“…In the past 2 decades, many researchers have emphasized the importance of encouraging hospitalized children to participate in clinical decision making (Coyne, ; Coyne, Amorya, Kiernan, & Gibson, ; Moore & Kirk, ; Runeson, Enskar, Elander, & Hermeren, ), promoting children to express their own views in accordance with their age and maturity (Department of Health , ; Runeson et al., ); more recently, researchers have recognized the importance of also including children as research participants (Coyne, ). However, very few studies have investigated pediatric patient valuations (Mah, Tough, Fung, Douglas‐England, & Verhoef, ), and few studies have explored, as a primary outcome, the quality of pediatric nursing care from the children's points of view (Pelander, Leino‐Kilpi, & Katajisto, , ).
