The PCL-R (Hare Psychopathy Checklist-Revised, Second Edition, 2003) is a 20-item clinician rating of psychopathic traits scored from a semi-structured interview plus collateral records. Forensic psychologists and psychiatrists use it in sentencing, civil commitment, parole, and dangerous-offender evaluations. A defensible write-up reports the total as a measurement band against a named comparison group and never as a diagnosis. This page covers how to document PCL-R results, with a fictional sample.

The PCL-R (Hare Psychopathy Checklist-Revised, 2nd Edition; Robert D. Hare; Multi-Health Systems, 2003, following the 1991 first edition) is a 20-item clinician rating scale for psychopathic traits in adults aged 18 and older. Each item is rated 0, 1, or 2 against lifetime functioning from a semi-structured interview combined with review of collateral records, for a total of 0 to 40; the publisher's stated timing is 90 to 120 minutes of interview, about 60 minutes of collateral review, and 15 to 20 minutes of rating, and the product is sold at qualification level C in handscored and software formats. The items group into two factors, an interpersonal and affective Factor 1 and a lifestyle and antisocial Factor 2, and four published facets (Interpersonal, Affective, Lifestyle, Antisocial). Its siblings are separate instruments with their own manuals and comparison samples: the PCL:SV (Screening Version; Hart, Cox, and Hare, 1995), an adult screen with a shorter interview, and the PCL:YV (Youth Version; Forth, Kosson, and Hare, 2003) for ages 12 to 18. As of September 2026 the second edition remains the current product on the publisher's United States and Canadian storefronts, with no third edition or norm update announced; MHS holds the copyright for the PCL-R family after acquiring Darkstone Research Group's assets in November 2019 and styles the mark Hare PCL-R with a trademark symbol.
The load-bearing fact for the write-up is what the number is not. A PCL-R total expresses degree of correspondence with the construct the instrument measures; it is not a DSM-5-TR diagnosis (psychopathy is not one), not a probability of future violence, and not a legal finding. The 30-point threshold familiar from North American research is a classification convention for a dimensional construct, and a 2017 item-response analysis counted more than 8.5 million different rating combinations that sum to exactly 30. A second fact governs the courtroom: single-rater agreement in the manual's research samples is high, but opposing evaluators in real cases have agreed at intraclass correlations of .39 to .59, with differences usually favoring the retaining side, so the manual's standard error of measurement understates the uncertainty of scores offered in litigation. A defensible section therefore documents the frame before the number: the question and the role, the interview and collateral sources, the rater's qualification and any second rating, the total as a band against a named comparison group, the pattern at the level of the published labels, and the limits. The forensic evaluation report page covers the whole-report architecture this section sits inside, and the violence risk assessment page covers the instruments that carry the risk opinion.
Forensic psychologists and psychiatrists are the users, and the settings are the highest-stakes ones in behavioral health: sexually violent predator and civil commitment evaluations (Texas's statute requires testing for psychopathy without naming an instrument), capital sentencing in the states that ask about future dangerousness, where a 2020 statement of concerned experts and a published rebuttal disagree about whether the PCL-R belongs there at all, parole and release reviews, pre-sentencing evaluations, Canadian dangerous-offender and long-term-offender assessments under Part XXIV of the Criminal Code and Correctional Service Canada psychological risk assessments, Australian high-risk offender proceedings in Queensland, New South Wales, Victoria, and Western Australia, and correctional treatment planning. Adolescents are assessed with the PCL:YV, with the field's own caution that psychopathy measures should not drive long-term placement or transfer decisions. The readers are judges and juries, prosecutors and defense counsel, parole boards, opposing experts who will rescore the same file, and the evaluee, whose liberty the label can affect. The section usually sits inside a forensic evaluation report or a court report beside personality inventories such as the MMPI-3, PAI, or MCMI-IV, which answer different questions; it has no place in a capacity evaluation or a clinical psychological evaluation report unless the referral question genuinely turns on psychopathic traits.
