ΔBPND ventral striatum dopamine release capacity (%), CTQ Childhood Trauma Questionnaire, GLM general linear model
The general linear model including dexamphetamine-induced positive psychotic symptoms as dependent variable was superior to the null-model in predicting symptom scores and providing evidence that the interaction between childhood trauma and mesolimbic dopamine sensitivity (interaction term: ΔBPND × CTQ score) was a predictor of dexamphetamine-induced positive psychotic symptoms
