Influencing factors of self-efficacy among community-based patients with chronic obstructive pulmonary disease

Abstract

Objective To investigate the self-efficacy levels and its influencing factors of community-based patients with chronic obstructive pulmonary diseases (COPD).Methods From October 2008 to March 2009,320 community COPD patients were recruited from a Shanghai community.They undertook questionnaires,scale survey and pulmonary function testing so as to investigate the influencing factors of self-efficacy.Results The total scale of self-efficacy was 74.24 ± 9.50 and the level of selfefficacy in 286 cases( 89.4％ )was intermediate.The knowledge of COPD,social supports,forced expiratory volume at 1 second (FEV1)/forced vital capacity (FVC) and self-management level were entered into regression equation and could explain 57.1％ of the total variance of independent variables.Conclusions The knowledge of COPD,social supports,FEV1/FVC and self-management level are the major influencing factors of self-efficacy in the COPD patients.We should improve the knowledge of disease and strengthen the psychological care and social supports so as to improve their quality of life.
