“…The WBFPS is a feasible, quick, and simple tool used to assess pain in children ages 3 years and older (Wong, Hockenberry-Eaton, Wilson, Winkelstein, & Schwartz, 2001), and it has been used in over 80 studies in different countries and has been translated to 10 languages to assess pain-related interventions (e.g., Badr (Zahr), Puzantian, Abboud, Abdallah, and Shahine, 2006; Kennedy, Shaikh, Fardy, Evans, & Crean, 2004;Massimi et al, 2011;Tomlinson, von Baeyer, Stinson, & Sung, 2010). The WBFPS includes 6 cartoon faces that range from a smiley expression (0-'no pain') to a crying face (10-'severe pain') ( Figure 3).…”
