      • Physical and cognitive functioning to explain the quality of life among older adults with mild cognitive impairment

        Xing Fan,Jisu Seo,YueLin Li,Ahyun Ryu,Kyoungok Joo,Moonkyoung Park,Rhayun Song 한국간호과학회 2021 한국간호과학회 학술대회 Vol.2021 No.10

        Aim(s): Physical and cognitive functioning are both indicators of aging process. Older adults experience abnormal declines in physical and cognitive functioning that increase their risk of dependence, subsequently quality of life. This study aims to explore the relationship between physical and cognitive functioning, and mediation effect of cognitive functioning on the relationship of physical functioning and health-related quality of life among older adults with mild cognitive impairment. Method(s): Seventy-nine older adults living in community participated in the study. Measurements included the self-reported questionnaire for physical functioning consisted of grip strength, one leg standing with eyes open (balance), and Timed Up and Go (mobility). Cognitive functioning was measured by Korean version of MOCA. SF-12 was used to assess physical and psychological components of quality of life (QOL). Data were using multiple regression and a simple mediation model applying the PROCESS macro for mediation. Result(s): Physical functioning explained 14.5% of variance in cognitive functioning. Physical and cognitive functioning together explained 22.4% of variance in physical component of QOL, 18.7% of variance in mental component of QOL. Indicators of physical functioning significantly related with cognitive functioning with balance (B=0.41, p=.02). Cognitive functioning had significant indirect effects B= 0.19, 95%CI (.491~.008) between balance and physical component of QOL, while the indirect effects was not significant with mental component of QOL (B=0.06, 95%CI -.107~0.332). Conclusion(s): The findings showed cognitive functioning had a significant mediating effects between the physical functioning and physical components of QOL. These findings have suggested that nursing intervention to improve physical functioning such as balance, mobility and grip strength may also improve cognitive functioning, consequently improving physical component of QOL for older adults with mild cognitive impairment. Further studies are warranted to explore the effects of health promotion programs designed to enhance physical and cognitive functioning in this population.

      • Assessing physical activity for frail elderly living in the community

        YueLin Li,Ahyun Ryu,Xing Fan,Jisu Seo,Kyoungok Joo,Moonkyoung Park,Rhayun Song 한국성인간호학회 2021 성인간호학회 학술대회 Vol.2021 No.8

        Background: Physical activity (PA) measurement for the frail elderly is essential, yet existing assessment tools are difficult t apply for this population. Objective methods of monitoring PA would be accurate, but costly and limited to a small number of participants. Subjective methods of measuring PA among the elderly often lead to less reliable information, especially among frail elderly. The newly developed Assessment of Physical activity in Frail Older People (APAFOP) focuses on items that have different intensity ratings and better represent typical forms of activity in frail elderly, and closely guarded the occurrence of system error through prevents floor and ceiling effects, which other measurements failed in this regard. Aim(s): The purposes of this study were to translate and validate the APAFOP scale into Korean and Chinese and to find the adaptability of the tool through preliminary research in a sample of frail elderly living in the community. Method(s): The APAFOP was translated into Korean and Chinese versions based on the established guideline for cross-cultural adaptation of self-report measures from Beaton et al. Kendall’s coefficient of concordance W was used to assess the consistency of activity scores between the translated version and the original English version. Result(s): The initial version of APAFOP applied to the sample of frail elderly with translated versions showed a consistency W=0.912 (c2= 9.118, R=0.104) for the Chinese version and W=0.362 (c2=3.261, R=0.660) for the Korean version. The following adjustments were suggested for translated version to improve the consistency: (1) the definition of related activities is required to be more specific, (2) the time line of previous 24 hours should be strictly regulated, (3) a user manual was required to the translated versions to help researchers understand and apply the scale with the standardized protocol. Conclusion(s): This preliminary study was conducted for the first validation and adaptation of the APAFOP in the Korean and Chinese settings and found that the translated version revealed the potential applicability as the modified objective measure of PA among frail elderly living in the community. The further process of cultural adaptation of the APAFOP would be warranted to compare the scale with current objective measures (e.g., pedometer) to establish criterion valigity.
