We comprehensively measured individual differences in aesthetic interest by developing The Desire for Aesthetics Scale (DFAS). In Study 1, a 40-item scale was given to 71 undergraduates. Based on item-total correlations, the worst items were revised or dropped, and new items were created. In Study 2, a 43-item scale was tested with 99 undergraduates from two colleges, and was given to one group 3 months later, demonstrating adequate test-retest reliability scores ( r = .74). In Study 3, a revised 42-item scale was given to 62 older, non-students. For the combined relevant samples from Study 2 and Study 3 ( N = 110), the final 36-item DFAS yielded good internal consistency ( alpha = .82, p < .001 compared to a test value of .70; 95% confidence interval: (0.764, 0.865)). Overall, in multiple samples, this scale resulted in reliable measurements of individual differences in motivation to seek out and care about a wide range of aesthetic stimuli.
