Abstract
PDF - Background
Suicide among military personnel is a critical issue that threatens both individual well-being and organizational readiness. Despite a growing body of literature on military suicide in Korea findings remain inconsistent owing to differences in study design, participant characteristics, and measurement tools.
Methods
This meta-analysis examined risk factors for suicide among Korean military personnel. Twenty-nine theses and journal articles published between 2000 and 2025 that reported correlation coefficients (r) and met the inclusion criteria were analyzed. Sixty-two variables reported in at least three studies were extracted and categorized into 11 factors depression, trauma experience, military stress, interpersonal relationships, anxiety, general stress, job stress, impulsivity, drinking problems, age, and rank.
Results
Depression, trauma experience, and military stress showed medium- to- large effect sizes, whereas impulsivity and drinking problems demonstrated small but significant effects. High heterogeneity was observed, likely because of differences in military ranks, research designs, and measurement instruments. Publication bias analysis using the trim-and-fill method revealed no missing studies.
Conclusions
This meta-analysis integrated existing findings on suicide risk factors among Korean soldiers and identified the relative importance of key predictors. The results contribute to a better understanding of the psychological and organizational determinants of military suicide and provide practical implications for prevention strategies and future research.

Abstract
PDF
- Background
Internalized shame, defined as the enduring incorporation of shame as a trait due to repeated experiences of shame, is considered a core emotion in individuals with borderline personality traits. It is closely related to self-destructive behaviors, such as self-harm and suicidal ideation. This study aimed to investigate whether internalized shame mediates the relationship between borderline personality traits and suicidal ideation.
Methods
Self-report questionnaires were administered to 303 undergraduate and graduate students to assess borderline personality traits, suicidal ideation, internalized shame, depression, impulsivity, and history of suicide attempts.
Results
Internalized shame mediated the relationship between borderline personality traits and suicidal ideation, even after controlling for known predictors of suicidal ideation, including depression, impulsivity, history of suicide attempts, sex, and age. Specifically, higher borderline personality traits were associated with stronger feelings of shame, which in turn increased suicidal ideation.
Conclusions
These findings suggest that addressing internalized shame could be a key target for interventions aimed at reducing suicide risk in individuals with borderline personality traits.

Abstract

- Background
Communicating the objective meaning of the cut-off criteria for high-risk among suicide risk assessment tools is challenging because they measure different aspects of suicide risk. This study aimed to provide comparable scores among widely used suicide assessment instruments by using test linking.
Methods
Linking was performed using the equipercentile method with the data of 400 adults. Then, for an independent sample of 165 adults, the validity of linking was tested by providing an overall percent agreement of group classification.
Results
Linking results indicated that the score of 4 on the C-SSRS corresponded to 8 on the DSI-SS and 16 on the SBQ-R, respectively. The overall percent agreement of group classification based on the cutoff score of 4 on the C-SSRS was high in both scales, supporting the validity of linking.
Conclusions
The study results provide comparable criteria for the high-risk group among the three measures. Mental health practitioners could utilize our results in identifying people at high suicide risk.
