Measurement of the Jungian Psychological Types in Mexican university students

Abstract The aim of this study was to measure the eight Psychological Types proposed by Carl G. Jung in Mexican population. A cross-sectional, multicenter, exploratory study was carried out, for which a psychometric instrument based on Jungian typology theory was developed. The Psychological Type Indicator (ITP, for its acronym in Spanish) consisted of 8 subscales (one per psychological type). It was administered to a sample of 1194 participants and validated by the methodological and statistical procedure developed by Reyes Lagunes and Garcia y Barragan. The participants were Mexican university students, ranging from 17 to 40 years (median = 21, IQR = 4; 63% female). The internal consistency of the instrument was determined, obtaining an alpha coefficient of 0.873. An exploratory factor analysis indicated a structure of 10 factors, which together explained 32.672% of the variance. Four of the found factors were consistent with Jungian typology (Introverted Feeling, Introverted Thinking, Extraverted Sensing and Extraverted Feeling). The rest of the factors grouped attributes of this theory, which enable a new way of assessing personality in Mexican population with reference on this model of personality.
