↵* The β coefficient from linear mixed model regression output × 100 results in the mean difference in the composite scores as a percentage of a 1-unit change in each predictor variable, adjusting for all other variables in the model. A positive value indicates that respondents answered yes to more questions as the value of the predictor increased.
