La faceta Orden del dominio Concienciación del Modelo de los Cinco Factores de la personalidad normal describe la tendencia de las personas a mantener su entorno personal organizado y ordenado, así como a establecer y seguir un horario de tareas. En investigaciones anteriores, se construyó una escala de 9 ítems para su medición y se calibró con el Modelo de Respuesta Gradual de la Teoría de Respuesta al Ítem. En el presente estudio, se realizan simulaciones de pruebas adaptativas para obtener una medida eficiente de la faceta. Participaron 441 sujetos de población general (51% mujeres) que respondieron a todos los ítems de la escala de Orden. Se utilizó el programa Firestar para programar el algoritmo que simula la administración adaptativa. Se compararon dos criterios para detener la administración: a) tras administrar 4 ítems y b) tras alcanzar un error de estimación del rasgo de 0,35 o responder a 5 ítems. Las correlaciones entre las estimaciones de rasgo obtenidas con la escala completa y las versiones adaptadas fueron altas (r > .89). Los resultados favorecieron ligeramente el modo de administración adaptado que planteaba un criterio de parada mixto.

SIMULATIONS OF ITS ADAPTIVE MEASUREMENT The Order facet of the Concientiouness domain of the Five Factor Model of normal personality describes people’s tendency to keep their personal environment organized and neat, as well as to set up and follow a task schedule. In previous research, a 9-item scale was constructed for its measurement and calibrated with the Graded Response Model of Item Response Theory. In the present study, adaptive testing simulations are performed to obtain an efficient measure of the facet. A total of 441 general population subjects (51% female) participated and responded to all items of the Order scale. The Firestar program was used to program the algorithm that simulates adaptive administration. Two criteria for stopping the administration were compared: a) after 4 items were administered and b) after an error of trait estimate of 0.35 was reached or 5 items were answered. Correlations between trait estimates obtained with the full scale and the adapted versions were high (r > .89). The results slightly favored the adaptive mode of administration that posed a mixed stopping criterion. Keywords Order Facet - Five Factor Model - Adaptive Testing
