ABSTRACT
Objective: This study investigated body dissatisfaction, neuroticism, and sex as potential predictors of calorie-tracking app usage amongst undergraduate college students. Participants: College students (N = 491) were recruited from a large northeastern university in October 2015. Methods: Participants completed an online survey asking about their sex, body dissatisfaction, neuroticism, and use of apps that track calories. Results: Analyses revealed that female sex and body dissatisfaction—but not neuroticism—were direct predictors of calorie-tracking app usage. Analyses also provided support for a causal sequence wherein neuroticism and body dissatisfaction mediate, in serial, the relationship between female sex and calorie-tracking app usage. Conclusions: The results from this study suggest that female college students are more likely to use calorie-tracking apps—a phenomenon which may be attributable to their higher levels of neuroticism and subsequent increased body dissatisfaction.

Notes
† The PROCESS v2.16 macro for SPSS does not provide an estimate of the total effect when a model includes a dichotomous outcome variable. Additionally, with a dichotomous outcome variable, logistic regression is used as opposed to OLS regression. Thus, the indirect and total effects are scaled differently, so the total effect cannot be simply calculated as the sum of the direct and indirect effects.35
