ResumoThe impact of event scale and the revised version (IES-R) have been used to assess cases with anxious disorders. The main objective in this study is to analyse the psychometric properties in the IES-R Spanish version, and to determine the cut-off score to detect cases with high level of di stress. A total of 193 out-patients cancer completed the IES-R, and were assessed throl.!gh a psychlatric in terview. We did an exploratory fa cton'a I analysls to evaluate the Internal structure in this scale, and a conflrmatory factorial analysis to determine the adjustment goodness of the dimensionality in thls scale. The discrlminatoryexactitude of a scale for a cut-off score is determlned through the receiving operate curve (ROC). In patients wlth cancer, the model with fit adjustment goodness ís composed by two dimenslons: intruslon/ hyperactivation and avoidance (X2=166, 11; g.I:188), that explain 39,77% o, the total variance. With the ROC ahalysls, the sensibility and specificity scores not offer an acceptable accuracy in the cut-off scores to detect cllnical cases. The differeríces in the mean companson between the total score of the IES-R in patients with psychiatric disorders (X=20,08; DS=1,27) and non-psychiatric diagnosis (X= 14, 4; DS=0,88) were signiflcant (T=3,78;P
