    I.    INTRODUCTION
    After an involuntary commitment trial, the superior court issued an order
    committing the respondent to the Alaska Psychiatric Institute (API) for 90 days. The
    respondent appeals, arguing that the jury was incorrectly instructed on the unanimity
    requirement relating to a finding of grave disability. He also argues that the court erred
    in finding there was sufficient evidence that his condition would improve with treatment
    to support an involuntary commitment order. On the second issue, his appeal raises
    questions regarding the applicable legal standard. We conclude that any error in the jury
    instructions was invited error, that the superior court applied the correct legal standard
    regarding respondent’s chance of improvement, and that the court’s finding on that issue
    is supported by the record and not clearly erroneous. We affirm the superior court’s
    commitment order.
    II.   FACTS AND PROCEEDINGS
    In August 2016, after Darren M.1 removed the screen from the window of
    his third-floor apartment, he told his niece that he intended to jump. The niece called an
    ambulance, which transported Darren to the psychiatric emergency department at
    Providence Alaska Medical Center (Providence). Later that same day, a counselor at
    Providence filed a petition for an order authorizing Darren’s hospitalization for
    evaluation based on her determination that Darren, who had previously been diagnosed
    with bipolar disorder, was gravely disabled and a danger to himself or others. The
    petition alleged that Darren presented “with loose associations, actively talking to
    himself, appearing psychotic” and that he was not taking his medications.
    The superior court granted the petition and ordered Darren to be admitted
    to API for a mental health evaluation to be completed within 72 hours. The State,
    representing API, subsequently filed a petition seeking to have Darren committed to API
    for 30 days. After a hearing on Darren’s mental condition, the court granted the petition
    on the basis that Darren was mentally ill and likely to cause harm to himself or others.2
    Near the end of the 30-day commitment period, the State filed another petition seeking

    to extend Darren’s commitment for an additional 90 days. The petition alleged that
    Darren was mentally ill, that as a result he was both gravely disabled and likely to cause
    harm to himself or others,3 that there was reason to believe his mental condition could
    be improved with treatment,4 and that there was no less restrictive treatment alternative
    available. Before trial, the State withdrew the allegation that Darren presented a risk to
    himself or others, proceeding solely on a theory of grave disability. A bifurcated trial
    was held in October 2016: a six-person jury5 considered whether Darren was mentally
    ill and as a result gravely disabled, and a subsequent bench hearing was held on whether
    a less restrictive treatment alternative was available and whether there was reason to
    believe Darren’s mental condition could improve with treatment.
    A.     Testimony Before The Jury
    At the jury portion of the trial, Darren’s niece, daughter, and son all testified
    about Darren’s mental condition, living situation, and recent behavior. The jury also
    heard testimony by Gerald Martone, a psychiatric nurse practitioner and Darren’s
    primary care provider at API. The court recognized Martone as an expert witness.
    Darren’s daughter testified that Darren has a history of mental illness going

    Under AS 47.30.730(a)(1), a petition for a 30-day commitment must allege
    that the respondent, as a result of mental illness, is gravely disabled or likely to cause
    harm to himself or others. The allegation requirements for 30-day commitment petitions
    are incorporated by reference in the statutes regarding petitions for 90-day and 180-day
    commitment orders. See AS 47.30.740(a); AS 47.30.770(a). The court may commit a
    respondent on any one or more of those grounds. See AS 47.30.735(c);
    AS 47.30.755(a); AS 47.30.770(b)-(c).

    Under AS 47.30.730(a)(3), a commitment petition based on a theory of
    grave disability must allege “that there is reason to believe that the respondent’s mental
    condition could be improved by the course of treatment sought.”

