Development and validation of the living with chronic obstructive pulmonary disease questionnaire

Abstract

The LCOPD is a new measure examining the everyday impact of living with COPD. It demonstrates good scaling properties and may prove valuable in understanding treatment benefits.

Usefulness of the LCOPD, CAFS and CASIS Scales in Understanding the Impact of COPD on Patients

“…The LCOPD questionnaire which measures the overall impact of COPD as perceived by the patient is a validated instrument consisting of 22 items, which in addition to its good psychometric properties has the advantage of being easy and quick to complete [24]. We have established its discriminating power with respect to the severity of airflow obstruction, degree of dyspnea, presence of respiratory symptoms, and other aspects previously reported using other questionnaires, such as the frequency of exacerbations [33,34], level of education [35], physical activity [36,37], and presence of anxiety or depression [38].…”

“…The LCOPD consists of 22 items that identify a wide range of situations where COPD could negatively impact daily life. An overall score is obtained ranging from 0 to 22, where high scores indicate a major impact of COPD on daily life [24]. …”

“…For this reason, two specific instruments have recently been developed and validated for patients with COPD: the COPD and Asthma Fatigue Scale (CAFS) [22] and the COPD and Asthma Sleep Impact Scale (CASIS) [23]. The Living with COPD (LCOPD) questionnaire is a new instrument that measures the overall impact of COPD on daily life [24]. The objectives of the current study were to assess the usefulness of these new instruments and to identify factors associated with the concepts they measure.…”

The living with chronic obstructive pulmonary disease scale was successfully adapted for use in Southern European (Italian and Spanish) and Eastern European (Russian) cultures

“…The U.K. and U.S. versions of the measure, which were developed in parallel, have been well accepted by respondents, are unidimensional and easy to administer, complete and score. These versions have good consistency, reproducibility, and construct validity [7]. As the LCOPD was primarily developed for use in international clinical trials, it is necessary to develop additional language versions of the scale.…”

“…This led to the development of the Living with COPD (LCOPD) questionnaire, a unidimensional scale assessing the holistic impact of COPD and its treatment on patients [7]. The LCOPD adopted the needsbased model of QoL [8]dthe most widely applied in health research [9].…”
