Nightly Sleep Predicts Next-Morning Expectations for Stress and Positive Experiences.

OBJECTIVE: Abundant research has linked nightly sleep as an antecedent of daily psychosocial experiences; however, less is known about sleep's influence on daily expectations of these experiences. Therefore, this research examined the day-to-day associations of sleep quality, duration, and efficiency with next-day expectations for stress(ors) and positive experiences, as well as whether these expectations were related to end-of-day reports of physical symptoms. METHODS: In Study 1, U.S. adults ( n = 354; ages 19 to 74) completed twice-daily diaries for 10 weekdays about sleep, expectations for encountering daily stressors and positive events, and physical symptoms. In Study 2, adults in Canada ( n = 246; ages 25 to 87) wore a sleep watch for 14 consecutive days and completed mobile surveys 5×/day about sleep, stressfulness and pleasantness expectations, and physical symptoms. RESULTS: Multilevel models indicated that self-reported sleep quality and duration, but not efficiency, were associated with lower next-day expectations for stressors (Study 1) and stressfulness (Study 2). Self-reported sleep quality (Study 1) and all sleep indices (Study 2) predicted greater next-day expectations for positive events and pleasantness, respectively. For actigraphy-assessed sleep (Study 2), only longer-than-usual actigraphic sleep duration was associated with lower stressfulness expectations, whereas both sleep duration and efficiency were positively linked with daily pleasantness expectations. Only pleasantness expectations (Study 2)-but not daily stressfulness and event expectations (Study 1)-predicted end-of-day physical symptoms. CONCLUSION: Findings suggest the importance of sleep on expectations of next-day stress and positive experiences, of which may have implications for daily physical health.

Positive event diversity: Relationship with personality and well-being.

OBJECTIVE: Examining the personality and well-being correlates of positive event diversity. BACKGROUND: Past research has highlighted that personality traits are linked to the frequency of daily positive events. This study is the first to examine positive event diversity, the extent to which positive events are spread across multiple types of positive life domains, as well as its personality and well-being correlates. METHOD: We conducted parallel analyses of three daily diary datasets (Ns = 1919, 744, and 1392) that included evening assessment of daily positive events and affective well-being. The Big Five personality traits were assessed in baseline surveys. RESULTS: Positive Event Diversity was related to higher person-mean daily positive affect but not negative affect. Higher Extraversion, Agreeableness, Openness, and lower Neuroticism were correlated with more positive event diversity. These associations became nonsignificant when controlling for positive event frequency. Positive event frequency moderated the link between positive event diversity and person-mean affect, such that higher positive event diversity was associated with higher negative and lower positive affect for people who experienced more frequent positive events. CONCLUSIONS: No consistent evidence was found for personality as a moderator of the positive event diversity-well-being link across the three studies. Further, the well-being implications of positive event diversity may be better understood when interpreting them alongside indexes of positive event frequency.

Cultural stress and immigrant well-being: The role of sense of purpose.

OBJECTIVES: Immigrants face multiple forms of cultural stress that hold pernicious influences on their psychological well-being, including everyday discrimination, bicultural stressors, and negative context of reception from others. Research thus is needed to consider potential buffers and mitigating factors that may help immigrant adults in the face of cultural stress. The present studies evaluated a sense of purpose as one potential buffer. METHOD: Study 1 asked immigrant adults in the Unites States to complete measures of the three cultural stress indicators in addition to sense of purpose and measures of well-being (depressive symptoms, anxiety, stress, self-esteem, self-rated health). Multiple regression analyses examined whether sense of purpose moderated the influence of cultural stress on immigrant well-being. Study 2 randomly assigned immigrant participants receive an experimental condition that asked participants to imagine a common cultural stressor faced by immigrants. Multiple regression analyses tested whether sense of purpose operated differently on postscenario affect across the control and experimental conditions. RESULTS: Study 1 found that all cultural stress indicators negatively correlated with psychological well-being and sense of purpose. However, sense of purpose did not significantly moderate these associations. Study 2 found that imagining the cultural stressor led to worse momentary affective well-being, whereas sense of purpose was associated with better well-being. Again, sense of purpose did not interact with the condition to predict the postscenario affect. CONCLUSIONS: Sense of purpose was consistently associated with better psychological well-being. However, little evidence was found that sense of purpose mitigates the ill effects of cultural stress for immigrant adults. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Negative Emotional Reactivity and Somatic Symptoms during Adolescence Predict Adult Health and Wellbeing in Early and Middle Adulthood.

