Objective:
This study aimed to identify psychosocial predictors of two-year antiepileptic drug (AED) adherence trajectories among youth with newly diagnosed epilepsy, controlling for known demographic and medical factors.
Method:
This study is part of a large, prospective, longitudinal observational study of AED adherence and medical outcomes in youth with newly diagnosed epilepsy. Parents completed questionnaires of psychosocial and family functioning at one month and one year following diagnosis. Chart review and questionnaires were used to collect medical variables and seizure outcomes. Previously established two-year AED adherence trajectories (Severe Early Nonadherence, Variable Nonadherence, Moderate Nonadherence, High Adherence) were used as the outcome variable.
Results:
Participants were 91 parents of youth with epilepsy (7.3±2.8years of age; 60% male) and their families. Early (one month following diagnosis) predictors of two-year adherence trajectories included socioeconomic status, epilepsy knowledge, family problem-solving, and family communication. Significant predictors one year following diagnosis included socioeconomic status, parent fears and concerns, and parent life stress.
Conclusion:
There are modifiable parent and family variables that predict two-year adherence trajectories above and beyond known medical (e.g., seizures, side effects) factors. Psychosocial interventions delivered at key points during the course of epilepsy treatment could have a positive impact on adherence outcomes.
