Adaptación al castellano de la Centrality of Event Scale (CES)

The “Centrality of Event Scale” (CES) is an instrument used to assess the centrality that a particular event has in the person. Previous studies show that centrality is a construct highly relevant for post-traumatic stress symptomathology, depression and complicated grief. The aim of this study was to adapt into Spanish the CES and obtain evidences of reliability and validity. Two samples consisting of 208 and 320 college students participated in the study. They completed the CES and measures of depression (BDI), anxiety (STAI) and symptoms of post-traumatic stress (PSS). The results agree with those obtained by the original version of the CES, showing high internal consistency (Cronbach’s alpha of 0.92 and 0.94, for each sample) and acceptable test-retest reliability at two months (r = 0.803, p < 0.01). The principal component analysis shows a single explanatory factor that accounted for 45% of the variance. Finally, CES scores show significative relationships with various indicators of psychopathology, and is also a predictor, along with measures of anxiety and depression, of the 32% of the symptoms of post-traumatic stress disorder. The Spanish version of the CES seems to be a valid and reliable measure of the centrality of the event.La “Centrality of Event Scale” (CES) es un instrumento utilizado para evaluar la centralidad que tiene una determinada experiencia en la persona.
