, reformulated or recreated. Finally, the evidence level and the level of agreement for each recommendation were added by the authors.

RESULTS

Based on this process, 10 recommendations were generated instead of the initial 9. As in the original publication, a graphical presentation with symbols was constructed to complement the written text.

CONCLUSION

The ÖGR recommendations on nutrition and lifestyle for patients with gout and hyperuricemia were updated in accordance with the most recent relevant literature. These are supposed to serve as information and education material for patients and updated information for physicians.

High volume retrograde portography for better discrimination of the portal vein during TIPS procedure

Background: Imaging of the portal vein prior to puncture for TIPS is essential.

Purpose: With this study, we examined a modified retrograde portography with regard to the reliable representation of the portal vein.

Material and Methods: Prospective evaluation of 65 TIPS interventions with regard to the delimitation of the portal vein and the exact parameters of retrograde portography such as catheter diameter and contrast medium volume per injection.

Results: Retrograde portographies with a large-lumen catheter (10 F) and a large contrast medium volume (40 mL) were performed in 35/63 patients with significantly better delineation of the portal vein than when using 5 F catheters with 10 mL contrast medium.

Conclusion: The so-called high volume retrograde portography leads to better delimitation of the portal vein during TIPS application.

Predicting attitudinal and behavioral responses to COVID-19 pandemic using machine learning

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied machine learning on the multinational data collected by the International Collaboration on the Social and Moral Psychology of COVID-19 (N = 51,404) to test the predictive efficacy of constructs from social, moral, cognitive, and personality psychology, as well as socio-demographic factors, in the attitudinal and behavioral responses to the pandemic. The results point to several valuable insights. Internalized moral identity provided the most consistent predictive contribution-individuals perceiving moral traits as central to their self-concept reported higher adherence to preventive measures. Similar results were found for morality as cooperation, symbolized moral identity, self-control, open-mindedness, and collective narcissism, while the inverse relationship was evident for the endorsement of conspiracy theories. However, we also found a non-neglible variability in the explained variance and predictive contributions with respect to macro-level factors such as the pandemic stage or cultural region. Overall, the results underscore the importance of morality-related and contextual factors in understanding adherence to public health recommendations during the pandemic.

Leveraging the Strengths of Psychologists With Lived Experience of Psychopathology

Psychopathology is a common element of the human experience, and psychological scientists are not immune. Recent empirical data demonstrate that a significant proportion of clinical, counseling, and school psychology faculty and graduate students have lived experience, both past and present, of psychopathology. This commentary compliments these findings by leveraging the perspectives of the authors and signatories, who have personal lived experience of psychopathology, to improve professional inclusivity in these fields. By "coming out proud," the authors aim to foster discussion, research, and inclusion efforts as they relate to psychopathology experiences in psychological science. To that end, the authors describe considerations related to disclosure of lived experience, identify barriers to inclusion, and provide concrete recommendations for personal and systemic changes to improve recognition and acceptance of psychopathology lived experience among psychologists.

National identity predicts public health support during a global pandemic

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g., spatial distancing and stricter hygiene) and endorsed public policy interventions (e.g., closing bars and restaurants) during the early stage of the COVID-19 pandemic (April-May 2020). Respondents who reported identifying more strongly with their nation consistently reported greater engagement in public health behaviours and support for public health policies. Results were similar for representative and non-representative national samples. Study 2 (N = 42 countries) conceptually replicated the central finding using aggregate indices of national identity (obtained using the World Values Survey) and a measure of actual behaviour change during the pandemic (obtained from Google mobility reports). Higher levels of national identification prior to the pandemic predicted lower mobility during the early stage of the pandemic (r = -0.40). We discuss the potential implications of links between national identity, leadership, and public health for managing COVID-19 and future pandemics.

Laughter and short-term blood pressure reactivity in middle-aged and older adult spousal support interactions

OBJECTIVE

Theories suggest that laughter decreases negative affect and enhances social bonds; however, no studies have examined the benefits of laughter on stress biomarkers in dyads. This study examined the hypotheses that individual and shared laughter would be associated with lower blood pressure reactivity and decreased self-reported and perceived partner distress for the target and spouse in a social support interaction.

