¹⁾Knowledge scores were computed by summing the number of correct responses (correct response = 1, incorrect response = 0), with a possible range of 0–6
²⁾Belief scores were computed by summing the number of yes response for presence of belief (yes response = 1, no response = 0), with a possible range of 0–3
