Objectives: Preliminary evidence suggests that openness and agreeableness are associated with instrumental activities of daily living (IADLs). However, how personality is related to IADLs remains unclear. This study aims to determine how personality factors predict performance of (IADLs), which it was hypothesised, was because of executive functioning (EF). Methods: Participants were a total of 65 independent community dwelling older adults. Bivariate correlations and hierarchical regressions were completed to determine the associations between openness and agreeableness with IADLs. Lastly, mediation analyses were completed to examine the hypothesis that EF would mediate this relationship Results: Correlation and regression findings support the relationship between openness and IADLs but not agreeableness and IADLs. As hypothesised, the relationship between openness and IADLs was mediated by EF. Conclusions: The research replicated the relationship between openness and IADLs and extend the literature by showing the mechanism of action for this relationship is EF. While the mediation results support this perspective, future research should determine if interventions that increase older adults' EF, in turn, increase or attenuate decline in IADLs over time.
