The big five and self-esteem among overweight dieting and non-dieting women.

Overweight is one of the most frequent phenomena, which poses serious health risks, emotional disturbances and esthetic and social problems in the Western world. This study investigated personality differences between women with normal weight, dieting overweight women and non-dieting overweight women. Thirty women with normal weight (NW), 30 overweight women who participated in diet groups (OWD), and 30 overweight women who did not participate in such groups (OWND) filled in a demographic questionnaire, Costa and McCrae's [Costa, P. T. Jr., & McCrae, R. R. (1992). NEO PI-R: Professional manual. Odessa, FL: Psychological Assessment Resources.] NEO-FFI, and Rosenberg's [Rosenberg, M. (1965). Society and the adolescent self-image. Princeton, NJ: Princeton University Press.] Self-Esteem questionnaire. The results indicate that the OWND are significantly more neurotic and less open, conscientious, agreeable, and extravert than the other two groups. Self-esteem of the OWND is also lower than both OWD and NW. Contrary to hypothesis, OWD and NW do not significantly differ from each other with respect to both the Big Five and self-esteem.
