Abstract
Objectives
Examine the effect of a 40-h police sexual assault training and individual-level impulsivity on officers’ intention to make an arrest and the importance placed on using procedural justice when interacting with victims.
Methods
Training courses were randomly assigned to the treatment and control groups. Vignettes depicting sexual assault reports were randomly assigned to participants (N=318) in each group. Vignette manipulations were randomized by victim-offender relationship (stranger/non-stranger) and rape myth acceptance (present/not present/ambiguous).
Results
Training increased officers’ intentions to arrest. Training and lower impulsivity increased the importance officers placed on using procedural justice. Vignette manipulations were not significantly correlated with either outcome. Impulsivity did not moderate—or change—training effects.
Conclusions
Sexual assault training can increase officers’ self-reported intentions to arrest and the perceived importance placed on using procedural justice in interactions with victims. This finding is important as prior research demonstrated that using procedural justice principles can improve victim engagement with investigators.

Notes
Specifically, the SAFE Act required that agencies with fewer than 5 officers send at least 1 representative to the training, agencies with 5 to 30 officers send at least 2 officers, and agencies with more than 30 officers send at least 4 officers.
Because the arrest variable was ordinal, an ordinal logistic regression model was also estimated. The results mirrored findings from the OLS regression results. Specifically, training (b = .88, p = .00) significantly increased the likelihood of arrest, while impulsivity (b = −.21, p = .12), stranger case (b = .27, p = .28), and rape myths case (b = .33, p = .20) were not significantly related to arrest.
The interaction term Training×Impulsivity was included because of the significant relationship between impulsivity and procedural justice in the direct effects model. Because the measures of stranger case and rape myths case were not correlated with either outcome, interactions between these variables and training were not included in the analyses.
