The paper entitled “Study on the Psychologist’s Personality Traits” is part of our PhD Thesis and we would like to present the preliminary data of this study. In the first part of this paper we presented the general and theoretical aspects regarding the specific personality traits one should have if becoming a psychologist. We also brought into discussion the problem of working as a psychologist, what exactly this profession implies, taking into account both the influence of the historical context upon the Romanian psychological domain and a few elements of the deontological code of the Romanian psychologist. We presented the theoretical background of the personality traits: the “Big-Five” model, the personality questionnaires and their elaboration process, including also the pattern-making ways of personality which can be approached by these questionnaires. Moreover, we considered several published researches on the psychologist’s situation in Romania after 1990. Concerning the possibility of attaining the objectives and hypotheses proposed, we initiated a pilot study consisting of 50 subjects, of which 25 psychologists, following a Master Programme in Psychotherapy within the Faculty of Psychology, Titu Maiorescu University, and 25 non-psychologists following a Master Programme in other domains (The Academy of Economical Studies). The mean of the approximate age of the two groups of subject is 27. The investigation methods were MBTI, Big-Five (ABCD-M), QMEE and the CPI scales. The results from the Myers-Briggs Type Indicator, revealing the psychological types among the group of the pilot study, are the following: regarding the dominant function, the psychologists make use of three functions in equal proportions, 20% ES and IS, namely Extravert or Introvert Sensing, as well as 20% the EN function, Extravert Intuition, necessary in this profession; regarding the decision-making process, 24% of the psychologists prefer SJ – Sensing and Judging and another 24% prefer NP – namely Intuition and Perceiving; regarding the personality traits, we found a positive correlation between two of the CPI scales, Intellecual Efficiency and Psychological Intuition, which brings us to the conclusion that the more intuitive the psychologist, the more efficient he is.
