Objective: To develop a Chinese cultural background of bronchial asthma quality of life scale (quality of life scale for patients with asthma), and evaluate its reliability, validity, and responsiveness. Influencing factors of asthma patients' quality of life, the quality of life in patients with treatment options to provide a reference for comprehensive evaluation of asthma. Scale system of common modules and specific modules combine thinking method: determination based on the quality of life of patients with chronic diseases, on the basis of the review of the literature, combining the characteristics of China's culture, through focus groups focus on the statistical analysis combined with clinical practice, the use of Scale Development program decision-making developed scale. Scale Chinese, through translation and back translation, cultural adaptation step form SF-36 British development version. January 2010 to December 2010 using the above two scale survey of 100 patients with asthma Assessment Scale, reliability, validity and responsiveness, while collecting the objective indicators of asthma patients, the analysis of the quality of life of patients with asthma factor. Throughout the course of the study used statistical methods including statistical description, correlation analysis, paired t-test, to explore the factor analysis, multiple linear regression analysis. Results: (1) through research, developed chronic diseases constituted by the common module of 36 entries and 17 entries in the specific module measuring quality of life scale system of bronchial asthma the scale QLICD-BA. (2) Scale QLICD-BA evaluation results show that the scales have good test-retest reliability, in addition to physical function, specific modules Scales reliability, split-half reliability is better; correlation analysis and factor The analysis showed good construct validity; after treatment in all areas except small aspects of the social security and the total scale score were statistically significant, can basically reflect changes in the quality of life before and after treatment. (3) The feasibility: the vast majority of patients can be completed within 15 to 20 minutes Scale. Questionnaire recovery was 97%, wherein the integrity of the gauge was 96.3%, so the scale in clinical good feasibility. (4) impact of quality of life factors for multiple linear regression analysis, the results showed that asthma objective indicators of the quality of life is not high, multiple linear regression analysis showed that gender, age, ethnicity, marital status, occupation, education level, since rated family economic status, the form of medical insurance, treatment, lung function and other indicators of quality of life score related. Conclusion: Quality of Life Scale system of chronic disease in patients with bronchial asthma Scale QLICD-BA has a good reliability, validity, and responsiveness, as the evaluation of the quality of life of patients with asthma tools. Objective indicators and subjective indicators is not highly relevant, objective indicators and comprehensive response to the quality of life of patients with asthma. Factors that affect the quality of life of patients with asthma, gender, age, ethnicity, marital status, occupation, education level, family economic status, the form of medical insurance, treatment, pulmonary function, self-assessment.