    back to the 1980s when he was diagnosed with bipolar disorder. Darren lived with her
    in Oregon from approximately October 2015 until April 2016; in that time she observed
    that Darren struggled “with bouts of mania and depression”; suffered from paranoia,
    delusions, “racing thoughts,” and insomnia; and was “not able to hold a conversation.”
    In the spring of 2016, Darren moved to Alaska and lived with his niece
    while she helped him find senior housing. After Darren transitioned to independent
    living in senior housing, it appears his condition declined further: his niece, daughter,
    and son all expressed concern about Darren’s ability to care for his own needs. The
    niece testified that Darren would become forgetful when cooking and that he confused
    his current address with one for a home where he had not lived in 15 years. Darren’s
    daughter testified that his apartment was “a little messy” and that she found clothing
    soiled with feces in the bathroom garbage that “smelled like it had been there for a little
    while.” His son testified that Darren stopped buying groceries when he had previously
    gone shopping almost daily, that he “wasn’t eating very well,” and that he started
    drinking “much more than he . . . ever normally would,” to the point of scaring other
    residents of his apartment complex, as well as falling down and breaking his collar bone.
    Their testimony was particularly concerned with Darren’s ability to care for
    his medical needs. The daughter testified that in August 2016, Darren told her “[h]e
    hadn’t been taking his medications since spring.” She testified that Darren “did not
    understand that you have to make appointments” to see a doctor. On one occasion,
    Darren had told her that he had walked into a doctor’s office concerned that “his mouth
    was cancerous” and demanded a biopsy; because he did not have an appointment, “he
    just left and didn’t get screened at all and didn’t make . . . an appointment for the future.”
    The niece testified that Darren believed “doing arm exercises and push ups to help
    strengthen him” would help heal his fractured collar bone. The niece testified that she
    -4-                                        7298
    had discovered an empty bottle of heart medication in Darren’s apartment; this
    concerned her because she had previously seen the bottle full with enough pills in the
    bottle to “last quite a while.” Her testimony also indicated that she was not sure her
    uncle knew what the medication was: Darren told her it was not actually his medication
    but that he had found it on the bus and taken pills from it anyway. The niece also
    testified that she once found Darren with “very swollen” legs that he “didn’t seem
    concerned about” and a black eye that he was seemingly unaware of and could not
    explain.
    Darren’s niece testified in detail about the events of August 19, 2016, the
    day she called the ambulance. Earlier, either that morning or the day before, Darren had
    pulled the communal fire alarms in his buildings, apparently out of concern that they
    were not working. The niece later found Darren with his coat on inside his apartment
    with the window open and the screen removed. When she asked why his windows were
    open, Darren responded that “the fire alarms weren’t working and that he had to jump”
    but that he first needed to buy a candle from the store. Concerned that Darren might
    actually jump from the third-floor window, the niece called for an ambulance to take
    Darren to Providence. While the two waited for the ambulance, Darren told his niece
    that a nearby streetlight would turn on if tapped three times with a lighter or rock and
    indicated an interest in rewiring the light “to make it stay on.”
    Darren’s son and daughter testified about his condition during his initial 30­
    day commitment. When his daughter visited him, Darren insisted they sit at the
    children’s table so that he could see out the front door and “see who was coming in and
    going out,” expressed concerns about keeping her safe, and wanted the police to be
    present during her visit. She noticed various cuts, scrapes, and bruises on her father, as
    well as swollen ankles, and she worried he was not taking care of his congestive heart
    -5-                                       7298
    failure. Darren did not take his medications consistently, and he told his daughter that
    taking his medications would “make him visible” and prevent him from protecting her
    and her brother. Darren told her that he wanted “to get a handgun as soon as he gets out
    of API” and told his niece that “he wanted to get a gun because he didn’t want his son
    to know where he lived.” According to his son, Darren likened himself to Jack Ruby6
    and believed he “would be fit to be . . . [a] contract killer.” The son testified that Darren
    suffered from delusions, describing demons and “religious, spiritual things” that others
    could not see. The son also noticed a cut on Darren’s leg that Darren said he sustained
    when “the floor came up and cut him,” referencing the “T-1000,” a shape-shifting
    android assassin featured in the movie Terminator 2.
    Martone testified that in addition to bipolar illness, Darren suffers from
    Korsakoff syndrome, which is a form of permanent, irreversible nerve damage caused
    by vitamin B1 deficiency, and which is most commonly a result of chronic alcoholism.
    He testified that Korsakoff syndrome causes brain function to deteriorate, resulting in
    confusion, eye-twitching, and a tendency to “confabulate” — inventing information to
    fill in for knowledge deficits — all of which were symptoms he saw in Darren. Bipolar
    illness, by contrast, is a mood disorder that involves “cycling between extremes of
    moods, both highs and lows.” Martone testified that while “people with bipolar in a
    manic state have poor judgment and decision making,” bipolar illness would not cause
    the confusion Darren was exhibiting.

