Virgil McCoy appeals his May 2, 1985, conviction of second degree sexual assault, W.Va.Code § 61-8B-4 (1984), following a jury trial in Cabell County. Because we find that the lower court erred in admitting certain expert testimony, we reverse and remand for a new trial. 1
On September 10, 1984, Virgil McCoy was drinking beer with his brother and cousin at a tavern on the west side of Huntington. While he was there, Anneta Dawn Booth, the alleged victim in this case, entered with a friend, Patsy Jean Roy. McCoy and Booth knew one another through Booth’s friendship with McCoy’s wife, who at that time was separated from McCoy. After the five drank a round of beer, the two women left to go to a second tavern, the Valhalla. McCoy and his companions joined Booth and Roy there.
Booth agreed to give McCoy a ride home, and Booth, McCoy, and Roy left the Valhalla at approximately 4:00 a.m. on September 11, 1984. After dropping Roy off at her apartment, Booth drove to a nearby car wash, where she did figure eights around the vacuum pumps. Then, either McCoy or Booth put the car in park, and Booth and McCoy talked and kissed. McCoy testified that this was a voluntary act. Booth testified, however, that McCoy forced himself on her despite her complaints and continued directions to stop. McCoy eventually stopped and apologized, and Booth took him to his residence. Booth then went home.
At approximately 9:30 a.m. on September 11, 1984, McCoy knocked at Booth’s door and invited himself in for coffee. Booth was wearing a short wrap-around robe. *225 After McCoy finished his coffee, he and Booth went into the bedroom and engaged in sexual intercourse, with Booth in the top position. At trial McCoy denied that he used force during the act and testified that Booth did not ask him to stop. Booth, however, testified that McCoy pulled her into the bedroom, pushed her down on the bed, removed her clothes, then flipped her on top of him and forced her to have intercourse. Booth testified that she screamed and begged him to stop, but did not bite him and did not recall leaving any scratch marks on him.
After McCoy left her home, Booth testified that she showered and went to her sister’s (Monica Booth’s) residence. Monica Booth testified that her sister’s face was swollen and bruised. Monica Booth also testified that she observed red marks on Booth’s breasts. Booth did not relate to her sister what had happened.
Later that day, at approximately 6:00 p.m., Booth told a friend, Roger Johnson, that she had been sexually assaulted by McCoy. Then at approximately 12:30 a.m. on September 12, 1984, Booth told her boyfriend, Ronnie Grobe, of the incident. Grobe, a police officer, persuaded Booth to tell the police, and at approximately 3:00 a.m. on September 12, 1984, Booth filed a report with the Huntington Police Department. Booth was interviewed by Detective Darrell Black, who testified that he observed abrasions on Booth’s lower lip and small bruises under her left ear. Detective Black also testified that Booth appeared very emotional and very upset. On November 19, 1984, the Cabell County Grand Jury returned an indictment against Virgil McCoy charging him with Second Degree Sexual Assault, W.Va.Code § 61-8B-4 (1984).
The trial began on April 24, 1985. On the second day of the trial, the prosecution called Lauren McKeown as an expert witness. After hearing her qualifications, the trial court granted the prosecution’s motion that McKeown be qualified as an expert to give an opinion “as to the victim’s reactions subsequent to the alleged assault.” McKeown testified about common behavior of rape victims, and gave her opinion about whether Booth’s actions after the incident conformed with typical post-rape behavior.
I.
McCoy argues first that the lower court erred in finding that McKeown was qualified as an expert to testify about the behavior of rape victims. Rule 702 of the West Virginia Rules of Evidence governs testimony by experts. Rule 702 provides:
If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education may testify thereto in the form of an opinion or otherwise.
McKeown was, at the time of trial, assistant director of the Branches Domestic Violence Shelter in Huntington, West Virginia, a shelter for battered women and children. She was also co-founder and coordinator of the Rape Crisis Counseling Team, which assists sexual assault victims. McKeown held a bachelor’s degree in sociology and a master’s degree in community agency counseling. She had received training in rape crisis counseling and had worked previously for the Rape Victim Companion Program in Winchester, Virginia, and with the Women’s Center at Marshall University in Huntington, West Virginia, dealing with sexual assault victims. She had attended conferences on the subject and read current literature. She had experience with over one hundred cases of sexual assault or sexual abuse. We find that McKeown had sufficient knowledge, training, and experience to qualify under Rule 702 as an expert in the rape counseling area and that the trial court did not err in so ruling.
II.
