Empowerment among older adults is a key concept for improving their health. In contrast, empowerment evolves according to cultural and historical contexts and needs to be consistently tested and constructed. The purpose of this study was to clarify the components of older adults’ empowerment in contemporary Japan and to reconstruct the definition of empowerment. A conceptual analysis was performed using Rodgers’ evolutionary method. The data sources were PubMed, Cumulative Index to Nursing and Allied Health Literature, Web of Science, Cochrane Library, and Igaku Chuo Zasshi. The search keywords were “empowerment,” “older adults,” and “Japan/Japanese.” Of the 8811 articles published between 2000 and 2019 that focused on older adults’ empowerment, we selected 60 articles that met our objectives. Seven antecedents, six attributes, and seven consequences were identified. Older adults’ empowerment in contemporary Japan was defined as “the series of processes in which disclosing oneself, not only verbally but also nonverbally (e.g., through work, roles, and collaborative activities), in connection with others, objectively perceiving one’s existence and challenges, taking proactive actions based on decision-making, and utilizing one’s strengths in new work and community life.” This concept is useful in practice, education, and research on community development and providing support for older adults based on self-help and mutual aid, not only in Japan but also for the global aging society.

This cross-sectional study aimed to determine the association between phase angle (PhA) and physical activity intensity in community-dwelling older Japanese adults. The intensity and time of physical activity for predicting high PhA were also examined. This study involved 67 community-dwelling older adults (mean age: 78.3 ± 5.5; female: 83.6%). We measured the physical activity and body composition of the participants. Physical activity was measured using a triaxial accelerometer, and light-intensity physical activity (LPA) and moderate-to-vigorous intensity physical activity (MVPA) hours per day were calculated from the results. Body composition was measured using Inbody S10, and the PhA was calculated from the measurements of the right side of the body. Bayesian statistical modeling revealed an association between PhA and MVPA (β = 0.256; p = 0.022; 95% Bayesian confidence interval [CI] = 0.001, 0.012), but not LPA (β = −0.113; p = 0.341; 95% Bayesian CI = −0.002, 0.001), even after adjustment for confounders. The cutoff value of MVPA predicting high PhA, calculated by the receiver operator characteristic curve, was 19.7 min/d (sensitivity = 0.906; specificity = 0.429). These results can be used to develop strategies to increase PhA in older adults and suggest that MVPA is important in this population.

Empowerment scales for inpatients have been developed worldwide, but their validity and reliability have not been adequately tested and applied to the health promotion and care among older adults during hospitalization. In this study, the Patient Empowerment Scale developed by Faulkner was translated into Japanese, and Japanese patients were surveyed to test its clinical applicability. To test its applicability, 151 patients in rehabilitation wards were surveyed in four municipalities. After considering ceiling/floor effects and validating the structure, the Patient Empowerment Scale—Japanese comprised 37 items and six factors: subject–staff interaction, environmental adjustment through collaboration, necessary information gathering and problem awareness, proactive behavioral practices, self-disclosure, and self-management of activities. Criteria-related validity assessment confirmed the scale’s correlation with the Health Locus of Control Scale, General Self-Efficacy Scale, 13-item Sense of Coherence Scale, Rosenberg Self-Esteem Scale, and Philadelphia Geriatric Center Morale Scale. Regarding internal consistency, the Cronbach’s alpha was 0.93 for all 37 items. The Cronbach’s alphas for the six factors were 0.93, 0.91, 0.92, 0.92, 0.91, and 0.75, respectively. In our test/re-test of reliability, Spearman’s rank correlation coefficient between the first and second total scores was ρ = 0.96, p < 0.01. These results confirm the scale’s validity and reliability, and its applicability to older hospitalized patients.

In the present study, 151 Japanese older adults aged over 65 years and admitted to recovery-phase rehabilitation facilities were enrolled to investigate the relationship between empowerment and contextual factors, functioning and disability, with structural equation modeling (SEM). The analysis included 151 patients aged 81.75 ± 7.15 years, including 54 males (35.76%) and 97 females (64.24%). The results of the SEM analysis showed that role presence (β = 0.45, p < 0.01) and family structure (β = 0.18, p = 0.02) significantly impacted empowerment. In addition, the results showed that patient empowerment positively impacted physical activity (β = 0.25, p < 0.01) and psychosomatic functions and abilities (β = 0.36, p < 0.01). Furthermore, the goodness-of-fit of the model hypothesized in this study was shown to have explanatory power. This study showed that empowerment contributed to the prevention of physical inactivity and confinement among Japanese older patients. In other words, the study provided evidence for the importance of empowerment-based program planning in the practice of person-centered care aimed at promoting the health and discharge of older patients in Japan.
