OPINION
¶ 1 Based on application of due process principles enunciated by the United States Supreme Court, we uphold the constitutionality of Arizona’s Sexually Violent Persons Act (“Act”). However, we vacate the finding that Appellant Wilber W. is a sexually violent person (“SVP”), and we remand for further proceedings consistent with this decision.
¶ 2 Wilber appeals from an order committing him to the Arizona Community Protection and Treatment Center as an SVP following a jury trial conducted pursuant to the Act.
See
Ariz.Rev.Stat. (“A.R.S.”) §§ 36-3701 through — 3717 (Supp.2001). Originally, Wil-ber raised several evidentiary issues on appeal. After briefing of those issues, the United States Supreme Court decided the case of
Kansas v. Crane,
¶ 3 Wilber now argues that the Act is unconstitutional and violates the due process rights of persons committed thereunder by not requiring a finding of serious difficulty in controlling behavior, in accordance with
Crane.
He also contends that he was improperly found to be an SVP because the trial court failed to give a jury instruction defining “likely” in A.R.S. § 36-3701(7)(b) to mean “highly probable” that he would “engage in acts of sexual violence.” The State relies on the Arizona Supreme Court case of
In re Leon G.,
¶ 4 The day before oral argument in this court, the United States Supreme Court granted certiorari in
Leon G.,
vacated our supreme court’s decision, and remanded that case for reconsideration in light of
Crane. See Glick v. Arizona,
¶ 5 We hold that Arizona’s Sexually Violent Persons Act allows civil commitment of a person only if a jury finds beyond a reasonable doubt that the person:
1. has a “mental disorder” as defined in A.R.S. § 36-3701(5);
2. is a “sexually violent person” as defined in A.R.S. § 36-3701(7) with the term “likely” explained as meaning “highly probable”; and
3. has serious difficulty controlling his or her behavior.
Because there was no specific finding at Wil-ber’s commitment hearing that he has serious difficulty controlling his behavior, we vacate the commitment order and remand for further proceedings.
CONSTITUTIONAL ANALYSIS
¶ 6 In
Kansas v. Hendricks,
¶ 7 Last year, one panel of this court and the Arizona Supreme Court reached different conclusions regarding the interpretation of
Hendricks.
This court concluded that
Hendricks
required a finding of volitional incapacity and that the Act was unconstitutional because it did not contain such a requirement.
In re Leon G.,
¶ 8 An SVP is defined in the Act as:
a person to whom both of the following apply:
(a) Has ever been convicted of or found guilty but insane of a sexually violent offense or was charged with a sexually violent offense and was determined incompetent to stand trial.
(b) Has a mental disorder that makes the person likely to engage in acts of sexual violence.
A.R.S. § 36-3701(7). A “mental disorder” means a:
paraphilia, personality disorder or conduct disorder or any combination of paraphilia, personality disorder and conduct disorder that predisposes a person to commit sexual acts to such a degree as to render the person a danger to the health and safety of others.
A.R.S. § 36-3701(5). Our supreme court concluded that it was not constitutionally necessary to find volitional incapacity as a separate element under the Act.
Leon G.,
We think the [Hendricks ] Court’s explanation makes clear its view that requiring that dangerousness be linked with or caused by an additional factor, such as *304 mental illness or abnormality, satisfies the notion that some “volitional impairment” must render those who fit within the subclass subject to confinement dangerous “beyond their control.” That is, if the state establishes not only that a person is dangerous, but also that a mental illness or abnormality caused the dangerousness, the state has met its burden to show a lack of control.
