Creation of the SAQ-COPD Questionnaire to Determine Physical Activity in COPD Patients in Clinical Practice. / Creación del cuestionario SAQ-COPD (Spanish Physical Activity Questionnaire in COPD) para la medida de la actividad física de pacientes con EPOC en la práctica clínica.

ABSTRACT

INTRODUCTION: Physical activity (PA) is a significant clinical dimension in COPD, but no useful tools are available to determine this variable in routine clinical practice. OBJECTIVE: To create a simple, easy-to-use, specific questionnaire to detect PA deficits. METHOD: A multidisciplinary panel of COPD experts was formed to review PA, its determinants, and measuring methods. The methodology for selecting specific dimensions and items was agreed in rounds, and the aspects to be included in the preliminary version were determined. The questionnaire structure was defined according to applicability of these aspects in clinical practice. Agreements were reached by consensus of the members. RESULTS: A total of 148 items were reviewed, of which only 3 were directly selected. It was decided that the questionnaire should evaluate the intensity (low, moderate, or intense), amount, and frequency of PA, and inactivity or sedentary lifestyles. It also gathers information on the profile of inactive patients, and includes a measure of impact, defined as the patient's perception of their expectations regarding activity, their personal experience, characteristics of their environment, and their personality. The questionnaire is divided into 2blocks, one aimed at quantifying PA, and the other at collecting data for defining the profile and impact in patients with low PA only. CONCLUSION: The SAQ-COPD is a simple, short, specific questionnaire, designed to evaluate PA in COPD patients in clinical practice.
