To mitigate emerging anthelmintic resistance (AR) in cattle, sustainable gastrointestinal nematode control strategies should be adopted. A multi-centre study was set up to understand the factors affecting European dairy cattle farmers' adoption of diagnostics and to gauge for differences between regions. The data were collected through a multi-lingual survey by participating countries of the European Co-operation in Science and Technology (COST) action COMbatting Anthelmintic Resistance in ruminants (COMBAR). Four countries provided sufficient data to be included in the data analysis: Norway, Italy, Germany and Austria. Three models were estimated and validated through structural equation modelling. Norway, along with Germany and Austria (pooled dataset) showed similar trends that align with previous studies. AR risk perception had no influence on the adoption intention of diagnostics, a positive influence was found for attitude towards diagnostics and subjective norms (i.e., perceived opinion of others), and a negative influence of attitudes towards anthelminthics. Additionally, routine (i.e., perception of the current treatment) had an indirect effect on adoption intention through attitudes. Italy's data deviated from these findings, presenting a positive effect of the perceived severity of AR, and perceived behavioural control (i.e., perceived ability to perform a specific behaviour) on adoption intention of diagnostics. Finally, Norway's data set allowed for inclusion of a measurement of current behaviour in the model, identifying a direct positive effect of the perceived actual behaviour of other farmers on their own behaviour.
为了减轻牛群中新兴驱虫药耐药性（AR）的影响，应采用可持续的胃肠道线虫控制策略。开展了一项多中心研究，以了解影响欧洲奶牛养殖户采用诊断方法的因素，并评估各地区之间的差异。通过参与欧洲科学技术合作组织（COST）行动“对抗反刍动物驱虫药耐药性”（COMBAR）的参与国家进行多语言调查收集数据。四个国家提供了足够的数据进行数据分析：挪威、意大利、德国和奥地利。通过结构方程模型估计和验证了三个模型。挪威与德国和奥地利（合并数据集）显示出与以前的研究一致的趋势。AR 风险感知对诊断的采用意向没有影响，对诊断的态度和主观规范（即他人的感知意见）有积极影响，对驱虫药的态度有负面影响。此外，常规（即对当前治疗的感知）通过态度对采用意向有间接影响。意大利的数据与这些发现不一致，表现出对 AR 严重程度的感知、对诊断采用意向的感知行为控制（即对执行特定行为的感知能力）有积极影响。最后，挪威的数据集允许在模型中纳入对当前行为的测量，确定其他农民感知到的实际行为对自己行为的直接积极影响。
