Purpose
Preventing
sexual aggression (SA) can be informed by determining if time-varying risk
factors differentiate men who follow different sexual aggression risk
trajectories.
Methods
Data
are from a longitudinal study with 795 college males surveyed at the end of
each of their 4 years of college in 2008–2011. Repeated measures general linear
models tested if changes in risk factors corresponded with sexual aggression
trajectory membership.
Results
Changes
in the risk factors corresponded with SA trajectories. Men who came to college
with a history of SA but decreased their perpetration likelihood during college
showed concurrent decreases in sexual compulsivity, impulsivity, hostile attitudes
toward women, rape supportive beliefs, perceptions of peer approval of forced
sex, and perceptions of peer pressure to have sex with many different women,
and smaller increases in pornography use over their college years. Conversely,
men who increased levels of SA over time demonstrated larger increases in risk
factors in comparison to other trajectory groups.
Conclusions
The
odds that males engaged in sexual aggression corresponded with changes in key
risk factors. Risk factors were not static and interventions designed to alter
them may lead to changes in sexual aggression risk.
