Abstract
This study investigated the effects of illness perceptions and coping with disease on health-related quality of life in chronic obstructive pulmonary disease. Therefore, participants (N = 444) completed online questionnaires assessing illness severity (chronic obstructive pulmonary disease stage), Illness Perceptions Questionnaire, coping with disease (Essener Coping Questionnaire), and health-related quality of life (short form-12). Hierarchical regression and moderation analyses were conducted. The results showed that health-related quality of life was predicted by illness perceptions and several aspects of coping with disease. The association between illness perceptions and health-related quality of life was mediated by the corresponding coping with disease subscales. It is concluded that in order to prevent decreasing health-related quality of life in chronic obstructive pulmonary disease, treatment may be adjusted by promoting coping with disease and functional illness perceptions.
