Research output: Contribution to journalArticle

75 Scopus citations


The purpose of the present study was to meta-analytically investigate the score reliability for the Satisfaction With Life Scale. Four-hundred and sixteen articles using the measure were located through electronic database searches and then separated to identify studies which had calculated reliability estimates from their own data. Sixty-two articles met this criterion, providing 76 reliability coefficients. The articles comprising the sample were next coded to identify potential sample or test characteristics that might affect the variation in reliability estimates. Results indicate that score standard deviation, mean, percent female, US samples, English test version, and youth samples demonstrated significant relationships with score reliability. Results from this study provide useful information, in terms of scale performance, for researchers interested in using the measure for future academic endeavors.