Id.
at 302, ¶ 12,
¶ 9 After
Leon G.,
the United States Supreme Court in the recent case of
Kansas v. Crane,
¶ 10 The United States Supreme Court agreed with the State of Kansas that Hendricks does not mandate a finding of total inability to control behavior. However, the Supreme Court stressed that there must be proof of serious difficulty in controlling behavior:
[In Hendricks,] we did not give to the phrase “lack of control” a particularly narrow or technical meaning. And we recognize that in cases where lack of control is at issue, “inability to control behavior” will not be demonstrable with mathematical precision. It is enough to say that there must be proof of serious difficulty in controlling behavior. And this, when viewed in light of such features of the case as the nature of the psychiatric diagnosis, and the severity of the mental abnormality itself, must be sufficient to distinguish the dangerous sexual offender whose serious mental illness, abnormality, or disorder subjects him to civil commitment from the dangerous but typical recidivist convicted in an ordinary criminal case.
Id. at 870 (emphasis added).
¶ 11 The State contended at oral argument in this appeal that our supreme court opinion in
Leon G.
controls the resolution of this case. We disagree because the United States Supreme Court has vacated that decision.
Glick,
THE ARIZONA ACT IS CONSTITUTIONAL
¶ 12 After
Hendricks,
it was clear that due process required at least two findings to be made before a sex offender could be committed under a civil commitment statute: a finding of dangerousness linked with the existence of a mental abnormality or personality disorder.
¶ 13 Does due process, according to
Hendricks,
also require an additional finding of volitional incapacity? Prior to
Crane,
various courts reached different conclusions from
Hendricks.
The Kansas Supreme Court read
Hendricks
as requiring proof of
total
volitional impairment.
In re Crane,
¶ 14 The United States Supreme Court in
Crane
has now clarified that due process does not require total volitional incapacity.
See
¶ 15 Based on Crane, it is not enough that Arizona’s Act requires a finding of dangerousness linked with the existence of a mental disorder. To pass constitutional muster, the Act must also require proof of serious difficulty controlling behavior. We conclude that it does.
¶ 16 We must presume statutes are constitutional and, if possible, construe them so as to avoid rendering them unconstitutional, resolving any doubts in favor of their constitutionality.
Bills v. Arizona Prop. & Cas. Ins. Guar. Fund,
¶ 17 The language of the Act does not use the language found in
Crane
regarding the requirement of serious difficulty in controlling behavior. Due process does not require, however, that state legislatures use particular language in defining mental disorders.
Crane,
¶ 18 The Act defines an SVP as a person with a “mental disorder” that
“makes
the person likely to engage in acts of sexual violence.” A.R.S. § 36-3701(7) (emphasis added). A disorder that “makes” a person likely to engage in sexual violence is a disorder that impairs or tends to overpower the person’s ability to control his or her behavior. Furthermore, the Act defines the phrase “mental disorder” as a disorder that “predisposes” a person to “commit sexual acts to such a degree as to render the person a danger to the health and safety of others.” A.R.S. § 36-3701(5). A person who has a mental disorder that
predisposes
the person to commit sexual acts that are dangerous to others and that
makes
the person likely to engage in sexual violence is a person who has serious difficulty in controlling his or her behavior.
3
Because we conclude that the language of Arizona’s Act implicitly requires a finding of serious difficulty in controlling behavior, we hold that the Act is constitutional.
See In re Commitment of Laxton,
¶ 19 Our approach parallels that taken in both
Hendricks
and
Crane.
The United States Supreme Court in
Hendricks
upheld the constitutionality of the Kansas SVP act, even though its language did not specifically require a finding of serious difficulty in controlling behavior.
SPECIFIC JURY INSTRUCTION ON SERIOUS DIFFICULTY CONTROLLING BEHAVIOR
¶ 20 The essence of Crane is that due process does not permit a person to be deprived of liberty without a finding of serious difficulty in controlling behavior. Accordingly, we further hold that juries in commitment hearings under the Act must, to comply with due process, be specifically instructed on the requirement of finding serious difficulty in controlling behavior.
¶ 21 We recognize that some courts in other jurisdictions have declined, after
Crane,
to require a jury instruction specifically directing jurors to make such a finding.
See Laxton,
“Although the words of [Wisconsin’s SVP statute] might be interpreted by lawyers and judges to include a link between the mental disorder and a serious difficulty in controlling behavior, the jury instructions based directly on the language of [Wisconsin’s SVP statute] do not set forth this link for non-lawyers.” Laxton,647 N.W.2d at 798, ¶ 45 (Abrahamson, C.J., dissenting).
