Behavioral and Functional Adaptation to Chronic Stress in Older Adults

Background The wear and tear from chronic stress exposure has been linked to premature aging through allostatic load; however, it is unclear how chronic stress exposure affects physical functioning and physical activity in older adults. Objectives The study aims were to examine the behavioral and functional adaptation to chronic stress in older adults and its mediational pathways. Methods Data from the Health and Retirement Study 2016 and 2020 (N = 3075, mean age 66 years) were analyzed. Chronic and perceived stress exposure was quantified using Troxel’s Chronic Stressors Scale and Cohen’s Perceived Stress Scale. Physical activity was quantified using self-reported questionnaires, including light, moderate, and vigorous physical activity. Physical functioning was operated as a latent construct with four perceived physical limitations (i.e., difficulty in movement, hand strength, shortness of breath, and balance). The cross-sectional data were analyzed using latent regression analysis. The longitudinal data were analyzed using serial mediation based on MacKinnon’s bias-corrected bootstrap confidence intervals. Results Cross-sectionally, psychological stress, as a latent construct indicated by stress exposure and stress perception, explained more variances in perceived physical limitation than physical activity. Longitudinally, perceived stress and physical activity mediated the relationship between chronic stress exposure and perceived physical limitation with significant indirect effects. Furthermore, perceived physical limitation suppressed the effect of chronic stress exposure on physical activity levels. The effects of mediation and suppression remained significant after the adjustment for age, gender, years of education, race, number of comorbidities, working status, and marital status. Discussion The promotion of physical activity and physical functioning in older adults might not achieve the optimal outcome if the program design overlooks the target population’s chronic stress process and functional limitations.

Reliability and Validity of Measures Commonly Utilized to Assess Nurse Well-Being

Background A healthy nursing workforce is vital to ensuring that patients are provided quality care. Assessing nurses' well-being and related factors requires routine evaluations from health system leaders that leverage brief psychometrically sound measures. To date, measures used to assess nurses' well-being have primarily been psychometrically tested among other clinicians or nurses working in specific clinical practice settings rather than in large, representative, heterogeneous samples of nurses. Objectives This study aimed to psychometrically test measures frequently used to evaluate factors linked to nurse well-being in a heterogeneous sample of nurses within a large academic health system. Methods This cross-sectional, survey-based study used a convenience sample of nurses working across acute care practice settings. A total of 177 nurses completed measures, which included the Professional Quality of Life, the short form of the Professional Quality of Life measure, the two-item Connor–Davidson Resilience Scale, the five-item World Health Organization Well-Being Index, the Secondary Traumatic Stress Scale, and the single-item Mini-Z. Internal reliability and convergent validity were assessed for each measure. Results All the measures were found to be reliable. Brief measures used to assess domains of well-being demonstrated validity with longer measures, as evident by significant correlation coefficients. Discussion This study provides support for the reliability and validity of measures commonly used to assess well-being in a diverse sample of nurses working across acute care settings. Data from routine assessments of the nursing workforce hold the potential to guide the implementation and evaluation of interventions capable of promoting workplace well-being. Assessments should include psychometrically sound, low-burden measures, such as those evaluated in this study.
