^*P-values are calculated using McNemar’s test for paired binary data using the discordant pairs for each question (data not shown). For the purpose of this analysis, strongly agree is combined with agree; undecided, disagree and strongly disagree are combined. Similarly, always, often and sometimes are combined; rarely and never are combined.
