Qualification level, experience, and gender as predictors of factor scores1
| Characteristic | Factor score—comparison | Factor score—reference | OR (95% CI) | p |
|---|---|---|---|---|
| Factor 1: Judging MOIs (do the presented MOIs have the potential to cause a spine injury?) | ||||
| ALS (ref BLS) | 6 (4–7) | 5 (3.5–7) | 0.79 (0.40—1.54) | 0.5 |
| > 10 years exp. (ref < = 10 years) | 6 (4–9) | 5 (3–7) | 1.72 (0.87—3.39) | 0.1 |
| Men (ref Women) | 5 (3–7) | 6 (4–7) | 0.74 (0.41—1.34) | 0.3 |
| Scoring range, direction: 0 (fewer with potential)—9 (more with potential) | ||||
| OR > 1 means more likely to judge MOIs as potentially causing injury | ||||
| Likelihood ratio test (full model compared to intercept-only), x2(3) = 3.52, p = 0.3 | ||||
| Factor 2: Treatment Value (composite view of the value of SMR) | ||||
| ALS (ref BLS) | 26.5 (24–29) | 25 (22–27) | 2.40 (1.21—4.76) | 0.01 |
| > 10 years exp. (ref < = 10 years) | 26 (23–37) | 25 (22–28) | 1.25 (0.64—2.45) | 0.5 |
| Men (ref Women) | 25 (22–28) | 26 (24–29.75) | 0.53 (0.28—0.99) | 0.05 |
| Scoring range and direction: 8 (less skeptical)—40 (more skeptical) | ||||
| OR > 1 means more likely to have a higher score | ||||
| Likelihood ratio test (full model compared to intercept-only), x2(3) = 15.84, p = 0.001 | ||||
