AIP Autonomy and Independent Practice, NP-AR NP-Administration Relations. Models including Level-1 covariates as random effects are not in the table. This information is available upon request. Final model, or Model 2, controlled for the effects of sex, education, and high workload, which were significant at p values < 0.20 in bivariate testing. *p < 0.001; †p < 0.0001
