“…Interestingly, mindfulness is negatively related to GD severity ( Lakey, Campbell, Brown, & Goodie, 2007 ; Reid, Di Tirro, & Fong, 2014 ; Riley, 2012 ), suggesting that PGs may have a deficit in the ability to accept emotional states in a non-judgmental way. In addition, studies on metacognition capacities among PGs provided preliminary evidence that GD severity may be related to positive beliefs toward the need to control thoughts ( Jauregui, Urbiola, & Estevez, 2016 ; Lindberg, Fernie, & Spada, 2011 ; Mansueto et al., 2016 ; Spada & Roarty, 2015 ). PGs often believe that certain types of thoughts have to be suppressed, and this has been demonstrated by Riley ( 2012 ), which reported high levels of thought suppression among PGs.…”
