abstract="Working with men to prevent their perpetration of intimate partner violence and  non-partner sexual violence is increasingly recognised as effective. However, in any  given context there are a multiplicity of masculinities, each of which has a  different association with violence perpetration. There remains lack of clarity  about whether such interventions impact all men and masculinities equally. We  undertook a post-hoc analysis of men involved in the successful Stepping Stones and  Creating Futures cluster randomized control trial in Durban, South Africa, to  assess: i) whether there were different groups of men, ii) the factors associated  with group allocation, and iii) whether the intervention had a differential impact  on these groups in terms of violence perpetration. We used Latent Class Analysis  (LCA) to identify masculinity classes, based on fit statistics and theoretical  plausibility, and then used descriptive statistics (numbers, percentages, means) and  p-values and multinomial models (95% confidence intervals, p-values) to assess  factors associated with allocation to each class. To assess intervention impact by  group, we used an intention-to-treat analysis, comparing men in each masculinity  class, by intervention and control arm, using generalized estimating equations  reporting unadjusted and adjusted odds ratios (aORs). In total 674 were recruited at  baseline, and the LCA identified three classes of men: high violence (29% of men),  medium violence (50% of men) and low violence (21% of men). Multinomial models  showed those in more violent classes were more supportive of violence, had more  adverse experiences, more depression and had worked more. By masculinity class, the  impact of SS-CF showed reductions among the most violent men, with significant  reductions in past year physical IPV (aOR0.59, p = 0.014), emotional IPV (aOR0.44,  p = 0.044) and economic IPV (aOR0.35, p = 0.004), with non-significant reductions  among other classes of men. This analysis suggests intensive group-based  interventions can have significant impacts on the most violent men in communities.<p /> <p>Language: en</p>",
