摘要目的:探讨肺癌患者疾病感知、患者积极度、自我管理三者间的关系，并分析患者积极度在疾病感和自我管理间的中介作用。方法:采用便利抽样法抽取255例住院的肺癌患者，运用一般资料调查表、疾病感知问卷简化版(brief illness perception questionnaire，BIPQ)、患者积极度量表(patient activation measure，PAM13)和癌症患者自我管理测评量表进行调查，采用SPSS 26.0对资料进行统计学分析。使用 t检验、方差分析、Pearson相关分析、中介效应检验等进行数据分析。 结果:肺癌患者的疾病感知评分为(41.91±7.94)分，患者积极度评分为(62.31±16.39)分，自我管理评分为(142.20±20.59)分；肺癌患者的疾病感知与患者积极度和自我管理均呈显著负相关( r＝-0.652， P<0.01； r＝-0.762， P<0.01)，患者积极度和自我管理呈显著正相关( r＝0.746， P<0.01)；患者积极度在疾病感知和自我管理间的中介效应占总效应的37.10%。 结论:患者积极度在肺癌患者疾病感知和自我管理间起部分中介作用，是患者主动参与到疾病自我管理的重要保护性因素。医护人员可在评估肺癌患者疾病感知和积极度的基础上，对负性疾病感知及时进行纠正，帮助其建立并维持高积极度水平，以改善其自我管理。

abstractsObjective:To explore the relationship among illness perception, patient activation and self-management in patients with lung cancer, and to investigate the mediating effect of patient activation between illness perception and self-management.Methods:A total of 270 inpatients with lung cancer were selected by convenience sampling method.They were investigated by self-made social demographic questionnaire, brief illness perception questionnaire(BIPQ), patient activation measure(PAM13)and cancer patient self-management scale.SPSS 26.0 software was used for data analysis.T-test, analysis of variance, Pearson correlation analysis and mediating effect test were used for statistical analysis.Results:A total of 255 questionnaires were collected effectively.The total score of illness perception, patient activation and self-management in patients with lung cancer were (41.91±7.94), (62.31±16.39)and (142.20±20.59) .The total score of illness perception of lung cancer patients was significantly negatively correlated with the total score of patient activation and patient self-management( r=-0.652, P<0.01; r=-0.762, P<0.01), and the total score of patient activation was significantly positively correlated with the total score of self-management in patients with lung cancer( r=0.746, P<0.01). Patient activation had a partial mediating effect between illness perception and self-management in patients with lung cancer, and the mediating effect accounted for 37.10% of the total effect. Conclusion:Patient activation plays a partial mediating role between illness perception and self-management in lung cancer patients, and it is an important protective factor for patients to actively participate in self-management of disease.On the basis of assessing the illness perception and patient activation of lung cancer patients, medical staff can timely correct the negative illness perception and help them establish and maintain a high positivity level to improve their self-management.
