Abstract
There is much concern about the likelihood that online sexual offenders particularly online child pornography offenders) have either committed or will commit offline sexual offenses involving contact with a victim. This study addresses this question in two metaanalyses:
[1] the first examined the contact sexual offense histories of online offenders,
whereas
[2] the second examined the recidivism rates from follow-up studies of online
offenders.
[1] The first meta-analysis found that approximately 1 in 8 online offenders (12%)
have an officially known contact sexual offense history at the time of their index offense (k = 21, N = 4,464). Approximately one in two (55%) online offenders admitted to a contact sexual offense in the six studies that had self-report data (N = 523).
[2] The second meta-analysis revealed that 4.6% of online offenders committed a new sexual offense of some kind during a 1.5- to 6-year follow-up (k = 9, N = 2,630); 2.0% committed a contact sexual offense and 3.4% committed a new child pornography offense.
The results of these two quantitative reviews suggest that there may be a distinct subgroup of online-only offenders who pose relatively low risk of committing
contact sexual offenses in the future.

Research conducted during the 1970s, 1980s, and 1990s consistently reported widely accepted negative outcomes associated with child sexual abuse. 
In 1998, Rind, Tromovitch, and Bauserman conducted a meta-analysis challenging the four most often reported correlates of child sexual abuse. 
The present study attempted to reexamine the four main objectives of the Rind et al. (1998) study, correcting for methodological and statistical problems identified by Dallam et al. (2001) and Ondersma et al. (2001). 
The current meta-analysis supported the findings by Rind et al. (1998) in that child sexual abuse was found to account for 1% of the variance in later psychological outcomes, whereas family environment accounted for 5.9% of the variance. 
In addition, the current meta-analysis supported the finding that there was a gender difference in the experience of the child sexual abuse, such that females reported more negative immediate effects, current feelings, and self-reported effects. 
The implications of these findings, problems with replicating the Rind et al. (1998) meta-analysis, and future directions are discussed.
