“…Research on chronic pediatric pain abounds in the evaluation of etiology, pathophysiological factors, diagnostic processes, pharmacological, and physical treatments (Blackman, Svensson, & Marchand, 2018; Gmuca et al, 2018; Orava, Provvidenza, Townley, & Kingsnorth, 2018; Pas et al, 2018; Riquelme, do Rosário, Vehmaskoski, Natunen, & Montoya, 2018; Sheehy et al, 2015); on the contrary, although some lines of research exist (Cáceres-Matos, Gil-García, Barrientos-Trigo, Molina, & Porcel-Gálvez, 2019; Vega et al, 2018; Yetwin, Mahrer, John, & Gold, 2018), current data are more lacking in the evaluation of non-physical variables associated with chronic pediatric pain and related potentially complementary interventions.…”
