Table 3 Logistic regression model results for testing-specific analysis (Stage 5 to 6)
Construct | Question | Full Model Odds Ratio (95% Confidence Interval) N = 1417 | Refined Model Odds Ratio (95% Confidence Interval) N = 1449 |
|---|---|---|---|
Demographic/ lifestyle | Age of youngest person in home (older than 18 vs. 18 and under) | 1.88 (1.47—2.39)*** | 1.85 (1.45 – 2.34)*** |
Smoking status (rest vs. any known current smoker) | 1.65 (1.11—2.45)* | 1.66 (1.11 – 2.45)* | |
Perceived susceptibility | Radon is a problem in my area/neighbourhood. (agree vs. disagree/neutral) | 1.50 (0.85—2.80) | |
My home likely has enough radon that I should do something about it. (agree vs. disagree/neutral) | 1.66 (0.98—2.94) | ||
If radon is in my home, it is likely that someone in my household will get sick from it. (agree vs. disagree/neutral) | 1.32 (0.78—1.67) | ||
Perceived severity | If someone in my household got sick from radon, it would be very serious. (agree vs. disagree/neutral) | 1.14 (0.74—2.29) | |
Perceived benefits | If I reduced the levels of radon in my home, it would reduce the chances of someone getting sick from it. (agree vs. disagree/neutral) | 1.57 (1.08—2.29)* | 1.91 (1.39 – 2.62)*** |
Perceived barriers/self-efficacy | If I had high levels of radon in my home, I wouldn’t have the time to fix it. (agree/neutral vs. disagree) | 0.78 (0.58—1.05) | |
If I had high levels of radon in my home, it would be too expensive to fix. (agree vs. disagree/neutral) | 0.72 (0.52—1.00)* | 0.64 (0.47 – 0.87)** | |
Even if a radon problem was fixed, my home would still be worth a lot less. (agree/neutral vs. disagree) | 0.82 (0.64—1.05) |
