Mixed-Effects Multivariable Linear Regression Model Analyzing the Relationship Between Shared Decision-Making Score and Physician Trust
| Variable | Regression Coefficienta | 95% CI | P Value |
|---|---|---|---|
| Shared decision-making (SDM) score | 0.37 | 0.08 to 0.67 | .013 |
| Surrogate age | –0.01 | –0.03 to 0.16 | .581 |
| Surrogate health literacy score | 0.08 | 0.03 to 0.13 | .003 |
| Closeness of relationship to patient: spouse/child/parent (Ref: other relationship) | –0.78 | –1.47 to –0.08 | .029 |
| Physician male (Ref: female) | 0.80 | 0.02 to 1.59 | .046 |
| Preconference trust score | –0.41 | –0.50 to –0.33 | < .001 |

Regression coefficient interpretation: For every additional element of SDM used by the physician, surrogate trust in the treating physician increased by 0.37 point.
