To obtain prevalence estimates for incest, it seems reasonable to use the general prevalence estimates for sexual abuse combined with the following rate estimates for the type of relationship:
Prevalence Rate Estimates of Type of Relationship Between CSA Respondents and Partners/Abusers in College and National Populations
|Wider Family CSA||Close Family CSA|
Note. Close family CSA includes sexual relations with very
close relatives (e.g., biological or step parents, grandparents, older
siblings). Wider family CSA includes both close family CSA and
relations with other relatives. Prevalence rate estimates are
weighted means of prevalences from individual samples. College
estimates come from studies included in the current review; national
estimates come from 3 studies of national samples
(Baker & Duncan, 1985;
Laumann et al., 1994;
Lopéz et al., 1995).
a Based on 21, 9, and 33 samples for females, males, and combined, respectively.
b Based on 3, 3, and 6 samples for females, males, and combined, respectively.
c Based on 10, 6, and 19 samples for females, males, and combined, respectively.
