| BackgroundCoronary heart disease as a common Clinical disease,a serious threat to human health,is the most developed and many developing countries the leading cause of death for adults。At present,for the treatment of coronary heart disease research methods,it is mainly concentrated in the evaluation of symptom improvement,but with the medical model of change,simply it is difficult to rely on a comprehensive evaluation of the main symptoms of the disease treatment。Coronary heart disease patients one of the main objectives is to improve the quality of life(QOL),and thus how to assess coronary heart disease rehabilitation QOL studies are one of the hotspots。Over the years, the application of the general population epidemiologists rating scale for quality of life in patients with various diseases were measured,and the field of cardiovascular QOL scale were mainly centered on high blood pressure,chronic heart failure and cardiac transplantation,the lack of QOL for patients with coronary artery disease Scale。Scale also exist at home and abroad culture,social background and values of the difference between Chinese and Western medicine on the disease and health awareness methods,the adoption of such a scale difficult to objectively evaluate the clinical efficacy of Chinese medicine and the impact of Chinese medicine in treatment of coronary artery disease popularization and application,so suitable for building a comprehensive evaluation of the condition of our country the quality of life in patients with coronary artery disease is necessary scale。Objective Combination of health and quality of life in patients with coronary artery disease on coronary heart disease in self-control-made quality of life,scale entry should be screened for the development of a unique combination of Chinese and Western Medicine Quality of Life Scale for patients with coronary artery disease and has been used in traditional Chinese and western medicine treatment ofcoronaryheartdisease(Traditional Chinese Medicine after revascularization intervention) patients,on the scale reliability,validity and responsiveness evaluation。Thus the initial set up for evaluating the clinical efficacy of coronary heart disease in patients with traditional Chinese and western medicine table features quality of life for patients with coronary heart disease in self-evaluation and evaluation of the therapeutic effect of providing a quantitative criteria。Methods1 DesignTo take cross-sectional longitudinal study with follow-up study of a combination of forward-looking approach。2 Study sites and objectsScale investigate Guangzhou City inpatients at Guangdong Provincial TCM Hospital,First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine,Guangdong Provincial People's Hospital and healthy people, scale investigation into the preparation of patients with coronary artery disease and healthy population。Scale evaluation studies in coronary heart disease after revascularization in patients with Chinese medicine intervention,research subjects into the diagnosis,inclusion criteria excluded。3 Scale preparation and appraisal programsUsed by domestic and international scale study research methods,According to the study of scale goals and principles,References recognized at home and abroad,there is good reliability,validity,responsiveness of the scale on the basis of entries,Chinese medicine combined with the clinical characteristics of coronary heart disease,screening the entry form the entry pool。People through health and quality of life in patients with coronary artery disease investigation,the importance of the application of the expert score, and discrete trends in law,discriminant analysis,factor analysis,stepwise regression,discriminant,Cronbach'a analysis method on the scale screening, Forming characteristics of traditional Chinese and western medicine in patients with coronary heart disease quality of life scale。Again in line with survey research,applied a series of statistical methods to scale the feasibility,reliability,validity and responsiveness evaluation。Results1 Scale CharacteristicsCoronary heart disease combined with the characteristics of Chinese and Western medicine in order to scale study to examine methods to set up the entry pool filter,established by the four domains,composed of 34 entries in the initial coronary heart disease in the Quality of Life Scale Integrated Traditional and Western Medicine。Investigate on the scale through factor analysis of statistical methods,to retain the reentry screening,the formation of Chinese and Western medicine symptoms of domain eight entries, five entries in the physical domain,the psy- chological domain of five entries, three entries in the social domain of coronary heart disease of Traditional Chinese and Western Medicine formal quality of life Scale,Scale for coronary heart disease-specific scale,belong to rating scale to assess for self-assessment。2 Scale evaluation2.1 feasibilityScale of the recovery was 100%。Scale finish time for 4-16 minutes,with an average of 11.36 minutes。Scale at the testing process apart from 6.6 percent ill- iteracy because they do not understand the content at the help investigators fill in the remaining subjects are able to understand and to fill in the correct scale.2.2 Scale ReliabilityCronbach:Coronary heart disease in traditional Chinese and western medicine symptoms of quality of life scale domains,physical domains, psychological domain,social domain and the total table's coefficients were 0.765,0.890,0.847,0.853,0.936;split-half reliability:four domains and the total table split-half reliability coefficients were 0.753,0.839,0.847,0.616,0.912;test-retest reliability:the four domains and the overall evaluation form on both sides of the correlation coefficients were for 0.970,0.984,0.980,0.971,0.988。Better reliability。