“…There are multiple IPVA studies of young people that have used LCA, but these studies almost exclusively come from north America, whereby the social and educational context greatly differs, as do modes of violence (e.g. the prevalence of violence through gun crime), compared with in the UK (Brooks-Russell, Foshee, & Ennett, 2013;French, Bi, Latimore, Klemp, & Butler, 2014;Goncy, Sullivan, Farrell, Mehari, & Garthe, 2017;Haynie et al, 2013;Hebert, Moreau, Blais, Oussaid, & Lavoie, 2018;Lapierre, Paradis, Todorov, Blais, & Hebert, 2019;Martin-Storey & Fromme, 2016;Mumford, Liu, & Taylor, 2019;Sessarego, Siller, & Edwards, 2019;Swartout, Cook, & White, 2012;Weir & Kaukinen, 2019). In addition, the broad majority of these LCA studies address longitudinal patterns/trajectories of either IPVA victimisation or IPVA perpetration occurrence over time, but not co-occurrence of different victimisation or perpetration types.…”
