“…Although the inclusion criteria allowed for a broader range of study designs, only experimental trials met the additional inclusion criteria (i.e., studies assessing parent engagement). The included studies can be categorised into two not-mutually-exclusive groups: (1) studies measuring predictors of engagement ( n = 17; Baker, Arnold & Meagher, 2011 ; Brody et al, 2006 ; Byrnes et al, 2012 ; Calam et al, 2008 ; Carpentier et al, 2007 ; Eisner & Meidert, 2011 ; Fleming et al, 2015 ; Garvey et al, 2006 ; Heinrichs et al, 2005 ; Hellenthal, 2009 ; Mauricio et al, 2014 ; Mian, Eisenhower & Carter, 2015 ; Nordstrom, Dumas & Gitter, 2008 ; Plueck et al, 2010 ; Reedtz et al, 2011 ; Skärstrand et al, 2009 ; Winslow et al, 2009 ), and (2) studies that evaluated engagement methodologies ( n = 9; Aalborg et al, 2012 ; Bjørknes, Jakobsen & Nærde, 2011 ; Byrnes et al, 2012 ; Calam et al, 2008 ; Carpentier et al, 2007 ; Eisner & Meidert, 2011 ; Heinrichs, 2006 ; Helfenbaum-Kun & Ortiz, 2007 ; Mian, Eisenhower & Carter, 2015 ). Some studies had dual aims (i.e., evaluation of an engagement methodology and measurement of predictors; Calam et al, 2008 ; Carpentier et al, 2007 ; Eisner & Meidert, 2011 ; Mian, Eisenhower & Carter, 2015 ).…”
