Specific aims of this research are to a) examine the long-term effects of prenatal anxiety on dimensional and diagnostic measures of psychopathology in early adolescence; b) assess the role of the HPA axis underlying the links between prenatal anxiety on adolescent psychopathology and stress vulnerability; c) test competing hypotheses concerning the processes by which prenatal anxiety has direct, mediated or moderated effects on adolescent psychopathology; and d) test the hypothesis that the effects of prenatal anxiety/stress on behavioral/emotional problems in early adolescence are moderated by genetic risk.
