OPINION
The primary issue in this case is whether, and under what circumstances, the “discovery rule” should apply to delay commencement of the statute of limitations period when a plaintiffs claims are based on repressed memories of childhood sexual abuse. Concluding that such claims by plaintifl/appellant Kim Logerquist were time-barred, the trial court granted summary judgment for defendants/appellees. Plaintiff appeals from that judgment and from the trial court’s subsequent denial of her motion for new trial. For the reasons stated below, we reverse and remand.
FACTS AND PROCEDURAL HISTORY
Plaintiff was born on August 27, 1962. Defendant John Danforth, M.D. is a pediatrician who has practiced in Mesa, Arizona since 1965. Danforth saw plaintiff on four office visits between 1971 and 1973, when plaintiff was eight and ten years old: twice for an ear infection, once for a urinary tract infection and once for a rash. Plaintiff claims that Danforth sexually molested her during those visits. She also alleges that she first remembered these events sometime in September 1991 and that until that time she “unconsciously blocked and/or repressed the memories of said assaults in order to survive emotionally.” In her deposition plaintiff testified that although she was unsure what triggered the memories, they occurred spontaneously when she was watching an old movie on television in September 1991. In the fall of 1991, plaintiff told two friends that her memories first surfaced while she was watching a commercial for children’s medicine in which a pediatrician appeared.
Plaintiff has three distinct memories which underlie her present claims. On each occasion plaintiff was completely undressed and alone with Danforth in an examination room. *18 In one memory, Danforth asks plaintiffs mother to leave the room. In the first memory, plaintiff recalls Danforth touching her inappropriately between the legs and inserting something cold into her vagina. In the second memory, plaintiff remembers feeling something inserted into her vagina and rectum and Danforth, after pulling out a large syringe, threatening to give her a big shot if she does not stop fussing. In the third memory, she remembers moving backwards on the table, feeling something inserted in her rectum and vagina, and being pulled down onto the table. 1 Plaintiffs mother, who accompanied her to Danforth’s office on three of the four visits, died in 1980. Danforth has denied plaintiffs allegations.
Plaintiff filed this action in September 1992, alleging various intentional torts, malpractice and breach of fiduciary duty. After the parties conducted considerable discovery, Danforth moved for summary judgment, primarily contending that plaintiffs claims were time-barred. 2 The trial court granted the motion and later denied plaintiffs motion for new trial. This appeal followed.
STANDARD OF REVIEW
In reviewing the granting of summary judgment on statute of limitations grounds, we view the evidence in a light most favorable to the party against whom summary judgment was entered and independently review any questions of law relating to the statute of limitations defense.
Owens v. City of Phoenix,
DISCUSSION
Our supreme court has explained the rationale underlying the statute of limitations as
primarily for the protection of the defendant, and the courts, from litigation of stale claims where plaintiffs have slept on their rights and evidence may have been lost or witnesses’ memories faded. This policy is sound and necessary for the orderly administration of justice. However, this policy may be outweighed “where the interests of justice require vindication of the plaintiffs rights.”
Brooks v. Southern Pacific Co.,
In determining whether a particular claim is time-barred, four factors must be examined: “(1) when did the plaintiffs cause of action accrue; (2) what is the applicable statute of limitations period; (3) when did the plaintiff file his [or her] claim; and (4) was the running of the limitations period suspended or tolled for any reason?”
Taylor v. State Farm Mut. Auto. Ins. Co.,
A personal injury action such as this must be “commenced and prosecuted within two years after the cause of action accrues, and not afterward.” A.R.S. § 12-542. Due to plaintiffs minority status at the time of the *19 alleged torts, the two-year limitations period normally would begin to run on her eighteenth birthday. A.R.S. § 12-502(A). Thus, unless the statute of limitations was tolled or otherwise extended, plaintiff was required to file suit by no later than August 27, 1982. She filed this action on September 11, 1992.
A. UNSOUND MIND
Plaintiff contends that her claims are tolled, and therefore not time-barred, because she was of “unsound mind” under A.R.S. § 12-502(A) (1992).
3
“Unsound mind” means that a person is “unable to manage his affairs or to understand his legal rights or liabilities.”
Allen v. Powell’s Int'l, Inc.,
The focus of the unsound mind inquiry is on a plaintiffs ability to manage his or her ordinary daily affairs. It does not focus on the plaintiffs ability to pursue the subject matter of the litigation at issue.
Id.,
Similarly, plaintiff presented insufficient evidence in this case to support a finding that she was incapable of managing her daily affairs or of understanding the nature of her legal rights. She has pursued an education in nursing and has held jobs in the health care field. Repressed memory due to childhood sexual abuse is an insufficient basis in itself for concluding that she was of “unsound mind,” and therefore the limitations period was not tolled under § 12-502(A).
See Lovelace v. Keohane,
B. DISCOVERY RULE
Plaintiff alternatively contends that she timely filed this action because her claim did not accrue until September 1991. Determination of a claim’s accrual date may implicate the so-called “discovery rule.” That common law rule, if sufficient evidence supporting its application is presented, may delay commencement of the time period within which suit must be filed. Under the discovery rule, a cause of action accrues “when the plaintiff knew or by the exercise of reasonable diligence should have known of the defendants’ conduct and therefore the statute of limitations does not begin to run until that time.”
Mayer v. Good Samaritan Hosp.,
The burden of establishing that the discovery rule applies to delay the statute of limitations rested on plaintiff.