No statute, court rule, or publisher document prescribes a PCL-R report format. What the professional guidelines, the case law, and the instrument's own method dictate is the content: the question and the role, the two-part procedure with its sources, the rater's qualification, the total as a band against a named group, the pattern at the level of the published labels, the limits, and the hand-off to the risk instrument. Each section below carries the pitfall that most often undermines it in cross-examination.
Referral question, legal standard, and role. Open with who ordered or retained the evaluation and on what date, the psycholegal question the PCL-R is offered to inform (treatment amenability, a statutory risk element, release planning), your role, and the notice the evaluee received about purpose, limits of confidentiality, and recipients. State what the section will and will not answer: a PCL-R total describes a trait pattern; it does not decide a statutory element or a sentence. Pitfall: A PCL-R section that opens with the score. Without the question and the role, the reader cannot tell what the number is for, and the label starts doing the legal work before the evidence is on the page.
Instrument, procedure, and sources. Name the instrument in full with edition and publisher (Hare Psychopathy Checklist-Revised, 2nd Edition; Multi-Health Systems, 2003). Then document the two-part method: interview dates, durations, setting, and whether the evaluee participated fully, partially, or declined; every category of record reviewed with date ranges; collateral interviews; and records requested but not received. If no interview was possible, say that a file-only procedure was used and that the manual's file-review comparison samples apply; if any item could not be rated, say that the total was prorated per the manual, without reproducing the procedure. Pitfall: "PCL-R interview conducted" when the ratings rested on records, or a prorated total presented as if all 20 ratings were made. Both are impeachable on the first question about method.
Rater qualification and second-rater procedure. State your licensure, PCL-R-specific training (the publisher's authorized program or documented equivalent), forensic experience, and how often you use the instrument. If a second trained rater scored the case, say whether the rating was independent and blind, what materials the second rater used, both totals, and whether the averaged score or a consensus is being reported. The author recommends averaging two independent ratings where feasible; report the disagreement rather than choosing the more convenient number. Pitfall: "Scored by a qualified examiner" with no training or second rating on the record. Publisher qualification level C is a purchasing standard, not evidence of competence with this instrument.
Total score as a band with the named comparison group. Report the total with the manual's standard error of measurement as a band (about 3 points either side for a 68 percent band and roughly 6 for a 95 percent band, for a single rating in the manual's male offender sample as reported in the literature), name the comparison group and procedure that any percentile rests on (male justice-involved, male forensic psychiatric, or female justice-involved; standard or file-review sample), and give the percentile as a band in prose. If a research-convention threshold is mentioned, attribute it as a convention and say whether the band crosses it. Pitfall: A bare integer, or a percentile with no comparison group. The 2015 Canadian case-law review found single-rater agreement of .59 in court, so the manual's 2.90 understates the uncertainty of any score offered in litigation.
Factor and facet pattern in prose. Describe the relative elevation across the published labels only (Factor 1, interpersonal and affective; Factor 2, lifestyle and antisocial; the four facets Interpersonal, Affective, Lifestyle, and Antisocial) and whether both raters saw the same shape. Pattern language tells the court something psychometrically real; item narrative reproduces protected content and reads as coaching. Pitfall: An item-by-item walk through the rating booklet, or the facet pattern rendered as a list of adjectives about the person. The same total can arise from millions of rating combinations, which is why the shape matters and the epithet does not.
Limits and inferential boundaries. State that the result is not a diagnosis (psychopathy is not a DSM-5-TR category), not an individualized prediction of violence or recidivism, and not a legal finding; that thresholds are conventions that differ by research tradition; and that the field-reliability and adversarial-allegiance literature exists, with the safeguards you used named. Note any gap in the record base and its direction of effect on confidence. Pitfall: Limits omitted, or limits so total that they undercut the section. State what the score does support first (a structured description of documented traits), then what it does not.
