Lifestyle factors such as physical and cognitively stimulating activities may protect against various diseases. However, only a few simple and validated questionnaires assess the lifestyle factors in Japan. Thus, we aimed to create Japanese versions of such questionnaires for assessing physical and cognitively stimulating activities. This study examined their inter-rater reliability and test-retest reproducibility.
We developed a Japanese version of questionnaires by translating the English questionnaire that assesses the frequency of several physical and cognitively stimulating activities. Additionally, the Japanese version assesses the duration of engagement in physical activities, and we have added mental activities such as meditation and Zen practice. The inter-rater reliability and test-retest reproducibility of evaluating the frequency, duration, frequency × duration of each physical activity, and frequency of each cognitively stimulating activity were tested in healthy volunteers.
The study included 48 participants aged 25-67 years. We observed good inter-rater reliability and test-retest reproducibility for the physical and cognitively stimulating activity questionnaires. As a pilot approach, we calculated the Total Physical Activity Score (metabolic equivalents·min/week) with an intraclass correlation coefficient (ICC) (2,1) of 0.818 (95% confidence interval, 0.698-0.894), indicating good test-retest reproducibility.
The Japanese versions of questionnaires used to assess the frequency and duration of physical and cognitively stimulating activities generally have good inter-rater reliability and test-retest reproducibility. While introducing the duration of engagement might enable the estimation of the Total Physical Activity Score, further validation using objective measures of activities and other self-reported physical activity questionnaires is necessary, which is a limitation of this study.
诸如体育活动和认知刺激活动等生活方式因素可能预防多种疾病。然而，在日本，仅有少数简单且经过验证的问卷可评估生活方式因素。因此，我们旨在创建此类问卷的日语版本，以评估体育活动和认知刺激活动。本研究检验了它们的评分者间信度和重测信度。
我们通过翻译一份评估多项体育活动和认知刺激活动频率的英文问卷，开发了一个日语版问卷。此外，日语版问卷还评估了体育活动的参与时长，并且我们增加了冥想和禅修等心理活动。在健康志愿者中测试了评估每项体育活动的频率、时长、频率×时长以及每项认知刺激活动频率的评分者间信度和重测信度。
该研究纳入了48名年龄在25至67岁之间的参与者。我们观察到体育活动和认知刺激活动问卷具有良好的评分者间信度和重测信度。作为一种初步方法，我们计算了总体育活动得分（代谢当量·分钟/周），组内相关系数（ICC）（2,1）为0.818（95%置信区间，0.698 - 0.894），表明重测信度良好。
用于评估体育活动和认知刺激活动频率及时长的日语版问卷总体上具有良好的评分者间信度和重测信度。虽然引入参与时长可能有助于估算总体育活动得分，但有必要使用活动的客观测量方法和其他自我报告的体育活动问卷进行进一步验证，这是本研究的一个局限性。
