- Abstract
<bold>Objective: </bold>To investigate longitudinal associations of health beliefs, which included self-efficacy, outcome expectancies, and perceived barriers, and demographic risk factors (i.e., age, gender, race, and family income) with antihypertensive medication adherence in adolescents with chronic kidney disease (CKD) over 24 months.<bold>Method: </bold>The sample included 114 adolescents (M age = 15.03 years, SD = 2.44) diagnosed with CKD. Adolescents reported their self-efficacy for taking medications, medication outcome expectancies, and barriers to adherence at baseline and 12 and 24 months after baseline. Antihypertensive medication adherence was assessed via electronic monitoring for 2 weeks at baseline and 6, 12, 18, and 24 months after baseline.<bold>Results: </bold>Adherence increased and then decreased over the 2-year study period (inverted U-shape). Self-efficacy, outcome expectancies, and barriers did not change over time. Older adolescent age, female gender, African American race, <$50,000 annual family income, and public health insurance were associated with lower adherence. However, family income was the primary demographic risk factor that predicted adherence over time (≥$50,000 annual family income was longitudinally associated with higher adherence). Higher self-efficacy and more positive and less negative outcome expectancies across time were also associated with higher antihypertensive medication adherence across time.<bold>Conclusions: </bold>Clinical interventions should be developed to target medication self-efficacy and outcome expectancies to improve long-term antihypertensive medication adherence in adolescents with CKD. Family income may be considered when conceptualizing contextual factors that likely contribute to adolescents' consistent challenges with medication adherence over time.