METHOD

One hundred seventy-three middle-aged and older adult couples from a larger study were video-recorded, and their blood pressure was monitored continuously in the laboratory during a resting baseline, during a social support interaction in which they discussed a target's fear related to aging, and while playing a game (used as a comparison). Both partners self-reported their own and perceived partner distress after the support interaction. Laughter behavior was coded using the Facial Action Coding System criteria.

RESULTS

According to Actor Partner Interdependence Models, during the support interaction, the more the target laughed, the lower the spouse's systolic blood pressure was (partner effect). Also, greater laughter was associated with less self-reported and perceived partner distress for targets and spouses (actor effects). There were no other significant associations between individual laughter, shared laughter, systolic or diastolic blood pressure, and distress. Models controlled for gender, marital satisfaction, baseline blood pressure, and the target's baseline distress rating of their fear.

CONCLUSIONS

In social support interactions, targets' laughter may have short-term blood pressure benefits for caregiving spouses and distress reducing benefits for both spouses. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

No group differences in Traditional Economics Measures of loss aversion and framing effects in bipolar I disorder

Bipolar disorder (BD) is associated with impaired decision making, yet few studies have adopted paradigms from behavioral economics to decompose which, if any, aspects of decision making may be impacted. This may be particularly relevant for decision-making processes relevant to known difficulties with emotive dysfunction and corresponding reward dysregulation in BD. Participants with bipolar I disorder (BD; n = 44) and non-psychiatric healthy controls (CTL; n = 28) completed three well-validated behavioral economics decision making tasks via a remote-based survey, including loss aversion and framing effects, that examined sensitivity to probabilities and potential gains and losses in monetary and non-monetary domains. Consistent with past work, we found evidence of moderate loss aversion and framing effects across all participants. No group differences were found in any of the measures of loss aversion or framing effects. We report no group differences between bipolar and non-psychiatric groups with respect to loss aversion and framing effects using a remote-based survey approach. These results provide a framework future studies to explore similar tasks in clinical populations and suggest the context and degree to which decision making is altered in BD may be rooted in a more complex cognitive mechanism that warrants future research.

Assessing Emotion Regulation Ability for Negative and Positive Emotions: Psychometrics of the Perth Emotion Regulation Competency Inventory in United States Adults

People regulate both negative and positive emotions, and their ability to do this successfully is a cornerstone of adaptive psychological functioning. However, few measures have been available to assess emotion regulation ability across both valence domains. The Perth Emotion Regulation Competency Inventory (PERCI) was recently developed for this purpose. Here we present the first psychometric study of the PERCI in the United States (N = 508). Confirmatory factor analyses supported the intended eight-factor structure, which was invariant across age, gender, and education. PERCI scores had high internal consistency, and were associated with measures of psychopathology, emotional reactivity, and emotion regulation strategies in expected ways. These observed relationships between the PERCI and various regulation strategies may serve to establish a profile of what strategy patterns characterize differences in emotion regulation ability. Overall, the PERCI had strong psychometrics. Its capacity to assess both valence domains should enable more comprehensive assessments of emotion regulation ability.

Emotional regularity: associations with personality, psychological health, and occupational outcomes

Emotional regularity is the degree to which a person maintains and returns to a set of emotional states over time. The present investigation examined associations between emotional regularity and extant emotion measures as well as psychologically relevant dimensions of personality, health, and real-world occupational outcomes. Participants included 598 U.S. adults who provided daily experience sampling reports on their emotional states for approximately two months. Results suggest that emotional regularity was related to, but distinct from, well-established measures of emotion including emotional intensity, variability, covariation, inertia, granularity, and emodiversity. Furthermore, emotional regularity significantly predicted measures of personality, psychological health, and occupational outcomes even when accounting for extant emotion measures and sociodemographic covariates. Finally, it explained modest (7.5%) improvement (in terms of cross-validated RSq.) over baseline models containing emotional intensity, variability, and sociodemographic covariates. These findings suggest that emotional regularity may provide an important indicator of healthy emotional functioning and may be a promising area for further scientific discovery.

