“…Ambivalence often derives from behaviours that are problems but that also hold an intrinsic reward value; bullying is likely to be such a behaviour, in light of the social and/or instrumental rewards that can accrue from bullying others (see Cross et al, 2018 for a full conceptual mapping of the rationale for use of MI with bullying). MI has been effective for behaviours such as medication compliance, HIV risk, and obesity (Lenz, Rosenbaum, & Sheperis, 2016;Lundahl, Tollefson, Kunz, Brownell, & Burke, 2010). It has shown its value with adolescents (Erickson, Gerstle & Feldstein, 2005), in schools for issues such as academic disengagement (Frey et al, 2011;Rollnick, Kaplan, & Rutschman, 2016;Snape & Atkinson, 2016, and in reducing alcohol-related violence in youth (Cunningham et al, 2012).…”
