Post information beliefs by group
| Construct | Question | Scale* | SI (n = 590) | SI + N (n = 631) | Result |
|---|---|---|---|---|---|
| Perceived vulnerability | If I never do the FOB screening test, I would feel very vulnerable to bowel cancer | 1-5 | 3.13 (.99) | 3.25 (1.06) | t(1208) = -2.00, p = .045 |
| Self-efficacy | I would be confident that I could do the FOB test correctly | 1-4 | 3.29 (.55) | 3.36 (.57) | t(1208) = -1.92, p = .055 |
| Response efficacy | Doing the FOB test would reduce my chances of dying from bowel cancer | 1-4 | 3.17 (.66) | 3.27 (.66) | t(1201) = -2.64, p = .008 |
| Peace of mind | Doing the FOB test would give me peace of mind | 1-4 | 3.22 (.61) | 3.33 (.61) | t(1199) = -3.15, p = .002 |
| Disgust | Doing the FOB test would be disgusting | 1-4 | 1.92 (.75) | 1.81 (.71) | t(1204) = 2.69, p = .007 |
| Symptom absence | I would only do the FOB test if I had symptoms of bowel cancer | 1-4 | 1.67 (.70) | 1.60 (.71) | t(1196) = 1.39, p = .165 |
*Higher scores = more agreement.
