title: Association between interpersonal trust, reciprocity, and suicidal behaviors: A longitudinal cohort study in South Korea.
abstract: While a growing body of evidence suggest that social capital including interpersonal trust and reciprocity might be associated with mental health outcomes, few studies have explored the relationship with suicidal behaviors. This research examined the prospective association between interpersonal trust and reciprocity and suicidal behaviors using the Korea Welfare Panel Study, a nationally representative longitudinal cohort dataset in South Korea. Interpersonal trust and reciprocity were assessed at the 7th wave of the survey (2012), and each measure was classified into two categories (low vs. high). Experience of suicidal ideation, planning, and attempt was assessed between the 8th (2013) and 10th wave (2015) of the surveys. After adjusting for confounders including lifetime experience of suicidal behaviors at the 7th wave of the survey (2012) as well as socio-demographic information, the low interpersonal trust group was more likely to experience suicidal ideation (OR: 1.30, 95% CI: 1.11-1.53) compared to the high interpersonal trust group whereas no statistically significant association was observed in the reciprocity analysis.
