Se detallan las propiedades psicométricas de una Prueba de Analogías Figurales desde el marco de la Teoría de Respuesta al Ítem. Se elaboraron 36 matrices de figuras de 2x2 utilizando reglas de emplazamiento, distorsión y número.Se contó con una muestra de 499 estudiantes de Psicología de la Universidad de Buenos Aires, 79% de los cuales fueron mujeres. Se utilizó el Modelo Logístico de 3 Parámetros logrando un ajuste global altamente satisfactorio al 5% (p = .47). Sólo 3 ítems del total no ajustaron al modelo. Existe una buena potencia discriminatoria general (a: M = 1.02; DT = .33), un nivel de dificultad medio (b: M = -.03; DT = .63) y un nivel de acierto por azar ligeramente inferior a lo esperable con 6 alternativas de respuesta (c: M = .14; DT = .05). Se discuten las condiciones para modelizar la Prueba y posibles desventajas del presente estudio.Palabras clave: Analogías; Matrices; Teoría de Respuesta al Ítem.The psychometric properties of a Figural Analogies Test are described within the framework of Item Response Theory. Thirty-six 2x2 matrix figures were constructed by using location, distortion and number rules. The sample included 499 psychology students from the University of Buenos Aires, 79% of whom were women. The 3-Parameter LogisticModel was used obtaining a highly satisfactory global fit at 5% (p = .47). Only 3 items did not fit the model. It had good overall discriminatory power (a: M = 1.02, SD = .33), a medium level of difficulty (b: M = -.03, SD = .63) and the c level was slightly lower than expected with six possible answers (c: M = .14, SD = .05). The conditions for modelling the test and possible disadvantages of the present study are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
