The resulting sample consisted of 123 participants of the 187 who volunteered
for the study. Site A had 89 usable survey packets returned out of the 138 potential
volunteers who returned a postcard indicating an interest in joining the study. Of
the 49 potential volunteers who did not call to opt out of the study, 34 returned
completed survey packets at site B. An equal distribution of men ( n = 59) and women
( n = 59) reported their gender.
