“…Most of the studies measured all these factors by means of a few items: for example, 1 item (de Heer et al, 2020; Dong et al, 2013; Hagen et al, 2018; Kohut et al, 2020; Malamuth et al, 2012; Spadine et al, 2020; Wright & Tokunaga, 2016), 2 items (Huntington et al, 2021; Leemis et al, 2019; Simons et al, 2012; Stanley et al, 2018), 3 items (Brown & L’Engle, 2009; Huntington et al, 2022), 4 items (Kernsmith & Kernsmith, 2009; Tomaszewska & Krahé, 2018), 5 items (Carr & VanDeusen, 2004), 6 items (Franklin, 2013; Goodson et al, 2020), 7 items (Chang et al, 2016; Mikorski & Szymanski, 2017), or 8 items (D’Abreu & Krahé, 2014; D’Abreu & Krahé, 2016; Lam & Chan, 2007), with one outlier assessing 46 items (Gonsalves et al, 2015). Seven studies used validated instruments to assess the use of pornography or violent pornography (Hald & Malamuth, 2015; Hughes et al, 2020; Huntington et al, 2022; Mikorski & Szymanski, 2017; Palermo et al, 2019; Rostad et al, 2019; Shin & Lee, 2019).…”
