LEVIN H. CAMPBELL, Senior Circuit Judge.

The mother and grandparents of two minor children brought this action in the district court under 42 U.S.C. § 1983 and state law against a social worker and two psychologists who were involved in the State of New Hampshire's investigation into reports that the children had been sexually abused. The two psychologists moved to dismiss the complaint against themselves, and the court allowed their motion. It ruled that they had absolute immunity from suit under 42 U.S.C. § 1983 and state statutory immunity from the pendent state law claims. We affirm, although on somewhat different grounds as to the § 1983 claims.

I.

In considering a motion to dismiss, a court must take the allegations in the complaint as true and must make all reasonable inferences in favor of the plaintiffs. Monahan v. Dorchester Counseling Ctr., Inc., 961 F.2d 987, 988 (1st Cir. 1992). Here the district court also took into account certain facts set out in public documents plaintiffs attached to an opposition they filed to the motion to dismiss. Ordinarily, of course, any consideration of documents not attached to the complaint, or not expressly incorporated therein, is forbidden, unless the proceeding is properly converted into one for summary judgment under Rule 56. See Fed.R.Civ.P. 12(b)(6). However, courts have made narrow exceptions for documents the authenticity of which are not disputed by the parties; for official public records; for documents central to plaintiffs' claim; or for documents sufficiently referred to in the complaint. See, e.g., Romani v. Shearson Lehman Hutton, 929 F.2d 875, 879 n. 3 (1st Cir. 1991) (considering offering documents submitted by defendants with motion to dismiss claim of securities fraud); Fudge v. Penthouse Int'l, Ltd., 840 F.2d 1012, 1014-15 (1st Cir.) (considering allegedly libelous article submitted by defendants with motion to dismiss), cert. denied, 488 U.S. 821, 109 S.Ct. 65, 102 L.Ed.2d 42 (1988); Mack v. South Bay Beer Distrib., Inc., 798 F.2d 1279, 1282 (9th Cir. 1986) ("[O]n a motion to dismiss a court may properly look beyond the complaint to matters of public record and doing so does not convert a Rule 12(b)(6) motion to one for summary judgment."); see also In re Wade, 969 F.2d 241, 249 n. 12 (7th Cir. 1992).

Here, all or most of the above-mentioned elements are present. Plaintiffs, moreover, introduced the documents themselves, in order to bolster their argument against defendants' motions to dismiss. See Cortec Indus., Inc. v. Sum Holding L.P., 949 F.2d 42, 48 (2d Cir. 1991) ("[T]he problem that arises when a court reviews statements extraneous to a complaint generally is the lack of notice to the plaintiff. . . . Where plaintiff has actual notice . . . and has relied upon these documents in framing the complaint the necessity of translating a Rule 12(b)(6) motion into one under Rule 56 is largely dissipated."), cert. denied, ___ U.S. ___, 112 S.Ct. 1561, 118 L.Ed.2d 208 (1992); Berk v. Ascott Inv. Corp., 759 F. Supp. 245, 249 (E.D.Pa. 1991) ("[W]hen a plaintiff has admitted the authenticity of a document . . ., a court may consider that document in ruling on a motion under Fed.R.Civ.P. 12(b)(6).").

Like the court below, therefore, we treat the documents submitted by plaintiffs — the Abuse and Neglect Petitions, the Pittsfield District Court orders, defendant Seymour's written report to defendant Page, and Seymour's affidavit — as part of the pleadings. The facts that emerge are as follows:

Plaintiff-appellant Valerie Watterson is the natural mother of two minor girls born in 1979 and 1984 respectively ("the older child" and "the young child"; collectively "the children" or "the girls"). Plaintiff-appellant Violet Bruillard is the natural mother of Valerie and grandmother of the children. Plaintiff-appellant Paul Bruillard is Violet's husband, and stepgrandfather to the children. The girls lived with all three appellants in a house belonging to Violet and Paul in New Hampshire. The girls' natural father, who separated from Valerie in 1981, is not a party to this action.

