Character strengths have been found to be predictive of high levels of life satisfac tion. The present study attempts to examine the relationship between these constructs but at a fine-grained level. To that end, we used the heart versus mind classification of character strengths (Peterson, 2006), scarcely examined in prior research, to test whether affective component traits (heart strengths) are more linked to life satisfaction than cognitive-component traits (mind strengths). A sample of 419 undergraduate students completed the measures of character strengths and life satisfaction. Statistical analysis showed that affective-component traits were more predictive of life satisfaction than cognitive-component traits. These findings emphasize the need to devise strength-based interventions aimed at improving life satisfac tion, specifically addressing heart character strengths. Implications of these findings for future research are discussed.