Mental health and clinical psychological science in the time of COVID-19: Challenges, opportunities, and a call to action

COVID-19 presents significant social, economic, and medical challenges. Because COVID-19 has already begun to precipitate huge increases in mental health problems, clinical psychological science must assert a leadership role in guiding a national response to this secondary crisis. In this article, COVID-19 is conceptualized as a unique, compounding, multidimensional stressor that will create a vast need for intervention and necessitate new paradigms for mental health service delivery and training. Urgent challenge areas across developmental periods are discussed, followed by a review of psychological symptoms that likely will increase in prevalence and require innovative solutions in both science and practice. Implications for new research directions, clinical approaches, and policy issues are discussed to highlight the opportunities for clinical psychological science to emerge as an updated, contemporary field capable of addressing the burden of mental illness and distress in the wake of COVID-19 and beyond.

The Future of Women in Psychological Science

There has been extensive discussion about gender gaps in representation and career advancement in the sciences. However, psychological science itself has yet to be the focus of discussion or systematic review, despite our field's investment in questions of equity, status, well-being, gender bias, and gender disparities. In the present article, we consider 10 topics relevant for women's career advancement in psychological science. We focus on issues that have been the subject of empirical study, discuss relevant evidence within and outside of psychological science, and draw on established psychological theory and social-science research to begin to chart a path forward. We hope that better understanding of these issues within the field will shed light on areas of existing gender gaps in the discipline and areas where positive change has happened, and spark conversation within our field about how to create lasting change to mitigate remaining gender differences in psychological science.

Associations between hypomania proneness and attentional bias to happy, but not angry or fearful, faces in emerging adults

Mania, the core feature of bipolar disorder, is associated with heightened and positive emotion responding. Yet, little is known about the underlying cognitive processes that may contribute to heightened positive emotionality observed. Additionally, while previous research has investigated positive emotion biases in non-clinical samples, few if any, account for subthreshold clinical symptoms or traits, which have reliably assessed psychopathological risk. The present study compared continuous scores on a widely used self-report measure of hypomania proneness (HPS-48) with a dot-probe task to investigate attentional biases for happy, angry, fearful, and neutral faces among 66 college student participants. Results suggested that hypomania proneness was positively associated with attentional bias towards happy, but not angry or fearful faces. Results remained robust when controlling for positive affect and did not appear to be affected by negative affect or current symptoms of depression, anxiety, and stress. Findings provide insight into potential behavioural markers that co-occur with heightened positive emotional responding and hypomania in emerging adults.

Best research practices in clinical science: Reflections on the status quo and charting a path forward

Clinical psychological science is a rapidly evolving field using a diverse set of methods in various populations. Many of our common research practices and everyday decisions on how and when to use certain methods are described with little detail and formal guidelines and open discussion of those (formal and informal) guidelines is often missing. This special section aims to take stock of current practices in our field and to reflect on them by providing user-friendly articles on common practices across a variety of methodologies in. The articles cover 4 broad areas: (a) diagnostic and clinical assessment including the importance of interrater reliability, the challenges of extreme group designs, and transdiagnostic approaches; (b) clinical neuroscience research including clinical psychophysiology work and translational neuroscience; (c) research conducted outside the laboratory setting including experience sampling and online studies; and (d) daily research practices. A particular focus is on how the discussed practices apply specifically to psychiatric and at-risk clinical populations and the unique methodological challenges that arise when working with these sensitive populations. The contributors to this special issue represent a diverse group whose efforts target a variety of settings and processes with the ultimate goal of increasing transparency surrounding our everyday decisions about designs, methods, and data analysis. We hope that each of the pieces in this section offer inspiration and provide a resource as well as a starting point for further discussion.

Understanding and Taking Stock of Positive Emotion Disturbance

The prevailing view on positive emotions is that they correlate with and confer psychological health benefits for the individual, including improved social, physical and cognitive functioning. Yet an emerging wave of scientific work suggests that positive emotions are also related to a range of suboptimal psychological health outcomes, especially when the intensity, duration, or context do not optimize the individual's goals or meet current environmental demands. This paper provides an overview of the 'other side' of positive emotion, by describing and reviewing evidence supporting the emerging field of Positive Emotion Disturbance (PED). We review relevant emotion processes and key themes of PED and apply this framework to example emotional disorders, and discuss implications for psychological change and future research agendas.

