OPINION
[ 1 Phong Nguyen appeals from his convictions for two counts of aggravated sexual abuse of a child, first degree felonies, see Utah Code Ann. § 76-5-404.1 (2008); two counts of sodomy on a child, first degree felonies, see id. § 76-5-403.1; and one count of attempted rape of a child, a first degree felony, see id. §§ 76-4-102(c), -5-402.1. Nguyen argues that the trial court erred in admitting the videotaped testimony of the eleven-year-old child victim (Stepdaughter) 1 and that the prosecutor violated Nguyen's Fifth Amendment right to remain silent, see U.S. Const. amend. V, by inappropriately commenting on his decision not to testify. We affirm.
BACKGROUND
12 Nguyen was charged with multiple sex offenses based on allegations made by Stepdaughter. According to Stepdaughter, there were three separate incidents of sexual abuse that occurred between December 2006 and June 2007. In September 2007, a detective interviewed Stepdaughter at the Children's Justice Center. In the videotaped interview, Stepdaughter described each incident in detail. While doing so, Stepdaughter began sobbing; the videotape reflects that Stepdaughter continued to ery for about three minutes before the interview could continue.
3 The prosecution requested that the trial court admit the videotape of the interview at trial pursuant to Utah Code section 76-5-411 (the Statute) and rule 15.5 of the Utah Rules of Criminal Procedure (the Rule) (collectively, the child witness exception). 2 Nguyen objected to the admission of the videotaped testimony, arguing that the State had failed to demonstrate "good cause" for admitting it, see generally Utah R.Crim. P. 15.5(1), and that doing so was not in the "interest of justice," see generally id. R. 15.5(1)(g); Utah Code Ann. § 76-5-411(2). The trial court concluded that the interview met the reliability requirements of the child witness exception and that admitting it was in the interest of justice, but did not make a separate finding that there was good cause to admit the videotaped interview.
At trial on October 29, 2008, a version of the videotaped interview, from which the three minutes of sobbing had been redacted, was played for the jury. Stepdaughter also testified in person, confirming that the statements she made in her interview were true and answering general questions regarding the abuse and her subsequent disclosure. However, Stepdaughter did not repeat the details of the three incidents during her live testimony at trial. *538 Nguyen's counsel chose not to cross-examine Stepdaughter and did not call any defense witnesses; Nguyen exercised his right not to testify provided by the Fifth Amendment to the United States Constitution. See generalty U.S. Const. amend. V 3
T5 During closing argument, the prosecutor reminded the jury of the trial court's instruction to base the verdict "only on the evidence produced here in court," and then stated that the only evidence of what occurred was presented by Stepdaughter, whose testimony was not contested or impeached. Upon objection from the defense, the lawyers participated in an off-the-record discussion with the trial judge. Both parties agree that the defense made a motion for a mistrial on the ground that the prosecutor's comments were an indirect comment on Nguyen's decision not to testify. When the court allowed the prosecutor to continue, the prosecutor again emphasized the defense's failure to present evidence contradicting Stepdaughter's testimony or suggesting a motive for Stepdaughter to prevaricate.
T6 The defense renewed its motion for a mistrial, arguing that the prosecutor's statements were "at a minimum an indirect reference [to] Mr. Nguyen not taking the stand." Although it considered the prosecutor's statements "close to the line," the trial court denied the motion for a mistrial. Instead, the trial court offered to give a curative instruction, which the defense declined. During the State's rebuttal argument, the prosecutor clarified,
[Defense counsel] has talked about the presumption of innocence, the right to remain silent, and no duty to present any evidence from the Defense. Those are absolute constitutional bedrock principles. I agree with them wholeheartedly. I have taken an oath as the State's prosecutor to uphold the Constitution of the United States, the State of Utah, and the laws of the State of Utah. I don't want you to do anything to abrogate those principles in this case.
The jury convicted Nguyen on all counts, and he filed a timely appeal.