Ulibarri v. Gerstenberger,
Arizona courts have applied the discovery rule to claims of malpractice,
Kenyon v. Hammer,
In holding that the statute of limitations did not bar the plaintiffs claim, the court in
Ulibarri
relied on cases based on insanity and duress,
Meiers-Post v. Schafer,
[W]hen the plaintiff presents evidence that the defendant concealed a cause of action thereby preventing the plaintiff from timely filing the claim, and when the defendant admits the actions underlying the claim thereby reducing the risk of staleness, the question of whether there is wrongful concealment capable of tolling the statute of limitations cannot be resolved by summary judgment.
Division One of this court also recently held “that the discovery rule applies to eases of repressed memory alleged to arise from childhood sexual abuse.”
Doe v. Roe,
Assuming the trial court determines that evidence of the underlying claim of repressed memory is admissible
(see
section (C),
infra),
we agree with the decision in
*21
Doe
to the extent it held that a plaintiff who allegedly was sexually abused as a child but during minority repressed all memories of the abuse until adulthood should have an opportunity to invoke the discovery rule. A number of other courts have reached that conclusion.
See, e.g., Hewczuk v. Sambor,
Courts adopting the discovery rule have emphasized the unfairness of requiring plaintiffs to sue at a time when their injury was not apparent and they could not reasonably have known about it.
E.g., Farris,
To rule that a child of tender years who is sexually abused, but promptly “forgets” the trauma and is not conscious of the wrong until the curtain of repression is lifted later in life, is barred as a matter of law from claiming damages because of the two-year statute of limitations, would be to declare that, in virtually all eases involving sexual abuse of young children committed in secret and not discovered by others at the time, the wrongdoer would be immunized from both criminal and civil consequences.
Hewczuk v. Sambor,
Ulibarri
imposed two requirements for invoking the discovery rule in cases such as this: the defendant must have wrongfully concealed the claim, and the plaintiff must provide some evidence corroborating that the alleged events occurred.
Ulibarri,
1. Concealment
Under
Ulibarri,
“[t]he wrongful concealment sufficient to toll a statute of limitations requires a positive act by the defendant taken for the purpose of preventing detection of the cause of action.”
A defendant’s wrongful concealment of facts preventing the plaintiff from detecting the wrongful act is a separate and distinct theory for tolling the statute of limitations.
See, e.g., Cooney,
2. Corroboration
The court in
Doe
did not address
Ulibarri’s
corroboration requirement. Most courts which have applied the discovery rule to cases involving repressed memory of childhood sexual abuse have not required corroboration. As the New Hampshire Supreme Court stated: “[W]e have not established the requirement of independent corroboration for other potential applications of the common law discovery rule.”
McCollum,
Our supreme court in Florez clearly stated the dilemma posed here:
Child sexual abuse eases present very difficult problems because of the competing interests at stake. The acts alleged are awful. They would arouse the righteous indignation of any sensible person. On the other hand, statutes of limitations are designed to encourage plaintiffs to pursue claims diligently and to prevent the assertion of stale and fraudulent claims.
We recognize that some courts have struck a balance between the competing interests by conditioning the application of the delayed discovery rule in cases involving repressed memory of childhood sexual abuse on a showing of some evidence corroborating the claims.
See, e.g., Petersen v. Bruen,
In Arizona, however, the statute of limitations defense is not favored,
Gust, Rosenfeld,
In this case, plaintiff claims that Dr. Danforth sexually abused her during childhood and, because of a totally repressed memory, she neither knew nor should have known of the abuse until 1991. She presented evidence, including expert testimony, supporting her claims. Danforth denies the allegations. This is a classic factual dispute involving credibility and memory issues for which summary judgment is inappropriate. 7 Relevant considerations bearing on the factual issues may include whether Danforth concealed his alleged acts, whether there is any evidence corroborating plaintiffs claims, whether repressed memory syndrome is a recognized and legitimate phenomenon and, if so, whether plaintiff genuinely had repressed memory. If the trier of fact concludes from the evidence that plaintiff knew or reasonably should have known of the alleged abuse more than two years before she filed suit, then her claim is time-barred.
In our view, selectively engrafting a corroboration requirement on the discovery rule’s application only in this type of case makes little sense and would amount to unwarranted judicial fiat.

Whether the discovery rule in this context should be conditioned on evidence of concealment or corroboration is a policy decision best left to the legislature.

C. ADMISSIBILITY OF REPRESSED MEMORY EVIDENCE
Defendants contend, as they did in the trial court, that plaintiffs repressed memory claim is based on experimental and questionable theories which have not been generally accepted by the scientific community. Therefore, according to defendants, any evidence of repressed memory is inadmissible under
Frye v. United States,
Notes
. Plaintiff assumes, but does not know, that Dan-forth inserted some kind of instrument into her in the first and second memories. In all of plaintiff's memories, Danforth was fully dressed and never exposed his penis.
. Danforth also argued that plaintiff's evidence was too speculative to present to a jury and that theories regarding repressed memory were not generally accepted in the scientific community.
. The statute provides that "[i]f a person entitled to bring an action ... is at the time the cause of action accrues ... of unsound mind, the period of such disability shall not be deemed a portion of the period limited for commencement of the action." A.R.S. § 12-502(A).
. Our supreme court in
Florez
distinguished
Ulibarri
and did not determine whether it was correctly decided. The court noted, however, that
Ulibarri
merged "such doctrines as equity, a 'delayed discovery rule,’ and concealment” and "appears to be based upon an unprecedented amalgamation of a variety of different theories.”
