Does Reflection on Everyday Events Enhance Meaning in Life and Well-Being among Emerging Adults? Self-Efficacy as Mediator between Meaning in Life and Well-Being

NASA resilience and leadership: examining the phenomenon of awe

This study examines how a phenomenon, awe, along with related resilience practices, is perceived by a NASA medical and mental health professional, who also serves in a leadership role, and how awe has impacted their work and personal life. Considering both their leadership role and how their work involves supporting the wellbeing of astronauts pre-mission, during missions, and post-mission, the potential impact of awe on the NASA expert has individual implications along with many others, especially in stressful environments. The results indicate that reflecting on awe experiences can support a person finding meaning and purpose in their life, evoke gratitude, increase social connectedness, promote optimism and other resilience skills in the moment, and generally have a sustainable positive effect.

Association of Self-reflection With Cognition and Brain Health in Cognitively Unimpaired Older Adults

BACKGROUND AND OBJECTIVES

Self-reflection (the active evaluation of ones thoughts, feelings, and behaviors) can confer protection against adverse health outcomes. Its effect on markers sensitive to Alzheimer disease (AD), however, is unknown. The primary objective of this cross-sectional study was to examine the association between self-reflection and AD-sensitive markers.

METHODS

This study used baseline data from cognitively unimpaired older adults enrolled in the Age-Well clinical trial and older adults with subjective cognitive decline from the SCD-Well clinical trial. In both cohorts, self-reflection was measured via the reflective pondering subscale of the Rumination Response Scale, global cognition assessed via the Preclinical Alzheimer's Cognitive Composite 5, and a modified late-life Lifestyle-for-Brain-Health (LIBRA) index computed to assess health and lifestyle factors. In Age-Well, glucose metabolism and amyloid deposition were quantified in AD-sensitive gray matter regions via fluorodeoxyglucose- and AV45-PET scans, respectively. Associations between self-reflection and AD-sensitive markers (global cognition, glucose metabolism, and amyloid deposition) were assessed via unadjusted and adjusted regressions. Furthermore, we explored whether associations were independent of health and lifestyle factors. To control for multiple comparisons in Age-Well, false discovery rate-corrected p values (p _FDR) are reported.

RESULTS

A total of 134 (mean age 69.3 ± 3.8 years, 61.9% women) Age-Well and 125 (mean age 72.6 ± 6.9 years, 65.6% women) SCD-Well participants were included. Across unadjusted and adjusted analyses, self-reflection was associated with better global cognition in both cohorts (Age-Well: adjusted-β = 0.22, 95% CI 0.05-0.40, p _FDR = 0.041; SCD-Well: adjusted-β = 0.18, 95% CI 0.03-0.33, p = 0.023) and with higher glucose metabolism in Age-Well after adjustment for all covariates (adjusted-β = 0.29, 95% CI 0.03-0.55, p _FDR = 0.041). Associations remained following additional adjustment for LIBRA but did not survive false discovery rate (FDR) correction. Self-reflection was not associated with amyloid deposition (adjusted-β = 0.13, 95% CI -0.07 to 0.34, p _FDR = 0.189).

DISCUSSION

Self-reflection was associated with better global cognition in 2 independent cohorts and with higher glucose metabolism after adjustment for covariates. There was weak evidence that relationships were independent from health and lifestyle behaviors. Longitudinal and experimental studies are warranted to elucidate whether self-reflection helps preserve cognition and glucose metabolism or whether reduced capacity to self-reflect is a harbinger of cognitive decline and glucose hypometabolism.

Chinese Youths' Physical Activity and Flourishing During COVID-19: The Mediating Role of Meaning in Life and Self-Efficacy

Physical activity has wide-ranging consequences for people's physical, mental, and social health. Although the beneficial effects of physical activity on well-being were widely studied, how it promotes well-being remained unclear. The present study utilized the measure of physical activity rating scale (PARS-3), flourishing scale (FS), Chinese- meaning in life questionnaire (C-MLQ), and general self-efficacy scale (GSES) to examine the connection between physical activity and flourishing and the multiple mediation effects of meaning and self-efficacy with 827 Chinese undergraduates. The results indicated that (a) physical activity positively predicted flourishing; (b) meaning in life and self-efficacy played mediating roles in physical activity and flourishing, separately and jointly. Our findings revealed the mechanism of physical activity fostering flourishing, thereby providing an empirical basis for promoting health and flourishing, especially during COVID-19.
