Opinion
FOTI, J.
The defendant, Ronald Vumback, Jr., appeals from the judgment of conviction, rendered after a trial to the court, of sexual assault in the first degree in violation General Statutes § 53a-70 (a) (1) and (2), attempt to commit to sexual assault in the first degree in violation of General Statutes §§ 53a-49 (a) (2) and 53a-70 (a) (1) and (2), sexual assault in the third degree in violation of General Statutes § 53a-72a (a) (1) (A) and risk of injury to a child in violation of General Statutes § 53-21. On appeal, the defendant challenges the trial court’s denial of his motion for a bill of particulars and the admission of certain evidence. We affirm the judgment of the trial court.
The court found the following facts. The victim lived with her divorced mother in Wallingford. The victim was six years old in 1990 when her mother met the defendant. In July, 1991, the defendant began living with the victim’s mother, the victim and her sister, and the victim’s grandmother. The victim’s mother and the defendant married in 1992 and had a child of their own in 1995.
From approximately June, 1990, through July, 1996, the defendant repeatedly sexually abused and attempted to sexually abuse the victim. The sexual abuse and attempted sexual abuse occurred in the family home. On July 11,1996, the victim’s mother took the [316]*316victim, who was then twelve years old, to a physician’s office for treatment of a vaginal rash. Mary Peterson, a certified nurse practitioner, saw the victim and preliminarily diagnosed that the rash was likely a manifestation of the herpes virus. On July 17, 1996, the results of a vaginal culture taken from the victim on July 11, 1996, confirmed Peterson’s preliminary diagnosis.
While in the physician’s office on July 17, 1996, the victim’s mother informed Peterson that it was the defendant who had transmitted the herpes virus to the victim.1 The victim explained to Peterson that the defendant had been sexually abusing her for the last six years. In response, Peterson contacted the department of children and families. The victim now resides with her biological father.
The state filed five separate informations. Each information stated that the defendant was accused of offenses against the victim and that such offenses occurred on “divers dates between approximately June, 1990, through July, 1996 . . . .” They further stated that the offenses occurred at the family home and listed the address of that residence. Subsequent to the state’s filing its last information, the defendant filed a motion for a bill of particulars, which the court denied. The defendant was subsequently found guilty of the charges against him, and this appeal followed. Additional facts will be set forth as necessary.
I
The defendant first claims that the court abused its discretion when it denied his motions for a bill of particulars and for a new trial because the charges against him lacked sufficient particularity. The defendant claims that this denial violated his due process right to [317]*317notice of the charges against him and that such denial prejudiced his defense. Specifically, the defendant asserts that the state’s failure to provide specific dates of the charged offenses violated his constitutional right to a fair trial. We are not persuaded.
“[T]he denial of a motion for a bill of particulars is within the sound discretion of the trial court and will be overturned only upon a clear showing of prejudice to the defendant. ... A defendant can gain nothing from [the claim that the pleadings are insufficient] without showing that he was in fact prejudiced in his defense on the merits and that substantial injustice was done to him because of the language of the information.” (Citation omitted; internal quotation marks omitted.) State v. Kyles, 221 Conn. 643, 653, 607 A.2d 355 (1992).
The defendant asks this court to determine whether the trial court’s denial of his motion for a bill of particulars, in the absence of specific dates in the state’s information, denied him his due process right to notice of the nature of the charges against him. In support of this claim, the defendant makes various overlapping assertions, but essentially argues that the state failed to apprise him of the nature of the charges against him because the state failed to provide the defendant with the “dates, times and places” of the offenses charged. The defendant further argues that the inexactness of the state’s allegations precluded him from presenting an alibi defense.
Our Supreme Court has held numerous times that “[t]he state has a duty to inform a defendant, within reasonable limits, of the time when the offense charged was alleged to have been committed. The state does not have a duty, however, to disclose information which the state does not have. Neither the sixth amendment [to] the United States constitution nor article first, § 8, of the Connecticut constitution requires that the state [318]*318choose a particular moment as the time of an offense when the best information available to the state is imprecise.” (Internal quotation marks omitted.) State v. Laracuente, 205 Conn. 515, 519, 534 A.2d 882 (1987), cert. denied, 485 U.S. 1036, 108 S. Ct. 1598, 99 L. Ed. 2d 913 (1988).
In State v. Blasius, 211 Conn. 455, 559 A.2d 1116 (1989), the state charged the defendant with sexual abuse that it alleged occurred over approximately a six month period. Our Supreme Court held that the state did not breach its duty to inform the defendant of the nature of the charges against him because the state did not know to a “reasonable certainty that the [offenses were] committed within a narrower time frame than that provided in the [information] . . . .” (Internal quotation marks omitted.) Id., 461.
