We performed a cross-sectional study in 450 nonreferred preschool children aged 4 to 6 years to assess the association between hyperactivity/inattention with adiposity and lifestyle characteristics. Measurements included scores of hyperactivity/inattention, adiposity, objectively measured physical activity, television viewing, and eating habits. Higher scores of hyperactivity/inattention were associated with lower percentage body fat, higher levels of physical activity, and less time spent in sedentary activity (all P .01). However, higher scores of hyperactivity/inattention were also associated with more television viewing and less healthy eating habits (all P .04). Except for some selected eating habits (P .07), those relationships remained significant after adjustment for age, sex, and sociodemographic confounders. To conclude, higher scores of hyperactivity/inattention are linked to different lifestyle characteristics that may in part contribute to a future development of overweight/obesity. Precise mechanisms explaining these associations and possible preventive approaches should be further investigated.

Abstract. The study was designed to investigate the psychometric properties of the French version and the cross-language replicability of the Hierarchical Personality Inventory for Children (HiPIC). The HiPIC is an instrument to assess the five dimensions of the five-factor model for children. Subjects were 552 children aged between 8 and 12 years, rated by one or both parents. At the domain level, reliability ranged from .83 to .93 and at the facet level, reliability ranged from .69 to .89. Differences between genders were congruent with those found in the Dutch sample. Girls scored higher on Benevolence and Conscientiousness. Age was negatively correlated with Extraversion and Imagination. For girls, we also observed a decrease of Emotional Stability. A series of exploratory factor analyses confirmed the overall five-factor structure for girls and boys. Targeted factor analyses and congruence coefficients revealed high cross-language replicability at the domain and at the facet levels. The results showed that the French version of the HiPIC is a reliable and valid instrument for assessing personality with children and has a particularly high cross-language replicability.

This cross‐sectional study was designed to investigate personality in children aged 8–12 years. Children's self‐perceptions were compared to parent's ratings. Parents of 506 children completed the Hierarchical Personality Inventory for Children (HiPIC) and children completed a selection of 38 questions from the HiPIC. Results showed that children aged 11–12 years present higher structural congruence, higher reliabilities and higher mean correlation with parents' description than children aged 8–9 years. Interestingly reliabilities of parents' ratings were also higher for older children. Mean levels were higher in younger children for Imagination in parents' ratings and for Benevolence, Conscientiousness and Imagination, in children's ratings.