Longitudinal research is lacking with respect to how negative emotional reactivity and somatic symptoms during adolescence set the stage for later health. The aim of this longitudinal study was to examine within-person associations between negative emotional reactivity and somatic symptoms during adolescence and their effects on health and wellbeing in adulthood. Participants (N = 1527; 48.3% female) were assessed annually at the age of 12 to 16 years and at the age of 35 and 45 years. Adolescents with frequent somatic symptoms reported higher reactivity. Individual differences in levels and changes of somatic symptoms and reactivity were independently associated with adult health and wellbeing decades later. The findings underscore the importance of considering how individual differences change during adolescent development.

A Phenome-Wide Association Study (PheWAS) of Late Onset Alzheimer Disease Genetic Risk in Children of European Ancestry at Middle Childhood: Results from the ABCD Study.

Genetic risk for Late Onset Alzheimer Disease (AD) has been associated with lower cognition and smaller hippocampal volume in healthy young adults. However, whether these and other associations are present during childhood remains unclear. Using data from 5556 genomically-confirmed European ancestry youth who completed the baseline session of the ongoing the Adolescent Brain Cognitive DevelopmentSM Study (ABCD Study®), our phenome-wide association study estimating associations between four indices of genetic risk for late-onset AD (i.e., AD polygenic risk scores (PRS), APOE rs429358 genotype, AD PRS with the APOE region removed (ADPRS-APOE), and an interaction between ADPRS-APOE and APOE genotype) and 1687 psychosocial, behavioral, and neural phenotypes revealed no significant associations after correction for multiple testing (all ps > 0.0002; all pfdr > 0.07). These data suggest that AD genetic risk may not phenotypically manifest during middle-childhood or that effects are smaller than this sample is powered to detect.

Associations for Sense of Purpose with Smoking and Health Outcomes Among Adults with Diabetes.

BACKGROUND: Health complications from diabetes place major strain on individuals, financially and emotionally. The onset and severity of these complications are largely driven by patients' behaviors, making psychosocial factors that influence behaviors key targets for interventions. One promising factor is sense of purpose or the degree to which a person believes their life has direction. METHOD: The current study investigated whether sense of purpose predicts self-rated health, cardiovascular disease, and smoking status among adults with diabetes concurrently and prospectively. Moreover, it tested whether these associations held across multiple samples and cultures. Coordinated analysis using 12 datasets cross-sectionally and eight longitudinally (total N = 7277) estimated the degree to which sense of purpose is associated with subjective health, smoking status, and cardiovascular disease among adults with diabetes. Coordinated analysis allows for greater generalizability of results across cultures, time periods, and measurement instruments. Datasets were included if they concurrently included a measure of sense of purpose and diabetes status and at least one health measure: self-rated health, current smoking status, or heart condition status. RESULTS: Sense of purpose was associated with higher self-rated health, smoking status, and cardiovascular disease cross-sectionally and self-rated health prospectively. Purpose was unassociated with changes in health over time. CONCLUSION: These results highlight the relationship of a key individual difference, sense of purpose, to the behaviors and outcomes of adults with diabetes. While more research is needed to determine the boundaries of this relationship, it seems sense of purpose may be considered in the future as a potential target for intervention.

From adversity to activism: A psychobiographical case study of Cori Bush.

