We have no doubt that a testifying psychologist or psychiatrist may refer to actuarial risk assessment instruments used in the formation of the expert’s opinion. As the Appellate Division noted in applying the standard set forth in
Frye v. United States,
293
F.
1013, 1014 (D.C.Cir.1923), the use of actuarial instruments in the assessment process has gained general acceptance.

Although there are critics who challenge the validity and predictability of actuarial instruments in sex offender assessments, the record expert testimony and scientific literature demonstrates that clinicians specializing in sex offender assessments generally support the use of actuarial instruments in the overall assessment process even though they do not support reliance on the actuarial instruments alone.

The extensive expert testimony in this matter concerning validation studies, cross-validation studies, reliability studies, correlation coefficients, and clinically-derived factors attests to ... reliability in this context, where the actuaríais are not used as the sole or free-standing determinants for civil commitment. They are not litmus tests. There is no requirement that the actuarial instruments be the best methods *137 which could ever be devised to determine risk of recidivism. What is required is that they produce results which are reasonably reliable for their intended purpose.
[Id. at 539,773 A.2d 72 (citation omitted).]
We conclude, as did the courts below, that actuarial risk assessment instruments may be admissible in evidence in a civil commitment proceeding under the SVPA when such tools are used in the formation of the basis for a testifying expert’s opinion concerning the future dangerousness of a sex offender. The testifying expert shall be permitted to refer to such instruments in explaining how he or she reached a conclusion concerning an individual’s risk assessment. In so holding, we acknowledge that a testifying expert now may rely on actuarial as well as clinical information when formulating an opinion concerning future dangerousness. We anticipate that the trial court will regard the actuarial assessment information, as did Judge Freedman below, as simply a factor to consider, weigh, or even reject, when engaging in the necessary factfinding under the SVPA.
