“…Furthermore, studies have demonstrated that functional assessment methodology is relevant for diverse ages, ranging from preschool (e.g., Duda, Dunlap, Fox, Lentini, & Clarke, 2004) through adolescence (e.g., Radford & Ervin, 2002; Turton, Umbreit, Liaupsin, & Bartley, 2007). In addition, cross-cultural applications suggest that functional assessment is an adaptable process responsive to differing values and social practices (Baba & Tanaka-Matsumi, 2011; Cho Blair, Umbreit, Dunlap, & Jung, 2007; Moreno & Gaytán, 2013; Theodoridou & Koutsoklenis, 2013; Turton et al, 2007). Finally, researchers have directly compared the effects of intervention that is function-derived with nonfunction-derived intervention, demonstrating the superiority of interventions linked to behavioral function (Ingram, Lewis-Palmer, & Sugai, 2005; Newcomer & Lewis, 2004; Payne, Scott, & Conroy, 2007).…”
