“…Different types of depressive symptoms and clusters differ in their prognostic value in persons with CHD, and considering depression as a multidimensional disorder in research on CHD has been advocated (Baune et al, 2012;Doyle, Conroy, McGee, & Delaney, 2010;Hawkins, Callahan, Stump, & Stewart, 2013;Stewart et al, 2012). Although somatic symptoms of depression have been suggested as most important as predictors of CHD, positive affect is acknowledged as the second most important cluster (Hawkins et al, 2013). Anhedonia (reduced positive affect) has received attention both as a prognostic (Damen et al, 2013;Denollet et al, 2007;Leroy, Loas, & Perez-Diaz, 2010) and etiological factor (Davidson, Mostofsky, & Whang, 2010;Edmondson, Newman, Whang, & Davidson, 2013).…”