Best practices in research mentoring in clinical science

The growth of clinical science as a field depends on the work of engaged mentors nurturing future generations of scientists. Effective research mentoring has been shown to predict positive outcomes, including greater scholarly productivity, reduced attrition, and increased satisfaction with training and/or employment, which ultimately may enhance the quality of the clinical-science research enterprise. Barriers to effective research mentoring, however, pose significant challenges for both mentees and mentors, as well as for labs, training programs, and/or departments. We discuss some key issues as they apply to clinical-science mentoring and note how they are affected across different developmental levels (undergraduate, postbaccalaureate, doctoral, internship, postdoctoral associates, and early career faculty). Although we do not proclaim expertise on these issues-and have struggled with them in our own careers-we believe an open discussion around best mentoring practices will enhance our collective effectiveness and help mentees and our field to flourish.

Evaluations of affective stimuli modulated by another person's presence and affiliative touch

Affiliative touch carries affective meaning and affects the receiver. Although research demonstrates that receiving touch modulates the neural processing of emotions, its effects on evaluations of affective stimuli remain unexplored. The current research examined the effects of affiliative touch on the evaluation of affective images across 3 studies and aimed to disentangle the effect of another person's mere presence from the addition of affiliative touch. Participants thus underwent experimental conditions of social manipulation (presence, alone) and touch manipulations (receiving, self-providing, providing to experimenter) while viewing affective images (negative, neutral, and positive valence) and evaluated their valence. Study 1 included hand-squeezing (N = 39), and Study 2 included forearm-stroking (N = 40) in a within-subjects design. Study 3 included hand-squeezing (N = 109) in a between-subjects design. Across both studies, the results suggested that the receiving condition decreased the negativity of negative images, and the providing condition reduced the positivity of positive images. Furthermore, the other presence condition increased the positivity of positive images compared with the alone condition in Study 1 and to the receiving condition in Study 2. Hand-squeezing and forearm-stroking had differential effects on affective image evaluations depending on the image valence and who provided the touch. Overall, receiving touch seems to attenuate negative evaluations in negative contexts and the presence of others amplifies positive evaluations in positive situations. Discussion highlights the importance of affiliative touch within social interactions. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

P2519Multiprofessional intervention for fostering self management capabilities for patients with chronic heart disease - development of a common curriculum (MIFeSCH)

Background

Chronic cardiovascular disease (CAD) still is the leading cause of death in industrialized countries in spite of substantial progress in diagnostics and therapy. Programs of lifestyle management are effective but insufficiently established in usual patient care. The authors provide multi professional educational courses to strengthen self management capabilities for cardiovascular patients in five different institutions in Europe since up to 20 years in modification of the program of Dr. Dean Ornish. Physicians, psychologists, dietitians and artistic and movement therapists work together in courses lasting from half a year to one year.

To implement their programs in daily care, an association of these five institutions will evaluate a common lifestyle management program in four phases: 1. development of a common curriculum, 2. pilot study, 3. interventional study, 4. implementation study.

Phase 1 is now completed. The evaluation will show, whether this lifestyle management program leads to improvement of health in patients and in the therapeutic team.

Purpose of phase 1: development of a common curriculum by the five active members of the association.

Methods

The five existing educational programs were assessed and differences between the programs themselves and other existing programs of patient education were defined. Distinctive and common features of the different institutions were recorded. Structured interviews with members of all institutions acquired content, methods and eductional goals of the interventions according to predefined criteria for patient education programs in the respective countries. The results were discussed, reflected and a common curriculum was consented.

Results

The consented multi professional curriculum, comprising the activities of five active heart education programs defines five different levels of competence which are key of their patient education goals: (1) reflective self-awareness (I-competence), (2) artistic competence, (3) competence of ensouled movement, (4) nutritional competence and (5) social competence.

The main difference between the already existing programs for patients with CAD and the newly developed curriculum is the emphasis on training the participants' self awareness and social competence, for example by biography work in an interdisciplinary approach.

