  1. Notes: Values are mean ± standard deviation or n (%); a, b, c denote statistically significant post hoc differences; BMI = Body Mass Index; ecSI/LI = ecSatter Inventory for Low-Income; EDI-3 = Eating Disorders Inventory-3; EFNEP = Expanded Food and Nutrition Education Program; TFEQ = Three-Factor Eating Questionnaire; all measures are self-reported.
  2. 1N = 507 except where noted.
  3. 2p-value for chi-square or analysis of variance comparing eating competence tertiles.
  4. 3Pearson correlation coefficients between total ecSI/LI score and row parameter; *p < .05, **p < .01, ***p < .001.
  5. 4Survey item, "Do you consider yourself a physically active person?" Response options - yes or no.
  6. 5Survey item, "How satisfied are you with your current weight?" 5-point response scale ranging from 1 = very satisfied to 5 = very unsatisfied.
  7. 6EDI-3 entries are normed percentiles.
  8. 7Food like index = Preference score of foods liked (denoted by preference selection of 5 to 9) divided by number of foods like. Possible range 5 though 9; higher score denotes greater preference.
  9. 8Food dislike index = preference score of foods disliked divided by number of foods disliked. Possible range 1 through 4; higher score denotes greater dislike.
  10. 9Computed scores collapsed to two categories - pre-action (precontemplation, contemplation, and preparation) vs. action/maintenance.
  11. 10For locus of control, range: 5 = external locus of control, 15 = internal locus of control. For all other EFNEP items, range: 1 = does not do, 5 = almost always does.
  12. 11Compared to preparing food at home ≤ 3 times per week.
  13. 12Survey item, "How do you feel about cooking?" Response options - Likes cooking compared to Doesn't Like/Doesn't Mind Cooking.