In State v. Saraceno, 15 Conn. App. 222, 234—35, 545 A.2d 1116, cert. denied, 209 Conn. 823, 824, 552 A.2d 431, 432 (1988), the state, “to the best of its ability,” identified in a substitute information the time and date of when the charged offenses of sexual assault occurred. We held that “[t]he general rule in Connecticut is that [t]ime is not an essential ingredient of the crime of [sexual assault].” (Internal quotation marks omitted.) Id., 236. Furthermore, we noted that there was no evidence that the state knew the precise dates of the offenses and deliberately withheld them from the defendant. Id. Had that been the case, “the defendant’s claim . . . would [have been] more convincing.” (Internal quotation marks omitted.) Id.
In State v. Spigarolo, 210 Conn. 359, 363, 556 A.2d 112, cert. denied, 493 U.S. 933, 110 S. Ct. 322, 107 L. Ed. 2d 312 (1989), the information alleged that the defendant committed the crimes of sexual assault and risk of injury to a child between October, 1984, and January 3, 1985. Our Supreme Court noted that “[i]t [319]*319would have been virtually impossible to provide the many specific dates upon which the acts constituting the offenses occurred. . . . The reluctance of the court to force the state to furnish the exact dates of the many continuing acts of the defendant during the . . . period covered by the information and which were claimed, in toto, to have constituted [the charged offenses] was shown to be clearly reasonable by the testimony of the trial.”2 (Citation omitted; internal quotation marks omitted.) Id., 386-87.
In this case, the record shows that the state was merely aware of possible dates on which the offenses might have occurred, but that it chose not to plead them in its final information because those dates were unsubstantiated by the evidence. For example, the information filed on March 7, 2000, pinpointed a ten day window, from July 5 to 15, 1996, during which some of the offenses might have occurred. The final information, however, did not include those dates because, as the record demonstrates, the information was imprecise. Before ruling on the defendant’s motion for a bill of particulars, the court asked the assistant state’s attorney about his knowledge of specific dates. The assistant state’s attorney responded, “I cannot give the defendant anything I don’t have.” The record supports the assertion that the state did not have knowledge of the specific dates.
At trial, the victim’s testimony was inconsistent in various respects. The victim testified that she told Peterson that the defendant sexually assaulted her on July 3, 1996. Just moments later, she testified that she did not tell Peterson that she had been sexually assaulted on that date. The victim was otherwise unable [320]*320to pinpoint any specific dates throughout the six year time period ranging from June, 1990, to July, 1996. It is reasonable to conclude, on the basis of the record, that the state had imprecise information regarding the exact timing, or a narrower time frame, of the sexual assaults and necessarily omitted such dates from its final information.
The record reveals that the state’s best information regarding the exact times of the charged offenses was imprecise. On the basis of the information available to it, the state reasonably and to the best of its ability set forth the time period of the charged offenses.3 The state did not breach its duty to disclose information to the [321]*321defendant because it did not have such information. The court acted within its sound discretion when it denied the defendant’s motion for a bill of particulars. Because we reach this conclusion, we likewise conclude that the court’s ruling did not cause the defendant to suffer harm and that he is not entitled to a new trial.
In addition, the defendant asserts that he was impermissibly precluded from presenting an alibi defense by the state’s inability to provide exact dates of the offenses. Our Supreme Court has rejected this precise claim several times. See State v. Evans, 205 Conn. 528, 535, 534 A.2d 1159 (1987), cert. denied, 485 U.S. 988, 108 S. Ct. 1292, 99 L. Ed. 2d 502 (1988). “That a defendant may offer an alibi defense is a factor to be considered by the court in deciding whether to grant a motion [for a bill of particulars], but an alibi defense does not create a per se requirement that the state limit the times in the information more narrowly than the evidence available warrants.” (Internal quotation marks omitted.) State v. Spigarolo, supra, 210 Conn. 387. On the basis of Evans and our previous discussion in this opinion, we conclude that the defendant was not impermissibly precluded from presenting an alibi defense by the state’s inability to provide exact dates of the offenses.
II
The defendant next claims that the court improperly allowed into evidence detailed constancy of accusation testimony in violation of State v. Troupe, 237 Conn. 284, 677 A.2d 917 (1996) (en banc), and that such testimony caused him substantial prejudice. The defendant claims that the court improperly allowed constancy of accusation witnesses to testily as to the “specifics” of the victim’s complaint. We do not agree.
