If expert opinion testimony based on scientific methods or procedures is offered as evidence in Kansas state courts, the offering party must satisfy the Frye test. See Frye v. United States,
In these proceedings to declare Douglas Girard and Eugene Mallard sexually violent predators, they ask us to instead apply the Daubert test to tire actuarial risk assessments used by the State’s expert witnesses in helping to predict the odds of their reoffending. See Daubert v. Merrell Dow Pharmaceuticals, Inc.,
In both their cases, the district court essentially ruled that Frye applied to the actuarial risk assessments. It admitted the scientific opinion testimony which was partially based on these statistical calculations of risk. The Court of Appeals affirmed, with a majority holding that neither Frye nor Daubert applied because the actuarial assessments were not scientific. In re Girard,
We hold Frye applies and the actuarial risk assessments survive Frye’s scrutiny. The district court therefore is affirmed.
Facts
Girard and Mallard were both convicted of aggravated indecent liberties with a child. The State filed petitions for their continued confinement as sexually violent predators under
The State’s psychologists evaluated both men and opined they met the criteria to be considered sexually violent predators. Their evaluations relied in part on two actuarial risk assessment instruments, the STATIC-99 and the MnSOST-R. The evaluators used these instruments to determine the rate, expressed as a percentage, at which offenders with characteristics similar to Girard and Mai-lard had reoffended. The assessments themselves do not expressly provide a recidivism estimate for the particular offender being evaluated. According to the State’s expert, John Reid, the instrument-based assessments are simply among the factors considered by the evaluators in their sexual predator determinations for the defendants. Other factors include treatment reports, mental health and criminal records, and personal interviews.
In both cases, Reid testified that the actuarial risk assessment instruments, and their use, are generally accepted as reliable widrin die psychological community. In Girard’s hearing, Reid testified that according to a clinical research study, 95.1% of evaluators reported using such instruments “most of die time” or “always.” According to Reid, 73.2% of evaluators rated actuarial assessments as “essential” to an evaluation.
In Mallard’s hearing, Reid testified that the MnSOST is generally accepted in the psychological community and that “[tjhere is lots of literature” that says the MnSOST-R should be used. Mallard’s expert psychologist, Stanley Irving Mintz, countered that actuarial risk assessments are “controversial” because there is “a wide range of differences of opinion” about them. While Mintz testified that he does not use such assessment instruments, he nevertheless conceded that they “are widely used by other psychologists and psychiatrists in mány institutions obviously in Kansas and others” and “are used at Lamed and elsewhere, Canada, so forth.” For Mallard, the district court held that the Frye test applied to the instrument-based assessments. But it also held that they were admissible under either Frye or Daubert.
For Girard, the district court held that the instrument-based assessments were admissible independent of Frye or Daubert because they were not scientific tests but statistical analyses of various factors. In the alternative, the court held the assessments were admissible because Frye applied and they met its requirements.
After the court rejected the defendants’ arguments urging application of the Daubert test to exclude the psychologists’ opinion testimony, it found that Girard and Mallard both met the statutory criteria of a sexually violent predator. Both men were committed to Lamed State Hospital’s Sexually Violent Predator Treatment Program.
After consolidation of the appeals, the Court of Appeals affirmed. The majority held that Frye governs die admissibility of expert scientific opinion in Kansas, and it therefore would “not apply the tests set forth in Daubert until instructed to do so” by the Supreme Court. In re Girard,
Judge Malone concurred. Unlike his colleagues, he believed that opinion testimony based on the instrument-based assessments should be subject to the Frye test. But he agreed with the majority’s result because he concluded that Girard and Mallard
We granted Girard’s and Mallard’s petition for review to address their issue of first impression.
Analysis
Issue: Actuarial risk assessments are subject to Frye.
To establish that an individual is a sexually violent predator under the Kansas Sexually Violent Predator Act, K.S.A. 59-29a01 et seq., the State must prove, among other tilings, that the individual was “convicted of or charged with a sexually violent offense and who suffers from a mental abnormality or personality disorder which makes the person likely to engage in repeated acts of sexual violence.” K.S.A. 59-29a02(a). The narrow issue on appeal concerns the admissibility of the State’s expert witness testimony opining about tiie defendants’ odds of reoffending through use of actuarial risk assessment instruments.