Since birth, the older child has had only partial hearing and partial speech abilities. Beginning in 1985, when she was six years old, the child attended the Green Acres School in Manchester, New Hampshire, as part of a program for the hearing impaired. In January 1986, school officials reported unusual behavior by the child to the New Hampshire Division for Children and Youth Services (DCYS), including symptoms of neglect and possible sexual abuse. DCYS officials investigated the case and identified a fourteen-year-old boy who rode to school on the child's school bus as the probable abuser. Steps were taken to remedy the situation and the case was closed.

In March 1987, however, school officials again wrote to DCYS to report continuing symptoms of sexual abuse. Defendant Eileen Page (who is not an appellee), a state social worker assigned to the case by DCYS, filed a Petition for Neglect in the Pittsfield District Court, State of New Hampshire, on May 18, 1987. See N.H.Rev.Stat.Ann. § 169-C:7. The petition alleged that the older child was subject to neglect by Valerie Watterson, citing the reports of the Green Acres School officials that the child was describing sexual matters in detail to other children and her teacher, fondling herself and other children, and complaining about pains in her stomach and lower abdomen. The petition also alleged that the child wore dirty clothing to school, was unkempt and unwashed, and appeared to be making her own lunch of mayonnaise sandwiches.

On May 28, 1987, the Pittsfield District Court conducted a preliminary hearing and ordered that the child, then eight years of age, be referred to Concord Psychological Associates for counseling. See N.H.Rev. Stat.Ann. §§ 169-C:15, 16. The court also granted legal supervision of the child to DCYS, left placement of the child with Valerie Watterson, and ordered DCYS to facilitate the counseling sessions and "to conduct an appropriate investigation, including, but not limited to home environment study." Beginning June 11, 1987, the child attended weekly counseling sessions at Concord Psychological Associates with defendant-appellee Janet Seymour, a psychologist who was not yet certified. Seymour was supervised by defendant-appellee Roland Smith, a board-certified psychologist and director of Concord Psychological Associates.

On June 22, in lieu of a scheduled adjudicatory hearing and without a finding of neglect, DCYS and appellant Valerie Watterson entered an agreement for issuance of a consent order. See N.H.Rev.Stat.Ann. § 169-C:17. The consent order mandated that, "[The child] shall continue counselling at Concord Psychological Associates, with a report from Concord Psychological Associates filed with this court not later than forty-five days from the date of this agreement." The order also stated that DCYS would assist Valerie in transporting the child to the counseling sessions, that Valerie would submit to psychological evaluation, that DCYS would complete a home study with Valerie's cooperation, and that the court retained jurisdiction over the case.

Seymour with the aid of a sign-language interpreter conducted a total of seven psychotherapy sessions with the child from June 11 to July 22, 1987. On Seymour's initiative, the younger child, then three years old, also attended one of the sessions. On July 24, 1987, Seymour reported her findings in writing to social worker Page, stating that the older child revealed during therapy that her grandmother and mother (appellants Violet Bruillard and Valerie Watterson) repeatedly took the girls against their will to a house where the older child was required to sleep in close proximity with boys and a grown man. On one occasion, one male allegedly fondled the older child. The younger child was allegedly threatened with a large knife and subjected to fondling by a young boy while Valerie and the older child watched. The older child also reported being paid for visiting the house, being told not to reveal the visits to anyone, and eventually being informed by her mother in July 1987 (during the period of the counseling sessions) that she would no longer take the girls to the house.

On the basis of these findings, Seymour concluded that the girls' grandmother, Violet, may have been "prostituting [the older child] and probably [the young child] to a group of people, likely a sex ring." Seymour stated that Valerie, the mother, was only partially aware of the events at the house but failed to protect the children from the abuse. Seymour concluded her report by recommending that DCYS initially confront Valerie Watterson with the accusations and then, if necessary, remove the girls from appellants' home.

