“…With the large number of children undergoing surgery each year, decreased lengths of hospital stay and the shortage of bedside nurses, parental participation in their children's postoperative care, such as assessing and managing pain, is expected (DeMaso & Bujoreanu, 2013;Lim, Mackey, Liam, & He, 2012;Ruiz, Rivers, & Pop, 2012). However, several qualitative studies (Lim et al, 2012;Longard, Twycross, Williams, Hong, & Chorney, 2016; P€ olkki, Pietil€ a, Vehvil€ ainen-Julkunen, Laukkala, & Ryhanen, 2002;Tait, Voepel-Lewis, Snyder, & Malviya, 2008;Valizadeh, Ahmadi, & Zarea, 2016) and a quantitative survey (Healy, 2013) from various countries widely reported that parents had inadequate information and knowledge regarding pain relief strategies for their children's postoperative pains. Parents' misconceptions on the tolerance, side effects and addiction of analgesics (Finley, Kristjansdottir, & Forgeron, 2009;Lim et al, 2012;Rony, Fortier, Chorney, Perret, & Kain, 2010) can lead to inadequate uses of pain medication for their children (Voepel-Lewis, Zikmund-Fisher, Smith, Zyzanski, & Tait, 2015), especially when conflicting symptoms like high pain and an adverse effect are present (Longard et al, 2016;Voepel-Lewis et al, 2015).…”
