Data Sheet 1_Japanese version of the motivation to change lifestyle and health behaviors f

A 2026 validation study of a psychometric scale assessing motivation to change lifestyle for dementia risk reduction among Japanese adults. The dataset likely contains survey responses from 500 Japanese adults aged 40–89 years, collected online by author Fumiya Nakai. The study evaluated the scale's reliability and validity, including factor analysis and test-retest reliability over 2 weeks.

Use Cases

• Validate psychometric instruments based on the Health Belief Model using factor analysis results.
• Study motivation for lifestyle change in dementia prevention among an older Japanese population.
• Analyze the cross-cultural adaptation of health behavior scales using translation and validation methods.
• Investigate correlations between subscale scores and demographic factors like age.

Strengths

• Dataset is based on a sample of 500 Japanese adults.
• Scale validation includes internal consistency (Cronbach's α > 0.7 for all seven subscales) and test-retest reliability.
• Exploratory factor analysis explained 58% of the variance, supporting construct validity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and age bias inherent to the online sample of Japanese adults aged 40-89.
