title: Self-regulation predictors of medication adherence among ethnically different pediatric patients with renal transplants.
abstract: OBJECTIVE
  To predict medication adherence among ethnically different pediatric patients with renal transplants between the ages of 6 and 20 years old, using self-regulation variables including motivation, perceived control and responsibility, and perceived support.
  
  
  METHODS
  Twenty-six African American children and 42 Caucasian children were verbally administered the Self-Regulation of Medication Adherence Battery to assess their (1) motivation to be medication adherent, (2) perceived control of and responsibility for medication adherence, and (3) perceived support of medication adherence from their primary caregiver. Four measures were used to assess medication adherence: self-ratings, nephrologists' ratings, cyclosporine levels, and pill count/refill histories.
  
  
  RESULTS
  For the African American patients, regression analyses revealed that responses to motivation and perceived control questions that focused on self-efficacy were unique predictors of medication adherence as rated by their primary nephrologist. For the Caucasian patients, one motivation question regarding how often they forget to take their medication predicted their self-reported adherence.
  
  
  CONCLUSIONS
  Facilitating their beliefs that they can regularly take their medications may help promote medication adherence among African American children with renal transplants, whereas for Caucasian children, providing cues and reminders to take their medications may help. We discuss implications of the results for multimodal assessment of medication adherence and for ethnic group-specific medication adherence research and interventions.
