Evaluating the mentors in violence prevention programme: a theoretical, longitudinal, and implementation approach

Student thesis: Doctoral Thesis


This thesis provided the most detailed examination to date of the Mentors in Violence Prevention (MVP; Katz, 1995) programme in targeting gender-based violence. Three studies were undertaken: Study 1 tested an augmented Prototype Willingness Model (Gibbons & Gerrard, 1995, 1997) to identify factors (attitudes, beliefs, motivations, and behaviours) most strongly associated with bystander decision-making; Study 2 was a longitudinal examination of changes in these factors after exposure to the MVP programme; and Study 3 examined the impacts of implementation factors (fidelity, dosage, and adaptation; Damschroder et al., 2009) on changes in these factors. The research involved 2079 participants (50% males, 49% females), aged 11-15-years-old (M = 12.32, SD = 0.91), attending 19 Scottish secondary schools, with four time points which enabled the examination of the aims of the three studies. Study 3 also used a sample of 118 MVP mentors (18% males, 82% females), aged 15-18 years old (M = 16.42, SD = 0.60). Results from Study 1 highlighted that self-comparison to the typical bystander who positively intervenes, confidence in one’s own abilities to intervene, and positive attitudes towards intervening, were the strongest predictors of intentions and willingness to intervene, with self-efficacy and willingness being the strongest predictors of intervention behaviour. However, Study 2 found no significant MVP effects on changes in these decision-making factors. Furthermore, Study 3 found no significant implementation effects on these changes. These findings make a unique contribution to theory by providing evidence that bystanders deciding to intervene can both react to gender-based violence without much thought and also deliberate over it more thoughtfully. Findings also provide novel insight into the effectiveness of MVP by highlighting the need for more of a focus on gender-based violence as well as highlighting the need for key bystander decision-making factors to be addressed during the delivery of MVP.
