Abstract

This study examined the relationship between executive function (EF) abilities, quality of life (QoL),temperamental qualities (EC: effortful control and NA: negative affect), and Body Mass Index (BMI) in a sample of young adults. Previous studies indicated that deficits in various domains of EF are associated with higher BMI and lower QoL. This study did not find statistically significant differences in EF skills based on BMI. Additionally, in this sample, there were no significant relationships between BMI and QoL. However, interesting relationships emerged between EF skills and NA, as well as EF skills and physical QoL. Furthermore, there is some evidence in this sample that suggests that individuals at either end of the BMI spectrum experience similar levels of executive dysfunction. Further investigation is necessary to determine whether there are indeed similar profiles of executive dysfunction at both very high and very low ends of the BMI distribution.
