The Relationship between Childhood Trauma and Suicidal Ideation: Role of Maltreatment and Potential Mediators

OBJECTIVE: Childhood trauma is recognized as an important risk factor in suicidal ideation, however it is not fully understood how the different types of childhood maltreatment influence suicidal ideation nor what variables mediate the relationship between childhood trauma and suicidal ideation. This study examined the path from childhood trauma to suicidal ideation, including potential mediators. METHODS: A sample of 211 healthy adults completed the Childhood Trauma Questionnaire (CTQ), Beck scale for Suicidal Ideation (BSI), Functional Social Support Questionnaire (FSSQ) and Hospital Anxiety and Depression Scale (HADS). Path analysis was used to investigate the relationship among study variables. RESULTS: Of the several types of childhood maltreatment we considered, only childhood sexual abuse directly predicted suicidal ideation (β=0.215, p=0.001). Childhood physical abuse (β=0.049, 95% confidence interval: 0.011–0.109) and childhood emotional abuse (β=0.042, 95% confidence interval: 0.001–0.107) indirectly predicted suicidal ideation through their association with anxiety. Childhood neglect indirectly predicted suicidal ideation through association with perceived social support (β=0.085, 95% confidence interval: 0.041–0.154). CONCLUSION: Our results confirmed that childhood sexual abuse is a strong predictor of suicidal ideation. Perceived social support mediated the relationship between suicidal ideation and neglect. Anxiety fully mediated the relationship between suicidal ideation and both physical abuse and emotional abuse. Interventions to reduce suicidal ideation among survivors of childhood trauma should focus on anxiety symptoms and attempt to increase their social support.

Korean Facial Emotion Recognition Tasks for Schizophrenia Research

OBJECTIVE: Despite the fact that facial emotion recognition (FER) tasks using Western faces should be applied with caution to non-Western participants or patients, there are few psychometrically sound and validated FER tasks featuring Easterners' facial expressions for emotions. Thus, we aimed to develop and establish the psychometric properties of the Korean Facial Emotion Identification Task (K-FEIT) and the Korean Facial Emotion Discrimination Task (K-FEDT) for individuals with schizophrenia. METHODS: The K-FEIT and K-FEDT were administered to 42 Korean individuals with schizophrenia to evaluate their psychometric properties. To test the convergent and divergent validities, the Social Behavior Sequencing Task (SBST) and hinting task were administered as social-cognitive measures, and the Trail Making Test (TMT)-A and -B were administered as neurocognitive measures. RESULTS: Average accuracy on the K-FEIT and K-FEDT were 63% and 74%, respectively, and internal consistencies of the K-FEIT and K-FEDT were 0.82 and 0.95, respectively. The K-FEIT and K-FEDT were significantly correlated with SBST and Hinting Task, but not with TMT-A and B. CONCLUSION: Following replication studies in a larger sample, the K-FEIT and K-FEDT are expected to facilitate future studies targeting facial emotion recognition in schizophrenia in Korea. Limitations and directions for future research are discussed.
