| Self-Efficacy Item | Intervention (n = 64) | Control (n = 64) | Intervention Effect Adjusted Mean Difference† (SE), p-value | |

| 4. How easy or hard would it be for you to work more fruits and vegetables than you normally into snacks for yourself and your family? | Baseline, mean (SD) | 7.04 (3.05) | 7.09 (2.71) | 1.23 (0.53) |
| Adjusted Change†, mean (SE) | 1.10 (0.38) | −0.13 (0.38) | p = 0.02* | |
| 5. How easy or hard would it be for you to cook vegetables in a way that is appealing to your family? | Baseline, mean (SD) | 7.27 (2.98) | 7.67 (2.48) | 0.94 (0.42) |
| Adjusted Change†, mean (SE) | 0.89 (0.30) | −0.06 (0.30) | p = 0.03* | |
| 6. How easy or hard would it be for you to make-up a vegetables dish with what you have on hand? | Baseline, mean (SD) | 7.55 (2.74) | 6.99 (2.77) | 0.90 (0.45) |
| Adjusted Change†, mean (SE) | 0.80 (0.32) | −0.10 (0.33) | p = 0.048* | |
| 7. How easy or hard would it be for you to try vegetables that you have not eaten before? | Baseline, mean (SD) | 5.75 (3.32) | 5.88 (3.14) | 0.01 (0.53) |
| Adjusted Change†, mean (SE) | 0.51 (0.37) | 0.50 (0.38) | P = 0.99 | |
| 8. How easy or hard would it be for you to prepare and cook new recipes? | Baseline, mean (SD) | 7.24 (3.03) | 6.70 (2.97) | 0.39 (0.47) |
| Adjusted Change†, mean (SE) | 0.86 (0.33) | 0.46 (0.34) | p = 0.40 | |
| Self-efficacy Sum | Baseline, mean (SD) | 55.03 (16.5) | 55.17 (14.2) | 4.09 (2.45) |
| Adjusted Change†, mean (SE) | 6.40 (1.76) | 2.30 (1.73) | p = 0.10 |
† Adjusted analyses control for site, baseline self-efficacy and education; *Statistically significant (p < 0.05)
For self-efficacy sum N = 148 (intervention = 64 and control = 64); For intervention group: n = 73 for item 1, n = 74 for items 2, 6 and 8, n = 70 for items 3 and 4, n = 71 for items 5 and 7; For control group: n = 68 for items 1, 3, 4 and 5, n = 67 for items 2, 5, 7 and 8