ISSUES AND STANDARDS OF REVIEW
17 First, Nguyen argues that the trial court erred by admitting Stepdaughter's videotaped interview under the child witness exception because the trial court did not find good cause to admit the evidence. See Utah R.Crim. P. 15.5 (allowing the out-of-court statements of the child victim to be admitted at the trial of the accused perpetrator upon "good cause shown"). Whether the child witness exception requires the trial court to make a finding of fact on a specific matter is a question of law, which we review for correctness. See State v. McClellan,
T8 Second, Nguyen contends that the trial court should have granted his motion for a mistrial because the prosecutor inappropriately commented on Nguyen's decision not to testify. Although we "review rulings on motions for a mistrial based on prosecutorial misconduct for abuse of discretion," State v. Reed,
T9 Third, Nguyen asserts that reversal is warranted due to the combined prejudicial impact of the various errors he alleges were made in the trial court. We will reverse a jury verdict under the cumulative error doctrine only when the cumulative effect of the multiple yet individually harmless
*539
errors undermines our confidence that the defendant received a fair trial. See State v. Dunn,
ANALYSIS
I. Admission of Videotaped Testimony
110 Our rules of evidence are designed to permit the introduction of relevant and reliable evidence "to the end that the truth may be ascertained and proceedings justly determined." Utah R. Evid. 102. Generally, out-of-court statements offered for the truth of the matter asserted-hearsay-are not admissible. See id. R. 801(c), 802. However, various exceptions to that rule have been recognized, see id. R. 808, due to the acknowledgment that certain categories of hearsay statements are inherently reliable. See State v. Workman,
T11 In ruling on the State's motion to admit Stepdaughter's videotaped interview, the trial court made detailed written findings of fact on these factors and concluded that Stepdaughter's interview was reliable and that the interest of justice would best be served by its admission. Nguyen contests only one of these conclusions-that the interest of justice would be furthered by admitting the testimony, see Utah Code Ann. § T6-5-411(2); Utah R.Crim. P. 15.5(1)(g). However, Nguyen does so not by challenging the findings of fact that the trial court did make but by arguing that the interest of justice analysis also requires the trial court "to find that there was a need for the videotape and [that it was] not just a needless presentation of cumulative evidence." (Internal quotation marks omitted.) See generally Utah R.Crim. P. 15.5(1) (providing that a child victim's videotaped testimony is admissible "upon motion and for good cause shown" if the requirements of the Rule are met); Utah R. Evid. 408 (permitting exclusion of relevant evidence where "needless presentation of cumulative evidence" substantially outweighs the probative value of the evidence).
112 We begin our analysis by examining the language of the child witness exception. See State v. Harker,
(1) Notwithstanding any rule of evidence, a child victim's out-of-court statement regarding sexual abuse of that child is admissible as evidence although it does not qualify under an existing hearsay exception, if:
(a) the child is available to testify in court ...; [or]
*540 (c) the statement qualifies for admission under Rule 15.5(1), Utah Rules Criminal Procedure.
(2) Prior to admission of any statement into evidence under this section, the judge shall determine whether the interest of justice will best be served by admission of that statement. -In making this determination the judge shall consider the age and maturity of the child, the nature and duration of the abuse, the relationship of the child to the offender, and the reliability of the assertion and of the child.
(4) For purposes of this section, a child is a person under the age of 14 years.
Utah Code Ann. § 76-5-411 (emphasis added). 6
{13 The second provision that governed the child witness exception at the time of Nguyen's trial is the Rule, which then stated, in relevant part,
(1) In any case concerning a charge of child abuse or of a sexual offense against a child, the oral statement of a victim or witness younger than 14 years of age may be recorded prior to the filing of an information or indictment, and upon motion and for good cause shown is admissible as evidence in any court proceeding regarding the offense if all of the following conditions are met:
(1)(g) the court views the recording before it is shown to the jury and determines that it is sufficiently reliable and trustworthy and that the interest of justice will best be served by admission of the statement into evidence; and
(1)(h) the child is available to testify and to be cross-examined at trial ... or the court determines that the child is unavailable....
Utah R.Crim. P. 15.5 {emphases added). Our supreme court has noted that "all the requirements of both provisions must be met" for the child's out-of-court statement to be properly admitted. Seals,
114 Nguyen notes that the Rule states that it is applicable "upon motion and for good cause shown," and argues that this requires that the trial court make findings of fact supporting a conclusion that there is a special need for the evidence. We are not convinced. The good cause reference is qualified by the language "if all of the following conditions are met." See Utah R.Crim. P. 15.5(1). Those conditions are extensive and include subsection (8), which provides that the court must "view[ ] the recording before it is shown to the jury and determine[ ] that it is sufficiently reliable and trustworthy and that the interest of justice will best be served by admission of the statement into evidence."
7
Utah R.Crim. P. 15.5(l)(g). The concepts of "for good cause shown" and that "the interest of justice will best be served" are related.
