espanolLa presente investigacion tiene como proposito analizar las propiedades psicometricas de la Escala de Autoeficacia percibida especifica de situaciones academicas en una muestra de 297 estudiantes universitarios de distintas facultades y carreras pertenecientes a una universidad chilena. Para lograr el objetivo mediante un estudio psicometrico po r procedimientos confirmatorios se realizo un analisis factorial confirmatorio (AFC), analizando la propuesta unidimensional realizada con estudiantes de educacion secundaria de chile. Se evaluo la consistencia interna de la escala mediante el Alfa ordinal . Los resultados obtenidos con la muestra de estudiantes universitarios indican una buena fiabilidad interna del instrumento (alfa ordinal=.87), asi mismo los datos encontrados apoyan la validez del modelo propuesto. Segun lo anterior la escala para medir autoeficacia percibida especifica en situaciones academicas apoyan preliminarmente su uso con otros estudiantes universitarios en la educacion superior chilena.

The internal consistency of the scale was evaluated using ordinal Alpha. The results obtained with the sample of university students indicate a goo d internal reliability of the instrument (.87), also the data found support the validity of the proposed model.
