Abstract
|
BACKGROUND: Suicide in college students is a major public health concern. Suicidal ideation (SI) is associated with childhood trauma, personality, dysfunctional attitudes and depressive symptoms, but how they interact to predict SI remains unclear.
METHODS: Using cross-sectional design and convenience sampling method, a survey was conducted among 565 college students having major depressive disorder (MDD). The Childhood Trauma Questionnaire, Eysenck Personality Questionnaire, Dysfunctional Attitudes Scale and Hamilton Depression Scale assessed participants' psychosocial factors. Chi-square test, t-test, Pearson correlation, and Structural Equation Model were used in data analysis.
RESULTS: Overall, 66.02% of participants with MDD had SI. Those with SI showed significant differences in physical abuse, emotional abuse, physical neglect, emotional neglect, psychoticism, neuroticism, extroversion, dysfunctional attitudes and depressive symptoms compared with those without SI. Childhood trauma, psychoticism, neuroticism, extroversion and dysfunctional attitudes affected SI through chain mediation. In addition, depressive symptoms, psychoticism, neuroticism and extroversion directly affected SI. LIMITATIONS: The convenience sampling method may limit the generalizability of the findings.
RESULTS may be biased due to the self-report nature of the data collection procedure, the number of research subjects and differences in suicide risk assessment. The cross-sectional study cannot be used to infer causality.
CONCLUSIONS: The factors of childhood trauma, personality and dysfunctional attitudes affect SI through chain mediation. In addition, depressive symptoms and personality independently predict the occurrence of SI.
