Multivariate analysis such as factor analysis and "profile analysis" were used to determine the conceptual structure and the contextual and temporal invariants in the Clinical Scales of the Minnesota Multiphasic Personality Inventory-2, MMPI-2, within a sample of psychology students, (n=200), were eliminated, thus the sample was constituted with 168 evaluated students (84% of n=200). It was demonstrated the presence of contextual invariants in the conceptual structure of the MMPI-2 for the Paraguayan sample compared to the Mexican sample, in the saturation of three predominant factors, even in number as in nature. Temporal invariants are also registered as they are observed in the profile analysis of the samples of different academic levels, consistent patterns that point to a defined personality (g factor) in the psychology student with independence of gender, age, levels achieved, relationship status, employment and religion. The intra and intersubject, statistical, descriptive, univariate analyses allow describing and comparing, patterns of career behavior and personality. Indicators are shown for motivational behavior, expectations, assessment of the professional instruction received or currently receiving from the institution. Functional levels in all sample cut-offs are reported in 46% (n=77). Self-controlled disfunction reaches 37% (n=62) and disfunction arrives at a 17% (n = 29). The goals of this study have been accomplished. Methodological and applied derivations from the results are examined.
