[Relationship between exercise dependence and big five personality].
BACKGROUND
Despite the increased interest in exercise dependence, there is limited research examining the personality characteristics of exercise dependent individuals. Furthermore, researchers examining the relationship between exercise dependence and personality have found inconsistent results. This maybe the result of the varying methods used by researchers to assess exercise dependence and personality.


OBJECTIVE
The purpose of this study was to examine the relationship between exercise dependence and personality, and that determine whether there is an addictive personality type. Participants were 484 university students (M=21.24, SD=3.03), and 322 sport leisure participants (M=30.08, Sd=13.58) who completed multidimensional assessments of exercise dependence and personality.


METHODS
to assess exercise dependence, the EDS-R (French version, Kern, L, 2007, Validation de l'adaptation française de l'échelle de dépendance à l'exercice physique : l'EDS-R Pratiques Psychologiques, 13, 4, 425-441) was undertaken. This scale is based on the DSM_IV criteria for substance dependence which are: withdrawal effects, intention effects, lack of control, time, reductions in other activities, continuance. The D5D was chosen to assess the big five personality dimensions (Rolland, J.-P., & Mogenet, J.-L. (1994). Manuel du système d5d. Paris: ECPA.). These dimensions are: Extraversion, Emotional Stability, Agreeableness, Conscientiousness, and Openness to Experience. To examine the predictive relationship of personality for exercise dependence symptoms, a series of multiple regressions was carried out.


RESULTS
Results show that, according to the status of the people under scrutiny, it is either openness to experience and emotional stability or openness to experience and agreeableness which explain the greatest variance of exercise dependence. Then, the description of a personality type seemed very difficult to obtain. We feel it's important to know the personality type, but not sufficient; it is more pertinent to know the type of personality. Then, further research could examine the relationship between personality disorder and exercise dependence. In contrast with the literature, we did not find a relationship between exercise dependence and extraversion.
