Adaptación mediante el modelo de Rasch de tres medidas para estimar la decisión e indecisión de carrera y la ansiedad decisional.

La transformacion del mundo laboral, determinada por los avances tecnologicos, y la velocidad cada vez mayor en la que se transforman las ocupaciones actuales, un numero creciente de personas se enfrentan a la necesidad de familiarizarse con nuevas profesiones e industrias, las cuales podrian ofrecer nuevas oportunidades de empleo y perspectivas de carrera. En funcion de ello, resulta sumamente relevante que los orientadores de carrera cuenten con herramientas adaptadas, acordes al contexto actual, que les permitan lograr mejoras en el proceso de eleccion de carrera, por lo que el objetivo del presente estudio fue adaptar tres medidas, de amplio uso internacional y adecuadas propiedades psicometricas, que permiten estimar el nivel de decision e indecision de carrera y de ansiedad decisional, a la poblacion hispanohablante. La muestra estuvo compuesta por 658 estudiantes argentinos, de los cuales 365 (55.5%) fueron de sexo femenino y 292 (44.4%) de sexo masculino, con edades comprendidas entre 15 y 19 anos ( M = 16.56;  DE = .754), pertenecientes a escuelas tanto publicas (32.8%) como privadas (67.2%). Se realizo un analisis factorial exploratorio y se aplico el modelo de escala de clasificacion, derivado del modelo de Rasch, para evaluar las propiedades psicometricas de las escalas. A partir de los resultados se obtuvieron tres medidas con propiedades psicometricas adecuadas. Dichos instrumentos podran ser utilizados por profesionales de orientacion vocacional con el objetivo de realizar diagnosticos mas precisos y disenar intervenciones que permitan fomentar un adecuado proceso de eleccion. Adaptation of three measures to estimate career decision and indecision and decisional anxiety using the Rasch model Abstract The transformation of the current work-force determined by the technological advances affects and presents new challenges to the career decision-making process. As a result, and given the increasing speed at which current occupations are transformed an increasing number of people face the need to become familiar with new occupations and industries which could offer new employment opportunities and career perspectives. Based on this, it is extremely important that career counselors count on adapted tools to enable them achieve some improvement in the decision-making process; therefore, the main purpose of this study was to adapt three widely used measures and with adequate psychometrics properties to assess the level of career decision or indecision and the decisional anxiety within the Spanish-speaking population. The sample consisted of 658 Argentine students who attended high school, 365 of which (55.5%) were female and 292 (44.4%) male, aged between 15 and 19 years ( M = 16.56; SD = .754), belonging to both public (32.8%) and private (67.2%) schools. An exploratory factor analysis was carried out and the classification scale model,- derived from the Rasch model-, was applied to evaluate the psychometric properties of the scales. From the results the factorial structure of the scales was confirmed and three measures with adequate psychometric properties were obtained. These instruments may be used by career counselors to optimize the career decision-making process. The practical and methodological implications are discussed as well as the limitations of the present study.
