| Summary: | Measuring human consumption of animals and animal products (HCAAP) is challenging but often important for researchers and animal rights advocates. We contribute to measuring HCAAP by conceptualizing that consumption as a trait. In 3 studies, we analyzed responses from traditional Food Frequency Questionnaires and created two measures of HCAAP traits based on 24-hour and 3-month self-reports. Studies 1 (N = 249) and 2 (N = 265) evaluated the item-level properties of 24-hour and 3-month self-reports, eliminating items that were not likely to provide much information about the underlying trait of HCAAP. Study 3 (N = 252) provided evidence that the two measures were predicted by knowledge of animals as food, meat-eating rationalizations, numeracy, sex, and political orientation. These results suggest that the two instruments could be used to measure HCAAP as a trait. We offer suggestions as to when using the two instruments may be beneficial.