2.3 Scale Validity Content Validity:Of all entries with the domain,the domain table and the total scores between the correlation analysis,the results show:Symptoms and Symptom Domains of entries of the correlation coefficient between the domains at between 0.384 to 0.813,physical domain of the entry and physiology domain between the correlation coefficient at 0.676 to 0.937 between the psychological domain of entries with the psychological domain of the correlation coefficient between at between 0.671 to 0.876,social domain and social domain of entry between the correlation coefficients at 0.815 to 0.921 between the domain table with the total at between the correlation coefficient from 0.817 to 0.925 between the scale has good content validity;Construct Validity:Inventory data by factor analysis,based on the cumulative contribution rate of over 70%and》1 eigenvalue two factors extracted five principal components,the cumulative contribution rate of 73.08%,factor of the entries in line with the scale of the composition of the basic theory the concept of social domain in addition to the entries in the common factor in all the load on a relatively small addition to other factors have been a better professional interpretation,validity of the scale structure better;standard related validity:The Seattle Heart Colic Scale(SAQ) as the criterion, respectively,of patients with simultaneous measurements and related data analysis to test the scale of standard-related validity.The results of the analysis showed a correlation coefficient of 0.901,p＜0.01,there is a strong correlation,it shows that the scale has a strong standard-related validity。2.4 Scale responsivenessHealthy people and patients with coronary heart disease symptoms domains,physical domains,psychological domains,social domains,scores for both t test P less than 0.01,that is,the difference was significant,indicating that the scale has distinction between health and quality of life in patients with coronary artery disease capacity;revas- cularization of patients with coronary artery disease before and after comparison of quality of life,t test results showed that the symptoms of the two evaluation domains,physical domains,psychological domain,social domain and the difference between total scores was significant。ConclusionThe development of this scale in accordance with the concept of coronary heart disease,in theory,under the guidance of Chinese and Western medicine, according to the characteristics of coronary heart disease,Established coronary heart disease rating scale theoretical framework,that is,scale from Chinese and Western medicine symptoms,physiological,psychological,social composition of the four domains。In accordance with the psychometric approach to scale development,And through clinical evaluation,Scale at the development,clinical trial and evaluation to further improve the scale formulate methods and procedures and so on,are more comprehensive from the quantitative point of view reflects the connotation of patients with coronary artery disease。1.The present study,In complying with the general quality of life measures and steps at the same time,Scale based on the various steps in the development of the traditional methods of decomposition,composition,Certain steps will be further refined,deepened,specialization,Steps to form a clearer and more specific,easier to scale operations to develop methods of quality of life, And in the study has targeted the introduction of the characteristics of quality of life study of statistical methods。2.In accordance with the scale of the measures and steps to develop research, Substantial collection of experts and the patient developed on the scale of the various views,Training for investigators,Carefully to the patient advocacy work,Comply with the principles of clinical research,quality control and regular check-ups from time to time a number of ways,Study on the scale to ensure the smooth progress of the quality and scale。3.The scale used in the preparation of multi-domainal approach,including Chinese and Western medicial symptoms,physiological,psychological,social four domains,So that scale can be reflected in coronary heart disease symptoms characteristic of Western medicine and the special does not apply,such as satisfaction and efficacy。After screening the entry of experts with many additions and deletions sick,modify,merge,adapt,By the importance score,the correlation coefficient method,the degree of dispersion method,factor analysis,discrimination analysis,'s coefficient method to filter entries, So greatly improve the quality of entries,more in line with the needs of clinical application。The formation of the above four domains,a total of 21 patients with coronary artery disease,were the purpose of determination of the quality of life scale。Scale-based self-assessment,Domains of the main results of analysis and statistics in various domains can be independent and is conducive to comparative study of the clinical classification。4.The recovery rate of the questionnaire and response rates are higher,The time required to complete a questionnaire for 4-16 minutes,indicating that the table has a high feasibility。5.Clinical evaluation of reliability,validity and responsiveness the results of the analysis indicate that this scale has good internal consistency reliability,split-half reliability,test-retest reliability,that scale has good stability,consistent cross-entries nature,accuracy,scale entry very good internal consistency。At the same time scale has good content validity,an appropriate standards-related validity,Showing the better correlation domain,structural part of the area of validity need to re-adjust,but overall a good construct validityo Noting scale with high accuracy,validity and correctness。6.This scale can distinguish between different groups(healthy people and stroke patients) the changes in quality of life,distinguish between different interventions have different effects due to the ability to even distinguish between different groups and differences in the horizontal extent of the information,information on various quality of life more sensitive to changes in scoring,with good responsiveness。...
