“…Other work suggests that dispositional negativity can promote mental illness by increasing the likelihood of experiences (e.g., loneliness, difficulty adjusting to university) and events (e.g., conflict, divorce, sickness) that, themselves, confer risk for internalizing illness in vulnerable individuals ( disposition → stressor × disposition → psychopathology ) (Abdellaoui et al, 2018; Clarke et al, 2018; Credé & Niehorster, 2012; Hengartner et al, 2018; Howland, Armeli, Feinn, & Tennen, 2017; Jocklin, McGue, & Lykken, 1996; Klimstra, Noftle, Luyckx, Goossens, & Robins, 2018; Matthews et al., in press; Overstreet, Berenz, Kendler, Dick, & Amstadter, 2017; Serrat, Villar, Pratt, & Stukas, 2018; Shackman et al, 2016c; Soto, in press ; Tackett & Lahey, 2017). Among individuals with a history of internalizing illness, higher levels of dispositional negativity are associated with a greater number of diagnoses and a more pessimistic prognosis (e.g., Buckman et al, 2018; Bufferd et al, 2016; Hengartner, Kawohl, Haker, Rossler, & Ajdacic-Gross, 2016b; Shackman et al, 2016c; Spinhoven et al, 2016; Struijs et al, 2018).…”