Levels of competence

Conclusion

The process of generating a common curriculum of competence levels, educational goals and necessary methods comprising the work of five different but associated institutions was successful. A pilot study will now be performed to show the effects of this program on cardiovascular health and quality of live of study participants and the therapeutic team as well to show, whether this intervention reduces the risk of burn out for the therapists.

By this the authors hope to implement their education program according to the curriculum as an improvement of standard therapy for patients with cardiovascular disease.

Robust, replicable, and theoretically-grounded: A response to Brown and Coyne's (2017) commentary on the relationship between emodiversity and health

In 2014 in the Journal of Experimental Psychology: General, we reported 2 studies demonstrating that the diversity of emotions that people experience-as measured by the Shannon-Wiener entropy index-was an independent predictor of mental and physical health, over and above the effect of mean levels of emotion. Brown and Coyne (2017) questioned both our use of Shannon's entropy and our analytic approach. We thank Brown and Coyne for their interest in our research; however, both their theoretical and empirical critiques do not undermine the central theoretical tenets and empirical findings of our research. We present an in-depth examination that reveals that our findings are statistically robust, replicable, and reflect a theoretically grounded phenomenon with real-world implications.

Broadening Our Field of View: The Role of Emotion Polyregulation

The field of emotion regulation has developed rapidly, and a number of emotion regulatory strategies have been identified. To date, empirical attention has focused on contrasting specific regulation strategies to determine their unique profile of consequences. However, it is becoming clear that people commonly pursue multiple regulation approaches within any given emotional episode (e.g., pursuing different regulation goals, strategies, or tactics). We refer to the concurrent or sequential use of multiple approaches to regulate emotions within a single emotion episode as polyregulation. Here, we extend existing theoretical frameworks of emotion regulation to consider polyregulation. We then pose several core questions to summarize and inspire research on polyregulation, thereby improving our understanding of emotion regulation as it unfolds in everyday life.

Beliefs about the automaticity of positive mood regulation: examination of the BAMR-Positive Emotion Downregulation Scale in relation to emotion regulation strategies and mood symptoms

Emotion regulation is a topic of great interest due to its relevance to navigating everyday life, as well as its relevance to psychopathology. Recent research indicates that beliefs about the automaticity of mood regulation are critical to psychological health. In the present study we assessed beliefs about the automaticity of positive mood regulation in relationship to self-reported mood symptoms and explicit emotion regulation strategies. Participants (n = 200) completed an online survey including a scale assessing beliefs about automatic downregulation of positive emotions (i.e. BAMR-PED), beliefs about automatic mood regulation for negative emotions, mood symptoms, and emotion regulation strategies. Results suggested that beliefs about automatic positive emotion regulation were associated with unhelpful emotion regulation strategies and reduced negative affect as well as fewer depressive, manic, and anxiety symptoms. Test-retest of the novel BAMR-PED measure was tested with a further sample (n = 46) and found to be acceptable. Future research should explore how these automatic beliefs have relevance to clinical disorders characterised by positive emotion disturbance, such as bipolar disorder.

Altered amygdala circuits underlying valence processing among manic and depressed phases in bipolar adults

BACKGROUND

Disruptions in affective processing characterize mood disorders, yet the neural mechanisms underlying internal state dependency in affective processes are not well understood. The present work presents a pilot investigation into state dependency among neural circuits known to be involved in processing affective information, by examining acute manic and depressive mood phases in adults with bipolar disorder and major depressive disorder.

METHODS

The present study probed affective processes with a well-validated passive picture-viewing task amongst acutely manic (n = 8) or acutely depressed (bipolar depression: n = 11; major depression: n = 15) mood-disordered adults during functional magnetic resonance imaging .

RESULTS

Beta-series correlation analyses seeded from the amygdala revealed distinct neural circuits distinguished across current mood state rather than diagnostic boundaries. We delineated an amygdala-striatum pathway that distinguished depressed from manic mood phase, rather than between diagnostic boundaries, in processing valenced information. Specifically, we found differences in this neural response to negative, but not positive, images across clinical mood states.

LIMITATIONS

As a preliminary investigation of state-dependent affective processes, the current investigation is predominantly limited by the small sample size. While it provides direction and generates hypotheses for further work, future studies need to replicate and expand the reported effects with larger samples.

