Desarrollo y construcción de las puntuaciones de prevalencia del Inventario Millon de Estilos de Personalidad (MIPS) para la población adulta de la ciudad de Buenos Aries

Resum

Many researchers have assessed individual differences using empirically-derived instruments alone. The lack of theoretically-derived instruments in the field of normal personality led T. Millon to develop the MlPS (Millon Index of Personality Styles, 1994). The MIPS is based on an ecological-
evolutionary theory which proposes an explanation of the development of normal and abnormal personality styles. From the technical point of view, the questionnaire includes prevalence scores instead of other common transformation scores (T scores and percentiles). Prevalence score are based only on comparisons between persons who possess the particular psychological trait, that is to say they do not take into account the entire population in order to derive transformed test scores. Goals: To provide guidelines for constructing plavalence score based on data from the Argentinian population, and to provide cut off scores to make the MIPS a useful assessment tool. Subjects: The sample comprised 450 males artd 489 females aged between 18 and 65, stratified for age and educational level in accordance with National Census data. Results: Enhancing, Modifying and Individuating were the predominant pairs of Motivational aims section. Extraversion, Feeling and Systematizing were the most prevalent cognitive modes. The more adaptive pairs of interpersonal behaviors were the more prevalent. Style response pattern was similar to those reported in normative samples from the US populotion.
