Healthy sleep durations appear to vary across cultures

Past research finds that sleep duration is reliably linked with health yet sleep durations differ substantially between countries. We investigated whether countries with shorter sleep durations have worse health. Study 1 analyzed national sleep durations from 14 past investigations (k = 353) and found that they were not associated with national health. Study 2 collected sleep duration and health data from people from 20 different countries (N = 4,933). Average sleep durations varied substantially between countries (range = 1.57 h). A quadratic relation between sleep duration and health was found in all countries, although the turning points varied between countries. Individuals whose sleep duration was closer to their country's perceived ideal reported better health. The results suggest that the amount of sleep associated with optimal health varies across countries.

The role of hope in college transition: Its cross-lagged relationships with psychosocial resources and emotional well-being in first-year college students

INTRODUCTION

College transition is often regarded as the most stressful phase of life by college students. Hence, it is necessary to find ways to help them adjust more smoothly to this transition. Hope, as conceptualized by C. R. Snyder, has been widely studied as a predictor of optimal functioning and has been shown to be associated with better adjustment among college students. This study aimed to shed light on the role of hope in college transition by examining its unique reciprocal relationships with an array of important psychosocial resources and emotional well-being among first-year college students.

METHODS

Data were collected from a sample of Hong Kong college freshmen (N = 433, Medianage = 18 years old, 63.7% female) at two time points. At each time point, participants completed self-reported measures tapping into their levels of hope, psychosocial resources, and emotional well-being. Psychological resources included general and academic self-efficacy, meaning in life, and optimism. Social resources included secure attachment, perceived school environment, and social support. Emotional well-being was operationalized as positive and negative emotions. Cross-lagged panel models were constructed and tested by path analyses.

RESULTS

When autoregression and the effects of other variables were controlled, a greater sense of hope uniquely predicted higher levels of general and academic self-efficacy, greater presence of life meanings, more secure attachment, and more positive and fewer negative emotions. On the other hand, higher levels of meaning in life (both presence and search) and social support uniquely predicted greater hope. Academic hope and presence of life meanings reciprocally predicted one another, whereas other significant cross-lagged relationships were unidirectional.

CONCLUSIONS

The findings suggest interventions that promote hope can be useful in helping college freshmen adjust to the new college environment by enhancing their psychosocial resources and emotional well-being. Such interventions would be more effective if they included elements that boost meaning in life and social support, which are expected to further enhance the perceptions of hope.

Temporal Orientation and the Association Between Adverse Life Events and Internalizing Symptoms in Vietnamese American and European American Adolescents

Adverse life events are associated with greater internalizing symptoms. However, prior research has identified cross-cultural variation in whether and to what extent factors amplify or buffer the impact of these stressors. Broadly defined as the tendency to focus on past, present, or future events, temporal orientation is a dispositional factor that is culturally influenced and may explain variance in internalizing symptoms following adverse events. Cultural congruence, or the degree to which a factor is considered normative in an individual's culture, may be an important explanation of variation in levels of risk. The current study examines how culturally congruent temporal orientation differentially impacts the relation between adverse life events and internalizing symptoms in a longitudinal sample of 10th and 11th grade Vietnamese American (n = 372) and European American adolescents (n = 304). Results indicated that Vietnamese American adolescents endorsed significantly higher levels of past and present, but not future, temporal orientation compared to European American adolescents. Among both Vietnamese and European American adolescents, past temporal orientation was positively associated with internalizing symptoms and adverse life events. Findings also demonstrated that the influence of present temporal orientation on the relation between adverse life events and internalizing symptoms was further moderated by ethnicity, such that present temporal orientation buffered risk for negative outcomes among European Americans but not Vietnamese Americans. These data highlight the importance of measuring and testing specific dimensions of culturally relevant processes when considering responses to adverse life events.

