Posttraumatic growth (PTG) is a positive psychological change experienced after trauma and it has gained global recognition in recent years. The present study aimed to validate a South Korean version of the Posttraumatic Growth Inventory–Expanded (K-PTGI-X) for use with trauma-exposed and bereaved samples. A national sample comprising South Korean adults was used for the analysis. As a result, the 4-factor bi-factor model was best supported in both the trauma and bereaved groups in terms of personal strength, new possibilities, spiritual–existential change, and being able to relate to others. Additionally, the K-PTGI-X showed satisfying reliability, concurrent validity, and discriminant validity. Lastly, regarding the group differences, women showed higher rates of PTG than men and the bereaved group exhibited higher spiritual and existential growth in the PTG than the trauma group. Given these results, implications for adaptation in various fields when assessing and encouraging PTG in practical settings are discussed.

Since suicide is one of the major health problems worldwide, the goal of the present study is to develop a psychometrically sound suicide risk screening tool named Suicide Screening Questionnaire- Self-Rating (SSQ-SR) to quantify the risk of suicidal behavior. The development process includes item generation, item revision and refinement, and validation. A total sample of 2,238 adults in South Korea was used for analysis. The results of factor analysis showed that the SSQ-SR, containing 25 items, supported a three-factor model: “Situational factors,” “Negative self-perceptions and mental health factors,” and “Suicidal thoughts and behaviors.” Also, SSQ-SR showed satisfying internal consistency, concurrent validity and discriminant validity. Lastly, the results of ROC analysis showed a cut-off point of 33.5 for the low-risk group and 36.5 for the high-risk group. Considering these results, the current results demonstrate the SSQ-SR is a valid scale and therefore can contribute to future suicide-related studies and prevention.

This study identifies the stigma experienced by 12 bereaved parents 2 and 5 years after losing a child in the Sewol ferry disaster in South Korea. Using thematic analysis, we categorized the experience of stigma into two components based on Corrigan and Kosyluk’s social cognitive model of stigma: public stigma and self-stigma, and each was analyzed into three types of stigma: stereotype, prejudice, and discrimination. We identified four additional factors related to stigma mitigation. The potential implications for characterizing the experiences of bereaved parents, particularly those facing stigma, are discussed in light of these findings in the longitudinal perspective.
