Mothers with infants and toddlers are a potential target population for the prevention or alleviation of feelings of loneliness. However, the theory and methods for measuring loneliness among mothers with infants and toddlers have yet to be standardized worldwide, including in Japan. Our goal was to evaluate the reliability and validity of the Japanese version of the UCLA Loneliness Scale Version 3 (UCLA-LS3-J), as well as two short-form versions—the 10-item UCLA-LS3 (SF-10) and the 3-item UCLA-LS3 (SF-3)—for the measurement of loneliness in mothers with infants and toddlers in Japan. This cross-sectional study was conducted using a self-report questionnaire. The target population was 430 mothers with infants and toddlers who visited a community health center in Yokohama City in Japan. Questionnaire items encompassed the UCLA-LS3-J, as well as demographic data, the feeling for childrearing scale, and measures of social networks and subjective health status. The reliability and validity of the UCLA-LS3-J and its two short-form versions (SF-3 and SF-10) were determined via IBM SPSS Amos and SPSS Statistics 22. Questionnaires were returned by 248 mothers (valid response rate: 57.7%) aged 32.7 ± 4.6 (mean ± SD) years. The mean score on the UCLA-LS3-J was 38.4 ± 9.7 (range 20.0–73.0), with a normal distribution. When confirmatory factor analysis was carried out (for a single factor model), the goodness of fit of the model was almost identical to that of the original UCLA-LS3 version for the UCLA-LS3-J: (GFI = 0.882, AGFI = 0.840, CFI = 0.932, RMSEA = 0.066) and SF-10: (GFI = 0.942, AGFI = 0.900, CFI = 0.956, RMSEA = 0.081). The SF-3 model also showed an acceptable fit. The UCLA-LS3-J total score was significantly correlated with the total score on the SF-10 (r = 0.965) and SF-3 (r = 0.868). The Cronbach’s α coefficient of the UCLA-LS3-J was 0.926, while those of the SF-10 and SF-3 were 0.888 and 0.790, respectively. The score on the UCLA-LS3-J was positively correlated with childcare burden (r = .319, p < 0.001) and negatively correlated with social networks (r = −.438, p < 0.001). This study indicated that the reliability and validity of the UCLA-LS3-J as well as its two short-form versions were adequate for assessing loneliness in mothers with infants and toddlers in Japan.

We compared the shear forces exerted over the heel between a pressure ulcer preventive dressing and a thin-film dressing in a clinical setting. Interface pressures were measured as well. Quasi-experimental clinical trial. Participants were 30 elderly patients (5 men, 25 women; mean age, 86.4 ± 8.0 years) hospitalized in a geriatrics hospital in Japan; all had a Braden score of less than 14 (mean, 10.1 ± 1.1). Informed consent was obtained from all the patients. A shear force and pressure sensor including a strain gauge, and an oval airbag-type pressure sensor were used. The sensor was attached to one heel using double-sided tape; then the target dressing was applied over the sensor and on the opposite heel to avoid the influence of the opposite heel on the shear force measurement. Interface pressures were measured with the patient in a stationary supine position; shear force was then measured at 0.2-second intervals, while the sheet was manually pulled at a velocity of around 5 cm/second. Shear force was determined by averaging the stable shear force lasting for 10 measurement points. The mean interface pressures with the PPD and the film dressings were 70.7 ± 16.5 and 70.2 ± 15.2 mmHg, respectively; this difference was not statistically significant. The shear force produced during the pulling of the sheet was 2.2 ± 1.4 and 11.7 ± 5.8 N, respectively (P < .001, Wilcoxon signed-rank test). The results of this study suggest that a dressing with a low-friction external surface (such as the pressure ulcer preventive dressing) can significantly reduce shear force. However, results also suggest that external dressings do not significantly reduce interface pressures and cannot be used as a substitute for heel elevation in an immobile patient.

Elderly social isolation could be prevented by facilitating communication or mutual helping at the neighborhood level. The helping of elderly neighbors by local volunteers may relate to their community commitment (CC), but ways to measure CC have not been identified. The aim of the present study was to develop a Community Commitment Scale (CCS) to measure psychological sense of belonging and socializing in the community among local volunteers, for research in prevention of elderly social isolation. We also tested the CCS in a general population of the elderly.

Background: Globally, the population of oldest-old (those aged ≥80 years) is rapidly growing. This change is likely to have a deep impact on societies. Resilience is a key concept related to facilitating adaptation, and can be applied, to aging-related change and losses, as well as promoting health and well-being in this population. However, no existing scales have been developed to measure resilience among oldest-old people. To address this, we developed a resilience scale for oldest-old age (RSO), and examined its reliability and validity. Methods: The RSO is a self-administered questionnaire developed via a literature review, interviews with oldest-old individuals, and interviews with experts. The survey included 3000 community-dwelling oldest-old people who were recruited via random sampling in Yokohama city, Japan. Construct validity was determined using confirmatory factor analysis. Internal consistency was calculated using Cronbach’s alpha. The revised Philadelphia Geriatric Center Morale Scale (PGC) and the self-anchoring scale to measure the feeling that life is worth living (SAS-WL) were used to assess the criterion-related validity of the RSO. Results: We received 1283 valid participant responses. Confirmatory factor analysis identified nine items from one factor of the RSO with a goodness of fit index of 0.979, adjusted goodness of fit index of 0.963, comparative fit index of 0.973, and root mean square error of approximation of 0.049. Cronbach’s alpha was 0.800. The total RSO score was positively correlated with the PGC (r = .492, p < 0.001) and the SAS-WL (r = .559, p < 0.001). Conclusions: The RSO demonstrated adequate reliability and validity for assessing individual resilience among oldest-old people. Thus, the scale is potentially useful for promoting health and well-being in oldest-old age.
