“…There is additional evidence from similarly rigorous research that trait EI training has long‐term (lasting for at least 1 year) beneficial effects in terms of reducing perceived stress levels, somatic complaints, and even diurnal cortisol secretion, a biological marker for stress (Kotsou, Nelis, Gregoire, & Mikolajczak, ). Preliminary research with young adolescents has suggested that cognitive behavioral group‐work (Ruttledge & Petrides, ) or yoga interventions (McIlvain, Miller, Lawhead, Barbosa‐Leiker, & Anderson, ) can have positive effects on trait EI scores (see also Khalsa, Greiner‐Ferris, Hofmann, & Khalsa, ). Collectively, this evidence is important both for its practical consequences in people's lives and for what it implies about the causal effects of trait EI on a range of psychological and behavioral outcomes.…”
