Research on pornography use and sexual coercion has provided inconsistent results. One explanation for this is the lack of a valid, reliable, and comprehensive measure of pornography use. This study seeks to address this need by developing a comprehensive pornography use instrument consisting of four domains identified in research: type of pornogra...

Decades of research have examined the association between pornography use and sexual coercion, with the most significant relationships found between more deviant genres of pornography use and sexual violence. However, researchers have yet to provide a comparable body of research examining the theoretical mechanism of this association. One theory th...

The ability to identify factors predictive of recidivism among individuals who have offended is integral to properly targeting supervision and treatment focus. Instruments such as the Level of Service Inventory-Revised (LSI-R) show promise with general justice-involved females, but no study to our knowledge has assessed it with women who have sexua...

Although many instruments have been validated to assess risk of sexual recidivism among men, no similar tool exists for women who have sexually offended. As a result, some jurisdictions use male-based instruments to assess women despite the lack of validation research examining the predictive utility for this subgroup. This study examined the utili...

The increased accessibility and use of pornography in Western society highlights the emergent need to understand the relationship between its use and sexual coercion. Decades of research have demonstrated a consistent relationship between pornography use and engaging in sexually aggressive behavior, although what drives this relationship remains la...

Research indicates that pornography use is now practically ubiquitous among males and continually increasing among females. These statistics are concerning in light of decades of research signaling that pornography use may be associated with sexually coercive behavior. Though the relationship between pornography use and sexual coercion has been a f...

As criminal justice professionals are asked to assign risk levels and treat females who sexually offend, identifying risk factors for recidivism prediction and treatment targets is important. Although the majority of risk and treatment studies have focused on males, general female offender research and developing research with female sex offenders...

Research on justice-involved women has provided evidence for the importance of using gender-specific information in the assessment, treatment, and understanding of criminal pathways and risk of recidivism in women who have committed offenses. Although research on women who have sexually offended suggests there are differences between men and women...

Research has consistently shown a relationship between pornography use and sexually coercive behaviors, but this inquiry has yet to fully examine the theoretical mechanisms through which this relationship works. The current study will use a theory that has gained support and attention as a way to understand the relationship pornography use has with...

Due to the smaller proportion of female sex offenders (2%-12% of all sexual offenses) compared with male sex offenders, we know much less about these women to aid in the assessment, treatment, and prevention of their offending behavior compared with men. One promising distinction in female sex offender typology is solo-offending females versus fema...

According to recent statistics, as many as one in five female college students are victims of sexual assault during their college career. To combat what has been called the “Campus Rape Crisis,” researchers have attempted to understand what variables are associated with sexually coercive behaviors in college males. Although investigators have found...
