Test development.

There is psychology a variety of theories that can conceptualize personality (Cervone and Pervin, 2008). Among them is the theory of the traits that has been the subject of major advancements of the last two decades (Morizot and Miranda, 2007). According to this conceptualization, personality is composed of traits, universal in humans, on which individuals vary. Thus, all possess equal bipolar traits on which they differ quantitatively. For example, everyone has some level of extraversion, whether high or low (introversion), but it is impossible to qualify a person on this characteristic. The lines reflect the cognitive styles, emotional, relational, experiential, motivational and attitudinal relatively stable over time and across situations, which distinguish individuals.
The IPLC was built on this basis and has a valid and reliable measure of these characteristics.

IPLC and Social Desirability
During the development of the IPLC, a group of people responded to the IPLC and a short version of the Social Desirability Scale Marlowe-Crowne. Significant correlations were observed between the scale of social desirability and traits Emotional stability (r = 0.41; p <0.01), Agreeableness (r = 0.35; p <0.01) and Conscientiousness (r = 0.32; p <0.01), which is in line with the results of the meta-analysis Ones et al. (1996) and the assumption that people with a personality profile more «positive» would get higher results with social desirability scales (McCrae and Costa, 2010). Thus, the social desirability scales do not indicate the tendency to misinterpretation of his own personality or to be in a favorable light, but rather indicate, substan- tively speaking, the trend towards pro-social behavior and to act conformity to social norms (Borkenau and Zaltauskas, 2009).
