Validation of the Ukrainian caregiver-report version of the Child and Adolescent Trauma Screen (CATS) in children and adolescents in Ukraine.

Objective: Emerging research indicates that the ongoing conflict in Ukraine has led to an increased prevalence of war-related posttraumatic stress disorder (PTSD) in children and adolescents. The current study sought to test the psychometric properties of a Ukrainian-translated measure of PTSD for children and adolescents; the Child and Adolescent Trauma Screen (CATS; Sachser et al., 2017).

Method: Participants were an opportunistic sample of = 2,004 parents living in Ukraine who provided data on themselves and one target child in their household as part of The Mental Health of Parents and Children in Ukraine Study. The latent structure of the parent-reported CATS was tested using confirmatory factor analysis, composite reliability estimates were estimated, and criterion validity was assessed.

Results: The latent structure of the parent-reported CATS was best reflected by a three-factor model and a four-factor model in the preschool and child and adolescent samples, respectively. Estimates of internal reliability were high for both samples. Criterion validity was supported through associations with external measures of internalizing, externalizing, and attention problems. Parent-report child milestone development delays and prior psychological or pharmacological support were associated with higher average scores on the CATS symptom scales. The prevalence of probable PTSD for the preschool sample was 15.4% ( = 77) and the prevalence of probable PTSD for the child and adolescent sample was 14.4% ( = 217).

Discussion: This study supports the psychometric properties of the Ukrainian parent-reported CATS which can be used routinely in clinical practice for the caregiver-rated assessment of PTSD. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