Integration with structured risk assessment and the formulation. Cross-reference the structured risk instrument that carries the risk opinion (HCR-20 Version 3, Static-99R, or another purpose-built tool, each in its own section under its own manual), the dynamic and protective factors, and the treatment and supervision conditions. Keep the PCL-R as one contributor to the formulation, and keep ultimate-issue language where your jurisdiction and role put it. Pitfall: "High psychopathy, therefore high risk." Comparative meta-analysis finds the PCL-R and eight other tools predict violence at similar moderate levels, with Factor 1 at chance among men; the score is a trait description, not the risk estimate.

Scenario: a court-ordered pre-sentencing evaluation of a 34-year-old man in which the court asked about psychopathic traits as they bear on treatment planning and supervision, written by a court-appointed psychologist with an independent second rater, a fictional mid-range total reported as a band, and the risk opinion kept in its own section. All details are fictional.
Patient: D.K., 34 · Setting: Court-ordered pre-sentencing psychological evaluation, state superior court · Clinician: M. Hartley, PhD, licensed psychologist · Note date: 09/17/2026
Referral and legal question: By order dated 08/24/2026, the court appointed this examiner to conduct a pre-sentencing psychological evaluation and asked, among other questions, whether D.K. shows psychopathic traits relevant to treatment amenability and supervision planning. This section reports the Hare Psychopathy Checklist-Revised, 2nd Edition (PCL-R; Hare, 2003; Multi-Health Systems). It answers the descriptive question the court asked; it does not by itself answer any sentencing question, and the risk opinion appears in the violence risk section of this report. D.K. was informed of the purpose of the evaluation, the absence of confidentiality, and who would receive the report, and he agreed to proceed.
Sources and administration conditions: The PCL-R was completed by the standard procedure: a semi-structured interview plus review of collateral records. The interview took place in two sessions at the county detention center on 09/09/2026 (2 hours) and 09/10/2026 (1 hour 30 minutes); D.K. participated fully in both. Records reviewed: the charging documents and the presentence investigation report (received 09/01/2026); jail classification and conduct records from the current detention (received 09/03/2026); probation records from 2019 to 2023; outpatient mental health and substance use treatment records from two agencies covering 2017 to 2024; school records through the tenth grade; and employment verification for three employers. A collateral telephone interview with D.K.'s older sister took place on 09/11/2026. Juvenile court records were requested on 09/02/2026 and had not been received by the date of this report; their absence is noted in the limits below. The index offense is described in the offense history section of this report and is not repeated here. All 20 items could be rated; no item was omitted and no prorating was needed.
Rater qualification and second rating: This examiner is a licensed psychologist in forensic practice since 2015, completed the publisher-authorized PCL-R training program in 2021, and uses the instrument regularly in court-ordered evaluations. A second licensed psychologist trained in the instrument rated the case independently on 09/12/2026 from the recorded interview and the same record set, without seeing my ratings; no consensus meeting was held. Following the author's recommendation that two independent ratings be averaged where possible, both totals are reported below and the average is used.
Total score with measurement error: My total was 23; the second rater's total was 21; the averaged total is 22. The two ratings differ by less than the standard error of measurement the manual reports for a single rating (about 3 points), which is the level of agreement expected under research conditions. Interpreted against the manual's standard-procedure comparison group of adult male justice-involved persons, an averaged total of 22 falls in the middle range of that group, in a percentile band around the median rather than in its upper range. Allowing roughly two standard errors either side, the 95 percent band spans approximately 16 to 28. That band does not reach the 30-point threshold used as a research convention in North American studies, and the band is the result: the single integer should not be read as an exact quantity.
