Abstract
Objective: Asthma control and quality of life (QoL) are important disease outcomes for asthma patients. Illness perceptions (cognitive and emotional representations of the illness) and medication beliefs have been found to be important determinants of medication adherence, and subsequently disease control and QoL in adults with asthma. In adolescents, this issue needs further elucidation. Therefore, the aim of this study was to explore the relationship between illness perceptions, medication beliefs, medication adherence, disease control, and QoL in adolescents with asthma.
Methods: In this cross-sectional study, we used baseline data of adolescents with asthma (age 12–18 years) who participated in the ADolescent Adherence Patient Tool (ADAPT) study. Questionnaires were administrated online, and included sociodemographic variables and validated questionnaires measuring self-reported illness perceptions, medication beliefs, medication adherence, disease control, and QoL.
Results: Data of 243 adolescents with asthma were available; age 15.1 ± 2.0 years and 53% females. More than half of these adolescents (62%; n = 151) reported to be non-adherent (Medication Adherence Report Scale ≤23) and 77% (n = 188) had uncontrolled asthma. There was a strong positive correlation between disease control and QoL (r = 0.74). All illness perceptions items were correlated with disease control and QoL, with the strongest correlation between ‘identity’ (symptom perception) and QoL (r=–0.66). Medication adherence was correlated to medication beliefs (r = 0.38), disease control (r = 0.23), and QoL (r = 0.14), whereas medication beliefs were only associated with adherence.
Conclusions: Stimulating positive illness perceptions and medication beliefs might improve adherence, which in turn might lead to improved disease control and better QoL.
