Datasets and codebook for "Psychometric evaluation of the German Version of the Motivations to Eat Meat Inventory (MEMI)". Datasets for Sample 1 and Sample 2 are provided and the variables are described in the codebook. The Motivations to Eat Meat Inventory (MEMI) assesses four motives for eating meat: Natural, Necessary, Normal, and Nice. The aim of this study is a psychometric evaluation of the German MEMI. Two German-speaking samples (N=389; N=1,498) completed the MEMI online, one with an importance-based (sample 1), one with an agreement-based (sample 2) response format. We ran confirmatory factor analyses, tested measurement invariance, and examined validity. Across both samples, bifactor models showed the best model fit, with slightly better fit in sample 1 but acceptable fit in both formats. Measurement invariance across gender, age, and education largely supported factorial validity. Results suggested acceptable convergent validity. Regarding discriminant validity, a strong general factor underpinned responses, with Normal and Nice explaining meaningful additional variance. Nice meaningfully predicted meat consumption. The German MEMI is a valid tool to assess motivations to eat meat and best modeled with a bifactor structure.
