“…The effectiveness of the PPIs has been tested in many cultures beyond English-speaking populations. For example, there are PPIs studies in Norway (Drozd, Mork, Nielsen, Raeder, & Bjørkli, 2014), Switzerland (Gander, Proyer, Ruch, & Wyss, 2013), Turkey (Koydemir & Sun-Selisik, 2015), Israel (Gelfin, Zohar, & Lev-Ari, 2018) Iran (Dowlatabadi et al, 2016), Japan (Otake, Shimai, Tanaka-Matsumi, Otsui, & Fredrickson, 2006), China (Lü, Wang, & Liu, 2013), Korea (Im, 2016), Taiwan (Wu & Koo, 2016) or Suriname (Hendricks, 2017). To date there have been some initial research in Greece by Symeonidou, Moraitou, Pezirkianidis, & Stalikas (2018) and Dimitropoulou & Leontopoulou (2017).…”
