  1. *p < .05, **p < .01, ***p < .001. Main analysis models adjust for demographics (coefficients not shown). Sensitivity analysis 1 models exclude demographics. Sensitivity analysis 2 models adjust for TPB variables, and exclude demographics. † Sample sizes differ across analyses due to missing data on demographic variables.
