Therefore, there is a need to better understand their predictors. Personality traits, defined by the five factors model, that is the relatively enduring patterns of thoughts, feelings and behaviors that characterize an individual, are related to these behaviors in non-pathological samples1. For example, higher neuroticism, lower extraversion and openness to experience are related to lower PA. Likewise, higher neuroticism and lower conscientiousness are both associated with SB. However, little is known about the extent to which personality may be related to PA and SB in CPD patients. Thus, this study aimed to examine the association between personality traits and PA and SB in CPD patients.A total of 108 CPD patients were assessed on personality traits, PA and SB.Regressions analysis revealed that high neuroticism is associated with less PA (β=-.22; p <.05). High openness was related with more SB (β=.21; p <.05). We also found association between high agreeableness and less SB during the week (β=-.23; p <.01). Age, sex and educational level were controlled in analyzes.Patient personality is related to their involvement in PA and SB. These results contribute to a better understanding of the factors that could be targeted by interventions directed toward the promotion of a physically active lifestyle in patients with CPD.1.
