“…Expressing positive emotions typically attracts social interaction and maintains positive social relationships (Fredrickson & Cohn, 2008; Shin et al, 2011; Sroufe, Schork, Motti, Lawroski, & LaFreniere, 1984). Positive expressivity has often been associated with greater social competence in childhood (Denham et al, 1990; Hernández, Eisenberg, Valiente, Spinrad, et al, 2017; Shin et al, 2011), and been negatively associated with externalizing behaviors (Buss, Kiel, Morales, & Robinson, 2014; Kim, Walden, Harris, Karrass, & Catron, 2007; Stifter, Putnam, & Jahromi, 2008) and internalizing symptoms (Dougherty, Klein, Durbin, Hayden, & Olino, 2010; Ghassabian et al, 2014; Olino et al, 2011; Walter & LaFreniere, 2000). These studies suggest that positive affect is associated with lower maladjustment, consistent with theory on emotion and psychopathology (Clark & Watson, 1991; Lonigan, Phillips, & Hooe, 2003).…”