Because constancy of accusation testimony is evidentiary in nature, a trial court’s admission of such testimony will be reversed on appeal only where there has [322]*322been an abuse of discretion and a showing by the defendant that such abuse has caused him substantial prejudice or injustice. See State v. Beliveau, 237 Conn. 576, 592, 678 A.2d 924 (1996).
The defendant has asked this court to determine whether the testimony of the state’s constancy of accusation witnesses exceeded the boundaries of admissibility established by our Supreme Court in Troupe. He alleges that the court allowed into evidence the testimony of Peterson, the certified nurse practioner who had examined the victim; Christina King,4 the arresting officer from the Wallingford police department; Shelly Glaser, a social worker for the department of children and families; and the victim’s grandmother concerning the substantive details of the offenses charged, rather than for any permissible corroborative purpose.
Constancy of accusation testimony is deeply rooted in Connecticut common law. See State v. Rolon, 257 Conn. 156, 187, 777 A.2d 604 (2001); State v. Troupe, supra, 237 Conn. 294-97. In Troupe, our Supreme Court limited the common-law rule,5 holding that “a person to whom a sexual assault victim has reported the assault may testify only with respect to the fact and timing of the victim’s complaint; any testimony by the witness regarding the details surrounding the assault must be strictly limited to those necessary to associate the victim’s complaint with the pending charge, including, for example, the time and place of the attack or the identity of the alleged perpetrator. In all other respects, our current rules remain in effect. Thus, such evidence is admissible only to corroborate the victim’s testimony and not for substantive purposes.” State v. Troupe, supra, 304.
[323]*323Furthermore, “[i]n determining whether to permit [constancy of accusation] testimony, the trial court must balance the probative value of the evidence against any prejudice to the defendant. . . . [Constancy of accusation evidence is not admissible unless the victim has testified, and is subject to cross-examination, concerning the crime and the identity of the person or persons to whom the victim has reported the crime . . . .” (Citation omitted; internal quotation marks omitted.) State v. Torres, 60 Conn. App. 562, 573, 761 A.2d 766 (2000), cert. denied, 255 Conn. 925, 767 A.2d 100 (2001). Our Supreme Court has reaffirmed Troupe’s limitation on the admissibility of constancy of accusation testimony on several occasions. See State v. Rolon, supra, 257 Conn. 187; State v. Sullivan, 244 Conn. 640, 645, 712 A.2d 919 (1998); see also State v. Troupe, supra, 237 Conn. 297-98, 303-304; State v. Kelley, 229 Conn. 557, 565, 643 A.2d 854 (1994).
This court, as well, has reviewed numerous trial court decisions in light of Troupe. In State v. Orhan, 52 Conn. App. 231, 243, 726 A.2d 629 (1999), we held that “[t]he controlling language from Troupe does not limit the identifying information that may be provided. It limits only the extent of the information provided. Our Supreme Court merely gave examples of how a sexual assault might be identified; it did not hold that that was the only testimony that could be provided.” See State v. Barile, 54 Conn. App. 866, 872-73, 738 A.2d 709 (1999). In State v. Lisevick, 65 Conn. App. 493, 508, 783 A.2d 73, cert. denied, 258 Conn. 933, 785 A.2d 230 (2001), we recognized that “[o]ur Supreme Court did not limit the exact terms a constancy of accusation witness could use in her testimony.” Most recently, in State v. Williams, 65 Conn. App. 449, 465, 783 A.2d 53, cert. denied, 258 Conn. 927, 783 A.2d 1032 (2001), we were confronted with a defendant charged with various counts of sexual abuse based on various actions taken by the [324]*324defendant against the victim. We held that “[u]nder Troupe, the state is allowed to introduce any constancy of accusation testimony found necessary to associate the victim’s complaint with the pending charges.” Id. 464-65.
The defendant in this case was charged with various counts of sexual assault. The victim testified as to the details of those sexual assaults6 and as to the identities [325]*325of those to whom she reported such incidents. The state, thereafter, corroborated the victim’s testimony with the testimony of four additional witnesses.
Peterson’s testimony corroborated the victim’s testimony that the defendant tried to put his penis inside of her vagina after she came out of the shower. Peterson testified, over the defendant’s objection, that the victim told her that “two weeks prior to the [victim’s] visit [to her] office . . . [the victim] was getting out of the shower and . . . her stepfather approached her and attempted to put his penis in her and tried to kiss her.” Peterson’s testimony, therefore, supported the victim’s direct testimony and was permissible to corroborate that testimony.
