- •There is evidence of stark disparities in cancer pain outcomes among African Americans (AAs).
- •Differential analgesic adherence may be an important explanatory variable in these disparities.
- •We objectively assessed adherence to prescribed analgesics for cancer pain among AAs and whites.
- •Both magnitude and predictors of adherence varied by race indicating unique intervention targets for AA and whites.
- •Commonly implicated fears (eg, addiction concerns) did not explain adherence in both groups.
- •EP presents a biology of pain that underpins a biopsychosocial approach.
