Reliability, validity and psychometric properties of the Greek translation of the posttraumatic stress disorder scale

The Greek version of the Davidson Trauma Scale (DTS) was developed to respond to the need of Greek-speaking individuals. The translated questionnaire was administered to 128 HIV outpatients (aged 37.1±9.1) and 166 control patients (aged 32.4±13.4). In addition to the DTS Greek scale, subjects were a...

description The Greek version of the Davidson Trauma Scale (DTS) was developed to respond to the need of Greek-speaking individuals. The translated questionnaire was administered to 128 HIV outpatients (aged 37.1±9.1) and 166 control patients (aged 32.4±13.4). In addition to the DTS Greek scale, subjects were assessed with two other scales useful for assessing validity. For each factor analyses two components were extracted, based on Cattell’s scree test. The two components solution accounted for 55.34% of the total variation in case of frequency variables and 61.45% in case of severity variables. The Cronbach’s alpha coefficient and Guttman split-half coefficient of the DTS scale were 0.93 and 0.88 respectively. The test-retest reliability of the Greek version of DTS scale proved to be satisfactory. Individual items had good intra-class correlation coefficients higher than 0.5, which means that all questions have high levels of external validity. The psychometric strength of interview for posttraumatic stress disorder-Greek version it’s reliable for its future use, particularly for screening subjects with possible diagnosis of posttraumatic stress disorder.
