Checklist for Habitual Physical Activity (CHaPA) for adults 75 years and older: tool development and content and face validation.

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.

Social support as a bridge: A rapid realist review of migrant inclusion in the Japanese response to the COVID-19 pandemic.

Government policy to address the COVID-19 pandemic has been complex with profound impacts on vulnerable minorities like international migrants. In Japan migrants are an important and growing community but their consideration in health policy is rare. We conducted a rapid realist review about 'what works' for the equitable inclusion of migrants during the pandemic as a case study for other public health emergencies. Due to the time-sensitive needs of policy-makers in the ongoing COVID-19 emergency, our evidence search was purposive, yet exploratory and iterative in nature. We assessed academic and gray literature sources, published in either English or Japanese, that examined the policy response to COVID-19 in Japan and its impact on migrants. A panel of external stakeholders was also consulted during the review process. This evidence synthesis suggests that, rather than illness alone, restrictions on movement and socioeconomic background lead to the considerable impact of policy on the well-being of migrants. Many policy responses, while conceptually inclusive and flexible, were often structurally inequitable for migrants. Poor outcomes included confusion about changing virus-related regulations and need for technical assistance to access support. Social support from volunteers and non-profit organizations were consistently left to connect migrants with unmet needs to available services. Using the diverse international community of Japan as an example, we show that, during public health emergencies, social support from civil society remains crucial for bridging structural inequities. For equitable inclusion of migrants, evidence-informed policy will be key for governments to better protect migrants' right to health and well-being in future emergencies.

Competence in Daily Activities and Mental Well-Being among Technical Intern Trainees in Japan: A Cross-Sectional Study.

Migrant workers are at a greater risk of having low mental well-being compared to their local counterparts. The Japanese government accepts migrants through its Technical Intern Training programs, but the factors associated with their mental well-being remain unclear. This study aimed to (1) assess trainees' competence and importance in daily activities and (2) examine the association between their competence and mental well-being. We conducted a cross-sectional study using self-administered questionnaires. We recruited trainees through their supervising organizations and social media. We used the Occupational Self-Assessment tool to measure competence and importance in daily activities and the World Health Organization-5 Well-being Index to measure mental well-being. Hierarchical regression analysis was used to examine the association between competence and mental well-being. Among 383 trainees, 30.6% felt difficulty expressing themselves, and 27.4% felt difficulty accomplishing goals. Almost 50% valued self-care, working towards their goals, and managing their finances. Higher competence scores were associated with higher mental well-being scores (B = 0.76; 95% CI = 0.52, 1.00). Competence may be a key to having higher mental well-being among migrant trainees in Japan. A supportive and enabling environment, as well as mental health promotion at the community level, may improve trainees' competence in daily activities.
