Culturally and linguistically different immigrants in the U.S. are considered populations with low health literacy in general, thereby having a high risk of negative health outcomes such as frailty. The purpose of this study is to identify the effects of social support and acculturation on the relationship between health literacy and frailty of Korean immigrants in existing models of health literacy. A total of 244 Korean immigrants aged 50 years and older residing in Southern United States (Alabama and Georgia) were recruited. Path analysis was used to examine the pathways among variables, and the indirect effects of health literacy were analyzed. The results revealed that health literacy and social support directly influenced frailty; social support and acculturation were identified to influence health literacy. Health literacy had a partial mediating effect in the relationship between social support and frailty and a complete mediating effect in the relationship between acculturation and frailty. Therefore, to prevent frailty, it is necessary to consider enhancing immigrants’ health literacy by elevating acculturation and social supports.

Purpose: To test the reliability and validity of the Korean version of the Person-centered Climate Questionnairestaff version (KPCQ-S) in long-term care institutions. Methods: A total of 297 staff in long-term care institutions including nine nursing homes (NHs) and 4 long-term care hospitals (LTCHs) were included. The KPCQ-S was developed following the WHO guidelines of the process of translation and adaptation of instruments. An internal consistency using Cronbach's ⍺ was tested for reliability. Exploratory factor analysis (EFA) was used to examine the construct validity. Convergent and discriminant validity were examined using Pearson correlation. Results: EFA demonstrated the construct validity of the 14-item KPCQ-S with three-factor solutions, specifically three factors (safety, everydayness, and community) in NHs and four factors (safety, everydayness, community, and comprehensibility) in LTCHs. Convergent validity was found in the correlation with the work satisfaction (r=.55). The KPCQ-S showed satisfactory internal consistency reliability (Cronbach's ⍺=.91). Conclusion: The KPCQ-S is found to be a reliable and valid tool for measuring staff perceptions of the person centeredness of long-term care environments.

As the number of smartphone use by older adults increases, investigating the effects of smartphone use on health outcome become important in healthcare. This study aimed to investigate the effects of smartphone use on life satisfaction and the mediating role of depressive symptoms in older adults. This is a secondary data analysis study using the 2017 Korean Media Panel Survey. A total of 2071 respondents aged 65 years and older were analyzed to examine the effects of mobile phone type (no mobile phone/2G phone/smartphone) on life satisfaction. Among the respondents, data from 680 smartphone owners were analyzed to find the effects of the level of smartphone use on life satisfaction. The 2G mobile phone and smartphone owner groups showed significant positive effects on life satisfaction compared with the no mobile phone group, respectively. The level of smartphone use showed significant positive effects on life satisfaction. Depressive symptoms played a mediating role in both models. Smartphone use showed positive effects on life satisfaction in older adults. Nurses should promote the well-being of older adults and minimize the digital health gap in the future by increasing older adults' smartphone use through multi-level approaches.