INTRODUCTION: Cori Bush is a prominent modern activist in the U.S., becoming involved in activism following Michael Brown's death. Bush, like many activists before her, has set clear goals for social change, yet work is needed to understand why Bush (and like others) became an activist when others did not. One potential reason may be that these exemplars found purpose in life in activism. Thus, the current psychobiography explores the purpose in life of Cori Bush, a prominent activist and politician in the U.S., as well as what factors emerge for how Bush found her purpose in life. METHOD: The present research gathered public materials (e.g., speeches) from Bush and coded materials for the presence and depth of both themes of purpose and factors predicting purpose. RESULTS: Activism was the most prominent theme of purpose for Bush, with some pro-social purposes also occurring. Multiple personal factors emerged as influences on her activist purpose, including extraversion, psychological flexibility, and action-oriented coping style. Additionally, the situational factors of discriminatory experiences and Michael Brown's death emerged as factors. CONCLUSION: These results suggest that Bush has an activist purpose in life and that she found this purpose through a combination of personal and situational factors.

Self-control in adolescence predicts forgivingness in middle adulthood.

INTRODUCTION: This 33-year study examined associations between self-control development in adolescence and forgivingness, i.e., the dispositional tendency to forgive others, in middle adulthood. METHODS: Participants were 1350 adults aged 45 years (50.6% female). Self-control was measured yearly from age 12 to 16, while forgivingness was measured at age 45. RESULTS: Results indicated significant individual differences in level and change of self-control across the adolescent years and an average mean-level increase. Individual differences in level and change in self-control were independently associated with forgivingness in middle adulthood. Individuals who either entered adolescence with higher self-control, and/or increased in self-control during the adolescent years, reported higher scores in forgivingness at age 45 compared to peers. This pattern held even after controlling for gender, socioeconomic status (SES), and conduct problems in adolescence. CONCLUSION: The current findings demonstrate that developmental processes in adolescence are important for individual differences in the dispositional tendency to forgive others in adulthood.

Hope and healthy lifestyle behaviors in older adulthood.

OBJECTIVES: Hope has been associated with better health and social well-being outcomes, including emotional adjustment, positive affect, life satisfaction, reduced risk of all-cause mortality, and increased physical activity, yet how hope as a construct impacts these health benefits in older adults is not very well-understood. This study examined: (1) the relationship between hope and health behaviors in older adults; (2) how this relationship may differ across different socio-demographic groups; and (3) how hope relates to perceived future selves among older adults. METHODS: The study used cross-sectional data from 711 community-dwelling adults aged ≥55 years (280 men, 431 women). Survey measures included the Snyder Adult Dispositional Hope Scale (ADHS) and the Herth Hope Index (HHI), a health behaviors checklist, self-reported health, and a future self-scale. Data were analyzed using bivariate and multiple regressions. RESULTS: Hope was positively associated with healthy behaviors in older adults. Participants with higher levels of hope also reported more positive future selves and better health. The associations were similar across different racial/ethnic groups. CONCLUSIONS: This study fills an important gap in our understanding of hope and its association with health behaviors in community-dwelling older adults. These findings highlight a need to promote hope in older adults in order to enhance their sense of well-being.

Sense of purpose among transgender adults in the United States: comparisons of levels and health correlates.

Given the increased threats to health and well-being faced by transgender individuals, research is needed to understand potential protective factors. Recent work has suggested that a sense of purpose may be one of the health-promoting resources available to marginalized groups, and levels of purpose are often similar or even higher among these groups. However, research is limited regarding whether this factor manifests differently among transgender adults. The current study (n = 1968 U.S. adults; 4.3% identified as transgender) asked participants to complete surveys for sense of purpose, self-rated health, life satisfaction and the type of purposes they deemed important. The findings suggest no difference in levels of sense of purpose between transgender and non-transgender adults. Transgender adults reported slightly lower levels of importance across multiple purposes, which merits further investigation into whether they perceive greater obstacles toward those goals. Of central importance, sense of purpose positively correlated with self-rated health (r = .50) and life satisfaction for transgender adults (r = .77), at similar or even greater magnitudes than for the non-transgender adults. These results point to the potential of exploring sense of purpose as an intervention target for promoting transgender health and well-being, and future directions should focus on the multiple pathways by which transgender identity may influence purpose development.