CONCLUSIONS

These findings demonstrate the conditions under which mood state-dependent affective processes cut cross traditional diagnostic boundaries, speaking to recent advances in transdiagnostic disease mechanisms, and can guide future work examining the neural mechanisms driving symptomatology in affective disorders.

Lack of emotional gaze preferences using eye-tracking in remitted bipolar I disorder

BACKGROUND

Bipolar disorder is associated with heightened and persistent positive emotion (Gruber in Curr Dir Psychol Sci 20:217-221, 2011; Johnson in Clin Psychol Rev 25:241-262, 2005). Yet little is known about information processing biases that may influence these patterns of emotion responding.

METHODS

The current study adopted eye-tracking methodology as a continuous measure of sustained overt attention to monitor gaze preferences during passive viewing of positive, negative, and neutral standardized photo stimuli among remitted bipolar adults and healthy controls. Percentage fixation durations were recorded for predetermined areas of interest across the entire image presentation, and exploratory analyses were conducted to examine early versus late temporal phases of image processing.

RESULTS

Results suggest that the bipolar and healthy control groups did not differ in patterns of attention bias.

CONCLUSIONS

Findings provide insight into apparently intact attention processing despite disrupted emotional responding in bipolar disorder.

Neuroleptic-free youth at ultrahigh risk for psychosis evidence diminished emotion reactivity that is predicted by depression and anxiety

Although abnormalities in emotional response have long been considered a core feature of the chronic phase of schizophrenia, few investigations have examined emotional response in individuals at ultrahigh-risk (UHR) for psychosis. We investigated whether neuroleptic-free UHR (n=29) and healthy control (n=32) participants differed in emotional reactivity and emotion regulation on a laboratory-based task that required reporting levels of positive and negative affect to pleasant, unpleasant, and neutral stimuli. Results indicated that the UHR group evidenced reduced emotional reactivity, including decreased positive emotion to pleasant stimuli and decreased negative emotion to unpleasant stimuli. Furthermore, within the UHR group, attenuated positive emotion to pleasant stimuli was associated with greater severity of depression and anxiety. There were no group differences in self-reported emotion regulation effectiveness to unpleasant or pleasant stimuli. Findings suggest that UHR youth display a profile of emotional experience abnormalities that differs from the chronic phase of illness, which can be characterized as reduced positive emotion reactivity to pleasant stimuli (i.e., anhedonia) that may be driven by mood and anxiety symptoms.

You'll feel better in the morning: slow wave activity and overnight mood regulation in interepisode bipolar disorder

BACKGROUND

Sleep disturbances are prominent correlates of acute mood episodes and inadequate recovery in bipolar disorder (BD), yet the mechanistic relationship between sleep physiology and mood remains poorly understood. Using a series of pre-sleep mood inductions and overnight sleep recording, this study examined the relationship between overnight mood regulation and a marker of sleep intensity (non-rapid eye movement sleep slow wave activity; NREM SWA) during the interepisode phase of BD.

METHODS

Adults with interepisode BD type 1 (BD; n = 20) and healthy adult controls (CTL; n = 23) slept in the laboratory for a screening night, a neutral mood induction night (baseline), a happy mood induction night, and a sad mood induction night. NREM SWA (0.75-4.75 Hz) was derived from overnight sleep EEG recordings. Overnight mood regulation was evaluated using an affect grid pleasantness rating post-mood induction (pre-sleep) and the next morning.

RESULTS

Overnight mood regulation did not differ between groups following the sad or happy inductions. SWA did not significantly change for either group on the sad induction night compared with baseline. In BD only, SWA on the sad night was related to impaired overnight negative mood regulation. On the happy induction night, SWA increased relative to baseline in both groups, though SWA was not related to overnight mood regulation for either group.

CONCLUSIONS

These findings indicate that SWA disruption may play a role in sustaining negative mood state from the previous night in interepisode BD. However, positive mood state could enhance SWA in bipolar patients and healthy adults.

