Note. Corrected significance was set p<0.003, due to 16 correlations tested. Generalized linear models with robust standard errors were used, due to heteroscedasticity of some of the measures. The “Drug-Self” condition (our primary condition of interest) refers to perceptions about the need to change one’s own drug use. “Drug-Self > Remaining conditions” refers to the Drug-Self condition minus the mean of the other 3 conditions. The models are defined such that brain activation is used to predict behavior. The asterisk (*) denotes the significant brain-behavior relationship across all participants; the plus sign (+) denotes trends at p<0.05 (uncorrected). Abbreviations: OFC=orbitofrontal cortex, ACC=anterior cingulate cortex.
