“…Trait negative emotionality is relatively stable from infancy through adulthood (Lonigan, Phillips, & Hooe, 2003;Pedlow, Sanson, Prior, & Oberklaid, 1993;Roberts & DelVecchio, 2000;Rothbart, Ahadi, & Evans, 2000), this stability is genetically mediated (e.g., Spengler, Gottschling, Spinath, 2012), and associations between NErelated constructs and psychopathology begin early in development. Dispositional measures of 9 negative emotions, such as tendencies toward sadness, anger, irritability, and frustration, have been associated with internalizing and externalizing problems in young children (Eisenberg et al, 2001), preadolescents (Anthony & Lonigan, 2002;Oldehinkel, Hartman, Winter, Veenstra, & Johan, 2004), and adolescents (Silk, Steinberg, & Morris, 2003). Measures of negative emotions early in childhood prospectively predict higher levels of psychopathology in late adolescence (Block, Gjerde, & Block, 1991) and young adulthood (Caspi, Moffitt, Newman, & Silva, 1996), and negative emotionality in late adolescence predicts subsequent development of major depression in adulthood (Wilson, DiRago, & Iacono, 2013).…”
