Importance  Psychotic disorders are characterized by attenuated activity in the brain’s valuation system in key reward processing areas, such as the ventral striatum (VS), as measured with functional magnetic resonance imaging.

Objective  To examine whether common risk variants for psychosis are associated with individual variation in the VS.

Design, Setting, and Participants  A cross-sectional study of a large cohort of adolescents from the IMAGEN study (a European multicenter study of reinforcement sensitivity in adolescents) was performed from March 1, 2008, through December 31, 2011. Data analysis was conducted from October 1, 2015, to January 9, 2016. Polygenic risk profile scores (RPSs) for psychosis were generated for 1841 healthy adolescents. Sample size and characteristics varied across regression analyses, depending on mutual information available (N = 1524-1836).

Main Outcomes and Measures  Reward-related brain function was assessed with blood oxygen level dependency (BOLD) in the VS using the monetary incentive delay (MID) task, distinguishing reward anticipation and receipt. Behavioral impulsivity, IQ, MID task performance, and VS BOLD were regressed against psychosis RPS at 4 progressive P thresholds (P < .01, P < .05, P < .10, and P < .50 for RPS models 1-4, respectively).

Results  In a sample of 1841 healthy adolescents (mean age, 14.5 years; 906 boys and 935 girls), we replicated an association between increasing psychosis RPS and reduced IQ (matrix reasoning: corrected P = .003 for RPS model 2, 0.4% variance explained), supporting the validity of the psychosis RPS models. We also found a nominally significant association between increased psychosis RPS and reduced MID task performance (uncorrected P = .03 for RPS model 4, 0.2% variance explained). Our main finding was a positive association between psychosis RPS and VS BOLD during reward anticipation at all 4 psychosis RPS models and for 2 P thresholds for reward receipt (RPS models 1 and 3), correcting for the familywise error rate (0.8%-1.9% variance explained).

Conclusions and Relevance  These findings support an association between psychosis RPS and VS BOLD in adolescents. Genetic risk for psychosis may shape an individual’s response to rewarding stimuli.

Positive associations between the psychosis risk profile score (RPS) and blood oxygen level dependency (BOLD) in the ventral striatum (VS) during reward anticipation and reward receipt at 4 progressive P thresholds (P < .01 for RPS model 1, P < .05 for RPS model 2, P < .10 for RPS model 3, and P < .50 for RPS model 4), controlling for age, sex, testing site, Wechsler Intelligence Scale for Children–Fourth Edition variables, and the first 5 principal components (n = 1528 and 1559, respectively). All clusters are corrected for the familywise error across the bilateral VS (P < .05). Plots on the right show the mean psychosis RPSs across 10 deciles plotted against BOLD parameter estimates in the significant clusters identified in the multiple regression. Note that the 10 deciles reflect the data extracted from the clusters within the VS, which remained significant and are purely for illustration purposes. Error bars indicate 95% CI. AU indicates arbitrary units; L, left hemisphere; NS, nonsignificant.
