Objectives: Literature suggests that college (ie, post-secondary) students experience food insecurity (FI) at alarming rates. However, the commonly used FI questionnaires have undergone limited evaluations for accuracy in this sub-population. The objective of this exploratory study was to evaluate if FI estimates among college students differ by survey distribution modality. Methods: A test-retest study was conducted from October to December 2017. A random sample of undergraduate students (N = 343) participated in an online survey. After completing the survey, a random sample of these students (N = 66; 29%) completed the same items in paper-and-pencil format. Responses were compared with percent agreement and kappa (κ) coefficients. Results: Students were less likely to affirm each item on paper-and-pencil questionnaires. Percent agreement ranged from 71.2% to 96.9% across items, and κ coefficients ranged from poor to fair. FI prevalence differed by 15% between online and paper-and-pencil assessments (40.9% and 25.8%, respectively). Percent agreement for FI categorization was 75.8% and κ=0.47. Conclusions: Differing survey modalities resulted in varying FI classifications in a sample of undergraduate students. Though limited by size and representativeness, this supports the need for further testing of FI surveys, as accurate FI estimates are essential to serving college students. [ABSTRACT FROM AUTHOR]

Objective To evaluate the feasibility of a grocery store tour for parents and their adolescents being led by adults or adolescent peers. Design Randomized controlled pilot study with surveys at baseline and post-program, and at 3- and 6-month follow-up. Setting Midwestern midsized grocery stores. Participants Sixty-one parents and their 71 11- to 14-year-old adolescents. Intervention Nutrition education during 1 90-minute grocery store tour. Main Outcome Measures Process observations and participants' tour perceptions provided fidelity outcomes. Questionnaires quantitatively assessed participants' knowledge, self-efficacy, and tour strategy use. Analysis Chi-square and McNemar tests were used to analyze categorical data, and Kruskal–Wallis, Wilcoxon signed-rank, and Mann-Whitney U tests were employed for continuous variables (significance at P < .05). Results Over 90% of tour tasks were rated as completed well for adult and peer leaders. Participants had positive tour perceptions but noted deficiencies in teen leaders' knowledge and leadership skills. Overall, parents and adolescents retained increased self-efficacy from pre-tour to post-tour intervals. Despite limited knowledge retention, parents reported they had increased (6.5 ± 4.19) healthful grocery shopping behaviors in the 6 months after the intervention. Conclusions and Implications Peers may feasibly lead grocery store tours but they may need additional resources and support to be highly effective. [ABSTRACT FROM AUTHOR]
