Qualitative studies suggest that college students with food insecurity (FI) experience stigma and misinterpret some of the USDA Adult Food Security Survey Module (AFSSM) questions, leading to misclassification of food security (FS) status. We aimed to evaluate differences in AFSSM-measured FS status and self-categorized FS status (based on USDA descriptions of the four FS levels) among college students, and to identify differences in the coping strategies and BMI of these students. Data were collected cross-sectionally from a convenience sample via web-based, self-reported surveys. Measured FS, self-categorized FS, coping strategies, and self-reported BMI were key variables of interest. Participants were 1003 undergraduate and graduate students (22.2 ± 4.6 years; 65.7% female). Of the participants measured as food insecure (40.0%), 57.8% self-categorized as food secure (MFI-SFS) and 42.2% self-categorized as food insecure (MFI-SFI). Significantly more MFI-SFI participants were AFSSM-categorized as having very low FS when compared to MFI-SFS participants (71.6% vs. 46.6%, p < 0.05). MFI-SFI participants reported significantly higher BMI (M = 24.7, SD ± 6.0 kg/m2) and coping strategies scores (M = 49.8, SD ± 7.5) when compared to MFI-SFS participants (M = 23.1, SD ± 3.6 kg/m2; M = 46.9, SD ± 7.5, respectively, p ≤ 0.01). Assessment of and interventions to address FI among college students should consider the potential influence of self-perception and students’ interpretation of survey questions.
