Bystander intervention among secondary school pupils: Testing an augmented Prototype Willingness Model

Evaluating Mentors in Violence Prevention: A Longitudinal, Multilevel Assessment of Outcome Changes

There is a need to increase understanding of the effectiveness of bystander programmes targeting gender-based violence in the United Kingdom. There is also a need to utilise a robust theoretical models of decision-making while doing so. Changes were examined in bystanders' attitudes, beliefs, motivations towards intervening, and intervention behavior in situations of gender-based violence. To achieve this, a quantitative examination of Mentors in Violence Prevention was conducted. There were 1396 participants (50% female, 50% male) who were aged 11 to 14 years old (M = 12.25, SD = 0.84) attending high school at the first time point. Participants were attending 17 schools (53% Mentors in Violence Prevention and 47% control) in Scotland. Outcome variables were assessed approximately one year apart using questionnaires. Multilevel linear regressions revealed that Mentors in Violence Prevention did not change outcomes reflecting bystanders' attitudes, beliefs, motivations towards intervening, or intervention behavior in gender-based violence. Discrepancies between the current findings and those of other evaluations may be due to other studies including small numbers of schools that may be more motivated to implement the program. This study also identified two key issues that need to be addressed at stakeholder level before concluding that Mentors in Violence Prevention is ineffective at targeting gender-based violence. That the program has moved towards a more gender-neutral approach in the United Kingdom could explain the null results of this study. Furthermore, the current findings could be attributed to a failure to adequately address the theoretical model underpinning the program in practice.

Evaluating the Mentors in Violence Prevention Program: A Process Examination of How Implementation Can Affect Gender-Based Violence Outcomes

Gender-based violence is a global public health issue and major human rights concern. It is also a type of violence that is disproportionately experienced by women and girls. This study is the first to examine multiple implementation process (dosage, fidelity, and adaptation) effects on changes in anticipated outcomes of a school-based bystander program targeting gender-based violence, Mentors in Violence Prevention (MVP). Data were collected from two participant groups: mentees (students receiving MVP) and mentors (students delivering MVP), across nine participating high schools. The mentee sample comprised 698 students (about 48.9% males and 49.7% females), aged 11 to 14 years old (M = 11.86, SD = 0.64). The mentor sample comprised 118 students (17.80% males, 82.20% females), aged 15 to 18 years old (M = 16.42, SD = 0.60). Anticipated outcomes were changes in bystanders' attitudes, social influences, control perceptions, intentions, willingness, and intervention behavior, measured using mentees' self-reports at two time points approximately 1 year apart. Implementation processes were measured using mentors' self-reports. Analyses revealed no effects for any of the implementation variables across changes in any of the outcomes measured. These results highlight important implications for the implementation of the MVP program going forward, given its widespread implementation in the United Kingdom. Possible ways that MVP may be enhanced in future are discussed. For example, furthering understanding into how gender-based violence and bystander intervention are addressed and framed during MVP lessons would give more insight into how the current implementation of the program can be improved to maximize its potential benefits.
