Behavioral change interventions promoting the reduction of animal product consumption are valuable tools to improve ecological sustainability as well as public health and help the mitigation of climate change. Recent findings revealed improved efficacy of interventions targeted at barriers (e.g., self-efficacy) of three different types of meat consumers over non-targeted interventions (e.g., completion of unrelated surveys). However, such interventions have yet to factor in the role of individual differences in personality. Therefore, in a first step, we performed segmentation analysis on barriers and benefits of reducing animal product consumption (e.g., meat attachment, environmentalism) with the inclusion of personality. In an online sample of N=1135 participants, latent profile analysis revealed five distinct dietary groups: "plant-based eaters", "meat-reducers", "medium-hindrance meat eaters", "medium strong-hindrance meat eaters, and "strong-hindrance meat eaters", based on inhibitors and facilitators of meat reduction. Groups differed in terms of consumption of different animal products (η2=0.08 to η2=0.80) as well as the Big Five (η2=0.08 to η2=0.80) and Dark Triad (η2=0.08 to η2=0.80). Strong-hindrance meat eaters were characterized by low Conscientiousness, Agreeableness, and Openness as well as high dark trait expression, implying new targets for future intervention design.
促进减少动物产品消费的行为改变干预措施是改善生态可持续性以及公共健康和帮助缓解气候变化的有价值的工具。最近的研究结果表明，针对三种不同类型的肉类消费者的干预措施（例如，自我效能感）比非针对性干预措施（例如，完成不相关的调查）更有效。然而，这些干预措施尚未考虑到个性差异的作用。因此，我们首先在包括个性的情况下，对减少动物产品消费的障碍和益处（例如，肉类依恋、环保主义）进行了细分分析。在一个包含 N=1135 名参与者的在线样本中，潜在剖面分析根据减少肉类的抑制剂和促进剂揭示了五个不同的饮食群体：“纯素食者”、“肉类减少者”、“中等障碍肉类食用者”、“中等强障碍肉类食用者”和“强障碍肉类食用者”。这些群体在不同动物产品的消费方面存在差异（η2=0.08 到 η2=0.80），以及大五人格（η2=0.08 到 η2=0.80）和黑暗三人格（η2=0.08 到 η2=0.80）。强障碍肉类食用者的特点是责任心、宜人性和开放性较低，以及黑暗特质表达较高，这意味着未来干预设计的新目标。
