Abstract

Adolescents with asthma endorse psychosocial difficulties as barriers to inhaled corticosteroid adherence. This study examined patterns of variability in adherence and within-person associations of psychosocial variables with adherence across days. Participants included twenty-five adolescents (Mage = 14.7, SD = 1.68; 48% male) with persistent asthma. We measured adherence via electronic monitoring. Adolescents completed daily surveys measuring asthma symptoms, stress, mood, and affect. We examined within-person differences in the effect of symptoms and psychosocial variables on adherence. Adherence decreased over time. The addition of a random slope improved model fit (− 2ΔLL(1) = 9.36, p < .01). Greater asthma symptoms were significantly associated with higher adherence at the within-person level and with lower adherence between persons. We observed evidence of individual differences in the associations of stress and affect with adherence. Within-person, day-level fluctuations in adherence occur. Symptoms and psychosocial variables may influence adherence. Individually tailored interventions may effectively address nonadherence.
