238 I.H. Zaal-Schuller et al. / Research in Developmental Disabilities 49–50 (2016) 235–246 3. Results The literature search identified 2933 discrete citations. After screening the corresponding titles and abstracts, 35 studies seemed to be eligible for inclusion according to our criteria. The full texts of these studies were then reviewed in-depth. Thirty studies had to be excluded: 6 studies that included no, or too few, children with SDDs; 13 studies that did not focus on EoLDM; 5 studies that did not focus on the parents’ perspective; and 6 studies that appeared to be case reports. An additional 4 studies were subsequently found by searching the reference lists of suitable studies. In the end, nine studies were eligible for inclusion in our review. The flow of information for our review is summarized in Fig. 1. In Table 1, we present the characteristics of the 9 included studies. The studies were inconsistent in the terminology used to describe EoLDs. We encountered, for example, ‘limit or withdraw life support’ (Sharman, Meert, & Sarnaik, 2005), ‘decision-making in the PICU’ (Madrigal et al., 2012), ‘choosing plan of care’ (Guon, Wilfond, Farlow, Brazg, & Janvier, 2014) and ‘critical decisions’ (October, Fisher, Feudtner, & Hinds, 2014). All but two studies had a qualitative design, although in some studies questionnaires were used (Guon et al., 2014; October et al., 2014). The remaining two studies had a quantitative design (Friedman, 2006; Madrigal et al., 2012). Three of the nine studies prospectively followed parents throughout the decision-making process (Madrigal et al., 2012; October et al., 2014; Sharman et al., 2005). The other six studies retrospectively investigated parents’ experiences and preferences. In these studies, the period of time that had elapsed between the EoL decision and study participation varied considerably, from several months up to nineteen years (Brotherton & Abbott, 2012; Friedman, 2006; Guon et al., 2014; Morrow, Quine, Loughlin, & Craig, 2008; Rapoport, Shaheed, Newman, Rugg, & Steele, 2013; Reilly, Huws, Hastings, & Vaughan, 2010). All studies were conducted in the United Kingdom, United States, Australia or Canada. In Table 2, we present regulations of parental involvement and conflict resolution in these countries according to the professional guidelines. One study also included a small percentage of parents from other countries (Guon et al., 2014).
