Kosse RC, Koster ES, Kaptein AA, et al. - Researchers undertook this cross-sectional analysis to investigate the link between illness perceptions, medication beliefs, medication adherence, disease control, and quality of life (QoL) among adolescents suffering from asthma. For this purpose, baseline data for adolescents with asthma (age 12–18 years) who engaged in the ADolescent Adherence Patient Tool study were analyzed. A strong positive correlation between disease control and QoL was identified. Experts also found correlation of all illness perceptions items with disease control and QoL, with the strongest link between ‘identity’ (symptom perception) and QoL. A correlation of medication adherence with medication beliefs, disease control, and QoL was evident, whereas medication beliefs were only related to adherence. Overall, it was concluded that adherence might be improved via stimulating positive illness perceptions and medication beliefs, which in turn might result in improved disease control and improved QoL.