Valuing Negative Affect Weakens Affect-Health Linkages: Similarities and Differences Across Affect Valuation Measures

Negative affect (NA) has been robustly linked to poorer psychological health, including greater depressive symptoms, personal burnout, and perceived stress. These associations, known as affect-health links, have been postulated by our research team to vary with different levels of negative affect valuation (NAV), such that people who evaluate NA states as more pleasant, helpful, appropriate, and/or meaningful may show weaker affect-health links. Another affect valuation construct is ideal NA, which is the degree to which people ideally want to experience NA states (i.e., desirability of affective states). The current study extends previous research by examining these two different measures of affect valuation (NAV and ideal NA) and comparing the extent to which they moderate affect-health links for psychological health and functioning. Participants from the Health and Daily Experiences (HEADE) study (N = 162 comprising of 56 younger adults and 106 older adults) completed questionnaires in a laboratory setting and ecological momentary assessments of NA 6 times a day for 7 consecutive days (i.e., trait NA). The results demonstrated that the two affect valuation constructs were distinct and showed different patterns of buffering effects. NAV attenuated the association between trait NA and depressive symptoms, personal burnout, and intolerance of uncertainty. Ideal NA attenuated affect-health links for depressive symptoms and perceived stress. These findings point to the importance of sharpening the distinctions between various affect valuation constructs to elucidate their unique contributions to attenuating affect-health links.

Show me your friends, I'll tell you your emotions: Emotional fit of immigrant-origin minority youth in cross-cultural friendship networks

The typical emotional responses to certain types of situations differ across cultures. Being reprimanded by your teacher in front of the class may be cause for anger and indignation among pupils in one cultural context, but for anger, shame, and possibly respect for the teacher among pupils in another cultural context. The consequence for immigrant-origin minorities is that they may not fit the emotions of the majority culture. Previous research has found that minorities who have majority contact have higher emotional fit with the majority culture. In the current study, we suggest that friendships with majority peers are particularly important to minorities' emotional fit. Students (945 minority and 1256 majority) from a representative sample of Belgian middle schools completed a sociometric questionnaire on their classroom friendships and rated their emotional experiences in two situations. Multilevel models yielded higher levels of emotional fit for minority youth with many (vs. few) majority friends as well as for minorities whose majority friends are connected (vs. less connected) to each other, or who are well-connected in the majority peer network. Having majority friends predicted emotional fit over and above majority contact in general.

Considerations for Advancing the Conceptualization of Well-being

In this commentary, we raise several points regarding Park and colleagues' emotional well-being framework. First, we question whether the term emotional well-being is appropriate and whether a new framework is necessary, and we argue that the field may be better served through other efforts, such as clarifying the distinctions between different well-being constructs and providing guidance on best practices for measurement and intervention. In addition, we note that by placing well-being on the opposite end of the spectrum from despair and depression, Park and colleagues have overlooked the influences of stress, distress, and life challenges on shaping positive aspects of well-being, and vice versa. Furthermore, we challenge the conceptualization of well-being as encompassing how positive an individual feels generally and about life overall. In its current form, this definition of well-being is overly static and trait-like, whereas a process-oriented conceptualization would more closely align with how well-being unfolds in real-life contexts and would be more suitable for identifying mechanistic targets for intervention. Finally, we raise the concern that the process for developing this definition of well-being did not actively involve input from diverse communities that have historically been disserved and underrepresented in research, practice, and policy. The cultural differences in constituents of well-being as well as evidence demonstrating that key positive psychological constructs (e.g., positive affect, sense of control) are less health-protective in racial/ethnic minorities than in whites necessitate greater integration of perspectives from underrepresented communities to build a more inclusive and accurate understanding of well-being.

Associations Between Emotion Regulation and Life Satisfaction Among University Students From Germany, Hong Kong, and Japan: The Mediating Role of Social Support

The social adaptiveness of emotion regulation (ER) may differ across cultures due to different social values for the experience and expression of emotions. Specifically, suppression might disrupt social interactions among Germans, but not among Hong Kong Chinese (HKC) and Japanese, due to an emphasis on self-expression and authenticity in Western cultures. In the present study, we examined cultural differences in associations of ER strategies with life satisfaction and social support. Extending prior research, we also test whether social support functions as a mediator for relationships between ER strategies and life satisfaction within cultural groups. University students from Germany (N = 148), Hong Kong (N = 125), and Japan (N = 127) participated in our online survey. Moderation analyses revealed that suppression was related to lower life satisfaction and less social support among Germans, but not among HKC nor Japanese. Social support completely mediated the negative relationship between suppression and life satisfaction among Germans. Furthermore, for Germans and HKC, social support partially mediated the positive relationship between reappraisal and life satisfaction, and the negative relationship between rumination and life satisfaction. Our findings suggest that cultural differences in the associations between ER and well-being might be largely explained by the differential effect of ER strategies on social functioning and adaptation in the respective cultural context.

