The aim of this longitudinal study was to examine the course of sexualized behavior problems (SBP) over 2 years in a sample comprised of 104 children aged 2-12, including 62 children with histories of child sexual abuse (CSA). Parents completed questionnaires assessing SBP, internalizing and externalizing difficulties at baseline, as well as 2 years later. In more than half (56.7%) of children with clinically significant SBP at baseline, sexualized behaviors persisted and remained at a clinically significant level over time. In children with CSA, 48.4% presented persistent SBP, 27.4% presented transitory SBP, while 19.4% did not present clinically significant SBP at either time. CSA increased the relative risk of persistent SBP 3.29 times, and for each one-unit increase in scores of externalizing difficulties, the odds of persistent SBP increased by 21%. The findings suggest that SBP consequent to CSA, especially when it co-occurs with externalizing difficulties, is likely to remain at levels warranting clinical intervention.
