ObjectiveaaThe aim of the present study was to examine the psychometric properties of the Korean Verbal Abuse Questionnaire (K-VAQ) that consists of 15 items related with life-time verbal aggression exposure. MethodsaaA total of 5814 university students who agreed to take part in the study completed the K-VAQ, the Korean version of the Life Event CheckList (LEC-K) and Impact of Event Scale-Revised (K-IES-R). Internal consistency was checked by using item-total item cor-relation and Cronbach’s alpha coefficient. Exploratory and confirmatory factor analyses were performed, and convergent and concurrent validity levels were examined. Finally, a cluster analysis was conducted to verify the validity of the cutoff point of the K-VAQ. ResultsaaThe Cronbach’s alpha correlation coefficient was 0.9. The K-VAQ showed a single factor structure which explained 55.34 % of the total variance. The K-VAQ was significantly associated with the LEC-K (r=0.24) and K-IES-R (r=0.28), indicating good convergent validity and concurrent validity. The cluster analysis provided four clusters of trauma experiences: high, moderate, low, and minimal, with K-VAQ ranges of 43–81, 20–42, 7–19, and 0–6, respectively. In a further investigation, a K-VAQ score of 40 was found to be the ap-propriate cutoff point to delineate the highly verbally abused group, as used in the previous studies. A sum of 36.5 % of the highly verbal-ly abused group reported to show substantial symptoms of PTSD (K-IES-R score>22). ConclusionaaThe present findings suggest that the K-VAQ has good psychometric properties for assessing verbal aggression among the Korean population. Psychiatry Investig 2015;12(2):190-19
