Abstract
Asthma is a heterogeneous disease and chronic inflammation of the respiratory tract that has an impact on the decreased quality of life. The design of this research is non-experimental cross-sectional. The variables of this study are illness perception, control of asthma, lung function values, and life quality of asthma patients. The relationship of asthma control, illness perception, lung function value, and life quality of asthma patients can be seen with structural equation modeling using Smart-PLS software. The results are only control of asthma affects life quality, where the coefficient value is 0.511, which is positive and significant (p = 0,000). Lung function value and asthma quality indicate that lung function has a positive relationship direction seen from the coefficient value of 0.306 but not significant (p = 0.061). The correlation between illness perception and life quality of asthma was negative, where the coefficient value was - 0.142 and not significantly different (p = 0.332). This means that the direction of the relationship is reversed; it means the quality of life of asthmatic patients, which affects illness perception by 14.2%. The conclusion is that the life quality of asthmatic patients is influenced by the control of asthma and lung function. But it’s different from illness perception, where there is a negative relationship between illness perception and life quality of asthma patients. Which means illness perception affects the life quality of asthma patients.
Highlights
Asthma is a chronic inflammatory disease of the respiratory tract with symptoms of coughing, tightness in the chest, and episodic wheezing due to airway obstruction
In a previous study conducted by Imelda et al (2007) using Asthma quality of life questionnaire (AQLQ) on 130 patients of mild, moderate, and severe chronic asthma showed asthma category affects life quality in patients with a moderate level of asthma compared to mild level while life quality is not affected by severe asthma patients compared to moderate degrees
This research variable is disease perception assessed by the IPQ questionnaire, asthma control determined by the ACT questionnaire, pulmonary function values assessed by peak flow meter values, and quality of life scores for asthma patients as measured by the AQLQ questionnaire
Summary
Asthma is a chronic inflammatory disease of the respiratory tract with symptoms of coughing, tightness in the chest, and episodic wheezing due to airway obstruction. This results in decreased quality of life, decreased productivity, absenteeism in schools, increased health costs, the risk of hospitalization, and even death (Ministry of Health, 2008). Similar research is needed to determine the profile of perceptions of asthma outpatient (chronic asthma) with different backgrounds, namely in community areas (pharmacies) because patients in community areas tend to seek treatment at different doctors. Life-related to health is a subjective experience for each patient This depends on the impact of the disease and its management on life quality. In a previous study conducted by Imelda et al (2007) using AQLQ on 130 patients of mild, moderate, and severe chronic asthma showed asthma category affects life quality in patients with a moderate level of asthma compared to mild level while life quality is not affected by severe asthma patients compared to moderate degrees
