This study investigated whether gratitude and the "good-enough mindset" added to the contribution of perfectionism in predicting life satisfaction in 245 Chinese highly achieving students in Hong Kong. Participants completed self-report questionnaires that included scales on life satisfaction, positive and negative perfectionism (perfectionistic striving and perfectionistic concerns), gratitude and the good-enough mindset. Measures of gratitude and the good-enough mindset explained a substantial amount of unique variance in the prediction of life satisfaction in addition to the contribution of age and measures on positive and negative perfectionism. Implications of the findings for integrating gratitude and the good-enough mindset in the development of effective positive interventions to cope with negative perfectionism in youth and adolescents are discussed.
