Illness perceptions and beliefs about medication: impact on health-related quality of life in adolescent kidney transplant recipients.

Adolescents diagnosed with chronic kidney disease (CKD) who undergo kidney transplantation have to adjust to pervasive effects of chronic illness and life-long treatment maintenance, alongside normative developmental stressors. The way in which adolescent transplant recipients experience and think about their illness as well as their medication regimen can be a crucial factor impacting psychosocial outcomes. Participants were 26 adolescent kidney transplant recipients (μ = 16.8 years, σ = 1.69 years) who completed self-report surveys during a clinic visit. Multiple linear regressions were used to investigate whether adolescents' beliefs about medications and attitudes and perceptions of their illness are associated with their overall quality of life. Adolescents' negative illness perceptions contributed to lower transplant-specific health-related quality of life ratings (ΔR2 =.305, p < .01). Additionally, adolescent beliefs about their specific medication regimens (ie, personal medication concerns) (ΔR2 =.342, p < .01), and general beliefs about medication use (ie, harm, overuse) (ΔR2 =.241, p < .05) also contribute significantly to the variance in their overall quality of life ratings. Adolescent transplant patients in older grades and those in special education endorsed lower quality of life. Cognitive components (eg, beliefs, perceptions) of an adolescent kidney transplant recipient's experience contribute to transplant-related quality of life outcomes. This highlights a point of intervention where cognitive change interventions may be utilized and efficacious in improving health outcomes.
