“…In total, 20 studies focused on physical natural abilities, including 18 studies based on a cross-sectional design and 2 studies on a (multi-cohort) longitudinal design. The methodological quality evaluation for validity yielded good (n = 1) (Panjan et al, 2010), fair (n = 10) (Faber, Oosterveld, & Nijhuis-Van Der Sanden, 2014;Filipčič & Filipčič, 2005a, 2005bFilipčič, Pisk, & Filipčič, 2010;Filipčič & Završki, 2002;Leone & Larivière, 1998;Mantis et al, 1998;Nikolić, Furjan-Mandić, & Kondrič, 2014;Roetert, Brown, Piorkowskil, & Woods, 1996;Roetert et al, 1992), to poor (n = 9) (Amusa, Toriola, & Dhaliwal, 2002;Bencke et al, 2002;Elliott, Ackland, Blanksby, & Bloomfield, 1990;Girard & Millet, 2009;Karnia et al, 2010;Landlinger, Stöggl, Lindinger, Wagner, & Müller, 2012;Roetert, Piorkowski, Woods, & Brown, 1995;Van Den Berg, Coetzee, & Pienaar, 2006;Ziemann, Sledziewska, Grywacz, Gibson, & Wierzba, 2011) ratings. Most instruments found for measuring physical natural abilities were rated from negative based on moderate evidence (-) to conflicting findings (+/-).…”
