Serial Multiple Mediation of Depressive Symptoms, Thwarted Belongingness, and Perceived Burdensomeness in the Relationship Between Personality Traits and Suicidal Ideation Among Nursing Students: A Cross-sectional Questionnaire Survey

The findings indicate that nursing students exhibit high levels of suicidal ideation, which are influenced by their Big Five personality traits. This relationship appears to be serially mediated by depressive symptoms, thwarted belongingness, and perceived burdensomeness, aligning with the Interpersonal-Psychological Theory of Suicide. Therefore, interventions focused on reducing depressive symptoms in nursing students with vulnerable personality traits may help mitigate feelings of thwarted belongingness and perceived burdensomeness, ultimately reducing suicidal ideation.
