RECRUITMENT, ASTHMA
There were some limitations in this study. First, there were only two clinics for treatment of adolescents with asthma which we could recruit participants and made fewer samples available for inclusion in the study. Second, patients who were not willing to participate in the study were likely to have low adherence, and this may have led to conduct a study on patients with better adherence. Third, the control group used in this study was standard of care. While a more rigorous control group would have been an attention control group, this was not feasible given the recruitment strategy. Finally, in this study the sample size was small and the treatment effects were only studied at immediate post‐test and 3 months later (the goal was to test the short‐term impact of the intervention). So, it is recommended that the intervention be performed with a larger sample size and longer follow‐up time.
