Emergent research identifies cultural tightness-looseness as an important factor for understanding cross-national outcome differences during the coronavirus pandemic. Because perceived tightness-looseness can be measured as an individual-level difference rather than a nation-level difference, and because tightness-looseness may shift during large-scale crises, we investigated whether such shifts occurred early in the coronavirus pandemic in both China (a relatively tight nation, n = 3642) and the U.S. (a relatively loose nation, n = 3583) across three cohorts. Tightness increased across cohorts in China and reduced across cohorts in the U.S. These changes transmitted corresponding indirect effects whereby compliance and institutional trust (scientific and government) about the pandemic were increased in China across cohorts, but decreased in the U.S. across cohorts. These patterns extend advice that national governments can increase compliance and trust via “tightening” by cautioning against norm-setters signaling the reverse (that norms about compliance are loose) given the outcomes observed in the U.S. samples. 相似文献

This study examined, in a sample of recently immigrated Hispanic adolescents in Miami and Los Angeles, the extent to which bicultural identity integration (BII; involving the ability to synthesise one's heritage and receiving cultural streams and to identify as a member of both cultures) is best understood as a developmental construct that changes over time or as an individual‐difference construct that is largely stable over time. We were also interested in the extent to which these trajectories predicted mental health and family functioning. Recent‐immigrant 9th graders (N = 302) were assessed 6 times from 9th to 12th grade. Latent class growth analyses using the first 5 timepoints identified 2 trajectory classes—one with lower BII scores over time and another with higher BII scores over time. Higher heritage and US identity at baseline predicted membership in the higher BII class. At the 6th study timepoint, lower BII adolescents reported significantly poorer self‐esteem, optimism, prosocial behaviour and family relationships compared with their higher BII counterparts. These findings are discussed in terms of further research on the over‐time trajectory of biculturalism, and on the need to develop interventions to promote BII as a way of facilitating well‐being and positive family functioning. 相似文献

Parenting and family interventions have repeatedly shown effectiveness in preventing and treating a range of youth outcomes. Accordingly, investigators in this area have conducted a number of studies using statistical mediation to examine some of the potential mechanisms of action by which these interventions work. This review examined from a methodological perspective in what ways and how well the family-based intervention studies tested statistical mediation. A systematic search identified 73 published outcome studies that tested mediation for family-based interventions across a wide range of child and adolescent outcomes (i.e., externalizing, internalizing, and substance-abuse problems; high-risk sexual activity; and academic achievement), for putative mediators pertaining to positive and negative parenting, family functioning, youth beliefs and coping skills, and peer relationships. Taken as a whole, the studies used designs that adequately addressed temporal precedence. The majority of studies used the product of coefficients approach to mediation, which is preferred, and less limiting than the causal steps approach. Statistical significance testing did not always make use of the most recently developed approaches, which would better accommodate small sample sizes and more complex functions. Specific recommendations are offered for future mediation studies in this area with respect to full longitudinal design, mediation approach, significance testing method, documentation and reporting of statistics, testing of multiple mediators, and control for Type I error. 相似文献

The goal of the study was to examine the dimensionality of the Career Decision Self-Efficacy Scale Short Form (CDSES-SF, Betz et al. 1996). Integrating several previous findings from different cultures, we found that the bifactor structure of the CDSES-SF on a Hungarian sample of 649 respondents showed the best model fit. This structure includes a general CDSE factor covering 15 items and the original five specific factors (self-appraisal, occupational information, goal selection, planning, and problem solving) covering three items each. This short form of CDSES shows an acceptable model fit and appropriate reliability in terms of the Cronbach’s alpha and omega values. Regarding career decision self-efficacy, a large proportion of variance was explained by the general factor and to a smaller extent by the specific factors. These results can be considered as a first step in resolving the paradox of the dimensionality of CDSES-SF. 相似文献

This study investigated how various risk and protective factors interface with child health and well-being at the population level. Specifically, we examined the association of income, social-contextual variables, and indicators of health-related habits and activities to children’s life satisfaction and perceived overall health. Child data were collected via a self-report survey, the Middle Years Development Instrument, which was administered in three demographically diverse Canadian school districts to 5026 grade 4 students (83 % of the students had complete data and were included in the analyses). Multiple regression and mediation analyses were conducted to examine the joint associations of social relationships with adults and peers, nutrition and sleep habits, and after school sports activities with children’s satisfaction with life and perceived health. Results indicate that peer belonging and relationships with adults at home and school were the strongest predictors of life satisfaction. Furthermore, the (small) association between income and life satisfaction was mediated by social relationship variables. Child reports of perceived health were predicted by peer belonging, adult relationships (home, school, neighborhood), after-school team sports, and nutrition habits. The (small) association between income and health was mediated by social relationships and team sports participation. Findings are discussed in light of previous research on social determinants and socio-economic gradients of children’s health and life satisfaction. 相似文献

