一套评价哮喘患者认知和行为问卷调查的有效性验证
2009/02/24
背景:多年来一直强调教育活动的重要性,因为成功医治哮喘有赖于患者对哮喘的认知和患者对哮喘的管理。然而在完成教育活动之前和之后,尚没有一项工具可以用来评价哮喘患者的认知和行为变化。
目的:验证一种问卷调查在检测参加教育活动的哮喘患者认知和行为中的有效性,检验教育活动的好处。
方法:通过文献报道、患者调查和临床现状研究形成哮喘行为变化(ABC)问卷。从8个方面评价7个不同的临床状况下患者的行为,从2个方面(病理生理和治疗)评价患者的认知。共有139名哮喘患者在教育活动过程中或之后完成了问卷调查。
结果:主成份分析证实,认知结构是通过临床现状经验性获得的。内部一致性分析显示克朗巴赫系数α值较高。不同方面和两个总体积分都能根据哮喘的严重程度区分患者。最后,教育活动前后差异的影响大小至少为0.47,大于两个总体行为和认知的评分(0.74)。第1次随访和第3位随访时受调查者总体行为和认知评分的差异分别达到了18.84±20.83(P<0.001,95%置信区间13.18-24.43)和11.06 ±14.98(P<0.001, 95%置信区间: 7.10-15.03)。
结论:ABC问卷调查是一项可以有效评价哮喘患者认知和行为的工具。而且,本研究证实,教育活动能使患者更好的认识哮喘。

Background: For several years, educational programmes have been highlighted because care success depends on patient’s knowledge and patient’s asthma management. However, no tool is available to assess change in patient knowledge and behaviour before and after completing an educational programme.
Objective: To validate a questionnaire measuring the knowledge and behaviour of asthmatics participating in an educational programme and to gauge the benefit of such a programme.
Methods: The Asthma Behaviour Change (ABC) questionnaire was generated from literature, patient surveys and clinical situations. It was organized in eight dimensions assessing patient behaviour in seven different clinical situations and two assessing patient (pathophysiology and therapeutic) knowledge. A total of 139 asthmatics filled out the questionnaire before, during and after the educational programme.
Results: The principal component analysis confirmed the structure empirically made by clinical situations. Internal consistency analysis yielded high Cronbach’s alpha values. Different dimensions and the two global scores were able to discriminate patients according to asthma severity. Finally, the effect size of difference before and after educational programme was at least 0.47, and was larger than 0.74 for both global behaviour and knowledge scores. The difference between visit 1 and 3 for global behaviour and knowledge scores reached 18.84 +/- 20.83 (P < 0.001, 95% CI: 13.18-24.43) and 11.06 +/- 14.98 (P < 0.001, 95% CI: 7.10-15.03), respectively.
Conclusion: ABC questionnaire is a valid tool to assess asthmatics’ knowledge and behaviour. Furthermore, this study confirmed that educational programmes lead to better awareness of asthma by patients.
