Acceptance of aging among Japanese adults aged 20–89
Published 2025-12-01“…Participants completed a questionnaire assessing the following variables: AARC, emotional evaluation of AARC, and aging acceptance.Results Logistic regression indicated that a positive evaluation of AARC was associated with greater acceptance of physical and psychosocial aging. Generalized linear modeling and chi-square tests showed that ‘Muscular/joint changes and appearance’ were types of AARC negatively evaluated and challenging to accept, whereas ‘Illness/injury’ was also negatively evaluated but easier to accept. …”