Therefore, at civil commitment hearings under the Act, the jury should be instructed that a “mental disorder” means:
a paraphilia, personality disorder or conduct disorder or any combination of para-philia, personality disorder and conduct disorder that (1) predisposes a person to commit sexual acts to such a degree as to render the person a danger to the health and safety of others and (2) causes the person to have serious difficulty in controlling his or her behavior.
See Thomas,
¶ 22 The record before us reveals that the jury was not instructed to determine if Wilber has serious difficulty controlling his behavior, and we cannot conclude as a matter of law that the evidence demonstrated that Wilber does in fact have serious difficulty controlling his behavior. 5 Accordingly, we vacate the commitment order and remand for a new commitment hearing with the jury to *307 be instructed in accordance with this decision.
DEFINITION OF THE TERM “LIKELY”
¶ 23 Our supreme court in
Leon G.
held that “likely” in A.R.S. § 36-3701(7)(b) of the Act means “highly probable” and that juries should be so instructed.
¶ 24 Under the Act, an SVP means a person who “[h]as a mental disorder that makes the person likely to engage in acts of sexual violence.” A.R.S. § 36-3701(7)(b)(emphasis added). The term “likely” is undefined in the Act. We agree with our supreme court’s reasoning in Leon G. that “likely” as used in the Act means “highly probable”:
In this instance, after considering other statutory language, we conclude that the legislature’s use of the term “likely” reflects its decision to require a standard somewhat higher than “probable.” Dietz v. Gen. Elec. Co.,169 Ariz. 505 , 510,821 P.2d 166 , 171 (1991) (when the meaning of a statutory term is not clear, we look to the overall language of the statute for assistance). The legislature provided guidance as to the meaning of “likely” in section 10 of the [Act], which sets out the legislative findings that led to passage of the act. Ariz. Sess. Laws 1995, Ch. 257, § 10. Subsection 3 directly addresses the civil commitment procedure adopted as part of the act. In that subsection, the legislature notes that, for a “small but extremely dangerous group of sexually violent predators,” the “likelihood of the sex offenders engaging in repeat acts of predatory sexual violence is high.” Id. (emphasis added). That language bears a striking similarity to the common and dictionary definitions of “likely” as being “highly probable.” Construing the term as meaning “highly probable” also gives effect to the legislative decision to distinguish the standard in the [Act] from that in the general commitment statute, which requires showing behavior that “can reasonably be expected ... to result in serious physical harm.” A.R.S. § 36-501.5 (1993). If the legislature had intended the same standard to apply in the two statutory schemes, we think the legislature would have used the same terms. Use of “likely” rather than “reasonably expected” indicates the legislature intended to adopt a more stringent standard in the [Act].

EVIDENTIARY ISSUES
¶ 25 Wilber alleges the trial court erred in: (1) admitting two of his prior convictions; (2) allowing the State to admit hearsay statements by asking Wilber on the stand to verify statements from a presentence report; and (3) permitting the State to ask Wilber irrelevant questions. Because we are remanding for another commitment hearing, some of these evidentiary issues may recur and therefore we will briefly address them.
Prior Convictions
¶ 26 Wilber first challenges the trial court’s admission of his 1983 conviction for oral copulation of a child in California. The State responds that the 1983 conviction is a *308 “sexually violent offense” as defined in the Act, see A.R.S. § 36-3701(6), and thus was a necessary element for the jury to find Wilber to be an SVP. We agree.
