Description
Summary:Adolescents with asthma often report poor medication adherence and asthma control. Cognitive factors embedded in the social cognitive theory including self-efficacy, outcome expectations, and barrier perceptions may explain poor asthma outcomes in this population. This study was performed to examine the extent to which these cognitive factors are intercorrelated and explain medication adherence and asthma control in urban adolescents. A total of 373 urban adolescents (12-20 years) with asthma completed questionnaires measuring asthma-related self-efficacy, outcome expectations, barrier perceptions, medication adherence, and asthma control. Multiple linear regression was conducted to examine the extent to which the three cognitive factors predicted medication adherence and asthma control after controlling for covariates including age, sex, household income, and age at diagnosis. Participants' ages were on average 14.68 (±1.94) years; 50% were female, and most (78.6%) were African American. Higher self-efficacy associated with lower barrier perceptions and higher outcome expectations ( =0.50,