Veränderungen der Perforansvenen und tiefen Unterschenkelvenen nach Beseitigung des Saphena-Refluxes

Um zu testen, ob zwischen dem Saphenareflux einerseits und der Größe der Perforansvenen und dem am Privatkreislauf nach Trendelenburg teilnehmenden Teil der tiefen Unterschenkelvenen andererseits ein Zusammenhang besteht, wurden bei 31 Perforansvenen und 18 Venae tibialis posterior von 18 Patienten mit primärer Varikose und einem deutlichen Reflux in der Vena saphena magna Messungen des phlebographisch dargestellten Durchmessers vor und sechs Monate nach Beseitigung des Saphenarefluxes durchgeführt. Die Auswirkung der Operation wurde bei 15 Patienten mit Strain-gauge-Plethysmographie verifiziert. Die Messungen haben gezeigt, daß sich der Durchmesser sowohl der Perforansvenen als auch der Vena tibialis posterior sechs Monate nach Beseitigung des Saphenarefluxes statistisch signifikant verkleinert hat. Man kann den Schluß ziehen, daß der Saphenareflux eine wichtige Rolle bei der Erweiterung der Perforansvenen als auch des am Privatkreislauf nach Trendelenburg teilnehmenden Teils der tiefen Unterschenkelvenen spielt.

„Obesogenic environments“

Zielsetzung In der aktuellen Diskussion über die Auswirkungen des Wohnumfeldes auf die Gesundheit von Bewohnern wird die Existenz sogenannter “obesogenic environments” konstatiert. Diese Studie untersucht am Beispiel der Stadt Köln, ob sozial benachteiligte Wohngegenden tatsächlich ein besseres Angebot an ungesunden Nahrungsmitteln und ein schlechteres Angebot an gesunden Nahrungsmitteln aufweisen.

Design/Aufbau Diese ökologische Studie wurde in vier Stadtteilen Kölns mit 18 Sozialräumen (Wohnvierteln) und insgesamt 92 000 Einwohnern durchgeführt. Dabei wurde die Gesamtanzahl aller Verkaufsstellen für Fast Food und Obst und Gemüse erfasst, mittels eines Geographischen Informationssystems kartiert und deren Verteilung statistisch mit einem Einkommensindikator korreliert.

Ergebnisse Im gesamten Untersuchungsraum wurden 67 Points of Sale (PoS) für Fast Food und 41 PoS für Obst und Gemüse identifiziert. Je statusniedriger der Sozialraum, desto besser war das Angebot sowohl ungesunder als auch gesunder Nahrungsmittel.

Schlussfolgerungen Das lokale Fast Food-Angebot stellt einen potenziellen kontextuellen Einflussfaktor auf Adipositas im Sinne von “obesogenic environments” dar.

Disentangling sex allocation in a viviparous reptile with temperature-dependent sex determination: a multifactorial approach

Females are predicted to alter sex allocation when ecological, physiological and behavioural variables have different consequences on the fitness of male and female offspring. Traditionally, tests of sex allocation have examined single causative factors, often ignoring possible interactions between multiple factors. Here, we used a multifactorial approach to examine sex allocation in the viviparous skink, Niveoscincus ocellatus. We integrated a 16-year observational field study with a manipulative laboratory experiment to explore whether the effects of the maternal thermal environment interact with the resources available to females for reproduction to affect sex allocation decisions. We found strong effects of temperature on sex allocation in the field, with females born in warm conditions and males in cold conditions; however, this was not replicated in the laboratory. In contrast, we found no effect of female resource availability on sex allocation, either independently, or in interaction with temperature. These results corresponded with an overall lack of an effect of resource availability on any of the life history traits that we predicted would mediate the benefits of differential sex allocation in this system, suggesting that selection for sex allocation in response to resource availability may be relatively weak. Combined, these results suggest that temperature may be the predominant factor driving sex allocation in this system.

Disrupted cortico-limbic connectivity during reward processing in remitted bipolar I disorder

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.

