Area of Science:

  • Public Health
  • Biostatistics
  • Sexual Health Research

Background:

  • Analyzing condom use frequency often involves nonnormally distributed data.
  • Dichotomizing these measures can lead to problematic transformations for researchers.
  • A need exists for robust analytical approaches in sexual behavior research.

Purpose of the Study:

  • To demonstrate the utility of a screening analysis prior to dichotomizing condom use frequency data.
  • To compare different condom use patterns using a comprehensive set of measures.
  • To highlight best practices in statistical analysis for sexual health surveys.

Main Methods:

  • Utilized data from an anonymous, cross-sectional survey of 483 university undergraduates.
  • Conducted a screening analysis on 14 different measures related to condom use.

  • Compared inconsistent condom users to consistent users and never-users.

    • Main Results:

    • The screening analysis revealed significant differences between user groups across various measures.
    • Pre-dichotomization analysis provided nuanced insights into condom use patterns.
    • Statistical comparisons highlighted the importance of examining distributions before simplification.

    Conclusions:

    • A pre-dichotomization screening analysis is a valuable tool for researchers studying condom use frequency.
    • This approach enhances the understanding of nonnormally distributed sexual behavior data.
    • Adopting screening analyses can improve the rigor of statistical findings in public health research.
