The RewP has been shown to increase across adolescence; however, most studies have examined the RewP across two assessments, and no studies have examined within-person changes across adolescence into young adulthood. Moreover, the RewP has been identified as a neurobiological risk factor for adolescent-onset depression, but it is unclear whether childhood psychosocial risk factors might predict RewP development across adolescence. In a sample of 317 8- to 14-year-old girls (Mage = 12.4, SD = 1.8), the present study examined self-report measures of depression symptoms and stressful life events at baseline and the ?RewP during the doors guessing task across three timepoints. Growth modeling indicated that, across all participants, the ?RewP did not demonstrate linear change across adolescence. However, baseline anhedonia symptoms predicted within-person changes in the ?RewP, such that individuals with low anhedonia symptoms demonstrated a linear increase in the ?RewP, but individuals with high anhedonia symptoms had no change in the ?RewP across adolescence. Similar patterns were observed for stressful life events. The present study suggests that childhood risk factors impact the development of reward-related brain activity, which might subsequently increase risk for psychopathology.
