Neuroticism also refers to the degree of emotional stability and impulse control and is sometimes referred to by its low pole, "emotional stability".

This model was defined by several independent sets of researchers . These researchers began by studying relationships between a large number of known personality traits . They reduced the lists of these traits (arbitrarily) by 5--10 fold and then used factor analysis to group the remaining traits (using data mostly based upon people's estimations, in self - report questionnaire and peer ratings) in order to find the underlying factors of personality . </P> <P> The initial model was advanced by Ernest Tupes and Raymond Christal in 1961, but failed to reach an academic audience until the 1980s . In 1990, J.M. Digman advanced his five - factor model of personality, which Lewis Goldberg extended to the highest level of organization . These five overarching domains have been found to contain and subsume most known personality traits and are assumed to represent the basic structure behind all personality traits . </P>
