Social resilience: the value of social fitness with an application to the military

Resilience has been regarded narrowly as a quintessential individual property by most investigators. Social resilience, however, is inherently a multilevel construct, revealed by capacities of individuals, but also groups, to foster, engage in, and sustain positive social relationships and to endure and recover from stressors and social isolation. Emergent levels of organization, ranging from dyads, families, and groups to cities, civilizations, and international alliances have long been apparent in human existence, but identifying the features of individuals, relationships, and group structures and norms that promote social resilience-and determining effective interventions to build social resilience-represent some of the most important challenges facing the military as well as contemporary behavioral science. We identify nine personal resources that foster social resilience, and we describe an educational, computer-based program that builds on these resources in an effort to improve the social resilience among troops in the U.S. Army. Data from this program should provide valuable evidence regarding the challenge of building social resilience.     

Family conflict shapes how adolescents take risks when their family is affected

Numerous studies have established that the social context greatly affects adolescent risk taking. However, it remains unexplored whether adolescents' decision‐making behaviors change when they take risks that affect other individuals such as a parent. In the current study, we sought to investigate how the social context influences risky decisions when adolescents' behavior affects their family using a formalized risk‐taking model. Sixty‐three early adolescents (M_age = 13.3 years; 51% female) played a risk‐taking task twice, once during which they could make risky choices that only affected themselves and another during which their risky choices only affected their parent. Results showed that adolescents reporting high family conflict made more risky decisions when taking risks for their parent compared to themselves, whereas adolescents reporting low family conflict made fewer risky decisions when taking risks for their parent compared to themselves. These findings are the first to show that adolescents change their decision‐making behaviors when their risks affect their family and have important implications for current theories of adolescent risk taking.     

Social ties: subgroup differences in costs and benefits

Social ties can be stressful as well as supportive. Are these opposing effects linked, and can they help explain subgroup differences in the efficacy of social support? These questions were applied to data on social support in response to stressful life events. The subjects were 314 women randomly chosen from the registration list of a neighborhood health center in Boston. The data were from the initial interviews of a larger study. The findings include the following: The mobilization of social support was associated with better psychological well-being for women with greater personal resources, but not for those with lower levels of personal resources. Women with lower levels of personal resources were more distressed by life events in the lives of their significant others, especially as the number of these events increased. The subgroup effects of interpersonal support and stress on psychological well-being were independent, separate effects. In sum, women with greater material and psychological resources derived more beneficial support and suffered less stress from their social ties.     

The relations of daily task accomplishment satisfaction with changes in affect: a multilevel study in nurses

Focusing on a sample of nurses, this investigation examined the relationships of daily task accomplishment satisfaction (for direct and indirect care tasks) with changes in positive and negative affect from preshift to postshift. Not accomplishing tasks to one's satisfaction was conceptualized as a daily workplace stressor that should increase daily negative affect and decrease daily positive affect from preshift to postshift. Further, because of the greater centrality of direct care nursing tasks to nursing work role identities (relative to indirect care tasks), we expected that task accomplishment satisfaction (or lack thereof) for these tasks would have stronger effects on changes in affect than would task accomplishment satisfaction for indirect care tasks. We also examined 2 person-level resources, collegial nurse-physician relations and psychological resilience, as moderators of the relationships among these daily variables, with the expectation that these resources would buffer the harmful effects of low task accomplishment satisfaction on nurse affect. Results supported almost all of the proposed effects, though the cross-level interactions were observed only for the effects of indirect care task accomplishment satisfaction on affect and not for direct care task accomplishment satisfaction on affect.     

情感启发式对风险选择的影响

本研究旨在考察情感启发式对风险选择的影响。研究1采用线上和线下结合的方式对687名大学生进行问卷施测,修订并检验中文版情感启发式问卷的信效度,以该问卷测试的风险−收益相关系数作为衡量情感启发式倾向的指标。研究2采用极端被试法,在103名大学生完成问卷后,将风险−收益相关系数绝对值前20%和后20%的被试分为高、低情感启发式组,完成风险选择任务。结果发现：（1）中文版情感启发式问卷具有较好的信度与效度,可以作为情感启发式倾向的测试问卷。（2）风险选择任务激活负性情绪时,相比于低情感启发式倾向,高情感启发式倾向的被试更容易受负性情绪的影响,其风险判断的主观值更高。研究揭示了情感启发式对风险选择的影响,为情感启发式作为个体进行风险判断的重要依据提供了实证支持。     

A Brief Gratitude Writing Intervention Decreased Stress and Negative Affect During the COVID-19 Pandemic

