Abstract
The Psychometric Evaluation of Sexual Violence Prevention
Instruments for Use with Male
College Students
By: James Walker
The purpose of this study was to assess the psychometric properties
of three novel scales and two
novel indexes developed and used in the RealConsent study, a
web-based sexual violence
preventive intervention for male undergraduates implemented and
evaluated at Georgia State
University. These metrics assessed five important constructs
designed for use in evaluations of
sexual violence interventions: legal knowledge of informed consent,
perceptions of informed
consent, self-efficacy to intervene when a woman's consent is
compromised, outcome
expectancies for non-consensual sex, and outcome expectancies for
intervening behaviors. Each
scale was assessed for reliability and validity. Results showed
that one of the three novel scales:
Self-Efficacy to Intervene, and one of the two indexes: Perceptions
of Informed Consent for Sex,
showed adequate reliability and validity. These two metrics are
therefore verified for future
research efforts, while the other three may need further analysis
or modification to enhance their
utility in future studies.
