Abstract

RINCON, Paulina et al. Psychometric Properties of the Children's PostTraumatic Symptoms Scale in the Earthquake and Tsunamis Chileans' Victims. Ter Psicol [online]. 2014, vol.32, n.1, pp.57-64. ISSN 0718-4808.  http://dx.doi.org/10.4067/S0718-48082014000100006.

There are not many instruments about evaluation of post Traumatic symptomatology in Latin-American children and adolescents. The current study analyzes the psychometric properties of the child PTSD Symptom Scale CPSS (Foa, Johnson, Feeny y Treadwell, 2001), among young victims of a natural disaster. Regular psychometric analyses were carried out, including an exploratory and confirmatory factor analysis of the instrument. The structured interview DISC-IV was used as a criterion test. An structure of three first order factors showed the best fit. The scale presented high internal consistency. A score of 24 or more points allowed a sensitivity of 82% and a specificity of 88% according to DISC-IV. These positive psychometric qualities indicate the utility of this scale to be used in chilean children and adolescents.

Keywords : confirmatory factor analysis; CPSS; natural disaster; DISC-IV; psychological assessment.
