Factor Structure of Items from the Personality Adjective Check List in a Sample of Normal Adolescents

Abstract

We present the results of a principal-components analysis of the Personality Adjective Check List (PACL) at the item level, rather than at the scale level. The PACL was constructed by Strack (1987) to evaluate the personality scales proposed by Millon (1981). Data were obtained from a sample of normal adolescents. A scree test was applied to determine the number of factors to be extracted, and the retained factors were then rotated using a varimax procedure. Using the data from this second analysis, congruence coefficients were calculated by correlating the factor weights from the two analyses of men and women. Results reveal the existence in the whole sample of five unipolar personality factors, which we have called: Aggressive, Conscientious, Inhibited, Impulsive and Gregarious. These are not similar to those obtained from a sample of normal adults.Se presentan los resultados de un análisis de componentes principales del Personality Adjective Check List (PACL) al nivel de los ítems en vez del nivel de escala. El PACL fue construido por Strack (1987) para evaluar las escalas de personalidad ropuestas or Millon (1981). Los datos se obtuvieron de una muestra de adolescentes normales. e aplicó una prueba scree ara determinar el número de factores a extraer, y los factores etenidos se rotaron con el procedimiento varimax. Empleando os datos de este segundo nálisis, se calcularon los coeficientes de congruencia al correlacionar los pesos factoriales e los os análisis de varones y mujeres. Los resultados revelan la existencia en toda a muestra de cinco factores unipolares de ersonalidad, que hemos denominado: Agresivo, concienzudo, Inhibido, Impulsivo y Gregario. No se parecen a los factores obtenidos de una muestra de adultos normales