The same day Seymour issued her report, Page sought and obtained an ex parte order from the Pittsfield District Court for the immediate removal of both children from appellants' home, citing the information gathered by Seymour. See N.H.Rev. Stat.Ann. § 169-C:6. That evening law enforcement officials took the two girls from appellants' home and placed them in separate foster homes. On July 27, 1987, Page filed new Abuse and Neglect Petitions with regard to the two children, alleging that they were subject to sexual abuse by Valerie Watterson and Violet Bruillard. See N.H.Rev.Stat.Ann. § 169-C:7.

On September 24, 1987, in connection with the proceedings, Seymour swore out an affidavit detailing her findings regarding the two children. In her affidavit, Seymour attested that she believed, based on her weekly psychotherapy sessions with the older child and the single session with the young child, that the children were subjected to some sort of child prostitution/satanic worship activity (involving "the killing of animals and children," "ugly hats (perhaps headdresses) with horns," and "men in robes"), at a location identified by the girls as "Mike Chickering's house." Seymour's affidavit was apparently used by the Merrimack County Sheriff's office to obtain a search warrant for the Chickering house, where the only evidence of child prostitution and satanic worship found by police was a catalog for pornographic films and an ordinary letter opener.

On May 25, 1988, after eight days of testimony, the Pittsfield District Court ruled that no evidence supported the allegations of ritual sexual abuse occurring at the Chickering residence and so dismissed those particular charges. See N.H.Rev. Stat.Ann. §§ 169-C:18, 19. However, the court stated that it was "obvious" that the older child had been sexually abused and that the young child suffered some traumatic incident that could be classified as abuse. Valerie Watterson and Violet Bruillard appealed the latter findings to the superior court, see N.H.Rev.Stat.Ann. § 169-C:28, but DCYS voluntarily withdrew the Abuse and Neglect Petitions before further proceedings were conducted.

Appellants brought this civil action on July 12, 1990, in the United States District Court for the District of New Hampshire against DCYS social worker Page and appellees Seymour and Smith of Concord Psychological Associates. Appellants alleged in their complaint, as amended, that all three defendants were liable pursuant to 42 U.S.C. § 1983 for depriving appellants of their liberty and property without due process of law. The complaint contained pendent state law claims against Seymour and Smith for failing to act with due care with regard to professional standards. The amended complaint also brought state law claims of malicious prosecution and abuse of process against defendant Page, who is not a party to this appeal.

Seymour and Smith moved to dismiss all claims against them under Fed.R.Civ.P. 12(b)(6) on grounds that they are immune from civil liability. The district court granted these motions on August 12, 1991, holding that the two psychologists had absolute quasi-judicial immunity from the § 1983 claims as court-appointed psychologists, and had state statutory immunity from liability under the state law claims pursuant to the New Hampshire Child Protection Act. See N.H.Rev.Stat.Ann. § 169-C:31. Appellants appeal from the final judgment dismissing the complaint against Seymour and Smith issued pursuant to Fed.R.Civ.P. 54(b) on February 7, 1992.

II.

A. Section 1983 Claims

We need not decide whether the district court correctly held that a court-appointed psychologist is entitled to absolute immunity from claims in connection with her duties as a quasi-judicial officer. Compare Myers v. Morris, 810 F.2d 1437, 1466-67 (8th Cir.) (holding that court-appointed psychologists have absolute immunity), cert. denied, 484 U.S. 828, 108 S.Ct. 97, 98 L.Ed.2d 58 (1987) with Hodorowski v. Ray, 844 F.2d 1210, 1215-16 (5th Cir. 1988) (refusing to extend absolute immunity to child protective service workers). This is a difficult and, in this circuit, novel question, on which there is no conclusive authority. See Frazier v. Bailey, 957 F.2d 920, 931 n. 12 (1st Cir. 1992); see also Snell v. Tunnell, 920 F.2d 673, 686-89 (10th Cir. 1990) (reviewing various court positions on absolute immunity for child abuse investigation participants), cert. denied, ___ U.S. ___, 111 S.Ct. 1622, 113 L.Ed.2d 719 (1991). In Burns v. Reed, ___ U.S. ___, 111 S.Ct. 1934, 114 L.Ed.2d 547 (1991), the Supreme Court cautioned that the "presumption is that qualified rather than absolute immunity is sufficient to protect government officials in the exercise of their duties." Id. ___ U.S. at ___, 111 S.Ct. at 1939. The Court went on to say that it had been "'quite sparing' in [its] recognition of absolute immunity, and [had] refused to extend it any 'further than its justification would warrant.'" Id. (citations omitted). We do not suggest that absolute immunity could not exist for these psychologists in the present circumstances. But since for more conventional reasons appellees are clearly entitled to prevail, we rest our decision exclusively on those reasons.

