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.
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.
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.
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.
尽管使用西方人脸进行面部情绪识别（FER）任务时应谨慎应用于非西方参与者或患者，但针对东方人的面部表情进行情绪的心理测量学上健全且经过验证的 FER 任务却很少。因此，我们旨在开发和建立适用于精神分裂症个体的韩国面部情绪识别任务（K-FEIT）和韩国面部情绪辨别任务（K-FEDT）的心理测量特性。
对 42 名韩国精神分裂症患者进行 K-FEIT 和 K-FEDT 评估，以评估其心理测量特性。为了测试收敛和发散效度，社会行为序列任务（SBST）和暗示任务被用作社会认知测量，而追踪测试（TMT）-A 和 -B 被用作神经认知测量。
K-FEIT 和 K-FEDT 的平均准确率分别为 63%和 74%，K-FEIT 和 K-FEDT 的内部一致性分别为 0.82 和 0.95。K-FEIT 和 K-FEDT 与 SBST 和 Hinting Task 显著相关，但与 TMT-A 和 B 不相关。
在更大的样本中进行复制研究后，K-FEIT 和 K-FEDT 有望促进未来针对韩国精神分裂症面部情绪识别的研究。讨论了局限性和未来研究方向。