    -6-                                       7298
    Martone testified that Darren’s “reality decision making [was] impaired,” that Darren
    “[did] not know the consequences of his action[s],” that “he [did] not have insight into
    his illness,” and that he was unable to communicate coherently. Martone explained that
    a “KELS test” — an “evaluation of living skills” — was given to Darren at API, and the
    test indicated that Darren “would need assistance to perform his activities of daily living
    independently.” Martone also testified that Darren would not “be safe in the community
    if he were to be released [at the time of trial]” because “his judgment [was] very
    impaired,” he “ha[d] trouble forming new memories,” and he would “get[] easily angered
    and irritated.” By contrast, Martone testified that API would be a “very safe place” for
    Darren. Finally, Martone corroborated the daughter’s testimony that Darren did not
    always take his medication, against Martone’s advice.
    Darren did not testify and did not call any witnesses on his behalf.
    B.     The Jury Instructions And The Jury’s Findings
    After the close of evidence, the superior court instructed the jury on the
    findings it was required to make. Instruction 12 told the jury: “[Darren] should be
    involuntarily committed for treatment at Alaska Psychiatric Institute only if you find that
    the [S]tate has proved by clear and convincing evidence that [he] is mentally ill and as
    a result is gravely disabled.” Instruction 14 defined the term “gravely disabled”:
    Gravely disabled means a condition in which a person,
    as a result of mental illness:
    (1) is in danger of physical harm arising from such
    complete neglect of basic needs for food, clothing, shelter or
    personal safety as to render serious accident, illness or death
    highly probable if care by another is not taken; or
    (2) will, if not treated, suffer or continue to suffer
    severe and abnormal mental, emotional or physical distress,
    and this distress is associated with significant impairment of judgment, reason or
    -7-                                      7298
    behavior causing a substantial deterioration of the person’s previous ability to function
    independently. This distress refers to a level of incapacity that prevents the person in
    question from being able to live safely outside of a controlled environment.[7]
    Instruction 22 informed the jury about the unanimity requirement:
    To reach a verdict in this case, five of you must be in
    agreement as to each answer you give on the special verdict
    form. The same five jurors need not agree as to every
    answer, as long as any combination of five jurors agrees to
    each answer on the special verdict form.
    The special verdict form given to the jury asked two questions: whether the State had
    proved by clear and convincing evidence that Darren was mentally ill, and whether the
    State had proved by the same standard that Darren was gravely disabled as a result.
    While Darren’s attorney made some pre-trial objections to the State’s
    proposed grave disability instruction, the instructions used by the court on the issues of
    grave disability and jury unanimity, as well as the special verdict form, were all either
    identical or nearly identical to the instructions and verdict form Darren’s attorney had
    proposed. At trial, neither party made further objections regarding the substance of
    either the jury instructions or the verdict form.8
    The jury returned a verdict finding that the State had proved by clear and
    convincing evidence that Darren was both mentally ill and as a result gravely disabled.
    7
    Apart from the final sentence of subdivision (2), this definition mirrors
    verbatim the statutory definition of “gravely disabled” provided in AS 47.30.915(9). The
    final sentence reflects our decision in Wetherhorn v. Alaska Psychiatric Institute, in
    which we held that the second part of the statutory definition was constitutional only “if
    construed to require a level of incapacity so substantial that the respondent is incapable
    of surviving safely in freedom.”

    The parties did ask for a correction to a clerical error in the jury unanimity
    instruction, which the court granted.

