“…A high level of dispositional optimism has been associated with better mental and physical health, as well as with more protective practices, and resilience to stressful life events on samples of adults (see Carver et al, 2010;Rasmussen, Scheier, & Greenhouse, 2010 for reviews). Previous studies also showed that dispositional optimism is related to various indices of the adolescents' positive adjustment, such as healthcare attitudes, physical and psychological quality of life, or motivation to pursue their goals (e.g., Jones, DeMore, Cohen, O'Connell, & Jones, 2008;Mannix, Feldman, & Moody, 2009;Huan, Yeo, Ang, & Chong, 2006). Recent research suggests that optimism is a modifiable variable that can be developed in adolescents through certain psychological interventions, becoming a stable personality trait throughout adulthood (Mannix et al, 2009;Tusaie & Patterson, 2006).…”
