Note: Adjusted for sex, age, education, marriage, employment, and income factors for each group. Each variable was categorized as follows: Male sex was used as categorical data. Age was used in the analysis as “non‐elderly” if the age was less than 65. Educational background was used in the analysis as “high educational background” if the respondent had a junior college or university degree or higher. Marital status was used in the analysis of “whether the respondent has been married or not” as a confounding factor. In the analysis, working status was defined as “not working” if the respondent was unemployed or retired. Respondents were asked to answer on a 4‐point scale their annual household income (1.5, 3, and 5 million yen), and whether the income was 3.01 million yen or more was used for the analysis. The above average JPCAT‐SF score used as an explanatory variable.