    C.     Post-Trial Hearing And Court Order
    The day after the jury verdict, the court held an evidentiary hearing on the
    two remaining issues: whether there was reason to believe Darren’s mental condition
    could be improved by treatment and whether involuntary commitment at API was the
    least restrictive treatment alternative. The State again called Martone as an expert
    witness. Darren did not testify or call any witnesses.
    Martone’s testimony was primarily focused on the issue of improving
    Darren’s condition. In his testimony before the jury, Martone had testified that
    Korsakoff syndrome is a “permanent, irreversible” condition and that Darren’s bipolar
    illness is a “lifelong diagnosis.” At the bench hearing, Martone nonetheless testified that
    with treatment, Darren’s Korsakoff symptoms had already “improved slightly” and that
    he would “expect a slight more improvement.” Specifically, Martone testified that daily
    doses of vitamin B1 had caused a slight improvement in Darren’s eye twitching and that
    further improvement, including to Darren’s “thinking or perceptions,” could be possible.
    He testified that “in 25 percent of cases, you can have a slight improvement if you’re
    consistently getting vitamin B1 every day,” although he could not say whether Darren
    would be in that group. Martone testified that some of Darren’s other symptoms —
    specifically, his agitation, frustration, delusions, and paranoia — as well as his bipolar
    illness, could be treated with the antipsychotic drug Haldol (a brand name for
    haloperidol), though they would likely not be completely relieved. Martone also testified
    that Darren was already showing signs of improvement from treatment with Haldol.
    With respect to Darren’s confusion, however, Martone testified that it was a result of
    Korsakoff syndrome and therefore he would “only expect . . . a slight improvement.”
    On the issue of less restrictive treatment alternatives, Martone testified that
    Darren was not “showing insight into his mental illness,” that Darren had refused to
    -9-                                        7298
    discuss the idea of working with an outpatient provider, and that Darren was “too
    agitated and disorganized” to work with an outpatient provider if he were ordered to do
    so. However, Martone believed it would be possible for Darren to improve to such an
    extent that he might at some point be able to work with an outpatient provider. On cross-
    examination, Martone repeated many of the same points, and testified that API’s goal
    was not to keep Darren long term but to “hold him and try to treat him until [they could]
    find a suitable place for him . . . to live . . . with a little more freedom[].”
    In closing, the State asked the court to find “that there’s reason to believe
    that the respondent’s mental condition could be improved by treatment” and “that
    commitment is the least-restrictive alternative.” Darren argued that the State had not met
    its burden to prove either of these requirements by clear and convincing evidence.
    Specifically, Darren argued the State’s showing was insufficient because, as Martone
    testified, Darren’s Korsakoff syndrome could not be cured, and because there was only
    a 25 percent chance of even a slight improvement, with no indication that Darren was
    within those 25 percent. The State argued in rebuttal that Martone had testified to actual
    and expected improvement in other symptoms, such as Darren’s paranoia, agitation, and
    delusions, and asserted that the law requires only “an improvement in the [respondent’s]
    mental condition” viewed broadly, and that the State need show only a likelihood of
    improvement, not of “great improvement.” Darren’s attorney added as a concluding
    remark that she believed it to be “a very dangerous thing to think that slight improvement
    would qualify.”
    The superior court expressed frustration with the case on two points: first,
    API expected only “slight improvement” in Darren’s condition whereas “the amount of
    liberty that’s being taken away is great”; second, because there are no alternative
    facilities available in Anchorage, the only options were that “someone is locked up and
    -10-                                    7298
    treated or they’re let go in the streets and there’s no treatment.” Even so, the court held
    that the State met its burden to prove by clear and convincing evidence that “treatment
    could improve [Darren]” and that “there is not . . . presently a less-restrictive treatment
    [alternative].”
    Based on the findings from the jury trial and the bench hearing, the court
    issued an order committing Darren to API for 90 days. Darren appeals.
    III.   STANDARD OF REVIEW
    “We apply our independent judgment to the interpretation of the Alaska
    Constitution and statutes, adopting ‘the rule of law that is most persuasive in light of
    precedent, reason, and policy.’ ”9 We review factual findings in involuntary commitment
    proceedings for clear error, and “we reverse only if our review of the record leaves us
    with a definite and firm conviction that a mistake has been made.”10
    “Invited error ‘occurs when the court takes erroneous action at the express
    request of [a party], and then [that party] urges reversal on that basis on appeal.’ ”11
    When an alleged error is invited, we examine that error to see whether there is an
    “exceptional situation” making reversal “necessary to preserve the integrity of the
    judicial process or to prevent a miscarriage of justice.”12

