Abstract: Aim: The present study aims to develop the Race-related Attitudes and Multiculturalism Scale (RRAMS), as well as to perform an initial psychometric assessment of this instrument in a national sample of Australian adults. Methods: The sample comprised 2,714 Australian adults who took part in the 2013 National Dental Telephone Interview Survey (NDTIS), which includes a telephone-based interview and a follow-up postal questionnaire. We used Exploratory Factor Analysis (EFA) to evaluate the RRAMS’ factorial structure (n = 271) and then proceeded with Confirmatory Factor Analysis (CFA) to confirm the proposed structure in an independent sample (n = 2,443). Measurement invariance was evaluated according to sex, age and educational attainment. Construct validity was assessed through known-groups comparisons. Internal consistency was assessed with McDonald’s ΩH and ordinal α. Multiple imputation by chained equations was adopted to handle missing data. Results: EFA indicated that, after excluding 4 out of the 12 items, a two-factor structure provided a good fit to the data. This configural structure was then confirmed in an independent sample by means of CFA (χ2(19) = 341.070, p