Except perhaps for the allegation that Seymour gave false testimony in court, appellants have alluded to no facts that seem even remotely sufficient to show a violation of the federal constitution by the two psychologists. And even assuming Seymour testified falsely, and even assuming her false testimony might otherwise give rise to a claim of constitutional dimensions, she would still be immune from suit under § 1983 because of the absolute immunity afforded to witnesses for their testimony in the course of judicial proceedings. Infra. We, therefore, sustain the dismissal of the § 1983 claims.

To bring an action under § 1983, a plaintiff must show both the existence of a federal constitutional or statutory right, and some deprivation of that right as a result of defendants' actions under color of state law. Willhauck v. Halpin, 953 F.2d 689, 703 (1st Cir. 1991). Appellants claim that Seymour and Smith acted under color of state law to deprive them of their right to due process of law in violation of the Fifth and Fourteenth Amendments. We shall assume that the Pittsfield District Court order for counseling and reporting by Concord Psychological Associates provided a sufficient basis for these private defendants to be acting under color of state law. See Frazier, 957 F.2d at 928; Rodriques v. Furtado, 950 F.2d 805, 813-14 (1st Cir. 1991). A likely alternative ground for affirming the district court is qualified immunity. However, before even reaching qualified immunity, a court of appeals must ascertain whether the appellants have asserted a violation of a constitutional right at all. Siegert v. Gilley, ___ U.S. ___, ___, 111 S.Ct. 1789, 1793, 114 L.Ed.2d 277 (1991).

Appellants do not allege that the procedures provided under New Hampshire law for child neglect and abuse petitions, concededly followed in this case, are constitutionally inadequate. See N.H.Rev.Stat. Ann. § 169-C:1 et seq. Instead, they make a substantive due process claim, viz., that by means of Seymour's report, appellees deprived them of a constitutionally protected liberty interest in family integrity, including the care, custody and supervision of the children. Seymour is said to have conspired with Page to conduct an unauthorized investigation of the family's affairs while also counseling the older child. Seymour was allegedly negligent in her counseling, and this negligent counseling and investigating supposedly led to incorrect conclusions about the involvement of Valerie and Violet in the sexual abuse of the girls. These incorrect conclusions, contained in Seymour's report, enabled DCYS to obtain court approval for the removal of the children from appellants' home, thereby depriving appellants of their constitutionally protected liberty interest in family integrity. Appellee Smith's purported liability stems solely from his allegedly-inadequate supervision of Seymour at Concord Psychological Associates.