    “We apply our independent judgment in determining mootness because, as
    a matter of judicial policy, mootness is a question of law.”13
    IV.    ANALYSIS
    Darren challenges the superior court’s commitment order on two grounds.
    He argues that the court erred (1) in how it instructed the jury on the grave disability
    issue and (2) in finding that there was sufficient evidence that Darren’s condition would
    improve with treatment. For the reasons discussed below, we affirm the commitment
    order.14
    A.     Any Error In The Challenged Jury Instructions Was Invited Error.
    Under AS 09.20.100, “not less than five-sixths of the jury may render a
    verdict, which is entitled to the legal effect of a unanimous verdict at common law.” At
    the conclusion of the jury trial, the jury was asked on the special verdict form whether
    the State had shown, by clear and convincing evidence, that Darren was “gravely
    disabled” as a result of mental illness. The jury returned a special verdict form indicating
    that at least five of six jurors believed the State had done so. However, both the statutory
    definition of “gravely disabled”15 and the one provided to the jury contain two
    13
    Long v. Arnold, 
    386 P.3d 1217
    , 1223 n.19 (Alaska 2016) (quoting Akpik
    v. State, Office of Mgmt. & Budget, 
    115 P.3d 532
    , 534 (Alaska 2005)).
    14
    The State contends that Darren’s appeal is moot because the commitment
    order has already expired and Darren has already been released from API. However, the
    State suggests that this court “may wish to hear his appeal on the merits under a
    mootness exception” — specifically, the public interest exception. See In re Tracy C.,
    
    249 P.3d 1085
    , 1089-90 (Alaska 2011). Darren appears to concede that his appeal is
    technically moot, but he argues that the public interest exception applies and that we
    should hear the case on its merits. We agree and will consider this appeal.

    AS 47.30.915(9).
    -12-                                       7298
    subdivisions, allowing the jury to conclude that Darren was gravely disabled either
    because he was in danger of physical harm arising from neglect of his basic needs or
    because severe and abnormal distress associated with significant impairment of
    judgment, reason, or behavior rendered him incapable of living safely outside a
    controlled environment. Darren argues that it was legal error for the court not to instruct
    the jury that it had to agree on a specific part of the definition as the basis for its verdict.
    Darren did not raise this issue before the trial court: he did not object to the
    court’s jury instruction and did not request a jury instruction that would require the jury
    to agree on a specific basis for a finding of grave disability. On the contrary, the court’s
    jury instructions defining “gravely disabled” and explaining the jury unanimity
    requirement, as well as the special verdict questions, are effectively identical to those
    Darren himself requested.
    It is clearly established under Alaska law that a party cannot complain of
    errors in jury instructions after that party requested, approved, or advocated for the
    disputed instructions at trial. For example, in Power Constructors, Inc. v. Taylor &
    Hintze, we held that the plaintiff’s claim of error was waived when the plaintiff expressly
    endorsed the instructions that were read to the jury.16 This principle derives from Alaska
    Civil Rule 51(a), which provides that “[n]o party may assign as error the giving or the
    failure to give an instruction unless the party objects thereto before the jury retires to
    consider its verdict, stating distinctly the matter to which the party objects and the
    grounds of the objection.”

    When a party on appeal urges reversal on the basis of an allegedly
    erroneous action taken by the court at the express request of that party, the error — if any
    — is invited error.17 “When an error is invited, an appellate court examines the error to
    see if there is an ‘exceptional situation’ where reversal is necessary to preserve the
    integrity of the judicial process or to prevent a miscarriage of justice.”18 The facts of this
    case do not come near this level. Darren concedes that “API’s case supported both
    theories of grave disability,” and he has not articulated — beyond merely conclusory
    statements — how the alleged error was prejudicial. We hold that any error in the jury
    instructions was invited error and that Darren waived any challenge to the instructions
    given to the jury on the issue of grave disability when he himself requested them.19
    B.	    There Was No Error In The Court’s Chance-Of-Improvement
    Finding.
    Darren next argues that “the trial court erred in concluding that Darren’s
    condition would improve with commitment and treatment.” Darren’s argument is
    primarily a sufficiency of the evidence argument, that the evidence “does not support a
    finding that treatment will improve his condition.” But Darren also raises a legal
    argument regarding the standard of what the State must prove — must the State prove
    that treatment “will” improve the respondent’s condition, or that treatment “could”
    improve respondent’s condition? We will first clarify the legal standard before

    Our statement should not be read as implying that the superior court’s jury
    instruction was actually erroneous. We do not reach that issue because the alleged error
    was invited.

