“…In some studies, sibling behavior problems were in the clinical range (2 SDs above the mean) on a standardized instrument (Laufersweiler-Plass et al, 2003;Lobato, Barbour, Hall & Miller, 1987). For these siblings and families, crisis intervention strategies and health services have been described (Dattilio & Freeman, 2000;Fanos, Fahner, Jelveh, King & Taeda, 2005). It is noted also that a recent study by Williams et al (2009) found that parents' descriptions reflected mainly negative effects (74.7%) in siblings of children with cystic fibrosis and cancer, with 24.2% reflecting some positive effects and only 1.1% of parents reporting "no effects."…”
