Psychometric properties of the cumulative trauma scale: evaluation of the validity and reliability in a Turkish sample

Eltan, Selen
Stressful life events leading to traumatic reactions are noteworthy, and trauma studies generally consider one traumatic event which an individual experienced recently or affected most dramatically. However, cumulative impacts of traumas are also necessary to focus especially in the cultures in which traumatic events are common. The main aim of the current study is to adapt the Cumulative Trauma Scale-Short Form (CTS-S) into Turkish and to investigate its psychometric properties to use in trauma-related researches. In the adaptation process, the scale was translated into Turkish, and clarity of scale was checked. The study sample consisted of 384 participants who have at least one traumatic experience and older than 18 years, recruited through snowball sampling. For examining the reliability of the CTS-S, interrater and internal reliability analyses were conducted. For the validity purposes, correlation analyses were run between the CTS-S and concurrent and discriminant validity scales. Moreover, the most commonly and most frequently experienced traumatic events in Turkish culture were investigated, and gender differences were highlighted. A result of the current study revealed the adapted version of the CTS-S is a reliable and valid instrument. Furthermore, male and female samples were found to be experienced different traumatic events in terms of occurrence and frequency, and evaluation of these events varied across gender. The findings of the present study were discussed in line with related literature and the original study of the CTS-S. Finally, the strengths and limitations of this study were presented, and suggestions for further research were pointed out.