Over the objections of McCoy’s lawyer, McKeown testified about Booth’s behavior subsequent to the alleged assault. McKeown concluded that Booth’s behavior subsequent to the alleged assault, including her delay in telling anyone and the *226 taking of several showers after the incident, were in conformity with that of someone who had been sexually assaulted. McKeown concluded further that Booth was “still traumatized by this experience.” 2
We have not had an occasion to consider the admissibility of expert testimony on post-rape behavior. Such behavior is often referred to as “rape trauma syndrome,” a term coined in 1974 to describe certain physical and emotional symptoms experienced by rape victims. See Burgess & Holmstrom, Rape Trauma Syndrome, 131 Am.J. Psychiatry 981 (1974). 3 Burgess and Holmstrom describe rape trauma syndrome as an acute stress reaction to a life-threatening situation, usually occurring as a two-phase reaction. During the first phase, the acute phase, the victim experiences a great deal of disorganization in her life-style. The acute phase is characterized by certain physical and emotional reactions, including fear, humiliation, anger, revenge, and self-blame. The acute phase is followed by the “long-term process” or “reorganization phase,” characterized by tendencies to change residences and telephone numbers and to turn to family members for support. 4
In her testimony describing behavior characteristic of sexual assault victims, McKeown did not use the term “rape trauma syndrome” or discuss it as described by Burgess and Holmstrom. We, however, realize that admissibility of expert testimony on post-rape behavior should not necessarily turn on whether or not the expert uses the term “rape trauma syndrome.”
See State v. Black,
Courts that have considered the issue disagree as to the admissibility of expert testimony on rape trauma syndrome or on post-rape behavior generally in a rape prosecution where consent is the issue. One of the first courts to consider this issue was the Supreme Court of Kansas in
State v. Marks,
Questioning the scientific reliability of rape trauma syndrome, in
State v. Salda
*227
na,
Similarly, in
State v. Taylor,
[t]he jury could determine whether the intercourse was forcible based on its own evaluation of the physical evidence and testimony and credibility of the witnesses. There is a risk that the jury will regard the expert’s opinion that a victim suffers from rape trauma syndrome resulting from forcible assault as disposi-tive on the issue of consent.
Id. at 241. The Taylor court, therefore, concluded that under the circumstances of that case, the expert “went too far in expressing his opinion that the victim suffered rape trauma syndrome as a consequence of the incident with the defen-dant_” Id. at 241. The court went on to say that:
[ujnder the qualifications given, the most that [the psychiatrist] could legitimately state would be that the prosecutrix’ symptoms were consistent with a traumatic experience — even a stressful sexual experience. But it goes beyond his qualifications to say that she was raped by defendant at Mary’s Moonlight Lounge. That’s indeed a chasm too wide and deep to leap.
Id.
at 241. Following the lead of
Taylor
and
Saldana,
in
People v. Bledsoe,
Citing
Saldana, Taylor,
and
Bledsoe,
in
State v. McQuillen,
The expert’s testimony was limited in scope. She testified concerning the reactions of rape victims generally; none of her testimony concerned this particular victim. She did not interview or contact the victim and did not testify that the victim suffered from rape trauma syndrome or that the victim had been raped. Nor did she express an opinion as to the truthfulness of the victim.
Id. at 961.
The common thread running through
Saldana, Taylor, Bledsoe, McQuillen,
and
Hampton
is that expert testimony on rape trauma syndrome is not admissible to show whether or not the complainant was, in fact, raped. The danger involved in permitting an expert to conclude that because a complainant suffers from rape trauma syndrome, the complainant was, therefore, raped is that “[such a] conclusion vouches too much for the victim’s credibility and supplies verisimilitude for her on the critical issue of whether defendant did rape her.”
Taylor,
[permitting a person in the role of an expert to suggest that because the complainant exhibits some of the symptoms of rape trauma syndrome, the complainant was therefore raped unfairly prejudices the appellant by creating an aura of special reliability and trustworthiness.
Saldana,
Having reviewed decisions from the courts which have considered the admissibility of rape trauma syndrome testimony, we now turn to the case before us. Expert testimony that helps the jury to understand the evidence or determine a fact in issue is admissible under W.Va. Rule Evid. 702.
9
We agree with the Supreme Court of Kansas that in a prosecution for rape where
*229
consent is the defense, qualified expert testimony regarding the existence of symptoms consistent with rape trauma syndrome is relevant and admissible.
