“…It further has shown high correlations with measures of theoretically related constructs, such as resilience (r ϭ .45; Smith et al, 2008), optimism (rs range from .47 to .62 in four studies; Scheier & Carver, 1985), self-esteem (rs range from .53 to .58 in four studies; Rosenberg, 1965), extraversion (r ϭ .36; Eysenck & Eysenck, 1975), and positive emotionality (r ϭ .48; Tellegen, 1985), suggesting that happiness is related, but not equivalent, to these constructs. For more detailed information on this measure, see Lyubomirsky and Lepper (1999). of feedback (relative failure-relevant, relative failure-nonrelevant, and control). In the relative failure-relevant condition (ns ϭ 10 and 13, for the unhappy and happy groups, respectively), the confederate solved anagrams at a much faster pace than the participant, and the participant was led to believe that this other "subject" was solving the same number of anagrams as him or her.…”
