Aim Sexual violence is global public health, human rights and gender equality issue. Sexual violence bystander programmes for nightlife workers are emerging across a few countries and further examination of such programmes is required. This exploratory study evaluates the potential effectiveness of the Good Night Out Campaign, a sexual violence bystander programme for nightlife workers.

Methods 207 trainees attending the 1.5 hour training programme across two cities in England were recruited opportunistically, immediately prior to training delivery. Sexual violence myth acceptance and readiness and confidence to intervene in sexual violence were measured at baseline and post-intervention. Analyses used paired-sample tests to examine differences in the three measurements pre to post-training and effect sizes were quantified using Cohen’s d.

Results Compared to pre-training, post-training participants were significantly (p<0.001) less likely to agree with sexual violence myths, and more likely to be confident and ready to intervene in sexual violence or incidents of vulnerability. Effect sizes were small-medium.

Conclusions The study adds to emergent evidence suggesting that sexual violence bystander programmes may be promising in decreasing sexual violence myths and barriers to bystander intervention, and increasing willingness to intervene amongst nightlife workers. Findings can support the emergence of sexual violence prevention activities implemented in nightlife spaces. Further programme implementation and evaluation using experimental designs is needed to explore outcomes in greater depth, considering the complexity of the nightlife environment.
