Making the scale for the compliance of patients with chronic obstructive pulmonary disease during home oxygen therapy

Abstract

Objective To make the scale for the compliance of patients with chronic obstructive pulmonary disease (COPD) during home oxygen therapy. Methods By literature searching, semi-structured interview, expert consultation, as well as pre test, the tentative scale was formed at first. Then the investigation was conducted among 324 patients with COPD selected. Finally the scale was formed by testing the reliability and validity. Results The scale was made up of two dimensions with 16 items in total. It showed that Cronbach α coefficient was 0.984, split-half reliability was 0.976, and content validity index was 0.98. The exploratory factor analysis combined with AMOS 7.0 confirmatory factor analysis was used for construct validity of the home oxygen therapy compliance scale. Conclusions The self-management behavior scale for patients with COPD shows good reliability and validity, which can be used to evaluate the compliance during home oxygen therapy and provide reference tool for COPD patients' family intervention.