Older Adults Place Greater Importance Than Younger Adults on a Purposeful Retirement.

Objective: Regarding retirement, some but not all people decline in sense of purpose, and retirees may view maintaining a sense of purpose as nonessential. These findings suggest individual differences both in the importance placed on being purposeful during retirement in general and the discrepancy for purpose importance prior to and during retirement. Method: This study surveyed U.S. adults (n = 2009, Mage = 48.51) asking them about how they viewed having a purpose in two life stages: before and during retirement, as well as personality and demographic questions. Results: Findings suggest that, overall, people believe it is important to have a purpose and direction during retirement. This tendency was greater among older adults, and those higher on conscientiousness or lower on neuroticism. However, working status did not play a role in the perceived importance of purpose during the retirement period. Moreover, age differentiated who perceives during-retirement purpose as more important than prior-to-retirement purpose. Conclusion: The current findings add to our understanding of when individuals expect to be purposeful and counter the claims that older adults may place less importance on being purposeful. Instead, these findings point to the need for continuing work on how to help older adults maintain or find a purpose in life following retirement.

Being Social May Be Purposeful in Older Adulthood: A Measurement Burst Design.

OBJECTIVE: Sense of purpose predicts a wide array of positive health, cognitive, and well-being outcomes during older adulthood. However, work is limited regarding how social relations correspond to purposefulness in daily life. The current study explored daily social interactions as a route to daily purposefulness in older adults, using a measurement burst design. METHODS: Older adults completed surveys for three 5-day bursts each spread 6 months apart (Mage = 70.75, SD = 7.23; N = 104). RESULTS: Multilevel models demonstrated that on days when individuals reported more positive social interactions, they reported feeling more purposeful (est. = 0.39, 95% CI [0.28, 0.51]) when accounting for health, employment, and relationship status. Employment status moderated this association, as daily social interactions were more strongly associated with daily purpose for unemployed/retired individuals (est. = -0.23, 95% CI [-0.38, -0.08]). CONCLUSION: Positive social interactions thus may help older adults maintain purposefulness, particularly after retirement.

Vitamin D deficiency and insufficiency in Hawaii: Levels and sources of serum vitamin D in older adults.

OBJECTIVE: To examine the major sources of vitamin D [25-hydroxyvitamin D (25(OH)D)] and evaluate their collective role on rates of vitamin D deficiency/insufficiency among older adults. METHODS: Cross-sectional analysis of the relationship between serum 25(OH)D levels and sources of vitamin D (self-reported and objectively validated sun exposure, supplementation, food including fortified sources). Study subjects were part of the Hawaii Longitudinal Study of Personality and Health who completed a clinic visit between 55 and 65 years (M = 59.6) and food frequency questionnaire, and provided serum to assay 25(OH)D (n = 223). RESULTS: Although mean serum 25(OH)D levels were overall sufficient (34.3 ng/ml, [SD = 10.9]), over one-third of participants (38%) had vitamin D deficiency/insufficiency (<30 ng/ml). Asians were the most likely to be insufficient and Filipinos were the least likely (43% vs. 11%, respectively). Overall, supplement use and sun exposure were both associated with higher 25(OH)D levels and lower risk of vitamin D deficiency/insufficiency. Moreover, Vitamin D sources varied by race/ethnic groups. In multivariate models, higher body mass index, being Asian or Native Hawaiian/Pacific Islander, low supplement use, and low sun exposure were associated with higher risk for vitamin D deficiency/insufficiency (<30 ng/ml). CONCLUSIONS: Over 1/3 of the older adult sample was vitamin D deficient/insufficient, despite most of the participants living in a tropical climate with year-round access to sun as a vitamin D source. Sun exposure and supplement use, but not food intake, explained differences in vitamin D deficiency/insufficiency in this population.

