Thirteen studies were reviewed to better understand how smartphone ownership and use relate to the five factors of personality (i.e., openness, conscientiousness, extraversion, agreeableness, neuroticism) overall and across three different age groups. Of the 10 studies used to compare problematic smartphone use across age groups, 2 (20%) included adolescent samples, 7 (70%) included young adult samples, and 3 (30%) included adult to older adult samples. Across all samples, problematic smartphone use correlated most strongly with neuroticism (positively) and conscientiousness (negatively). Relatively weaker and more inconsistent correlations with problematic smartphone use were found for openness, extraversion, and agreeableness. Future research should emphasize sampling adolescent and older adult populations, as well as measure the six facets of each personality factor to more thoroughly explore potential links between personality and problematic smartphone use
