“…Direct support persons can, in general, accept and adopt the principles of physical activation of people with intellectual disability, but to what extent they think these are also applicable to persons with PIMD and implement them is unknown. Research on people with intellectual disability in general shows that the attitudes of direct support persons are associated with levels of physical activity (Martin, McKenzie, Newman, Bowden, & Morris, 2011). The results of this study might be explained by the fact that direct support persons believe that people with such profound intellectual and motor disabilities cannot move, or alternatively, cannot profit from movement-oriented activities, although several studies prove otherwise (Houwen et al, 2014; Jones et al, 2007; Ogg-Groenendaal, Hermans, & Claessens, 2014;van der Putten et al, 2005).…”