Exploring ways to mitigate the stress of the COVID-19 pandemic is important for long-term health. Expressive and gratitude-focused writing are effective methods to help individuals process traumatic or stressful events. Gratitude-focused writing may yield additional benefits because it helps individuals appraise events positively. We hypothesized that an online gratitude writing intervention would yield greater benefits than an expressive writing intervention or control group. Participants were randomized to one of three groups and completed assessments one-week and one-month post-intervention. The gratitude writing group maintained gratitude levels and decreased stress and negative affect at one-month post-intervention. The expressive writing group decreased in gratitude and showed no changes in stress or negative affect at one-month post-intervention. The control group decreased in gratitude and negative affect and showed no changes in stress at one-month post-intervention. Gratitude writing may be a better resource for dealing with stress and negative affect than traditional expressive writing methods under extremely stressful situations with uncertain trajectories.

     

Resilient individuals use positive emotions to bounce back from negative emotional experiences

Theory indicates that resilient individuals "bounce back" from stressful experiences quickly and effectively. Few studies, however, have provided empirical evidence for this theory. The broaden-and-build theory of positive emotions (B. L. Fredrickson, 1998, 2001) is used as a framework for understanding psychological resilience. The authors used a multimethod approach in 3 studies to predict that resilient people use positive emotions to rebound from, and find positive meaning in, stressful encounters. Mediational analyses revealed that the experience of positive emotions contributed, in part, to participants' abilities to achieve efficient emotion regulation, demonstrated by accelerated cardiovascular recovery from negative emotional arousal (Studies 1 and 2) and by finding positive meaning in negative circumstances (Study 3). Implications for research on resilience and positive emotions are discussed.     

A dynamic,self-regulatory model of affect and performance: Interactions between states,traits and task demands

State–trait consistency and valence principles were integrated within a dynamic self-regulatory framework to predict interactive effects of state affect, trait affect and task demands on performance. State affect and performance were measured repeatedly as individuals completed a complex and dynamic decision-making task. Task demands were manipulated at the within-person level. The beneficial effect of state positive affect was strongest for individuals with high trait positive affect; however this effect was only evident under high task demands. The detrimental effect of state negative affect was weakest for individuals with high trait negative affect, with this effect being constant across task demand levels. This study demonstrated that state–trait inconsistency can be bad for individuals with high trait positive affect and consistency can be good for individuals with high trait negative affect.     

Using cognitive models to map relations between neuropsychological disorders and human decision-making deficits

Findings from a complex decision-making task (the Iowa gambling task) show that individuals with neuropsychological disorders are characterized by decision-making deficits that lead to maladaptive risk-taking behavior. This article describes a cognitive model that distills performance in this task into three different underlying psychological components: the relative impact of rewards and punishments on evaluations of options, the rate that the contingent payoffs are learned, and the consistency between learning and responding. Findings from 10 studies are organized by distilling the observed decision deficits into the three basic components and locating the neuropsychological disorders in this component space. The results reveal a cluster of populations characterized by making risky choices despite high attention to losses, perhaps because of difficulties in creating emotive representations. These findings demonstrate the potential contribution of cognitive models in building bridges between neuroscience and behavior.     

The forest and the trees: Examining the association of self-compassion and its positive and negative components with psychological functioning

ABSTRACT

This paper presents two studies focusing on the link between psychological functioning and self-compassion as measured by the Self-Compassion Scale (SCS), especially in terms of SCS components that represent increased compassionate and reduced uncompassionate behavior. Study One examined this association in seven domains – psychopathology, positive psychological health, emotional intelligence, self-concept, body image, motivation, and interpersonal functioning – and found that while reduced negative self-responding had a stronger link to negative emotionality and self-evaluation than positive self-responding, they were roughly equivalent predictors in other domains. Study Two examined the association of compassionate and reduced uncompassionate behavior with sympathetic nervous system and inflammatory activity after stress, and found they equally predicted salivary alpha amylase and interleukin-6 levels in individuals after a stressful situation. Overall, results suggest that both compassionate and reduced uncompassionate self-responding are central to self-compassion and that both help to explain its link to healthy psychological functioning.     

Resilience as positive coping appraisals: Testing the schematic appraisals model of suicide (SAMS)

Aims

The Schematic Appraisals Model of Suicide (SAMS) suggests that positive self-appraisals may be important for buffering suicidal thoughts and behaviours, potentially providing a key source of resilience. The current study aimed to explore whether positive self-appraisals buffered individuals from suicidality in the face of stressful life events.

Method

78 participants who reported experiencing some degree of suicidality were recruited from a student population. They completed a battery of questionnaires including measures of suicidality, stressful life events and positive self-appraisals.

