Abstract
BackgroundDysfunctional cognitions related to trauma is an important factor in the development and maintenance of post-traumatic stress disorder symptoms in children and adolescents. The Child Post-traumatic Cognitions Inventory (CPTCI) assesses such cognitions about trauma. We investigated the psychometric properties of the Korean version of CPTCI and its short form by surveying child and adolescent survivors of sexual violence.MethodsChildren and adolescents aged 7–16 years (N = 237, Mage = 12.6, SD = 2.3, 222 [93.7%] were female) who were exposed to sexual violence were included in this survey. We assessed the factor structure, internal consistency, and validity of the CPTCI and its short form through data analysis.ResultsConfirmatory factor analysis results supported the two-factor model presented in the original study. The total scale, its subscales, and the short form had good internal consistency (Cronbach’s α = .96 for total scale and .91–.95 for the other scales). The CPTCI showed high correlations with scales measuring post-traumatic stress symptoms (r = .77–.80), anxiety (r = .69–.71), and depression (r = .74–.77); the correlation with post-traumatic stress symptoms was the highest. The differences in CPTCI scores per post-traumatic stress symptom levels were significant (all p < .001) Sex differences in CPTCI scores were not significant (p > .05 for all comparisons); however, the scores exhibited differences per age group (all p < .001).ConclusionsThe results indicate that the Korean version of the CPTCI is a valid and reliable scale; therefore, it may be a valuable tool for assessing maladaptive cognitions related to trauma in research and clinical settings.

Confirmatory factor analysis A confirmatory factor analysis revealed a significant disparity between the model and the observed data regarding the original two-factor model for the full scale: χ2(274, N = 237) = 878.2, p
The results showed that the correlations among Child Post-traumatic Cognitions Inventory (CPTCI) total score, CPTCI-PC, and CPTCISW remained strong
Summary
Dysfunctional cognitions related to trauma is an important factor in the development and mainte‐ nance of post-traumatic stress disorder symptoms in children and adolescents. Considering the need for a valid and reliable instrument to assess trauma-related cognitions, Foa et al [6] developed the Post-traumatic Cognitions Inventory (PTCI). This inventory consists of 33 items that comprise three factors: “negative cognitions about the self,” “negative cognitions about the world,” and “self-blame.”. The inventory was translated and tested on diverse samples in countries such as Germany [8], the Netherlands [9], Korea [10], and Taiwan [11], where its factor structure was repeatedly verified, and its reliability and validity were confirmed In these studies, it was reported that certain characteristics like sex, type of trauma experienced, and cultural background could affect PTCI scores and its psychometric properties