See
syl. pt. 4,
State v. McQuillen,
When McKeown took the stand as an expert, she did not limit her testimony to the behavior of sexual assault victims, generally. Nor did she limit her testimony to an opinion that Booth’s behavior was in conformity with behavior of others she had treated as victims of sexual assault. Rather, McKeown concluded that Booth was “still traumatized by this experience.” Her reference to
this
experience was tantamount to an opinion that Booth had, in fact, been raped by the defendant. Her testimony amounted to a statement that she believed the alleged victim, and by virtue of her expert status she was in a position to help the jury determine the credibility of the most important witness in a rape prosecution. McKeown’s conclusion that she believed that Booth had been raped “encroach[ed] too far upon the exclusive province of the jury to weigh the credibility of the witnesses and determine the truthfulness of their testimony,”
McQuillen,
A further problem in this case is the credibility of the expert. Her testimony was based on two interviews with the alleged victim, both occurring on the eve of trial, when considerable time had passed since the incident. Where the expert has no immediate contact with the victim of an alleged rape, it is possible for the victim to fabricate post-rape behaviors consistent with rape trauma syndrome. Under these circumstances, McKeown’s testimony had the potential to confuse and mislead the jury in making a factual determination as to whether Booth was raped. The lay jurors were capable of determining, based on the other evidence presented, whether they believed Booth was raped.
11
In this regard we note that admissibility of expert testimony depends, in each case, on the particular evidence offered, and evidence which is misleading or confusing should be excluded.
12
“Under W.Va.R.Evid. 702, a trial
*230
judge has broad discretion to decide whether expert testimony should be admitted, and where the evidence is unnecessary, cumulative, confusing or misleading the trial judge may properly refuse to admit it.” Syl. pt. 4,
Rozas v. Rozas,
For the foregoing reasons, we reverse the judgment of the Circuit Court of Cabell County and remand for a new trial.
Reversed and remanded.
Notes
. Other errors raised by the appellant are without merit, and we do not address them in this opinion.
. McKeown testified in part as follows:
Mr. Hatcher: In your talking to the victim in this case, do you in your opinion feel that she is still traumatized by this experience?
Mr. Means: I object.
The Court: Overruled.
McKeown: Yes.
Record at 215-16.
At the time of her testimony, McKeown had met with Booth on two occasions. McKeown spoke with Booth for the first time on the day before trial and again on the day of McKeown’s testimony. McKeown had not reviewed the statement Booth had given to the police within forty-eight hours of the alleged assault.
. See generally McCord, The Admissibility of Expert Testimony regarding Rape Trauma Syndrome in Rape Prosecutions, 26 B.C.L.Rev. 1143, 1144-48 (1985).
. Rape trauma syndrome is not mentioned as a diagnostic entry in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (3d ed. 1980) (DSM-III), a widely recognized reference for diagnosing mental disorders. The American Psychiatric Association recognizes rape as only one potential cause of Post-traumatic Stress Disorder. See DSM-III at 236. "The essential feature [of Post-traumatic Stress Disorder] is the development of characteristic symptoms following a psychologically traumatic event that is generally outside the range of usual human experience.” Id. Other potential causes of Post-traumatic Stress Disorder include car accidents, airplane crashes, floods, earthquakes, military combat and torture. Id. See generally Buchele & Buchele, Legal and Psychological Issues in the Use of Expert Testimony on Rape Trauma Syndrome, 25 Washburn L.J. 26 (1985).
. Accord State v. Huey,
Psychiatric testimony is admissible to aid a jury in determining whether there was consent to engage in a sexual act which all parties agreed occurred. It remains up to the jury to determine whether the evidence is credible.
Id. at 923.
.
Accord State v. Black,
. The Bledsoe court added:
Even when the expert stops short of expressing an opinion on the ultimate issue of whether the complaining witness was raped and, as here, states simply that the witness is suffering from “rape trauma syndrome,” the use of this terminology is likely to mislead the *228 jury into inferring that such a classification reflects a scientific judgment that the witness was, in fact, raped.
Bledsoe,
.
Accord State v. Brodniak,
Mont.,
. We recognize that some jurisdictions have employed the test for admission of expert scientific testimony set forth in
Frye v. United States,
[Wjhile the courts will go a long way in admitting expert testimony deduced from a well-recognized scientific principle or discovery, the thing from which the deduction is made must be sufficiently established to have gained general acceptance in the particular field in which it belongs.
Frye,
The Frye court was concerned with the admission of the results of a systolic blood pressure deception test. Generally, the Frye test is applied to novel scientific devices and processes involving the manipulation of physical evidence including lie detectors, experimental systems of blood typing, voice prints, identification of human bite marks, and microscopic analysis of gunshot residue.
Hampton,
. We realize that the line drawn between admissible and inadmissible testimony is a fine one, and we therefore encourage trial courts to guard jealously the province of the jury by way of admonition to counsel and witnesses, cautionary instructions to the jury, etc.
. Prior to McKeown’s testimony, the jury heard testimony from Booth, her friends and relatives, and a police officer as to both the alleged victim’s physical condition and emotional behavior subsequent to the incident.
. We note that at least one court has limited admission of rape trauma syndrome evidence to testimony from a psychiatrist.