8
See State v. Lamper,
1 15 Furthermore, Nguyen's interpretation is contrary to the evolution of and purpose behind Utah's child witness exception. The version of the Rule in effect at the time of Nguyen's trial provides different require
*541
ments for the admission of out-of-court statements of child victims who will "testify and ... be cross-examined at trial" than of those who will not. See Utah R.Crim. P. 15.5(1)(b). The trial court is required to make a finding similar to Nguyen's proposed "need for the evidence" only when the child will not also testify. See id. When the child will not be available for cross-examination at trial, the child's out-of-court statement is admissible only if "the court determines that the child is unavailable as a witness to testify at trial under the Utah Rules of Evidence," or the trial court determines, "based on medical or psychological evidence or expert testimony, that the child would suffer serious emotional or mental strain if required to testify at trial." Id. In determining whether a child is "unavailable," the trial court has sometimes considered the child's inability to testify meaningfully at trial. See, eg., State v. Thomas,
{16 Where the child will testify and be available for cross-examination, there is no requirement that the trial court find the child unavailable, whether as a result of serious mental strain or otherwise. See Utah R.Crim. P. 15.5(1)(h) (requiring a finding that the child is "unavailable" only if the child will not testify at trial) 9 Under those cireum-stances, both the Statute and the Rule require only that the conditions of reliability be met and that the interest of justice be best served by admission of the statement. See generally Utah Code Ann. § 76-5-411 (2008); Utah R.Crim. P. 15.5.
117 Despite this clear distinction in the plain language of the Rule, Nguyen asks us to impose an unavailability-type requirement, which he defines as a special need for the evidence, in situations where the child will testify. We conclude that to do so would add an unintended condition to the child witness exception to the hearsay rule. Nguyen's right of confrontation has not been denied or restricted. See State v. Pecht,
1 18 Instead, as with other hearsay exceptions, the focus in determining whether the interest of justice will best be served by admission of the out-of-court statement of a testifying child victim of sexual assault is on the reliability of that statement. See Utah R.Crim. P. 15.5(1)(a)-(g) (requiring conditions of reliability); see also Lamper, 779
*542
P.2d at 1129 (holding that the findings and conclusions explaining why "the interest of justice will best be served" by admitting the evidence "are to foeus on the trustworthiness and reliability of the [child's] out-of-court statements" (citing Nelson,
119 In State v. Pecht,
must specifically consider[ ] whether the interest of justice will best be served by admission of that statement. In making that determination the judge shall consider (1) the age and maturity of the child, (2) the nature and duration of the abuse, (8) the relationship of the child to the offender, and (4) the reliability of the assertion and of the child.
Id. 119 (internal quotation marks omitted); see also State v. Lamper, TT9 P.2d 1125, 1127-29 (Utah 1989) (applying both the Statute and the Rule and holding that the trial court was required "to enter findings and conclusions explaining in detail its analysis of the reliability and trustworthiness" of the out-of-court statement as well as "that the interest of justice will best be served by admission of the out-of-court statement" (internal quotation marks omitted)). But see State v. Nelson, TTT P.2d 479, 482 (Utah 1989) (holding that out-of-court statements were improperly admitted under the "catchall" exception to the hearsay rule, see Utah R. Evid. 807, and stating in dicta that "[uJn-der [the Statute], the court must carefully weigh the reliability of the statement and the need to admit it into evidence" (emphasis added)). Despite the specific finding by the Pecht trial court that the children were responsive and mature, the supreme court did not require any findings or conclusions regarding the cumulative nature of the evidence in light of the children's testimony, or regarding the prosecution's need for the videotapes. See Peckt,
T 20 That result is consistent with the purposes of the child witness exception. Admitting a child victim's videotaped testimony increases the likelihood that the testimony will be accurate. See State v. Loughton,
{21 Nguyen asks us to adopt an interpretation of the exception whereby the very factors that establish the reliability of Stepdaughter's videotaped interview-that Stepdaughter was too old to be easily coached, that she had an intact memory, and that she was articulate, rational, confident, and positive in her assertions-would prevent its admission as unnecessary. However, this position improperly narrows the application of the exeeption to those instances where a child sexual assault victim can reliably recount the details of the abuse at the time of the interview but has lost the capacity to do so by the time of trial. Nothing in the plain language of either the Rule or the Statute requires such a restrictive application of the child witness exception.
