Refereed, PLOS Mental Health, Public Library of Science (PLoS), Heart rate variability versus visual analog scale for objective and subjective mental fatigue detection: A randomized controlled trial, Hiroaki Yoshikawa; Yumi Adachi; Ayako Baba; Chiaki Takikawa; Yuya Yamaguchi; Wakana Nakai; Daiki Sudo, Fatigue is a multidimensional phenomenon. Although psychological tests can be used to evaluate subjective fatigue, an objective measurement of fatigue is needed to evaluate mental, physical, and occupational health and inform appropriate interventions. Heart rate variability (HRV) has emerged as a potential candidate for assessing objective mental fatigue; however, its effectiveness and safety remain inconclusive. To address these, we conducted a single-center, randomized trial to compare the efficacy and safety of HRV with subjective psychological tests for evaluating mental fatigue. Participants aged 20 to 65 years who had received annual health check-ups and had been found to have no health concerns were included in this study. We compared HRV indexes after performing a calculation task with a control group that rested. The primary outcomes were HRV indexes as recorded by wearable electrocardiography after an intervention consisting of a calculation task. Subjective measures (visual analog scale [VAS] for fatigue and Profile of Mood States 2nd Edition [POMS2]) were evaluated as secondary outcomes. One hundred forty participants were randomized into a calculation task and control groups. Participants who performed the calculation task had a lower square root of the mean squared differences between successive RR intervals (RMSSD), absolute power in the high-frequency band, and standard deviation of Poincaré plot. In psychological tests, participants who performed the calculation task demonstrated significantly higher scores on the VAS for fatigue and POMS2. Multiple comparisons of RMSSD from HRV indexes, VAS for fatigue, and total mood disturbance from POMS2 revealed that RMSSD and VAS for fatigue were significant indicators associated with the calculation task. On the other hand, the vectors of HRV indexes and psychological tests differed based on primary component analysis. We identified RMSSD, an objective index, and VAS for fatigue, a subjective index, as significantly related to mental fatigue., 24 Jan. 2025, 2, 1, e0000240, e0000240, Scientific journal, 10.1371/journal.pmen.0000240

Geriatrics & Gerontology International, Multifaceted well‐being experienced by community dwelling older adults engaged in volunteering activities of frailty prevention in Japan, Yaka Matsuda; Ayako Baba; Ikuko Sugawara; Bo-Kyung SON; Katsuya Iijima, AimThis study aims to elucidate what volunteering activities mean for older adults in Japan by analyzing their emotions and evaluations from hedonic (e.g., happiness), eudaimonic (e.g., self‐growth), and social (e.g., social coherence) well‐being.MethodsThe qualitative research was conducted to describe the subjective experience of older adults' volunteering activities (frailty checkups) in the community‐setting. Eight older adults were interviewed about their experiences during these activities. The interview data were analyzed from two assumption frameworks: first, three aspects of well‐being, and second, timeframes of well‐being, during the activity, medium‐term, and long‐term. Previous studies have not focused on the polysemy or the timeframe of well‐being.ResultsOur results showed that hedonic, eudaimonic, and social well‐being are not independent, but overlap. Furthermore, even if older adults experience certain emotions at a point of time, they may change in the long term. This implies that it is important to analyze older adults' feelings and experiences from not only one aspect but from different perspectives and measure their feelings not just at a particular moment but in the long term. This is the first empirical study to examine qualitatively the holistic experiences of well‐being among older adults who volunteer.ConclusionsWe conclude that this study is unique in that it attempted to associate empirically the experiences of older adults during volunteering with their general psychological status of well‐being. These findings could help make volunteering activities more meaningful for older adults and create or promote an active community.
