“…Furthermore, type D personality (TDP) is also thought to be a risk for the development (Pedersen et al, 2006;Spindler et al, 2009;Yu et al, 2010;De Fazio et al, 2012), persistence (Martens et al, 2008;Smith et al, 2008;Doyle et al, 2011a, b;Romppel et al, 2012a) and worsening (Romppel et al, 2012a) of depressive symptoms in cardiac patients, and this effect has been particularly attributed to Negative Affectivity (NA). Although some studies suggested that Type D is a stable construct (Denollet, 2005;Martens et al, 2007;Kupper et al, 2011;Romppel et al, 2012b), with conceptual (Denollet et al, 1996(Denollet et al, , 2010Denollet and Pedersen, 2008;Denollet and Conraads, 2011) and biological basis (Kupper et al, 2007) and not influenced by mood changes (Denollet et al 2005;de Jonge et al, 2007;Martens et al, 2007;Yu et al, 2010), others found that TDP was associated with depressive features (Kuijpers et al, 2007;Spindler et al, 2009;Dannemann et al, 2010;Svansdottir et al, 2012), general distress (Bergvik et al, 2010) and a history of depression (Martens et al, 2008;Starrenburg et al, 2013); with the stronger association (Kudielka et al, 2004;Bergvik et al, 2010;Coyne et al, 2011;Coyne and de Voogd, 2012;Howard and Hughes, 2012;Starrenburg et al, 2013;Tully and Penninx, 2012) found for NA.…”
