社区慢性阻塞性肺疾病患者自我效能影响因素研究

目的探讨慢性阻塞性肺疾病（COPD）患者自我效能相关影响因素，为提高患者自我疾病管理水平提供依据。方法2008年10月至2009年3月，以方便抽样方法筛选上海某社区320例COPD患者，通过现场问卷、量表调查和肺功能检查，了解COPD患者自我效能相关影响因素。结果社区COPD患者自我效能总分（74．24±9．50）分，286例（89．4％）为中度水平自我效能。将疾病知识、社会支持、第一秒用力呼气容积占用力肺活量百分数（FEV1／FVC）、自我管理行为进人回归方程，可解释因变量全部变异的57．1％。结论疾病知识、社会支持、FEV1／FVC、自我管理行为是影响患者自我效能的主要因素；应通过提高患者疾病知识、加强心理护理及社会支持等措施，促进患者自我效能水平的提升。

Influencing factors of self-efficacy among community-based patients with chronic obstructive pulmonary disease

Objective To investigate the self-efficacy levels and its influencing factors of community-based patients with chronic obstructive pulmonary diseases （COPD） . Methods From October 2008 to March 2009, 320 community COPD patients were recruited from a Shanghai community. They undertook questionnaires, scale survey and pulmonary function testing so as to investigate the influencing factors of self-efficacy. Results The total scale of self-efficacy was 74. 24 _＋ 9. 50 and the level of self- efficacy in 286 cases（ 89. 4% ） was intermediate. The knowledge of COPD, social supports, forced expiratory volume at 1 second （ FEVl ）/forced vital capacity （ FVC ） and self-management level were entered into regression equation and could explain 57. 1% of the total variance of independent variables. Conclusions The knowledge of COPD, social supports, FEV1/FVC and self-management level are the major influencing factors of self-efficacy in the COPD patients. We should improve the knowledge of disease and strengthen the psychological care and social supports so as to improve their quality of life.