    addressing whether the evidence meets that standard.
    1.	    The court applied the correct legal standard to the chance-of­
    improvement issue.
    The superior court “determined by clear and convincing evidence that there
    is reason to believe that [Darren’s] mental condition could be improved by treatment.”
    Darren argues that the court applied the wrong standard, and that Darren could be
    “committed for grave disability only upon a finding that treatment will improve [his]
    condition.” (Emphasis added.) The State contends that Darren mischaracterizes the
    applicable standard and that the evidence presented “amply satisfie[d] the statutory
    requirement that there be reason to believe Darren’s condition could improve.”
    The question whether a respondent’s mental condition is likely to improve
    with treatment derives from Alaska’s involuntary commitment statutes, as revised in
    1981. As expressed in AS 47.30.655(6), one of the principles underlying the revision
    was “that persons who are mentally ill but not dangerous to others be committed only if
    there is a reasonable expectation of improving their mental condition.” Pursuant to that
    principle, a petition for involuntary commitment “must . . . allege with respect to a
    gravely disabled respondent that there is reason to believe that the respondent’s mental
    condition could be improved by the course of treatment sought.”20 Curiously, the
    legislature did not include an explicit requirement that the State make a corresponding
    showing, and the commitment statutes do not mention the question of improvement with
    treatment again.
    If read literally, the statutes require the petitioner to allege a possibility of
    20
    AS 47.30.730(a)(3) (requiring this allegation in a petition for 30-day
    commitment); see AS 47.30.740(a) (incorporating the same requirement in the procedure
    for seeking a 90-day commitment); AS 47.30.770 (incorporating the same requirement
    for 180-day commitment petitions).
    -15-	                                        7298
    improvement but allow the court to commit the respondent without having to make any
    finding on that topic, as long as the court “finds, by clear and convincing evidence, that
    the respondent is mentally ill and as a result is likely to cause harm to the respondent or
    others, or is gravely disabled.”21 Of course, this literal reading of the statutory
    requirements would run directly contrary to the underlying legislative statement of
    purpose “that persons who are mentally ill but not dangerous to others be committed only
    if there is a reasonable expectation of improving their mental condition.”22
    We have addressed this issue only once before. In E.P. v. Alaska
    Psychiatric Institute we were asked whether the State has to prove a likelihood of
    improvement when it seeks to commit a person who poses a danger to himself.23 Based
    on the language of AS 47.30.655(6), E.P. argued that a finding of likely improvement
    is required in all cases where the respondent does not pose a harm to others — that is,
    both in cases where the respondent is gravely disabled and in cases where he is likely to
    cause harm to himself.24         We concluded that the statement of purpose in
    AS 47.30.655(6) conflicts with the substantive statutes regarding the required allegations
    and that the substantive statutes control.25 Because the substantive statutes require
    alleging a possibility of improvement only “with respect to a gravely disabled
    21
    AS 47.30.735(c) (requiring this finding for 30-day commitment orders); see
    AS 47.30.755(a) (incorporating the same for 90-day commitments); AS 47.30.770(b)
    (incorporating the same for 180-day commitments).

    respondent,” we held that “the state is not required to show a likelihood that, in the case
    of a mentally ill person who poses a danger to himself, treatment will improve his
    condition.”26
    Underlying our decision in E.P. was the assumption that the State is
    required to show an expectation of improvement in the case of a gravely disabled
    person.27 But in that case we directly addressed only the question whether such a
    requirement also applies to proceedings based on a theory of self-harm, and we declined
    to extend the requirement to that context.28 We now clarify that the assumption in E.P.
    was correct. It would be absurd to interpret the commitment statutes to require the State
    to allege a fact that has no further relevance to the subsequent proceedings. It is also
    clear that the State, API, and the Public Defender Agency have all been operating under
    the assumption that this finding is required in the grave disability context, at least since
    2009 when E.P. was decided; we see no reason to change this, particularly since neither
    party has asked us to. We therefore hold that when the State seeks to commit a mentally
    ill person on a theory of grave disability, it must prove a reasonable expectation of
    improvement with treatment.
    We also hold that this showing must be made by clear and convincing
    evidence. In In re Stephen O. we explained that the “clear and convincing” standard
    applies to all findings relevant to involuntary commitment “to impress the factfinder with
    the importance of the decision and thereby perhaps to reduce the chances that
    26
    
    Id. 27 See
    id. at 1109.