Sense of purpose as a potential buffer between mental health and subjective cognitive decline.

OBJECTIVES: Purposeful adults may experience greater cognitive resilience because sense of purpose may help buffer against the effects of depressive symptoms and loneliness. We also evaluated whether these associations differed by race. DESIGN: This study uses a wave of self-report data from the SPAN study of psychosocial aging. SETTING: Participants come from a representative sample of older adults in St. Louis. PARTICIPANTS: Participants (N = 595) ages range from 65 to 78 (Mage = 71.46), with 18.3% of participants identifying as Black/African-American. MEASURES: Sense of purpose was assessed with the Life Engagement Test, depressive symptoms with the Beck Depression Inventory-II, loneliness with the UCLA Loneliness Scale, and subjective cognitive decline with the AD-8. RESULTS: Correlational analyses supported predictions that sense of purpose was negatively related to subjective cognitive decline, whereas depressive symptoms and loneliness were positively related (|r|s > .30, ps < .001). For loneliness, but not depression, this association was moderated by sense of purpose (b = -0.43, p < .001). A relatively high sense of purpose attenuated associations between loneliness and subjective cognitive decline. A three-way race × purpose × loneliness interaction (b = -0.25, p = .021) revealed that the buffering effects of sense of purpose on subjective cognitive decline were stronger for Black adults. DISCUSSION: This study provided partial support for the buffering hypothesis, showing that sense of purpose may help mitigate the cognitive decrements associated with loneliness. Future research needs to consider how purpose-promoting programs may support healthy cognitive aging, particularly among Black older adults and those who experience greater social isolation.

Associations between depressive symptoms with perceived future time and opportunities: tests of unique prediction and moderation.

OBJECTIVES: Having a broadened perspective on one's future has been associated with better affective well-being, including reduced reports of depressive symptoms. However, research is limited regarding which aspect of future time perspective is associated with depressive symptoms, and whether these findings are consistent across individuals. METHODS: The current study employed data from a nationally representative sample of Swiss adults (n = 1774; mean age: 49.90 years; 51.8% female). Participants completed measures of future time perspective - both perceptions of future time and future opportunities - and depressive symptoms, in addition to reporting on their age, sex, health, and socioeconomic status (the moderators of interest). RESULTS: Perceived future time and future opportunities were uniquely predictive of depressive symptoms, even when controlling for chronological age and other covariates, though future opportunities held a stronger association with depressive symptoms. Limited evidence was found for moderation, though opportunities may matter more for predicting depressive symptoms among adults in worse health and those with fewer resources. DISCUSSION: Future time perspective appears moderately associated with depressive symptoms in adulthood, and researchers need to consider multiple aspects of future time perspective rather than as a unitary construct.

Purposeful retirement expectations and their associations with retirement planning.

OBJECTIVE: Previous research has demonstrated that retirees tend to report lower levels for sense of purpose compared to working adults. However, it remains unclear whether adults show differences in the extent to which they expect to be purposeful during retirement, and what that may mean for the propensity to plan for retirement. METHOD: The current study examined this question in a cross-sectional sample of 492 adults (Age: M = 39.28, SD = 8.35) prior to retirement. Participants completed an adapted measure to capture expected purposeful engagement during retirement, along with sense of purpose, retirement planning, and the Big Five personality traits. RESULTS: Factor analyses and zero-order correlations suggested that purposeful retirement perceptions are related yet distinct from sense of purpose in general, and adults on average expect a moderately purposeful retirement. Purposeful retirement scores were associated with multiple retirement planning scales, and remained predictive of retirement preparation even when accounting for the Big Five and demographic factors. CONCLUSION: Adults differ in how purposeful they expect to be during their future retirement. Moreover, these differences may be a valuable consideration when understanding how to promote retirement planning.

When the end feels near: sense of purpose predicts well-being as a function of future time perspective.