22 Instead, the legislature has indicated its contrary intent by, on two occasions, extending the reach of the child witness exception. While the initial version of the Statute applied only to children "under the age of ten," see Utah Code Ann. $ 76-5-411(8) (Supp.1983), within a few short years, the legislature modified the child witness exception to apply to children "under the age of 12," see id. (Supp. 1985); Utah Code Ann. § T7-85-15.5 (Supp.1986) (enacting the Rule, which was originally part of the Utah Code), and then further revised it to include children "under the age of 14," see Utah Code Ann. § 76-5-411(4) (Supp.1988); Utah Code Ann. § 77-85-15.5 (Supp.1988). Where the child witness exception now applies to victims approaching the age of fourteen years, it is apparent that many protected children are intelligent, articulate, and capable of aceu-rately recalling events long after they have occurred. Nevertheless, the legislature has extended the reach of the exception to protect these adolescents. 12
1283 Consistent with the language and rationale of the child witness exception, Stepdaughter was spared the burden of recounting the details of her experiences at trial by use of the videotaped interview. The trial court properly considered the reliability of Stepdaughter's out-of-court statement, entered appropriate findings and conclusions, and determined that the interest of justice would be served by allowing the State to show the redacted videotape to the jury. We hold that the trial court did not err by not making specific findings that the out-of-court statement was necessary or that it was not unduly cumulative or unfairly prejudicial. 13
II, Prosecutor's Statements
124 Next, Nguyen argues that the trial court erred in denying his motion for a mistrial because the prosecutor's statements characterizing Stepdaughter's testimony as "uncontested," "unimpeached," and "the only evidence" the jury had, improperly commented on Nguyen's invocation of his Fifth Amendment right to remain silent. 14 While
it is improper for either the court or the prosecutor to ask the jury to draw an adverse inference from a defendant's silence[,] ... the protective shield of the Fifth Amendment should {not] be converted into a sword that cuts back on the area of legitimate comment by the prosecutor on the weaknesses in the defense case.
*544
United States v. Robinson,
1 25 The Utah Supreme Court considered prosecutorial comments similar to those made by the prosecutor here in State v. Nelson-Waggoner,
[26 The supreme court affirmed the conviction, explaining,
A prosecutor has the duty and right to argue the case based on the "total picture shown by the evidence or the lack thereof," including reference to the paucity or absence of evidence adduced by the defense. But prosecutorial comment on a defendant's refusal to testify may violate a defendant's privilege against self-incrimination.
Id. 181 (quoting State v. Hales,
T27 Applying that standard, the Nelson-Waggoner court concluded that the following statements, and others like them, made during the prosecutor's closing argument did not cross that line: "[Nlo one has told you ... where the defendant was or what he was doing on the [day of the assault]. No one has told you, except for one person, and that is [the accuser]"; "[Nlobody knows where he is on the [day of the assault] exeept for [the accuser]"; "[The evidence you heard is clear . it is undisputed"; "[I)t's the truth because that's all the evidence you've heard. And, in fact, the defendant's brother and two friends took the stand ... and not onee did they say, [the accuser is] up in the night"; and "[The defendant's brother and his two good friends ... took the stand, they were here available, and not onee did they dispute that evidence." Id. €32 (omissions in original) (internal quotation marks omitted). The supreme court determined that "(individually and collectively, the State's comments constitute 'paucity' statements, and not comments on [the defendant's] silence," because they "provide examples of statements which may, but which must not 'naturaily' or 'necessarily, be interpreted as appeals to convict
*545
[the defendant] because he did not testify." Id. 188; see also State v. Tilt,
€28 The nature of the claims against the defendant in this case and in Nelson-Wag-goner, as well as the type and frequency of comments by each of the prosecutors, are similar. Both cases involve a charge of sexual misconduct where only the defendant and his accuser were witnesses to the challenged conduct. Likewise, the prosecutors in both cases made numerous references to the lack of evidence presented by the defense to refute the accuser's account. Specifically, Nguyen complains of the following statements by the prosecutor: "The only evidence that you have is the ... uncontested, unim-peached testimony of [Stepdaughter]"; "The only evidence you have is what [Stepdaughter] told you"; "[Slhe has been unim-peached"; "Not a single motivation has been raised to show why she would possibly lie in these cireumstances"; "There is the complete absence of any evidence of coaching"; "[There is a clomplete lack of any evidence of any motivation to lie in this case"; and "Completely unimpeached testimony of [Stepdaughter] that this particular event, aggravated sexual abuse of a child, ... took place about a week before Christmas of 2006." We can discern no appreciable difference between these comments and the statements of the prosecutor approved by the supreme court in Nelson-Waggoner.
