The aim of the study was to analyse personality determinants related to the level of pro-health-behaviours among
Polish and Spanish physical education students. The study was conducted among 219 Polish and 280 Spanish students,
using the NEO-FFI Personality Inventory as well as the Pro-health Behaviour Inventory by Juczyński. Statistical
analyses were performed using Pearson’s correlation coeffi cient and moderation analysis. Among the prohealth
behaviours, students obtained the highest results in terms of positive mental attitude, and among personality
traits, for extraversion. A signifi cant increase in the general index and some domains of pro-health behaviours
together with an increase of extraversion, conscientiousness, openness and agreeableness, as well as a decrease
in neuroticism, were found among all the students. The moderating infl uence of home country on personality relationships
with health-promoting behaviours was also confi rmed, with an indication towards an the increase in
the general index of health-promoting behaviours and/or individual domains along with the intensifi cation of
agreeableness and conscientiousness, and a decrease along with the increase in neuroticism and extraversion, but
only among Polish students. Regardless of country of origin, the overall index of health-promoting behaviours increased
along with the rise in conscientiousness (notably among Spanish students). Signifi cant relationships between
personality traits and the level of pro-health behaviours have been demonstrated, as well as the moderating
infl uenceof home country on the relationship between these variables among Polish and Spanish physical education
students.
