摘　　要：目的利用结构方程模型分析山东省肺结核患者痰液处置知识、态度、行为之间的关系,结合中国现阶段针对肺结核患者痰液等废弃物的管理和督导现状,提出具有实践价值的相关改进措施和管理策略。方法采用多阶段分层整群随机抽样的方法,抽取了山东省3个市内6个县(区)总计800例肺结核患者进行问卷调查。结果肺结核患者的痰液处置认知对其痰液处置行为有显著的直接效应(r=-0.414);痰液处置行为对其外出时的保护措施也有显著的直接效应(r=-0.307);痰液处置认知通过痰液处置行为对外出时采取的保护措施有显著的间接效应(r=0.127)。结论可通过提升肺结核患者对痰液处置的认知来对其痰液处置行为产生影响,进而使患者倾向于采取正确的痰液处置方式,养成良好的痰液处置行为。Objective To examine relationships among knowledge, attitude and behavior about sputum disposal in pulmonary tuberculosis patients for making management policies. Methods Totally 800 pulmonary tuberculosis patients were selected from 6 counties or districts in Shandong province with multistage random cluster sampling and a question- naire survey was conducted among the patients. Structural equation model was adopted in data analyses. Results The cognition on sputum disposal showed a significant direct affect on sputum disposal habit among the pulmonary tuberculo- sis patients with chemotherapy at home （ r = - 0. 472）. Spatum disposal habit showed a significant direct effect on out- home protective with measure among the pulmonary tuberculosis patients （ r = - 0. 495 ）. The cognition on sputum disposal showed a significant indirect effect on out-home protective measure among the pulmonary tuberculosis patients through the mediation of sputum disposal habit （ r = - 0. 472 × - 0. 495 = 0. 234）. Conclusion Correct sputum disposal could be promoted through the improvement in cognition on sputum disposal among pulmonary tuberclosis patients.
