慢性阻塞性肺疾病患者生命质量测定量表的研制与考评

Development and Evaluation of Quality of Life Rating Scale for Patients with Chronic Obstructive Pulmonary Disease

目的研制慢性阻塞性肺疾病（COPD）患者生命质量测定量表,并对其进行考评。方法采用量表开发的程序化决策方式研制适合中国文化的COPD患者生命质量测定量表,并通过测定86例COPD患者的生命质量对量表进行评价。结果该量表的内部一致性信度α值为0.93,重测信度r值为0.94,分半信度为0.84;各领域内部一致性信度α值及重测信度r值大多在0.6以上;各条目与其所在领域的相关均大于与其他领域的相关,相关系数r值大多在0.5以上;该量表在入院治疗后基本上能够反映出生存质量的变化;绝大多数患者能在15-20min完成测定。结论COPD患者生命质量测定量表（QLICD-COPD）具有较好的信度、效度、反应度和临床可行性,可以作为我国COPD患者生命质量的测评工具。

Objective To develop a quality of life rating scale for patients with chronic obstructive pulmonary disease （COPD）. Methods The programmed decision making mode was used to develop a scale consistent with Chinese cultural background for rating the life quality of COPD patients, then the scale was assessed by analyzing the data from 86 patients with COPD. Results The α value of the coefficients of internal consistency, r value of the test - retest reliability and the value of split - half for the scale were 0. 93, 0. 94 and 0. 84 respectively ; most of internal consistency and test - retest reliability for each domain were above 0. 6 ; most of correlation coefficients between each item and its domain were above 0. 5 ; The measurement had the ability to detect clinical change due to treatment; Most of the patients could finish the questionnaire in 15 -20 minutes. Conclusion The QLICD - COPD is of valid, reliable, sensitive and feasible operation in clinical settings, and it can be used in China to assess quality of life for patients with COPD.
