慢性阻塞性肺疾病患者生活质量与自我效能相关性研究

目的:探讨慢性阻塞性肺疾病(COPD)患者生活质量与自我效能的相关性。方法:于2011年4-11月采用便利抽样的方法,选取广州市某医院病情稳定、准许出院的患者和门诊患者进行调查,分别使用圣乔治呼吸问卷和COPD自我效能量表对患者的生活质量和自我效能进行测评。结果:COPD患者生活质量的症状评分与自我效能的负面影响、极端的情绪激动、体力活动、天气/环境维度评分均具有相关性(r=0.28～0.33,P<0.05)。COPD患者生活质量的活动评分、影响评分及总分评分与患者自我效能的各维度评分均具有相关性(r=0.38～0.58,P<0.01)。结论:COPD患者的生活质量与自我效能存在关联,患者的自我效能水平越高,其生活质量也越高,提示可以从提高患者的自我效能水平着手,改善COPD患者的生活质量。

The correlation between quality of life and self-efficacy in patients with chronic obstructive pulmonary disease

Objective： To determine relationship between quality of life and self-efficacy in patients with chronic obstructive pulmonary disease （COPD）. Methods： Convenience sampling of 68 patients with COPD were assessed with the St George＇s Respiratory Questionnaire （SGRQ） and the Chinese modified COPD Self-Efficacy Scale （CSES） respectively. Results： The score of the SGRQ symptom component showed significant correlation with the scores of the CSES negative effect, intense emotional arousal, physical activity, and weather/environmental components （r=0.28-0.33, P〈0.05）. The scores of the SGRQ activity, impact and total domains all showed significant associations with scores of all domains of the CSES （r=0.38-0.58, P〈0.01）. Conclusions： Quality of life of patients with COPD has significant correlation with their self-efficacy level, with high self-efficacy predicting good quality of life.
