The aim of the study was to identify the predictive role of anxiety sensitivity (SA) and negative affect (AN) on anxiety and depression, a relationship that has not been analyzed in detail. A multivariate correlational study was carried out with structural equations. The sample included 506 participants (M = 31.96, SD = 11.26 years). Significant correlations were reported between the transdiagnostic variables and the symptoms, with wide differences once the AN was controlled. The regression coefficients showed a high predictive capacity of SA and AN, especially with anxiety. In a structural model, a favorable adjustment without evidence of AN mediation in the SA and symptoms. The possibilities of AN and SA are discussed as second-order variables that suggest a higher order model.

El objetivo del presente estudio fue identificar el papel predictivo de la sensitividad ansiosa (SA) y el afecto negativo (AN) de los síntomas ansiosos y depresivos, relación que no ha sido analizada con detenimiento. Se realizó un estudio correlacional multivariado con ecua-ciones estructurales en un diagrama de senderos. La muestra fue no probabilística de 506 participantes (M = 31.96, DE = 11.26 años). En los resultados se reportaron correlaciones significativas entre las variables transdiagnósticas y los síntomas, con diferencias amplias una vez controlado el AN. Los coeficientes de regresión jerárquica evidenciaron alta capacidad predictiva de la SA y el AN, en especial con los síntomas ansiosos. En un modelo estructural se presentó un ajuste favorable, sin evidencias de mediación del AN en la relación SA y síntomas. Se discutieron las posibilidades de un AN y SA como ...
