Considering the role of reward sensitivity in the relationship between early adversity and sexual behaviour

Many individuals in the United States will experience some form of abuse or neglect before the age of 18. Exposure to such adversities earlier in life can predict greater sexual risk engagement such as high sexual partner number. While the research examining the influence of early adversity on sexual behaviour is vast, we have yet to fully understand why this association exists. In the present manuscript we attempt to shed light on potential predictors and moderators of this association and offer suggestions for future research. Specifically, we begin with a brief review of the existing research pertaining to early adversity and sexual risk taking. Then, we outline potentially important moderators to consider such as impulsivity, sensation seeking, and reward sensitivity.
