Personality Determinants of Diet Health Quality among an Elite Group of Polish Team Athletes

The aim of the study was to analyse personality determinants of diet health quality among of an elite group of Polish team athletes. The correlations between personality traits of the big five model and the indices of diet health quality (the pro-healthy diet index, pHDI-10 and the non-healthy diet index, nHDI-14) were assessed. Research was carried out among 213 athletes (males), using the beliefs and eating habits questionnaire (Kom-PAN) and the neuroticism extraversion openness personality inventory—revised (NEO-PI-R). Statistical analysis was performed with the use of Pearson’s linear and Spearman’s signed rank correlation coefficients as well as multiple regression, assuming the significance level of α = 0.05. It has been shown that the pro-healthy diet index (pHDI-10) decreased with increasing Neuroticism, while an increase was noted along with increasing Extraversion. In the case of the non-healthy diet index (nHDI-14) a decrease along with a simultaneous increase in the level of Agreeableness (p < 0.05). Significant (but weak) correlations have been indicated between personality traits and diet health quality. The identified dependencies may be used to personalise the impact of dietary education among athletes.
