Kosse RC, et al. - Using baseline data from asthmatic adolescents who participated in the ADolescent Adherence Patient Tool study, researchers focused on the link between illness perceptions, medication beliefs, medication adherence, disease control, and quality of life (QoL) in adolescents with asthma in this cross-sectional study. They analyzed 243 participants with age 15.1 ± 2.0 years and 53% were females. Non-adherence (Medication Adherence Report Scale ≤23) was reported in more than half of these adolescents (62%; n = 151) and uncontrolled asthma was present in 77% (n = 188). Findings revealed a strong positive correlation between disease control and QoL. Correlation of all illness perceptions items with disease control and QoL was evident; ‘identity’ (symptom perception) and QoL correlated most strongly. They found a correlation between medication adherence and medication beliefs, disease control, and QoL, whereas medication beliefs were only related to adherence. They concluded that improved adherence, and therefore, improved disease control and better QoL, might be achieved by stimulating positive illness perceptions and medication beliefs.