OBJECTIVES: While sense of purpose is a robust predictor of well-being, little work has considered whether the associations vary based on future time perspective. Exploring this possibility is important given that the extent to which one may pursue their life aims could be dependent upon how much time they feel that they have remaining. METHODS: Using three samples (total n = 2333), the current study considered the association between sense of purpose and future time perspective. Moderation tests also examined whether the associations between sense of purpose and three well-being components (positive affect, negative affect, life satisfaction) differed as a function of future time perspective. RESULTS: Across all three studies, people with a broader time perspective reported a higher sense of purpose. Both constructs predicted greater well-being, even after accounting for chronological age. Future time perspective moderated the associations between sense of purpose and well-being, such that the negative association between sense of purpose and negative affect was stronger for those with a broader time perspective and the positive association between sense of purpose and life satisfaction was stronger for those with a limited time perspective. CONCLUSION: The well-being benefits associated with sense of purpose in adulthood may depend on future time perspective. Findings are discussed in the context of how purpose can be harnessed to enhance well-being even when older adults feel that their time left is limited.

Sleep quantity and variability during the first semester at university: implications for well-being and academic performance.

Research has demonstrated the importance of sleep quality for university students, although work is limited with respect to how sleep during the first semester of school impacts well-being and academic outcomes. The current study sought to examine the role of sleep quantity and variability over the first semester of university on GPA and happiness. Students (n = 97) from a first-semester psychology course completed weekly assessments of sleep and well-being (happiness and anxiety) for 15 weeks, and they gave permission for researchers to collect their GPA and SAT data from the registrar. Average weekly sleep quantity was associated with greater weekly happiness and less anxiety. Weekly sleep variability was associated with lower happiness and more anxiety. Even when accounting for sleep quantity and initial start-of-semester measures, sleep variability predicted worse GPA and happiness for students at the end-of-semester. In summary, sleep consistency may be an important target for health professionals working within the university setting. This study contributes to the literature on the importance not only of sleep but also of sleep consistency, during a major life transition.

A prospective study of college student depressive symptoms, sense of purpose, and response to a COVID-19 campus shutdown.

Individual differences can shape the way major life events are experienced. In this study, we explored the unique and interactive effects of depressive symptoms and sense of purpose on downstream appraisals of a COVID-19 college campus shutdown. Data were from a sample of U.S. college students (n = 152) surveyed prior to widespread COVID-19 transmission (Time 1; early fall 2019), and again just after their university closed as a protective measure (Time 2; mid-spring 2020). Depressive symptoms were positively associated, whereas sense of purpose was negatively associated, with cross-sectional reports of social status change due to shutdown. Depressive symptoms at Time 1 positively predicted perceived external control of the situation at Time 2, and sense of purpose at Time 1 positively predicted changes to worldview at Time 2. Purpose and depressive symptoms evidenced high rank-order stability from Time 1 to Time 2. This study represents a rare documentation of college students' feelings and experiences before, and during, a historical moment. The implications of these findings for future research are discussed.

Considering Financial Assets When Promoting Sense of Purpose in Older Adulthood.

Sense of purpose, a consistent promoter of successful aging across the lifespan, has been shown in previous research to decline during older adulthood. As such, research is needed to understand how to inform policies around promoting a sense of purpose for older adults, and which adults may need more assistance on this front. One potential mechanism for lower purpose in older adulthood could be due to the more limited financial assets many face following retirement. As such, the current study investigated the cross-sectional associations between different kinds of financial assets and sense of purpose among older adults from the 2006 and 2008 waves of the Health and Retirement Study (n = 9,380). Sense of purpose as well as four financial assets were assessed: physical assets, retirement account assets, investment account assets, and debts. Findings indicated that greater physical assets and retirement account assets predicted a higher sense of purpose, while debt and investment account assets did not. Furthermore, there were no moderating effects of different grouping variables, such as retirement status, race, marital status, subjective health, or wave, on the associations between total net worth and sense of purpose. Findings are discussed regarding why net worth matters for all, and why certain assets may be more important than others when promoting a sense of purpose.
