Abstract

This study aimed to verify the mediating effect of depression and the moderating effect of the Zhongyong attitude on the relationship between social isolation and suicidal behavior of young adults by dividing them into occupational and non-occupational groups. A questionnaire survey including the online self-report was conducted using the scale of social isolation among young adults, the center for epidemiological studies-depression scale (CES-D), suicidal behaviors questionnaire-revised (SBQ-R), and the Zhongyong questionnaire (ZQ) targeting 350 young adults. The results are as follows. First, the social isolation of young adults showed a positive correlation with depression and suicidal behavior, and a negative correlation with the Zhongyong attitude. Second, in both groups, depression completely mediated social isolation and suicidal behavior of young adults. Third, there was no moderating effect in the relationship among social isolation, depression, and suicidal behavior in the entire group, but the moderated mediating effect of the Zhongyong attitude was significant in the isolated young adults with a job.
