TLDR
The aim of the present study was to develop a short validated patient-completed questionnaire, the COPD Assessment Test (CAT), assessing the impact of COPD on health status, which has good measurement properties, is sensitive to differences in state and should provide a valid, reliable and standardised measure of COPd health status with worldwide relevance.Abstract:
There is need for a validated short, simple instrument to quantify chronic obstructive pulmonary disease (COPD) impact in routine practice to aid health status assessment and communication between patient and physician. Current health-related quality of life questionnaires provide valid assessment of COPD, but are complex, which limits routine use. The aim of the present study was to develop a short validated patient-completed questionnaire, the COPD Assessment Test (CAT), assessing the impact of COPD on health status. 21 candidate items identified through qualitative research with COPD patients were used in three prospective international studies (Europe and the USA, n51,503). Psychometric and Rasch analyses identified eight items fitting a unidimensional model to form the CAT. Items were tested for differential functioning between countries. Internal consistency was excellent: Cronbach's a50.88. Test re-test in stable patients (n553) was very good (intra-class correlation coefficient 0.8). In the sample from the USA, the correlation with the COPD-specific version of the St George's Respiratory Questionnaire was r50.80. The difference between stable (n5229) and exacerbation patients (n567) was five units of the 40-point scale (12%; p,0.0001). The CAT is a short, simple questionnaire for assessing and monitoring COPD. It has good measurement properties, is sensitive to differences in state and should provide a valid, reliable and standardised measure of COPD health status with worldwide relevance.read more

TL;DR: The CAT score may be predicted by factors related to COPD severity, depression and exercise capacity, with significant differences in the distribution of CAT scores in different countries.

Research trends and hotspots of health-related quality of life: a bibliometric analysis from 2000 to 2019.
TL;DR: In this paper, the authors explored the general trends and hotspots of health-related quality of life (HRQoL) articles published between 2000 and 2019 and performed a bibliometric analysis based on the number of articles, citations, published journals, authors' addresses, and keywords.

TL;DR: The COPD self-management educational intervention in FMCs reduced unscheduled visits to the clinic and improved patients’ quality of life, self- management skills, and knowledge.

TL;DR: Impaired pulmonary function was associated with the 6MWT score and limitations on performance-based and self-reported mobility activities, but not with skeletal muscle strength among elderly COPD patients.

TL;DR: The findings suggest that wheezing and COPD assessment test score are related to the prescription of ICS in patients with chronic obstructive pulmonary disease in Taiwan.

Coefficient alpha and the internal structure of tests.
TL;DR: In this paper, a general formula (α) of which a special case is the Kuder-Richardson coefficient of equivalence is shown to be the mean of all split-half coefficients resulting from different splittings of a test, therefore an estimate of the correlation between two random samples of items from a universe of items like those in the test.

Chronic obstructive pulmonary disease surveillance--United States, 1971-2000.
TL;DR: In this article, the authors present national data regarding objectively determined COPD (1971-1994), COPD-associated activity and functional limitations (1980-1996), self-reported COPD prevalence, COPD physician office and hospital outpatient department visits, and COPD hospitalizations, and deaths.
Journal Article
Chronic obstructive pulmonary disease surveillance--United States, 1971-2000.
TL;DR: The proportion of the population aged < 55 years with mild or moderate COPD, on the basis of pulmonary function testing, decreased from 1971-1975 to 1988-1994, possibly indicating that the upward trends in COPD hospitalizations and mortality might not continue.