129 Most of the prosecutor's statements regarding the lack of evidence in this case referred specifically to the failure of Nguyen's defense counsel to present evidence that Stepdaughter might have lied or that she might have been coached. These comments anticipated the suggestion during the defense's closing argument that Stepdaughter had several potential motivations to lie. It was appropriate for the prosecutor to highlight for the jury that the defense had presented no evidence supporting any of the alleged motivations. Some of the prosecutor's more general comments, including that Stepdaughter's testimony was "the only evidence" before the jury and that her testimony was "uncontested" may have reminded the jury that Nguyen did not testify. However, the prosecutor could properly comment on the "paucity or absence of evidence" presented by the defense to contradict Stepdaughter's testimony or to establish a motive for Stepdaughter to fabricate her allegations against Nguyen. See Nelson-Waggoner,
CONCLUSION
130 The child witness exception does not include a requirement that the trial court make a specific, separate finding of good cause or that the evidence was not unduly cumulative under the child witness exception. Therefore, the unchallenged factual findings support the trial court's conclusions that Stepdaughter's videotaped interview was re-Hable and that the interest of justice would best be served by its admission. Finally, the prosecutor did not violate Nguyen's constitutional right to remain silent by the comments 'he made in closing argument. 16

132 WE CONCUR: JAMES Z. DAVIS, Presiding Judge and STEPHEN L. ROTH, Judge.
Notes
. Although Nguyen and the child victim's mother were not married, they lived together for several years. We refer to the child as "Stepdaughter" to protect her identity and to avoid the use of initials for the convenience of the reader.
. The Statute was repealed by the legislature in 2009, see Utah Code Ann. § 76-5-411 (Supp. 2010), just after trial in this case. The Rule, which was rewritten effective November 1, 2008, see Utah R.Crim. P. 15.5 history (2010), is now the sole provision governing the admissibility of recorded statements by child victims of sexual abuse. References to the Rule throughout this opinion refer to the 2007 version in effect during Nguyen's trial unless otherwise indicated.
. The Fifth Amendment of the United States Constitution is applicable to the states through the Fourteenth Amendment. See State v. Hales,
. Because we agree with the State that Nguyen has not marshaled the evidence supporting the trial court's findings of fact, we limit our review to Nguyen's contention that the trial court used an incorrect legal standard in applying the child witness exception. See Ostermiller v. Ostermiller,
. While written findings are strongly recommended, "where the record as a whole sufficiently indicates that the comprehensive inquiries mandated by [the Statute] and [State v. Nelson,
. This statute has since been repealed. See supra note 2.
. Nguyen does not challenge the trial court's conclusion that the videotape of Stepdaughter's interview is reliable and trustworthy.
. Nguyen's definition of "good cause" as "a need for" the evidence is too restrictive. Many rules and statutes governing trial practice require "good cause shown," yet are not predicated only upon the special need for the relief sought or the information requested. See, e.g., Lafferty v. State,
. The determination that the child is "unavailable" was thought to be a legitimate justification for encroaching on the defendant's Fifth Amendment right of confrontation. See Julian v. State,
. The supreme court held that the videotaped interview of the brother was improperly admitted because the child witness exception then applied only to the child victim. See State v. Pecht,
. The State in Pecht did not argue that the videotaped interviews were also admissible under the Rule. However, the Statute incorporates the Rule by reference and seeks the same end, and both provisions must be met before a child's out-of[-court statement may be admitted. See State v.. Seale,
. The three minutes recorded by the videotape during which Stepdaughter cried so hard that she could not continue her detailed description of the abuse shows that even articulate, rational, and confident children, who are too old to be easily coached, can be profoundly affected by recounting their intact memories of sexual abuse.
. We note that the prejudicial impact of the videotaped interview was diminished by the State's restraint in not eliciting testimony that repeated the details of the individual incidents of abuse, by the trial court's refusal to allow the jury to watch the tape again during deliberations, and by the trial court's direction that the State redact the child's emotional breakdown from the version of the video played for the jury.
. Nguyen does not assert that the prosecutor's comments violated his state constitutional privilege against sell-incrimination. See Utah Const. art. I, § 12. Consequently, we do not address that issue. See State v. Nelson-Waggoner,
. Furthermore, the prosecutor's clarification on rebuttal that Nguyen was presumed innocent, had the right to remain silent, and had no duty to present any evidence in his defense went a long way toward dispelling whatever confusion may have been created by his original comments. These concepts were also contained in the trial court's initial instructions to the jury, and Nguyen rejected the trial court's offer to reiterate them in a corrective instruction.
. Because we find no error, we need not consider Nguyen's claim that he has been prejudiced by cumulative error.
