The inadequate awareness of livestock breeders on brucellosis transmission, as well as their improper knowledge about preventing brucellosis is considered as one of the important barriers to animal vaccination against brucellosis. The present study aimed to design and validate a brucellosis prevention questionnaire focused on animal vaccination. The valid questionnaire was used to design, implement, and evaluate an interventional training program.
A brucellosis prevention questionnaire (BPQ) was developed in the exploratory psychometric study. In addition, face-to-face interviews were conducted to formulate its initial items, the results of which were merged with those obtained from literature review. Further, the face, content, and construct validity of the questionnaire were assessed by co-operating livestock breeders, veterinarians, and health educationists. The impact score (IS), and content validity ratio (CVR) and index (CVI) of the items were calculated, and the construct validity of the questionnaire was evaluated through factor analysis. Furthermore, the reliability of the results related to the questionnaire was measured by using Cronbach's alpha, intra-class correlation coefficient (ICC), and composite reliability, as well as the standard error of measurement (SEM).
The questionnaire was finalized with 53 items and its validity was confirmed by CVI (0.90), CVR (0.74), and IS (4.30). Additionally, the items were loaded into three constructs of awareness, attitude, and practice. Further, the predictive power of awareness, attitude, and practice was determined as 43.43, 15.81, and 15.78%, respectively. Furthermore, the fitness of the proposed model among the constructs was confirmed by the root mean square error of approximation (RMSEA) < 0.08, as well as normed chi-square (× 2/ df) < 5.0, comparative fit index (CFI) ≥ 0.90, and Tucker- Lewis index (TLI) ≥ 0.9.
The brucellosis prevention questionnaire represented acceptable psychometric properties. The factors influencing the preventive behavior of livestock breeders can be identified by applying the questionnaire, and co-operating veterinarians and educational planners.
牲畜养殖者对布鲁氏菌病传播的认识不足，以及他们对预防布鲁氏菌病的知识掌握不当，被认为是动物布鲁氏菌病疫苗接种的重要障碍之一。本研究旨在设计并验证一份侧重于动物疫苗接种的布鲁氏菌病预防问卷。该有效问卷用于设计、实施和评估一项干预培训计划。
在探索性心理测量研究中编制了一份布鲁氏菌病预防问卷（BPQ）。此外，进行了面对面访谈以制定其初始项目，其结果与文献综述所得结果合并。此外，通过与牲畜养殖者、兽医和健康教育工作者合作，评估了问卷的表面效度、内容效度和结构效度。计算了各项目的影响得分（IS）、内容效度比（CVR）和内容效度指数（CVI），并通过因子分析评估了问卷的结构效度。此外，使用克朗巴哈系数、组内相关系数（ICC）、组合信度以及测量标准误（SEM）来测量与问卷相关结果的信度。
问卷最终确定为53个项目，其效度通过CVI（0.90）、CVR（0.74）和IS（4.30）得到确认。此外，这些项目被归入认知、态度和行为三个结构。此外，认知、态度和行为的预测能力分别确定为43.43%、15.81%和15.78%。此外，所提出模型在各结构之间的拟合优度通过近似均方根误差（RMSEA）<0.08、标准卡方（×2/df）<5.0、比较拟合指数（CFI）≥0.90和塔克-刘易斯指数（TLI）≥0.9得到确认。
布鲁氏菌病预防问卷具有可接受的心理测量特性。通过应用该问卷，并与兽医和教育规划者合作，可以确定影响牲畜养殖者预防行为的因素。
