The Impact of Grit on Health Outcomes in College Students

Abstract

Objectives: The objective was to examine the relationship between grit and health outcomes in college undergraduate students. Methods: A cross-sectional convenience sample of college undergraduate students completed an online survey assessing Health-Related Quality of Life (HRQOL), the National Cancer Institute Fruit and Vegetable Screener, and the 2-item Hager Food Insecurity Screener. Grit was assessed by generating a mean score using the 8-item short grit scale. Independent t-tests were used to compare health outcomes between students who reported above/below the average grit score of the sample. Chi-square tests were used to examine group differences between grit level and prevalence of food insecurity. Results: Participants (N = 655) were 19.8 ± 1.5 years old, mostly female (63%), and white (84%). The average grit score was 3.27 ± 0.54 out of 5. Results indicated that students who were grittier than average (n = 372) reported fewer days/months (d/m) with poor mental health (8.1 ± 8.5 vs. 11.6 ± 9.6, P < 0.001), fewer d/m feeling sad/depressed (6.2 ± 7.7 vs. 9.9 ± 9.3, P < 0.001), more d/m with restful sleep (12.9 ± 9.8 vs. 10.3 ± 8.6, P < 0.001), more d/m feeling very healthy and full of energy (12.6 ± 8.8 vs. 8.4 ± 7.5, P < 0.001), and ate more servings of fruits and vegetables per day (2.4 ± 1.3 vs. 2.1 ± 1.32, P < 0.01). Grittier participants were also less likely to report being food insecure (16.0%) vs. less grittier participants (23.3%), P < 0.05. Conclusions: This data indicates that students who were grittier than average reported better HRQOL, consumed a more healthful diet, and were more likely to be food secure. This provides justification for future research to explore grit as a mediating factor that may contribute to better health outcomes, especially in populations particularly susceptible to experiencing poor HRQOL and food insecurity.