[326]*326The court also heard Glaser’s testimony. Glaser testified, over the defendant’s objection, that the victim told her “she had been sexually molested in her vaginal area and her breasts by the defendant. [The victim] also explained oral sex performed by the defendant on her. [The victim] also explained that [the defendant] attempted to put his penis inside of her.” Like Peterson’s testimony, Glaser’s testimony supported the victim’s direct testimony and was permissible to corroborate the victim’s testimony on direct and cross-examination.
Additionally, King’s testimony further corroborated the victim’s direct testimony. King testified, over the defendant’s objection, that the victim complained that the defendant “had asked her to touch his penis . . . [and] had attempted to . . . perform oral sex on her and touch her breasts . . . [and that the defendant also] attemptfed] to put his penis between her legs.” King stated further that the victim told her that the sexual assaults usually “occurred when [the victim] was leaving the shower to go get her clothes.” King’s testimony, like that of Peterson and Glaser, was corroborative of the victim’s testimony on direct and cross-examination.
Finally, the court had the benefit of testimony from the victim’s grandmother. The grandmother testified, over the defendant’s objection, as to what she overheard the victim say to one of the victim’s friends while they were seated in the back of the grandmother’s car. She testified7 that she heard the victim say, “[The defendant] asked me to put his penis in [my] mouth . . . .”
The defendant argues that the court improperly admitted the testimony of the victim’s grandmother because it cannot be classified as constancy of accusa[327]*327tion testimony. He argues that testimony can qualify as constancy of accusation testimony only if it was elicited from a person to whom the victim intentionally and directly reported an alleged sexual assault. We recognize that our case law discusses such testimony in that context; see State v. Rolon, supra, 257 Conn. 187; State v. Troupe, supra, 237 Conn. 304; but we do not, however, read Troupe as creating such a defined limitation. On the basis of our reading of Troupe and its progeny, we conclude that the distinction that the defendant attempts to draw in this regard is of no consequence. The import of such constancy of accusation testimony is that the victim made prior allegations of abuse, not the identity of the person or persons to whom such statements were made. We decline, therefore, under the present circumstances, to hold that the court improperly admitted the testimony of the victim’s grandmother and we hold that it falls within the purview of constancy of accusation testimony. The court properly admitted the grandmother’s testimony because the grandmother heard from the victim’s mouth her statement of abuse and, thus, her testimony was constancy of accusation testimony, which served to corroborate the victim’s direct testimony.
After a careful review of the evidence, we conclude that the court properly admitted all of the challenged constancy of accusation testimony because such testimony corroborated the victim’s accusations and associated the defendant with the pending charges. The defendant has shown neither that the court abused its discretion in admitting the constancy of accusation testimony nor that he has been substantially prejudiced by the admission of such testimony. The court, therefore, acted within its sound discretion and did not exceed the limitations set forth in Troupe.
Ill
The defendant next claims that the court improperly permitted the state to elicit expert testimony without [328]*328requiring the state to make an adequate showing of reliability. The defendant argues that the court improperly concluded that the evidence satisfied the standard set forth in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 113 S. Ct. 2786, 125 L. Ed. 2d 469 (1993), as adopted by our Supreme Court in State v. Porter, 241 Conn. 57, 698 A.2d 739 (1997) (en banc), cert. denied, 523 U.S. 1058, 118 S. Ct. 1384, 140 L. Ed. 2d 645 (1998), and codified in the Connecticut Code of Evidence § 7-2, which requires a trial court to make a threshold inquiry into the admissibility of scientific evidence.8
Underlying the defendant’s claim is the presumption that the testimony of John Leventhal, professor of pediatrics at the Yale Medical School and attending pediatric physician at Yale-New Haven Hospital, constitutes “scientific evidence.” Specifically, the defendant argues that the state offered, and the court improperly admitted, Leventhal’s testimony to explain that victims of sexual abuse often lack precision in their allegations and to show the common factors regarding a victim’s delay in reporting sexual abuse. We are not persuaded.
We first note our standard of review. “[T]he trial court has broad discretion in ruling on the admissibility . . . of evidence. . . . The trial court’s ruling on evidentiary matters will be overturned only upon a showing of a [329]*329clear abuse of the court’s discretion. . . . We will make every reasonable presumption in favor of upholding the trial court’s ruling, and only upset it for a manifest abuse of discretion.” (Internal quotation marks omitted.) State v. Copas, 252 Conn. 318, 326, 746 A.2d 761 (2000).
The defendant has asked this court to determine whether the trial court properly concluded that Leventhal’s reasoning or methodology was scientifically valid. The defendant contends that Leventhal’s testimony was based on “nothing more than mere speculation” and, as such, fails to comport with the Daubert standard.
