We have tracked research presentations at the UR symposium, authorship of an honors thesis, or attainment of the CURO scholar distinction, which is a permanent transcript notation for students who complete two directed-research courses, present at the UR symposium, and submit an honors thesis (Table 1).
Although large, these estimates likely represent an underestimate of the true burden of child maltreatment due to the lack of accurate incidence reporting and the inability to assess costs for indirect effects of child maltreatment on temporary or permanent physical and cognitive disabilities, and sustained losses in future education and occupational attainment[ 3].
