N = 3844. CR = case reporting; PaR = patient referral; PrR = provider referral. Percentage of variance refers to the proportion of variance accounted for by each factor (I–IV) for each variable (CR, PaR, PRR). Reliability refers to coefficient α (internal consistency) for each of the bold items defining the four factors (I–IV) across the three variables (CR, PaR, PRR).