It is first necessary to determine whether such evidence is of the kind contemplated by Porter before subjecting it to the Daubert standard for admissibility. Stated differently, we must determine whether Leventhal’s challenged expert testimony qualifies as “ ‘scientific evidence.’ ” See State v. Reid, 254 Conn. 540, 546, 757 A.2d 482 (2000).
In Porter, our Supreme Court “explicitly adopted the Daubert test to determine the admissibility of scientific evidence . . . [but it] did not explicitly overrule Connecticut precedent regarding the evidence to which such a test should apply.”9 (Citation omitted.) Id.; see State v. Porter, supra, 241 Conn. 68; see also State v. Borrelli, 227 Conn. 153, 163, 629 A.2d 1105 (1993); State v. Hasan, 205 Conn. 485, 489, 534 A.2d 877 (1987). Courts apply the Daubert standard only when such testimony involves “innovative scientific techniques . . . .” (Internal quotation marks omitted.) State v. Reid, supra, 254 Conn. 546. To determine if such a technique exists, we look to see whether the trier of fact is “in a position to weigh the probative value of [330]*330the testimony without abandoning common sense and sacrificing independent judgment to the expert’s assertions based on his special skill or knowledge.” (Internal quotation marks omitted.) Id., 547, quoting State v. Hasan, supra, 491. Furthermore, we determine if the testimony is based on obscure scientific theories that have the “potential to mislead [the trier of fact] awed by an aura of mystic infallibility surrounding scientific techniques, experts and the fancy devices employed.” (Internal quotation marks omitted.) State v. Hasan, supra, 490. If an expert’s testimony concerns a method, “the understanding of which is accessible to the [trier of fact] . . . and the value of the expertise lay in its assistance to the [trier of fact] in viewing and evaluating the evidence,” the testimony is not scientific even though an expert’s skill and training are based on science. (Citation omitted; internal quotation marks omitted.) State v. Reid, supra, 547;10 see State v. Hasan supra, 491.
On the basis of our review of relevant case law, Leventhai’s testimony did not rise to the level of scientific evidence. We recognize that no appellate court in this state has held that the technique for evaluating the behavior of sexually abused children is not “scientific evidence.” In Borrelli, however, our Supreme Court held that expert testimony concerning battered wom[331]*331an’s syndrome was not scientific because it was based on the expert’s “observations of a large number of battered women through the lens of his educational background and experience” and that the purpose of the testimony was “to provide an interpretation of the facts.” State v. Borrelli, 227 Conn. 165.
Further examination of Leventhal’s testimony reveals that it was very similar to the nonscientific expert testimony admitted in Borrelli. Like the expert in Borrelli, Leventhal did not personally examine the victim. Although he formed a personal opinion as to the defendant’s ultimate guilt and testified that there were signs that the victim had herpes before she was diagnosed, he did not offer any opinion as to whether the victim in fact had been sexually abused. Leventhal “did not apply any scientific instrument or test to specific evidence in the case” and he “did not apply any scientific test to a hypothetical question posed by the state.” Id., 164-65.
Leventhal merely explained, on the basis of his experience and education, how children subjected to sexual abuse might act under certain circumstances. Additionally, his method of studying and comparing the allegations of numerous child victims of sexual abuse based on his education and experience was accessible to the court, and the value of his testimony was rooted in its assistance to the court in viewing and evaluating the evidence.
We find, on the basis of the circumstances of this case, that the court was in a position to weigh the probative value of the testimony without abandoning common sense and sacrificing independent judgment to the expert’s assertions based on his special skill or knowledge, and that this evidence was not based on obscure scientific theories that were potentially misleading to the trier of fact. We conclude, therefore, that, [332]*332like the testimony in Borrelli, Leventhal’s testimony was not scientific. As a result, the court was not required to determine whether his testimony satisfied the Daubert standard for admissibility. Because we conclude that Leventhal’s testimony was not scientific, the court acted within its sound discretion in admitting his testimony.
IV
The defendant’s final claim is that the court’s evidentiary errors deprived him of a fair trial. The defendant claims that the court’s admission of constancy of accusation testimony, coupled with Leventhal’s expert testimony, constituted reversible, cumulative evidentiary error. Specifically, he argues that the court allowed the state’s constancy of accusation witnesses to testify “mechanically” and “repeatedly” as to the details of the victim’s allegations, and that Leventhal’s testimony was speculative. We do not agree.
Because we have concluded that the trial court properly admitted the challenged constancy of accusation testimony, along with Leventhal’s expert testimony, no error exists.
The judgment is affirmed.
In this opinion O’CONNELL, J., concurred.
