^aOnly participants who had advertisement attitudes data were included
^bMissing data in this variable were mean replaced; the results of an analysis with or without mean replacement did not differ
^cbecause of the large amount of missing data and the nature of the question (i.e., participants may not have answered if they didn’t try new activities) the analyses were conducted without replacing the missing data
