To measure personal involvement, survey respondents answered the following
question on a 10-point scale:
How important personally is breast cancer research to you, on a scale of 1 (not at all
important) to 10 (extremely important)?

The results, shown in Table 4, indicated that the data were right-skewed and that the
median score was 8. Therefore, a dichotomous variable was created where 0 = low
involvement (0-8) and 1 = high involvement (9-10). Frequencies of the new
dichotomous variable for personal involvement (persinv) are presented in the results
section. The mean for the dichotomous personal involvement variable was .4485 and
the standard deviation .4983.
