Psychometric properties of the Greek Version of the Traumatic Event Scale (TES) (Version A) among low-risk pregnant women

Abstract

Abstract Background The Traumatic Event Scale (TES) is one of the most often used instruments for the assessment of the Posttraumatic Stress Disorder (PTSD) symptomatology during pregnancy which is linked with adverse effects. The aim of the study was to assess the psychometric properties of the TES (version A) in a sample of Greek pregnant women. Methods Two hundred one low risk pregnant women in their second or third trimester were invited to participate in the study. Participants completed a number of questionnaires including the Greek versions of TES-A, State-Trait Anxiety Inventory (STAI), Coping Orientations to Problems Experienced (Brief COPE), Perceived Stress Scale (PSS-10) and Edinburgh Postnatal Depression Scale (EPDS). Confirmatory factor analysis (CFA) was conducted in order to test how well the already TES-A five-factor model fits the data from Greece. Results Participants’ average age was 34.2 years (SD = 4.3 years). Through CFA the already five-factor structure of the TES-A (Anticipation of trauma, Intrusion, Avoidance, Resignation, Hyperstimulation) was applied to our sample. All five factors were significantly and positively correlated with each other. All Cronbach’s alpha were over 0.7, indicating acceptable reliability of the factors. Relatively convergent validity, all factors of the Greek version of the TES-A were significantly associated with stress, anxiety, depression and coping strategies. Conclusion The Greek version of TES-A is detected to be a valid and reliable instrument of prenatal Posttraumatic Stress Disorder (PTSD) symptomatology among low-risk Greek pregnant women.