Taking all of plaintiffs' allegations as true, we see only three possible bases for the § 1983 claim against Seymour: first, she "conspired" with Page to investigate appellants' family without express court authority and direction to do so; second, she negligently counseled and interviewed the children; and third, she presented false testimony and withheld information from the court. The first two theories fall short, however, of stating any federal constitutional claim. While the Supreme Court has recognized an abstract fundamental liberty interest in "family integrity," the Court has never found that interest to be absolute or unqualified. Frazier, 957 F.2d at 929-30. The government has a compelling interest in the welfare of children, and the relationship between parent and child may be investigated and terminated by the state provided constitutionally adequate procedures are followed. Santosky v. Kramer, 455 U.S. 745, 766, 769, 102 S.Ct. 1388, 1401, 1403, 71 L.Ed.2d 599 (1982). The right to family integrity clearly does not include a constitutional right to be free from child abuse investigations. See Stanley v. Illinois, 405 U.S. 645, 649, 92 S.Ct. 1208, 1211-12, 31 L.Ed.2d 551 (1972) (stating that the State has a "right — indeed, duty — to protect minor children through a judicial determination of their interests in a neglect proceeding"); Weller v. Department of Social Servs., 901 F.2d 387, 391 (4th Cir. 1990); Myers, 810 F.2d at 1462. If while engaged in treating the children under court direction, Seymour, in conjunction with Page, looked into whether the children had been abused by appellants, such a joint undertaking would not, without more, violate any constitutional right of appellants. The second factual basis, that Seymour performed the therapy sessions and reported her findings with a lack of due care, at most states a claim of negligence, which is insufficient to constitute a deprivation of due process of law. Daniels v. Williams, 474 U.S. 327, 332-34, 106 S.Ct. 662, 665-66, 88 L.Ed.2d 662 (1986).

Appellants' third allegation, that Seymour conspired with Page to present false testimony to and withhold material evidence from the court hearing the abuse charges, fails for a different reason: all witnesses at judicial proceedings have an absolute immunity from damages liability based on their testimony. Briscoe v. LaHue, 460 U.S. 325, 326, 103 S.Ct. 1108, 1110-11, 75 L.Ed.2d 96 (1983). This immunity applies even to public officials who knowingly give false testimony. Id. at 345, 103 S.Ct. at 1120-21. Seymour thus had absolute immunity for her testimony, even assuming it was either false or incomplete.

The § 1983 claim against Smith is based solely on his actions as the supervisor of Seymour's counseling and investigation. Because Seymour violated no constitutional rights of appellants in her counseling and investigation, we find even less basis for recovery against Smith for supervising her. See Frazier, 957 F.2d at 931-32.

For these reasons, the § 1983 claims against Seymour and Smith were properly dismissed.

B. State Law Claims

The district court held that the two psychologists, Seymour and Smith, had immunity from the state law claims pursuant to a state statute, N.H.Rev.Stat.Ann. § 169-C:31, which immunizes persons who report suspicions of child abuse to the proper state authorities in good faith. Appellants argue that the district court misapplied the immunity statute because their state law claims against appellees stem from the lack of due care in performance of the counseling services, not from Seymour's subsequent report of suspected child abuse (which, appellants concede, is protected by the immunity statute).

We reject appellants' argument. The injuries alleged in their complaint are separation from the children, damage to their reputations, and various forms of emotional distress. No harm to the children as the result of their being negligently counseled is alleged, nor was suit brought on the children's behalf to complain of the alleged malpractice. All the asserted harms resulted from the state's removal of the children. Seymour's and Smith's sole connection to that separation was Seymour's report to DCYS of her suspicions that the girls were being sexually abused. Clearly, Seymour's report of suspected abuse falls squarely within the meaning of "a report pursuant to this chapter" as defined by N.H.Rev.Stat.Ann. § 169-C:31. See Petition of Bagley, 128 N.H. 275, 280, 513 A.2d 331 (1986) (interpreting provisions of the N.H. Child Protection Act). While appellants contend that the Abuse and Neglect Petition would not have been filed but for the allegedly negligent manner in which Seymour conducted the counseling sessions, we find no support in New Hampshire law, nor was any cited, for removing the immunity protection of N.H.Rev.Stat.Ann. § 169-C:31 if the report is the product of negligently administered psychotherapy. See State v. Howland, 125 N.H. 497, 500-02, 484 A.2d 1076, 1077-78 (1984) (discussing the scope of statutory immunity under N.H.Rev.Stat.Ann. § 169-C:31).

III.

For the reasons stated above, we affirm the district court's dismissal of appellants' complaint against appellees Seymour and Smith.