Previous fMRI studies have reported mixed evidence for the influence of selective attention on amygdala responses to emotional
stimuli, with some studies showing “automatic” emotional effects to threat-related stimuli without attention (or even without
awareness), but other studies showing a gating of amygdala activity by selective attention with no response to unattended
stimuli. We recorded intracranial local field potentials from the intact left lateral amygdala in a human patient prior to
surgery for epilepsy and tested, with a millisecond time resolution, for neural responses to fearful faces appearing at either
task-relevant or task-irrelevant locations. Our results revealed an early emotional effect in the amygdala arising prior to,
and independently of, attentional modulation. However, at a later latency, we found a significant modulation of the differential
emotional response when attention was directed toward or away from fearful faces. These results suggest separate influences
of emotion and attention on amygdala activation and may help reconcile previous discrepancies concerning the relative responsiveness
of the human amygdala to emotional and attentional factors. 相似文献

Individuals with psychopathy are often characterized by emotional processing deficits, and recent research has examined the specific contexts and cognitive mechanisms that underlie these abnormalities. Some evidence suggests that abnormal features of attention are fundamental to emotional deficits in persons with psychopathy, but few studies have demonstrated the neural underpinnings responsible for such effects. Here, we use functional neuroimaging to examine attention–emotion interactions among incarcerated individuals (n = 120) evaluated for psychopathic traits using the Hare Psychopathy Checklist–Revised (PCL-R). Using a task designed to manipulate attention to emotional features of visual stimuli, we demonstrate effects representing implicit emotional processing, explicit emotional processing, attention-facilitated emotional processing, and vigilance for emotional content. Results confirm the importance of considering mechanisms of attention when evaluating emotional processing differences related to psychopathic traits. The affective-interpersonal features of psychopathy (PCL-R Factor 1) were associated with relatively lower emotion-dependent augmentation of activity in visual processing areas during implicit emotional processing, while antisocial-lifestyle features (PCL-R Factor 2) were associated with elevated activity in the amygdala and related salience network regions. During explicit emotional processing, psychopathic traits were associated with upregulation in the medial prefrontal cortex, insula, and superior frontal regions. Isolating the impact of explicit attention to emotional content, only Factor 1 was related to upregulation of activity in the visual processing stream, which was accompanied by increased activity in the angular gyrus. These effects highlight some important mechanisms underlying abnormal features of attention and emotional processing that accompany psychopathic traits. 相似文献

Before alcohol was generally known to cause birth defects, NIAAA in 1974 began funding a population-based Seattle study on
alcohol use and pregnancy outcome. Women receiving prenatal care by mid-pregnancy were recruited (N = 1,529) and interviewed at home. Approximately 500 offspring exposed to a range of alcohol levels were examined on 11 occasions
between day 1 and 25 years. Neuropsychological and neurobehavioral performance measures are correlated with prenatal alcohol
dose, without substantial confounding by socio-demographic or rearing conditions, smoking, nutrition, or other drugs. Deficits
in attention, arithmetic skill, spatial-visual memory, and IQ, as well as increased alcohol problems and psychiatric disorders
are among offspring outcomes correlated at several ages with maternal drinking during and before pregnancy recognition. Findings
are not confined to women who believed they had alcohol problems. Not all exposed offspring appear affected. 相似文献

This study investigated factors associated with social anxiety during early adolescence using multiple informants, including
self and peer perspectives, teacher ratings, and direct observations. Negative social performance expectations, maladaptive
coping strategies, and social skill deficits were examined as correlates of social anxiety and mediators linking social anxiety
with poor peer relations. Participants were 84 middle school students (47 girls, 37 boys) over-sampled for elevated social
anxiety. Analyses revealed correlations linking social anxiety with decreased peer acceptance and increased peer victimization.
Path analysis indicated that negative social performance expectations and social withdrawal-disengagement accounted for the
association between social anxiety and decreased peer acceptance. Social anxiety, self-directed coping strategies, and social
withdrawal-disengagement were each directly linked with increased peer victimization for boys. The results replicate findings
based on clinical samples, extend understanding of cognitive, social, and behavioral factors associated with social anxiety
in middle school, and provide new information regarding gender differences in the correlates of social anxiety. 相似文献