Results

Positive self-appraisals moderated the association between stressful life events and suicidality. For those reporting moderate or high levels of positive self-appraisals, raised incidence of stressful life events did not lead to increases in suicidality.

Discussion

These results support the SAMS framework, and suggest that positive self-appraisals may confer resilience to suicide. Positive self-appraisals may be a promising avenue for further resilience research, and an important area to target for suicide interventions.     

The effects of discussion on group and individual choices among bets

The effects of discussion on subsequent group and individual choices are studied in a situation where subjects choose between a sure gain of varying amount and five probability levels associated with larger gains of expected value equal to that of the sure gain. At the end of the experiment, a single bet, chosen at random, is played for money. Before discussion, subjects have to guess the percentage of similar, more risky and more cautious choices made by their peers for each of the six bets. As predicted by a majority-rule decision-making model significant risky shifts were observed for relatively low values of sure gain. For higher values, however, groups tended to be more cautious than individuals. The final private choices of individuals were significantly more risky than their initial decisions. Most individuals apparently thought they were at least as risky as most others. This finding was due, however, primarily to the responses of subjects who chose the highest risk-level (the ceiling effect) and, secondly, to the consistent tendency of most individuals to guess that others make the same choices as they themselves. It is concluded that majority influence seems a satisfactory explanation of group risky shifts observed in the present study, but it cannot account for modifications of group and individual choices in all risk-taking situations.     

La résilience et le bien-être psychologique au travail au service de la thèse du travailleur heureux-productif

Based on broaden-and-build theory, this study proposes to expand the happy-productive worker thesis by exploring an emergent operationalization of happiness. To do so, the mediating effect of the dimensions of psychological well-being at work (i.e., relation to oneself, to others and to work) on the relation between resilience and task performance has been tested. A total of 280 Quebec workers filled out validated measures. Obtained by structural equation modelling analyses, the results indicate that the rapport with oneself of psychological well-being at work acts as the only mediator between resilience and task performance. These findings underscore the importance of encouraging the development of interventions that build on the resilience and positive experience of workers to optimize their work performance.     

Multiple racial identities as sources of psychological resilience

Much of the research on multiracial individuals has focused on the impact of a multiracial background on psychological well‐being. This work, often using clinical samples, identified a higher prevalence of negative psychological outcomes among multiracial individuals, such as low self‐esteem, poor grades, or self‐hatred, and has emphasized that these negative outcomes stem from the unique challenges associated with navigating multiple racial identities. However, research on nonclinical samples finds that multiracial individuals fare as well as monoracial individuals on these, and other, outcomes. We put forth a synthesizing theory aimed at understanding how multiracial individuals develop adaptive coping strategies, which help them learn to navigate multiple identities and maintain positive psychological outcomes. In the current contribution, we build on existing research to theorize that multiracial individuals can engage in two psychological strategies that increase resilience: (a) switching between multiple racial identities and (b) reduced essentializing of race. Evidence and consequences of these two strategies are discussed. Taken together, in contrast to traditional depletion models of coping, this work highlights the unique experience of multiracial individuals and the potential psychological benefits of belonging to multiple racial groups in a racialized world.

Losses Induce Consistency in Risk Taking Even Without Loss Aversion

It is posited that because of the attentional effect of losses, individuals would show more behavioral consistency in risk‐taking tasks with losses, even in the absence of loss aversion. In two studies, the consistency of risky choices across different experience‐based tasks was evaluated for gain, loss, and mixed (gain loss) tasks. In both studies, losses facilitated the consistency across tasks: the correlation between risk‐taking choices in different tasks increased when the tasks involved frequent losses. Study 2 also showed a positive effect of losses on temporal consistency. Losses increased the correlation between risk‐taking levels across two sessions that were 45 days apart. Also in Study 2, losses induced consistency between experiential risk‐taking choices and self‐reported ratings of risky behavior. In both studies, the positive effect of losses on consistency was observed even when the average participant did not exhibit loss aversion. Taken together, the results indicate that losses increase the consistency of risk‐taking behavior and suggest that this is due to the effect of losses on attention.

Loss, trauma, and human resilience: have we underestimated the human capacity to thrive after extremely aversive events?

Many people are exposed to loss or potentially traumatic events at some point in their lives, and yet they continue to have positive emotional experiences and show only minor and transient disruptions in their ability to function. Unfortunately, because much of psychology's knowledge about how adults cope with loss or trauma has come from individuals who sought treatment or exhibited great distress, loss and trauma theorists have often viewed this type of resilience as either rare or pathological. The author challenges these assumptions by reviewing evidence that resilience represents a distinct trajectory from the process of recovery, that resilience in the face of loss or potential trauma is more common than is often believed, and that there are multiple and sometimes unexpected pathways to resilience.