Standard of review
The admission of expert testimony is generally subject to an abuse of discretion standard. Shadden,
Kansas uses the Fiye test
Kansas has “long recognized that the test for the admission of scientific evidence is that applied in Frye v. United States,
In both cases the district court ultimately concluded that the two actuarial risk assessment instruments passed the “general acceptance” standard of Frye. Under the facts of their cases, we agree. The State’s expert testified that the instruments are generally accepted and widely used. Even Mallard’s expert conceded that the instruments are “widely used by other psychologists and psychiatrists in many institutions.” Their testimony is consistent with findings of other state courts. See Roeling v. State,
We also recognize that a number of other state appellate courts have generally concluded that actuarial risk assessments pass the Frye test scrutiny. See Simons, 213 Ill. 2d. at 536 (collecting cases holding that actuarial risk assessments meet tire Frye general acceptance test); In re Commitment of R.S.,
Girard and Mallard correctly concede that the general trend seems to be to uphold admissibility of such evidence under Frye. See also Janus and Prentky, Forensic Use of Actuarial Risk Assessment with Sex Offenders: Accuracy, Admissibility and Accountability, 40 Am. Crim. L. Rev. 1443, 1471, 1497 (2003) (actuarial risk assessments are admissible under either Frye or Daubert). But see Fields,
This is an issue of first impression in Kansas. But we find similarities between actuarial risk assessments and some other types of evidence to which Kansas appellate courts have applied Frye. See, e.g., Kuhn v. Sandoz Pharmaceuticals Corporation,
In Isley, this court rejected defendant’s challenge to the admission of DNA evidence which argued that the derivation of statistical probabilities based upon an expert witness’ chemical analysis did not meet tire Frye test. The court first noted that “DNA testing meets the Frye test in Kansas.”
Similarly, in Smith v. Deppish,
Kansas courts have also applied Frye to blood analysis and accompanying statistical probability testimony. See State v. Washington,
Finally, while using actuarial risk assessment instruments in the area of sexual offender recidivism is not the exact equivalent of testing of DNA and blood, we believe the assessments are nevertheless a science. See Goddard v. State,
“ ‘[T]he STATIC-99 is a risk assessment instrument that combines ten factors. An individual’s scores on these factors are summed, and the total score is compared to a table that shows the reoffense frequencies associated with each score. The table indicates, for example, that a score of 5 is associated with a frequency of sexual recidivism (over a five year follow-up period) of 33%. The highest risk category shown on tire table—scores of 6 or above—is associated with a measured frequency of sexual recidivism (over a 5 year period) of 39%.’ Eric S. Janus, Examining Our Approaches to Sex Offenders ir the Law: Minnesota’s Sex Offender Commitment Program: Would an Empirically-Based Prevention Policy be More Effective, 29 Wm. Mitchell L. Rev. 1083, 1095-96 (2003).”144 S.W. 3d at 850 n.2.
See 40 Am Crim. L. Rev. at 1465, 1471 (referring to actuarial risk assessments as science and “a serious enterprise, backed by sophisticated empirical methodology”).
For all diese reasons, we affirm die district court’s ruling that the actuarial risk
Implicit in our holding is a rejection of Daubert’s application to our facts. In Daubert the United States Supreme Court held that the Frye test of 1923 was superseded by the adoption of the Federal Rules of Evidence in 1972. Daubert v. Merrell Dow Pharmaceuticals, Inc.,
But Kansas has not adopted the Federal Rules of Evidence. And we disagree with Girard and Mallard that the language in our statute regarding expert testimony, K.S.A. 60-456(b), is substantially similar to Rule 702. We also disagree that this statute and the federal rule contain the same intent—which Girard and Mallard do not identify for us. Finally, we observe that Kansas has not adopted Daubert. See, e.g., State v. Heath,
We conclude that in both cases the district court correctly admitted the expert testimony which relied in part upon actuarial risk assessments to opine Girard and Mallard were sexually violent predators.
The judgment of the Court of Appeals affirming the district court is affirmed. The judgment of the district court is affirmed.
