ABSTRACT
BACKGROUND: Physical activity significantly contributes to older adults' physical and mental health, suggesting that physical activity could enhance healthy life expectancy. Despite its importance for adults aged 75 and older, activity levels among a large proportion of individuals aged 75 and older in Japan do not meet the recommended levels of physical activity, indicating a need for specific strategies tailored to this age group. This study aimed to develop a screening tool that measures daily activities promoting physical activity among older adults and assessed its content and face validity. METHODS: In Stage 1, we derived constructs pertinent to physical activity from previous literature and formulated an item list based on a prior qualitative study we undertook in Japan that evaluated daily behaviours facilitating physical activity among older adults. During Stage 2, we assessed the content and face validity of the list utilising the Nominal Group Technique (NGT), involving eight experts. The content validity was confirmed through two scoring evaluation rounds, while the face validity was verified through the NGT discussion, focusing on the comprehensibility and appropriateness of the tool. RESULTS: We created a tool with 22 items consisting of three constructs. The NGT participants modified eight of these items for the final assessment, resulting in a finalised tool comprising 22 items that satisfied the adaptation criteria. The content validity of these items was affirmed by median adequacy (>5.0 points) and interquartile range (<1.0 points). The NGT discussion consensus also confirmed satisfactory face validity. CONCLUSION: The newly developed tool, Checklist for Habitual Physical Activity (CHaPA) for adults 75 years and older, is a valid screening tool to assess the daily behaviours that facilitate physical activity. This self-administered instrument aims to assist older adults who need to start and maintain physical activity daily. Before its widespread public deployment, further investigation of the tool's validity and reliability is necessary.

Background: This study attempts to determine whether a program focused on improving literacy in daily living is effective in preventing physical frailty, and to compare standard treatments for physical frailty. Methods: This study was designed as a pilot intervention study involving two groups. Twenty-five older adults aged 65 to 85 in Ward A, Tokyo, were randomly assigned to the literacy group or the exercise group on a regional basis and were given a 60- to 90-minute program twice a month, eight times over four months. The literacy group mainly used video materials to monitor learning, and the exercise group used a multifactor exercise program. Results: The LSI-Z, GAS-L, Maximum 5 m walking time, and TUG tests showed the main effects before and after the intervention in both groups (p < 0.05, p < 0.01). The WHOQOL26, Maximum 5 m walking time, and TUG tests also showed the main effects across both groups (p < 0.05). Conclusion: Both programs, when implemented independently, showed specific effects on subjective well-being, occupational performance, and physical fitness. However, QOL and physical fitness were significantly higher in the exercise group than in the literacy group. These results should be considered with caution because of the limited sample size of this pilot study.