Positive and Negative Affect as Links Between Social Anxiety and Depression: Predicting Concurrent and Prospective Mood Symptoms in Unipolar and Bipolar Mood Disorders

The co-occurrence of social anxiety and depression is associated with increased functional impairment and a more severe course of illness. Social anxiety disorder is unique among the anxiety disorders in sharing an affective profile with depression, characterized by low levels of positive affect (PA) and high levels of negative affect (NA). Yet it remains unclear how this shared affective profile contributes to the covariation of social anxiety and depressive symptoms. We examined whether self-reported PA and NA accounted for unique variance in the association between social anxiety and depressive symptoms across three groups (individuals with remitted bipolar disorder, type I [BD; n = 32], individuals with remitted major depressive disorder [MDD; n = 31], and nonpsychiatric controls [n = 30]) at baseline and follow-ups of 6 and 12 months. Low levels of PA, but not NA, accounted for unique variance in both concurrent and prospective associations between social anxiety and depression in the BD group; in contrast, high levels of NA, but not PA, accounted for unique variance in concurrent and prospective associations between social anxiety and depression in the MDD group. Limitations include that social anxiety and PA/NA were assessed concurrently and all measurement was self-report. Few individuals with MDD/BD met current diagnostic criteria for social anxiety disorder. There was some attrition at follow-up assessments. Results suggest that affective mechanisms may contribute to the high rates of co-occurrence of social anxiety and depression in both MDD and BD. Implications of the differential role of PA and NA in the relationship between social anxiety and depression in MDD and BD and considerations for treatment are discussed.

True happiness: The role of morality in the folk concept of happiness

Recent scientific research has settled on a purely descriptive definition of happiness that is focused solely on agents' psychological states (high positive affect, low negative affect, high life satisfaction). In contrast to this understanding, recent research has suggested that the ordinary concept of happiness is also sensitive to the moral value of agents' lives. Five studies systematically investigate and explain the impact of morality on ordinary assessments of happiness. Study 1 demonstrates that moral judgments influence assessments of happiness not only for untrained participants, but also for academic researchers and even in those who study happiness specifically. Studies 2 and 3 then respectively ask whether this effect may be explained by general motivational biases or beliefs in a just world. In both cases, we find evidence against these explanations. Study 4 shows that the impact of moral judgments cannot be explained by changes in the perception of descriptive psychological states. Finally, Study 5 compares the impact of moral and nonmoral value, and provides evidence that unlike nonmoral value, moral value is part of the criteria that govern the ordinary concept of happiness. Taken together, these studies provide a specific explanation of how and why the ordinary concept of happiness deviates from the definition used by researchers studying happiness.

Molecular dynamics studies of defect formation during heteroepitaxial growth of InGaN alloys on (0001) GaN surfaces

We investigate the formation of extended defects during molecular-dynamics (MD) simulations of GaN and InGaN growth on (0001) and ([Formula: see text]) wurtzite-GaN surfaces. The simulated growths are conducted on an atypically large scale by sequentially injecting nearly a million individual vapor-phase atoms towards a fixed GaN surface; we apply time-and-position-dependent boundary constraints that vary the ensemble treatments of the vapor-phase, the near-surface solid-phase, and the bulk-like regions of the growing layer. The simulations employ newly optimized Stillinger-Weber In-Ga-N-system potentials, wherein multiple binary and ternary structures are included in the underlying density-functional-theory training sets, allowing improved treatment of In-Ga-related atomic interactions. To examine the effect of growth conditions, we study a matrix of >30 different MD-growth simulations for a range of In _x Ga _1-x N-alloy compositions (0 ≤ x ≤ 0.4) and homologous growth temperatures [0.50 ≤ T/T^*_m (x) ≤ 0.90], where T^*_m (x) is the simulated melting point. Growths conducted on polar (0001) GaN substrates exhibit the formation of various extended defects including stacking faults/polymorphism, associated domain boundaries, surface roughness, dislocations, and voids. In contrast, selected growths conducted on semi-polar ([Formula: see text]) GaN, where the wurtzite-phase stacking sequence is revealed at the surface, exhibit the formation of far fewer stacking faults. We discuss variations in the defect formation with the MD growth conditions, and we compare the resulting simulated films to existing experimental observations in InGaN/GaN. While the palette of defects observed by MD closely resembles those observed in the past experiments, further work is needed to achieve truly predictive large-scale simulations of InGaN/GaN crystal growth using MD methodologies.
