“…Most studies focus on PE in the United States (e.g., Simons-Morton et al, 1994 ; McKenzie et al, 1995 , 2000 , 2004 ; Nader, 2003 ; Scruggs et al, 2003 ; Surapiboonchai et al, 2012 ; Robinson et al, 2014 ; Harvey et al, 2016 ). Besides, there are studies in some European (e.g., Verstraete et al, 2007 ; Waring et al, 2007 ; Carreiro da Costa et al, 2008 ; Meyer et al, 2013 ; Fröberg et al, 2017 ) and a few Asian countries (e.g., Chow et al, 2008 ; Tanaka et al, 2018 ; Zimmo et al, 2020 ). Compatible analyses of German PE, however, have nearly not been introduced to international research yet (see Kobel et al, 2015 for an exception).…”