¶27 Sexual conduct with a minor under A.R.S. § 13-1405 constitutes a sexually violent offense under the Act. See A.R.S. § 36-3701(6)(a); A.R.S. § 13-1405(A) (2001) (“A person commits sexual conduct with a minor by intentionally or knowingly engaging in sexual intercourse or oral sexual contact with any person who is under eighteen years of age.”). Wilber’s 1983 conviction constitutes a sexually violent offense under Arizona’s Act even though the conviction occurred in California. See A.R.S. § 36-3701(6)(d) (sexually violent offense means “[a]n act committed in another jurisdiction that if committed in this state would be a sexually violent offense listed in subdivision (a) or (b) of this paragraph.”). Accordingly, the trial court did not err in admitting Wilber’s 1983 conviction for oral copulation with a child. 6
¶28 Wilber also complains that the trial court incorrectly admitted his 1995 conviction for indecent exposure because indecent exposure is not considered a sexually violent offense under the Act. The record reveals, however, that Wilber stipulated that the 1995 conviction would be admissible under Arizona Rule of Evidence 609, presumably for impeachment purposes. 7 If the State on remand offers evidence of the 1995 conviction for the purpose of impeachment, the trial court should again consider the admissibility of the evidence under Rule 609.
Hearsay Statements
¶29 Wilber argues that the trial court erred by allowing the State to ask him what was said in a presentence investigation report about a 1997 aggravated assault conviction. Wilber claims that this method of questioning impermissibly allows hearsay in through the “backdoor” by asking a witness to confirm a hearsay statement. Because the State can prove a prior conviction without resort to a presentence report — and indeed proved it with proper documentation at trial — it is unlikely that this issue will recur on remand. We do not perceive a need to address the issue further.
Irrelevant Questions
¶ 30 Finally, Wilber asserts that the trial court allowed the State to ask him irrelevant questions. Specifically, the State asked Wil-ber about the length of his prison sentence and the duration of his second marriage. Because these particular questions may not necessarily be asked on remand, we decline to address Wilber’s relevancy objections at this time.
Conclusion
¶ 31 We vacate Wilber’s commitment order and remand for further proceedings consistent with this decision.
Notes
. The Kansas SVP act defines a “sexually violent predator” as "any person who has been 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 the predatory acts of sexual violence.” Kan. Stat. Ann. § 59-29a02(a) (1994). A "mental abnormality" is a "congenital or acquired condition affecting the emotional or volitional capacity which predisposes the person to commit sexually violent offenses in a degree constituting such person a menace to the health and safety of others.” Kan. Stat. Ann. § 59-29a02(b).
. Prior to
Leon G.,
this court in
Martin v. Reinstein,
. We note that this court in
Leon G.
did not, in reaching its opposite conclusion, focus on the term "makes.” Also, our colleagues in
Leon G.
quoted a law-psychology journal article discussing a difference between a desire not resisted and an irresistible desire.
. This suggested instruction is only part of the necessary instructions. For example, the jury must be instructed on the definition of a “sexually violent person,” see A.R.S. § 36-3701(7), in addition to the meaning of the phrase “mental disorder.” See A.R.S. § 36-3701(5).
. The psychologist who evaluated Wilber did not provide any testimony suggesting that Wilber had any problem controlling his behavior, let alone a serious difficulty in controlling his behavior. Nor did the prosecutor argue in closing argument that Wilber lacked the ability to control his behavior. Finally, Wilber did not admit that he had any difficulty in controlling his behavior.
. Wilber also argues that the 1983 conviction should not be admitted because it is more than ten years old, citing Ariz. R. Evid. 609(b) ("Evidence of a conviction under this rule is not admissible if a period of more than ten years has elapsed since the date of the conviction .... ”). The Arizona Rules of Evidence do apply to proceedings under the Act, see A.R.S. § 36-3704(B), but Rule 609 pertains to impeachment of a witness by a prior conviction. The State offered the 1983 conviction as substantive evidence of an element of the Act and not for impeachment purposes. Accordingly, the time limitation in Rule 609(b) for a prior conviction offered for impeachment is not applicable here. Under the Act, a person can be found to be an SVP if the person has "ever been convicted” of a sexually violent offense and meets other requirements. A.R.S. § 36-3701(7)(a).
. "Indecent exposure to a person under the age of fifteen years is a class 6 felony.” A.R.S. § 13-1402 (2001).
