Fleisher et al. (2016) created an instrument eliciting medication beliefs of persons with PD; identified demographic and clinical characteristics associated with beliefs; and examined whether beliefs are associated with dopaminergic therapy adherence. Negative beliefs about PD treatments are associated with lower quality of life and may be related to medication non-adherence. Further study of any causal relationship between beliefs and medication non-adherence in PD will inform the design of future patient-centered interventions to improve adherence.
