Background. Given the high prevalence of potentially traumatic events (PTEs), pediatric providers are in a novel position in early identification and referral of the children with PTEs. Yet paucity of culturally adapted instruments to screen PTEs and related symptoms in preschool-aged children limits pediatric providers. This multicenter study aimed to screen the traumatic life events of preschool-aged children admitted to pediatric outpatient clinics at four different cities of Turkey and to determine the socio-demographic risk factors associated with PTEs. Moreover, it was also intended to develop the cultural adaptation of the Child and Adolescent Trauma Screen (CATS) Caregiver-report 3-6 Years version to Turkish and to analyze its reliability.
