A causal model of asthma control in adults in adults with asthma
Abstract:
Asthma control is the goal of asthma management to prevent
exacerbations and minimize morbidity. Currently was reported poor control and not
achieved asthma management goal. The purpose of this study was to develop and test
a causal model of asthma control among adults with asthma. A sample of 336
participants was recruited from asthma and COPD clinics in tertiary hospitals in
eastern Thailand. Data were collected by self-administered questionnaires including
the Demographic data form, the Brief illness perception questionnaire, the Depression
subscale of Hospital Anxiety and depression Scale, the Job Stress Scale, the
Functional, Communicative, and Critical Health Literacy Scale, the Self-efficacy
subscale of the Knowledge, Attitude, and Self-efficacy Asthma Questionnaire, the
multidimensional scale of perceived social support, the Asthma Self-Management
Behavior Instrument, and The asthma control questionnaire. AMOS software program
was used to test the model of asthma control.
The results showed that the final model of asthma control consisted of
illness perception, depression, job stress, health literacy, asthma self-efficacy, social
support, and asthma self-management behaviors, which explained 54% of the total
variance for asthma control (R
2=.54). Asthma self-management behaviors and job
stress had a direct effect on asthma control, whereas asthma self-efficacy, social
support, and asthma self-management behaviors were a moderator between illness
perception, depression, job stress, health literacy, and asthma control. These findings
suggest that nurses should develop nursing interventions to improve asthma control
by reducing depression and job stress and promoting illness perception, health
literacy, asthma self-efficacy, social support, and asthma self-management behaviors.