Factor and facet pattern: Described at the level of the published labels only: the profile was relatively more pronounced on the Lifestyle and Antisocial facets (Factor 2) than on the Interpersonal and Affective facets (Factor 1), which were comparatively modest. Both raters saw the same shape. In plain terms, the documented history weighs more heavily on the behavioral and lifestyle side of the construct than on the interpersonal and affective side. No item-level ratings are reproduced here; the rating booklet, item descriptions, and scoring criteria are the publisher's protected materials.
Limits: This result is not a diagnosis: psychopathy is not a DSM-5-TR diagnostic category, and the PCL-R describes degree of correspondence with the construct the instrument measures. It is not a prediction of future behavior: comparative meta-analysis finds the PCL-R and other risk tools predict violence at similar moderate levels, with the interpersonal and affective factor adding little, so no individual likelihood is derived from this score. Thresholds such as 30 are classification conventions from research, not diagnostic or legal criteria, and this evaluation offers none as such. The published field-reliability literature, in which opposing evaluators have shown agreement well below research values, is acknowledged; the safeguards here were a court appointment rather than party retention, a predetermined record base, a recorded interview, and an independent second rating with both totals disclosed. The missing juvenile records could bear on the lifetime history the instrument rates, and the total is reported with that gap stated.
Integration and formulation: The PCL-R contributes one structured description to the formulation. The violence risk section reports the HCR-20 Version 3 separately, including dynamic and protective factors and the supervision conditions under which risk would be manageable, and the treatment section addresses amenability using treatment history and current motivation rather than this score alone. Nothing in this section should be read as an opinion on the sentence; that question belongs to the court.

Generate a note from bulletsUnited States: the write-up sits inside a legal machine, and the parts are citable. No statute names the PCL-R. Sexually violent predator laws require an assessment: Texas Health and Safety Code 841.023 requires a clinical assessment based on testing for psychopathy, a clinical interview, and other appropriate assessments and techniques, which is a requirement to test for the construct, not to use this product (LAW). Admissibility runs through Frye in some states and Daubert in the federal courts and others, is decided purpose by purpose, and in the published case-law reviews by DeMatteo and colleagues has seldom been the subject of a successful challenge; the capital context traces to Barefoot v. Estelle (1983), in which the Supreme Court allowed psychiatric future-dangerousness testimony at sentencing and left its reliability to cross-examination (case law, described here as CONVENTION and practice, not legal advice). The professional framework is the APA Specialty Guidelines for Forensic Psychology (2013) and the AAPL Practice Guideline for the Forensic Assessment (2015): identify the referral question and your role, list every source considered and every source requested but not received, state the limits of your opinions, and keep fee arrangements free of contingency (CONVENTION and ethics, not statute). The use dispute is live: the 2020 Statement of Concerned Experts in Psychology, Public Policy, and Law concluded that the PCL-R should not be used to predict serious institutional violence in capital sentencing, Olver and colleagues published a cautionary note in reply, and DeMatteo and Olver then co-authored a 2021 review of validity, reliability, and admissibility; a report that cites this exchange shows the court it knows the ground. Forensic evaluations are commissioned and paid by the court, a party, or an agency, not billed to health insurance under CPT, and the source of payment changes nothing about method or disclosure (PAYER POLICY).
