La escala de Trauma de Davidson (DTS) mide la frecuencia y gravedad del Estrés Postraumático. Dado que en Chile existe escasez de datos respecto de la validez y confiabilidad de instrumentos para medir este trastorno, se examinan las propiedades psicométricas de la escala. Participaron 130 adolescentes de entre 13 y 18 años (M = 15,78; DT = 1,40). Participaron pacientes traumatizados y adolescentes de la población general.
Los participantes respondieron la DTS, una escala de depresión y otra de ansiedad. La DTS obtuvo adecuada consistencia interna, mostró validez convergente (correlacionó de forma moderada, directa y significativa con escalas de depresión y ansiedad) y discriminó entre la muestra clínica y general. La DTS parece ser un instrumento válido y confiable en adolescentes chilenos.
Davidson Trauma Scale (DTS) measures the frequency and severity of the Posttraumatic Stress Disorder PTSD.
Since Chile has limited data about validity and reliability of instruments to measure PTSD, this study evaluated psychometric properties of the scale in a sample of 130 adolescents between 13 and 18 years (M= 15,78; DT= 1,40). Some of them were traumatized patients and others were from general population. They answered the DTS, a depression and an anxiety scale. The scale obtained adequate internal consistency scores, showed convergent validity (DTS score was associated moderately, directly and significantly with depression and anxiety scores), and discriminated between clinical sample and general population. DTS seems to be a valid and reliable instrument in chilean adolescents.