    -17-                                       7298
    inappropriate commitments will be ordered.”29 Although In re Stephen O. only expressly
    addressed the burden of proof for the findings required by statute, the same underlying
    policy is applicable to all required findings in involuntary commitment cases “because
    of the great ‘importance of the liberty right involved’ and the ‘massive curtailment of
    liberty’ that such commitments entail.”30
    The question, then, is to what level of certainty the State is required to show
    a possibility of improvement with treatment. Again, the only relevant precedent is E.P.,
    in which we assumed what we have now concluded — that a person can be committed
    for grave disability only upon a showing of possible improvement with treatment.
    However, E.P. does not provide a clear answer to the question of what, exactly, the State
    must show. In a section heading, we stated in E.P. that “A Person Can Be Committed
    for Grave Disability Only upon a Finding that Treatment Will Improve the Person’s
    Condition.”31 This is the formulation Darren asks us to adopt, and it is the most strict
    formulation of this requirement found anywhere in E.P. We also used similar phrases
    such as “that treatment will lead to improvement.”32 But our opinion in E.P. also phrased
    the required showing as “reason to believe that the respondent’s mental condition could
    be improved by treatment,” and as “a likelihood that the respondent’s condition could

    applies in grave disability cases but declined to extend it to the self-harm context.

    be improved by treatment.”33 Our opinion did not explain whether improvement has to
    be definitive or merely possible — whether treatment “would” or “could” result in
    improvement — and did not clarify whether the State has to conclusively prove that there
    is a chance of improvement or merely show that there is “reason to believe” that
    treatment could improve the respondent’s condition.
    As discussed above, the commitment statutes do not explicitly require the
    court to make any finding on this issue; they merely require the initial petition to allege
    that “there is reason to believe that the respondent’s mental condition could be improved
    by the course of treatment sought.”34 But this guidance is sufficient, as it provides a clear
    formulation of what the legislature intended, and we decline to deviate from this statutory
    language. The formulation Darren promotes is simply too strict: as Martone’s testimony
    in this case indicates, psychiatric medicine rarely promises absolutely certain results.
    Requiring the State to prove that treatment definitely would improve Darren’s condition
    would be a tall order, and one that medical science might struggle to fulfill even under
    ideal circumstances. We therefore hold that the State was required to prove, by clear and
    convincing evidence, exactly what it was required to allege: that there was reason to
    believe that Darren’s mental condition could be improved by the course of treatment
    sought. The superior court applied the correct standard when deciding this issue.
    2.	    The court’s chance-of-improvement finding is supported by
    substantial evidence and was not clearly erroneous.
    Martone testified that 25% of Korsakoff patients experience a “slight
    improvement” with treatment but that he could not tell whether Darren would be in that
    25% group. Darren argues that this is simply too speculative to satisfy the State’s

    burden; because Korsakoff syndrome is an irreversible condition, he contends the State
    failed to show that Darren was likely to improve with treatment.35 However, Martone
    also testified that Darren had already seen slight improvement in his Korsakoff
    symptoms, and he explained a number of other ways in which treatment would benefit
    Darren, particularly in reducing Darren’s symptoms of bipolar disorder, such as agitation
    and paranoia. Martone’s testimony did not indicate that this improvement was a mere
    possibility, as was the case with the Korsakoff treatment; rather, Martone expected
    Darren’s agitation to attenuate and diminish. And while Martone testified that Korsakoff
    syndrome was Darren’s “primary diagnosis,” he also testified that the main reason why
    Darren was unable to work with an outpatient provider — and thus why Martone
    believed commitment was appropriate — was Darren’s agitation, disorganization, and
    paranoia resulting from his bipolar disorder. When asked whether, with treatment,
    Darren “could improve to the extent that at some point he may be able to work with an
    outpatient provider,” Martone indicated that Darren could, answering: “That’s the goal.”
    On this record, we conclude that there was substantial evidentiary support
    for the superior court’s finding that there was reason to believe Darren’s mental
    condition could be improved with treatment, and the court’s finding was therefore not
    clearly erroneous.
    V.    CONCLUSION
    We AFFIRM the superior court’s commitment order.
    35
    Darren’s brief interprets Martone’s testimony as concluding that Darren
    suffers only from Korsakoff syndrome, and not also from bipolar disorder. Darren is
    clearly mistaken. Martone consistently testified that Darren suffers from both conditions
    and that while Darren’s confusion is attributable to Korsakoff syndrome, several other
    of his mental symptoms are attributable to bipolar disorder.