Canada and Australia require assessments, not this instrument. Criminal Code section 752.1 lets the court remand an offender for up to 60 days for assessment by a designated person before a dangerous-offender or long-term-offender application, with the report filed within 30 days, and section 753 sets the findings the court must make; Correctional Service Canada's Commissioner's Directive 712-1 makes a psychological risk assessment mandatory for conditional-release applications involving persistent or gratuitous violence, sexual offences, detention referrals, and indeterminate or life sentences, and defines it as an integrated evaluation using a variety of scientifically validated methods (LAW and agency POLICY); the PCL-R appears inside these assessments by professional custom (CONVENTION). Queensland's Dangerous Prisoners (Sexual Offenders) Act 2003 provides for examination by two psychiatrists who report independently on the assessed risk and its reasons, requires the report even if the prisoner does not cooperate, and sets an acceptable, cogent evidence standard to a high degree of probability; New South Wales's Crimes (High Risk Offenders) Act 2006, Victoria's Serious Offenders Act 2018 (in force as amended to October 2025), Western Australia's High Risk Serious Offenders Act 2020, and Commonwealth Division 105A run parallel regimes, and none names an instrument (LAW). Edition and norms: the second edition (2003) is current as of September 2026 with no successor announced, so date the edition statement in the report. The publisher's database of 10,896 justice-involved persons and patients is split by group and procedure (5,408 male justice-involved persons, 1,246 male forensic psychiatric patients, and 1,218 female justice-involved persons under the standard procedure; 2,622 male justice-involved persons and 402 male forensic psychiatric patients by file review), which is why a percentile means nothing until the group and procedure are named, and no female file-review or female forensic psychiatric sample is listed. Generalizability is an empirical question: a 21-study meta-analysis of 8,890 people found Black and White participants differing by less than one point on the total, and a 2011 comparison of North American and German file-based ratings found the Antisocial component not invariant across countries, so a report states a caution rather than adjusting a score. Qualification: MHS sells the PCL-R at level C (training or experience with tests plus an advanced degree in an appropriate profession, with state licensure possibly required), Hare's professional-use recommendations add registration with the body that regulates mental health assessment, forensic experience, adequate PCL-R training, use only with populations the instrument is validated for, and averaged independent ratings where possible, and MHS delivers and authorizes PCL-R training (a 16-hour continuing-education program combining an on-demand presentation, live question time with the author, and a two-day live webinar); no fixed number of supervised cases is an MHS rule, so the report states the training you actually have.
This is a sensitive documentation type. The evaluee is usually in custody or facing loss of liberty, the label carries prejudice a court cannot easily set aside, and the report may be read by the evaluee, so write traits and their documented behavioral referents rather than the epithet, and keep the section free of detail that could identify victims or third parties beyond what the record already contains. If you or a client needs immediate support: call or text 988 (US), 9-8-8 (Canada), or Lifeline 13 11 14 (Australia). Before releasing raw scores, the rating booklet, or other test materials in response to a subpoena or a discovery demand, consult your attorney or board; state rules vary, APA Ethics Standards 9.04 and 9.11 distinguish test data from test materials, and the subpoena response page covers the procedure.

The numbers behind these errors are specific. Opposing evaluators in 23 civil-commitment cases agreed on PCL-R totals at an ICC of .39, with differences usually favoring the retaining party; 29 paired scores in US sexually violent predator case law agreed at .58, only 41.4 percent of the differences fell within one standard error of measurement, and prosecution experts reported 30 or above in nearly 50 percent of cases against under 10 percent for defense experts; 102 Canadian criminal cases with two or more scores agreed at .59, a level the authors note implies a real-world standard error far larger than the manual's 2.90; 108 forensic clinicians shifted their scores toward whichever side they believed had retained them; the nine-tool meta-analysis found the PCL-R no better than other instruments at predicting violence and Factor 1 at chance among men; and more than 8.5 million rating combinations sum to exactly 30.

The PCL-R has 20 items, each rated 0, 1, or 2 by a trained clinician from a semi-structured interview plus collateral records, for a total of 0 to 40 that expresses how closely the documented lifetime pattern corresponds to the construct the instrument measures; the publisher describes the total as usable dimensionally or in a categorical framework. The items group into two factors (Factor 1, interpersonal and affective; Factor 2, lifestyle and antisocial) and four published facets (Interpersonal, Affective, Lifestyle, Antisocial). The manual reports percentiles and standardized scores for specific comparison samples, so a percentile only means something when the group and procedure are named. Two properties govern interpretation: the standard error of measurement for a single rating, about 3 points in the manual's male offender sample as reported in the published literature, which turns an integer into a band of roughly plus or minus 6 at 95 percent; and the fact that the same total can arise from millions of rating combinations, which is why the pattern matters more than the number. A total is never a diagnosis and never a prediction by itself.
