“…Trait gratitude measures are strongly correlated with various measures of subjective well-being (e.g., McCullough, Emmons, & Tsang, 2002;Watkins, Woodward, Stone, & Kolts, 2003b;Wood, Joseph, & Maltby, 2008), longitudinal studies have found that gratitude predicts increased well-being over time, and gratitude is one of the strongest predictors of happiness amongst the strengths identified by the Values In Action project (Park, Peterson, & Seligman, 2004;. Furthermore, experimental studies have provided promising evidence that gratitude exercises may actually enhance immediate mood state (Watkins et al, 2003b), and long-term subjective well-being (Emmons & McCullough, 2003;Froh, Sefick, & Emmons, 2008;Lyubomirsky, Sheldon, & Schkade, 2005;Seligman, Steen, Park, & Peterson, 2005, for a review, see Watkins, Van Gelder, & Frias, 2009). Thus, not only is there a strong tendency for grateful individuals to be happy, but now there also appears to be some evidence that gratitude causes enhanced subjective well-being.…”
