Neuroticism is a longitudinally and culturally robust measure of emotional stability that emerges as a key dimension in almost all personality systems since proposed by Eysenck (Eysenck and Eysenck, 1975). The various manifestations of neuroticism in different assessments have been shown to exhibit considerable overlap (Aluja et al., 2002; McCrae et al., 1985; Zuckerman et al., 1993) and the trait is quite stable over many years (Wray et al., 2007). Neuroticism can be detected within a variety of different social strata and cultures (Eaves et al., 1989) and may even be recognized in the behavior of other, less complex, organisms (Gosling, 2001; Gosling et al., 2003).
