Transformation of nonnormally distributed measures of
condom use
frequency can be problematic for researchers. Distributions are
typically dichotomized. We used data collected from 483 university
undergraduates in an anonymous, cross-sectional survey to illustrate
the value of a screening analysis before dichotomization. Inconsistent
condom users were compared to consistent users with respect to 14
measures. Subsequently, inconsistent users were compared to those who
never used condoms with regard to the same 14 measures. Findings
suggest that a screening analysis is a potentially important aspect of
analyzing distributions that assess frequency of condom use.
