Abstract
Traumatizing experiences significantly impact mental health outcomes, underscoring the need for a concise yet comprehensive assessment tool. The(GPS) was developed to address this gap. Although the GPS has been translated into over 30 languages, including Greek, its cross-cultural validity remains unexamined.The aim of this study was to evaluate the validity and reliability of the Greek GPS.Study 1 involved 1418 participants who completed an online questionnairewhich assessed trauma-related symptoms using the GPS,, the, the, the, theand the. The dataset from Study 1 was utilized for exploratory factor analysis. Study 2 included a dataset of 971 participants drawn from the Greek adaptation of the CARTS protocol, which was used to conduct confirmatory factor analysis.The results showed satisfactory internal consistency as well as test-retest reliability, convergent and divergent validity of the GPS. The exploratory and confirmatory factor analyses supported a univariate structure of the GPS-Symptoms, with all symptom items exhibiting moderate to high loadings on the underlying factor and the solution accounting for 63.6% and 48.1% of the total variance in study 1 and study 2, respectively, and the univariate model fit indices being(112)  282.349,  .001, CFI = . 947, SRMR = .039, RMSEA = .040 [90% CI: 0.34-0.045], ECVI = .376 [90% CI: 0.33-.43]. All risk factors were significantly related to each of the GPS-Symptoms. Regression analyses revealed that gender and risk factors significantly predicted GPS-Symptoms.The current study provides preliminary evidence supporting the use of the Greek GPS as a valid and reliable tool for assessing transdiagnostic symptoms following trauma exposure.
