Abstract

The Continuous Traumatic Stress Response scale (CTSR) was designed to measure symptoms associated with multiple ongoing security threats in the context of Israeli-Palestinian conflict. Since 2014, Ukraine has faced armed invasion and war, with nationwide insecurity since February 2022. This study aimed to adapt the CTSR scale into Ukrainian and evaluate its psychometric properties within a Ukrainian sample during the ongoing war. The Ukrainian adaptation of the CTSR followed the procedure used in creating the original instrument (Goral, A., Feder-Bubis, P., Lahad, M., Galea, S., O'Rourke, N., & Aharonson-Daniel, L. (2021). Development and validation of the Continuous Traumatic Stress Response scale (CTSR) among adults exposed to ongoing security threats. , (5), e0251724). To identify a unique context-specific factor structure relevant to the Ukrainian experience, the initial 25 items were tested in a sample of 584 Ukrainians using exploratory and confirmatory factor analyses. Subsequently, the established scale structure was assessed for homogeneity, and convergent validity using measures of depression (PHQ-9), anxiety (GAD-7), perceived stress (PSS-4), resilience (BRS), and PTSD symptoms (PCL-5). A three-factor, 9-item solution, representing the constructs of exhaustion, alienation, and helplessness, demonstrated the most acceptable fit among all the alternative CTSR models, including the original: χ = 72.84, df = 24, < .001, χ/ (df) = 3.04, CFI = 0.94, TLI = 0.91, SRMR = 0.05, RMSEA = 0.08. Cronbach's α for internal consistency ranged from 0.68 to 0.84 for total score, and subscales. Significant positive correlations ranging from 0.41 to 0.67 with symptom severity of depression, anxiety, perceived stress, and PTSD established the convergent validity of the Ukrainian CTSR, indicating that it measures related yet distinctive psychological phenomena of reactions to continuous traumatic stress. The revised Ukrainian version of the CTSR scale is a reliable and valid measure of continuous traumatic stress response, accurately reflecting its manifestation in the Ukrainian context. These findings are crucial for guiding clinical interventions and research in prolonged war environments, where understanding the nuances of ongoing trauma is essential.
