There is increasing interest among social and behavioral scientists in brief measures of attitudes and personality traits. Based on factor analysis and using an existing data set (n = 400 adults), we constructed a 5- and a 10-item version of the widely used animal attitude Scale (AAS). Both versions were highly correlated with the original 20-item AAS (rs > 0.95, p < 0.001), and both versions demonstrated acceptable reliability and validity. The AAS-5 and the AAS-10 have excellent psychometric properties and offer alternatives for researchers who need convenient and short measures of attitudes related to animal welfare.