Culture and Health: Recent Developments and Future Directions 1

Evidence of cultural differences in relationships and emotions has accumulated over the past few decades. As findings on cultural differences in psychological processes have accumulated, there has been growing interest in investigating whether they have implications for other phenomena such as health. Using scientific advances from the MIDUS and MIDJA studies, both publicly available, we examine links between culture and health. We first briefly review the accumulated evidence on cultural influences on health correlates of psychosocial factors. We then feature two recent developments - a more micro-level perspective on biological factors that may be involved in the culture and health linkage, and a more macro-level view of socioeconomic inequality, which also matters for health. Both perspectives inform the pathways through which health effects occur. Finally, we conclude our review by highlighting the changing historical contexts surrounding these cross-cultural investigations. Specifically, we draw attention to widening of economic inequality across cultures and the world-wide COVID-19 pandemic. These happenings bring notable implications for future research on health across cultural contexts.

Considering cross-cultural differences in sleep duration between Japanese and Canadian university students

Sleep is a fundamental biological process that all humans exhibit, and there is much evidence that people suffer adverse health outcomes from insufficient sleep. Despite this evidence, much research demonstrates significant heterogeneity in the amounts that people sleep across cultures. This suggests that despite serving fundamental biological functions, sleep is also subject to cultural influence. Using self-report and actigraphy data we examined sleep among European Canadian, Asian Canadian, and Japanese university students. Significant cultural differences emerged in terms of various parameters of sleep (e.g. sleep time), and beliefs about sleep (e.g. perceived relation between sleep and health). Despite sleeping significantly less than European Canadians, Japanese participants slept less efficiently, yet reported being less tired and having better health. Moreover, relative to European Canadians, Japanese participants perceived a weaker relation between sleep and physical health, and had a significantly shorter ideal amount of sleep. Asian Canadians’ sleep behaviors and attitudes were largely similar to European Canadians suggesting that people acculturate to local cultural sleep norms.

Cultural Scripts of Traumatic Stress: Outline, Illustrations, and Research Opportunities

As clinical-psychological scientists and practitioners increasingly work with diverse populations of traumatized people, it becomes increasingly important to attend to cultural models that influence the ways in which people understand and describe their responses to trauma. This paper focuses on potential uses of the concept of cultural script in this domain. Originally described by cognitive psychologists in the 1980s, scripts refer to specific behavioral and experiential sequences of elements such as thoughts, memories, attention patterns, bodily sensations, sleep abnormalities, emotions and affective expressions, motivation, coping attempts, and ritualized behaviors that are relevant to posttraumatic adjustment. We differentiate between experiences of traumatic stress that are scripted (e.g., cultural explanations are available) versus unscripted. Further characteristics such as script tracks, the effect of script interruptions, and contextual fit of scripts with other cultural models are also described. We consider examples of traumatic stress associated with war and organized, sexualized violence from "Western" and "non-Western" world regions. The concluding part of this review describes a number of possibilities for methodological approaches to assessment of cultural scripts. Capturing central elements of the script(s) of trauma would aid psychological researchers and clinicians in understanding the experiences of trauma in cultural context, which could ultimately lead to better clinical service opportunities worldwide.

Subjective health in relation to hedonic and eudaimonic wellbeing: Evidence from the Gallup World Poll

This study investigated the relationships between subjective health, hedonic wellbeing (i.e. positive affect, negative affect, and life satisfaction), and eudaimonic wellbeing (i.e. psycho-social functioning). The sample was drawn from the Gallup World Poll and included a total of 1,567,295 individuals in 165 countries. We found that both hedonic and eudaimonic wellbeing were uniquely associated with subjective health. However, the relative contributions of each dimension to subjective health varied, with negative affect demonstrating the strongest relationship with subjective health and life satisfaction demonstrating the weakest association. The moderating effects of some national-level variables were also explored.