No. Thirty is the threshold used as a research convention in North American studies, the published literature (including the 2020 Statement of Concerned Experts) treats it as a convention for a dimensional construct rather than a diagnostic boundary, and psychopathy is not a DSM-5-TR diagnosis. Lower thresholds in the mid-20s have been used in UK and European research on the strength of cross-cultural equating work, and later analyses disputed whether a uniform downward adjustment is justified, so the same raw score does not carry the same meaning across settings. A 2017 item-response analysis counted more than 8.5 million rating combinations that sum to exactly 30, each describing a different profile. The write-up therefore never says that 30 equals a psychopath or that Europe uses 25; it reports the band, says which convention is under discussion and why it is relevant, states whether the band crosses it, and separates that statement from any psychiatric diagnosis or legal finding. When categorical language is unavoidable, call it an instrument-based classification convention and attribute it.
Sometimes, and the report must say so prominently. The standard procedure is a semi-structured interview plus collateral review; the publisher maintains separate file-review-only comparison samples, which confirms that a records-only procedure is contemplated when an interview cannot be obtained and the records are extensive and reliable. The instrument cannot be completed from an interview alone, because collateral information is part of the method. Research comparing independent file-based ratings with full assessments cautions that the two are not automatically interchangeable, so the write-up states the date and circumstances of the offered interview, that the evaluee declined or participated partially, that ratings rested on the available records, which important sources were missing, that the file-review comparison sample was used for any percentile, and that confidence is correspondingly reduced. A refusal is an assessment condition to document, never a trait to score. The AAPL forensic assessment guideline asks for exactly this: list the sources considered, note information requested but not received, and state the limits that follow. A usable sentence: because the evaluee declined the interview, the PCL-R was completed from the collateral record where ratings could be supported, and this departure from the standard procedure limits the certainty of the interpretation.
The one that matches the evaluee and the procedure, named in the report. The publisher's second-edition database contains 10,896 justice-involved persons and patients, split into standard-procedure samples of 5,408 male justice-involved persons, 1,246 male forensic psychiatric patients, and 1,218 female justice-involved persons, plus file-review-only samples of 2,622 male justice-involved persons and 402 male forensic psychiatric patients. Percentiles shift with the group, so a phrase like compared with PCL-R norms conceals a consequential choice. Write, for example, that the total was interpreted against the standard-procedure sample of adult male justice-involved persons, or against the file-review sample of male forensic psychiatric patients, and give the percentile as a band in prose rather than as a table. Note the gaps honestly: the product page lists no female file-review or female forensic psychiatric sample, and cross-cultural work has found the Antisocial component less invariant across countries than the other facets, so an evaluee outside the sampled populations gets a stated caution rather than a laundered percentile.
Do not deny the literature; distinguish population-level bias risk from evidence about your rating, then show the safeguards. The numbers are public: opposing evaluators in 23 Texas civil-commitment cases agreed at an ICC of .39, with differences usually favoring the retaining side (Murrie and colleagues, 2008); 29 paired scores in US sexually violent predator case law agreed at .58, with prosecution experts reporting scores of 30 or above in nearly half their cases against under 10 percent for defense experts (DeMatteo and colleagues, 2014); 102 Canadian criminal cases with two or more scores agreed at .59 (Edens and colleagues, 2015); and an experiment that led 108 forensic clinicians to believe one side had retained them shifted their scores in that side's direction (Murrie and colleagues, 2013). Independent raters working from the same files agreed with each other at .95 while agreeing with state and defense experts at .29 and .14, and even independent Swedish evaluation teams reached only .70 on retest. The defensible answer states who retained you, your PCL-R training, the predetermined record base, the recorded interview, the independent second rating with both totals disclosed, the band rather than the integer, and the acknowledgment that this literature exists. Choosing whichever score produces the more dramatic label is the error the literature documents.
