Some jurisdictions may commit certain types of dangerous sex offenders to state-run detention facilities following the completion of their sentence if that person has a "mental abnormality" or personality disorder that makes the person likely to engage in sexual offenses if not confined in a secure facility.^[1][2] In the United States, twenty states, the federal government, and the District of Columbia have a version of these commitment laws, which are referred to as "Sexually Violent Predator" (SVP) or "Sexually Dangerous Persons" laws.^[2]

Generally speaking, SVP laws have three elements:^[3] that the person has been convicted of a sexually violent offense (a term that is defined applicable statutes), that the person suffers from a mental abnormality and/or personality disorder, which causes their serious difficulty controlling their sexually violent behavior, and that this mental abnormality and/or personality disorder makes the person likely to engage in predatory acts of sexual violence if not confined in a secure facility.

A "mental abnormality" is a legal term that is not identical to a mental disorder, though experts generally refer to diagnoses contained in the Diagnostic and Statistical Manual of Mental Disorders (DSM) as evidence of a mental abnormality.^[4]

In most cases, commitment as an SVP is indefinite; however, once a person is committed, the confining agency is constitutionally required to conduct periodic reviews of that person's mental condition.^{[citation needed]} If the committed person's condition changes so they no longer meets commitment criteria, they must be released. In some circumstances, committed persons can be released to court-monitored conditional releases to less restrictive alternative placements (LRAs).^[5]