No jurisdiction names it. What the law requires is an assessment or a report; the instrument is a professional choice (CONVENTION). Texas Health and Safety Code 841.023 requires a clinical assessment based on testing for psychopathy, a clinical interview, and other appropriate assessments and techniques, and names no instrument (LAW). Canada's Criminal Code section 752.1 lets the court remand an offender for up to 60 days for an assessment by a designated person before a dangerous-offender or long-term-offender application, with a report filed within 30 days, and names no instrument (LAW); Correctional Service Canada's Commissioner's Directive 712-1 makes a psychological risk assessment mandatory for certain conditional-release applications and defines it as an integrated evaluation using a variety of scientifically validated methods, again without naming a tool (agency POLICY). Queensland's Dangerous Prisoners (Sexual Offenders) Act 2003 provides for examination by two psychiatrists who report independently, requires the report even if the prisoner does not cooperate, and sets an acceptable, cogent evidence standard to a high degree of probability; New South Wales, Victoria, Western Australia, and the Commonwealth run parallel high-risk offender regimes, none of which names the PCL-R (LAW). Admissibility in the United States runs through Frye or Daubert according to the jurisdiction, is purpose-specific, and in the published case-law reviews has seldom been successfully challenged, which is a description of practice, not legal advice.
PCL-R scores correlate with violent and criminal outcomes at the group level, and psychopathic traits can be an important risk factor; that is different from an individualized probability. Yang, Wong, and Coid's 2010 meta-analysis compared nine risk instruments within the same studies and found all of them, and their subscales, predicting violence at about the same moderate level, with the exception of PCL-R Factor 1, which predicted violence only at chance level among men; the authors concluded that tools with this level of accuracy should not be used alone for decisions such as preventive detention. The write-up therefore keeps the PCL-R as a structured description of traits and routes the risk opinion to a purpose-built instrument in its own section: the HCR-20 Version 3 for structured professional judgment about violence (its authors recommend but no longer require a formal PCL-R rating for the relevant item), Static-99R and Stable-2007 for sexual recidivism, or another validated tool, each interpreted under its own manual with dynamic and protective factors and management conditions. Personality inventories such as the MMPI-3, PAI, and MCMI-IV answer different questions and substitute for none of these. The violence risk assessment page covers the risk instruments themselves.
No, and the report does not need them. The rating booklet, item descriptions, interview schedule, scoring criteria, and norms are copyrighted materials of Multi-Health Systems, which has held the copyright for the PCL-R family since acquiring Darkstone Research Group's assets in November 2019 and directs reproduction requests to [email protected]; the instrument is sold at qualification level C.

Under APA Ethics Standards 9.04 and 9.11, responses, scores, and interpretation are test data, while the booklet and criteria are test materials that stay out of the report, out of the public court file where the rules allow, and off any public page. An item-by-item narrative also reads as coaching: it tells the next evaluee what a low score looks like. Institutional or digital integration runs through the publisher's licensed platforms (MHS offers GEARS for agencies), a free web version of the checklist has no authorization and is not the instrument, and a subpoena for raw data is handled through counsel, as the subpoena response page describes.
Yes. Give it the facts (the court order or retention and the question, interview dates and participation, records reviewed and records not received, your training and the second rater's procedure, both totals, the comparison group, the facet pattern, the limits you want stated, and the risk instrument used) and it drafts the PCL-R section: sources listed, the total as a band against the named group, the pattern at the level of the published labels, the limits paragraph, and the cross-reference to the risk section, ready for your review. It can also cross-check a finished section for the errors reviewers flag: a bare integer, a percentile with no comparison group, a file-only procedure described as an interview, item-level narrative, a threshold written as a diagnosis, or a score doing the risk opinion's work. BastionGPT is HIPAA-compliant with a signed BAA on every plan, and your data is never used to train models.
