Post-Craniotomy Recovery Experience Scale (PCRES)
A 35-item patient-reported outcome measure that assesses identity disruption, real-world cognition, emotional regulation, grief, neurofatigue, social connection, the medical-experience gap, and hope after brain surgery — the subjective recovery experience that standard instruments don't measure.
Why This Instrument Exists
Standard screening instruments were designed for other populations. The PHQ-9 screens for depression. The GAD-7 screens for anxiety. The MoCA tests clinic cognition. None of them ask whether the patient still feels like themselves, whether their fatigue is proportional to activity, whether they grieve for abilities they lost, or whether their medical team understands what daily life is actually like.
The PCRES asks all of these things. It takes 5-8 minutes. It fits on two sheets of paper. It gives the clinician information that cannot be obtained any other way.
Key facts: 35 scaled items across 8 domains, 2 unscored open-ended questions, 1 global quality-of-life rating (0-10). 5-point Likert scale (0-4). Higher scores = better across all domains after reverse scoring. Total score range: 0-140. Recall period: past 2 weeks. Completion time: 5-8 minutes. Free, open, no license fees.
What It Measures
Eight domains capturing the full recovery experience:
Does the patient still feel like themselves?
4 itemsDinner-table cognition, not clinic cognition
5 itemsNeurobiological dysregulation presenting as personality change
4 itemsRational grief, not pathological depression
4 itemsQualitatively different from normal or depression fatigue
5 itemsIsolation driven by deficits, fatigue, and "you look great"
4 itemsThe gap between clean imaging and daily suffering
4 itemsLow scores may warrant prompt follow-up and broader mood assessment
5 itemsWhat Makes This Different
| Standard Tool | What It Asks | What It Misses |
|---|---|---|
| PHQ-9 | “Little interest or pleasure in doing things” | “I don't feel like myself anymore” |
| GAD-7 | “Feeling nervous, anxious, or on edge” | “I'm afraid the person I was isn't coming back” |
| MoCA | Serial 7s, clock drawing, word recall | “I can't follow a dinner conversation anymore” |
| MDASI-BT | “Difficulty remembering things” | “My doctor says I'm doing great but I feel terrible” |
| None | — | “What is the hardest part nobody warned you about?” |
How to Use It
Who completes it: The patient, either on paper in the waiting room or on their phone via the online assessment. Caregivers may assist but the patient should answer.
Administration schedule: 2 weeks, 6 weeks, 3 months, 6 months, and 12 months post-surgery. The value compounds with serial measurement — trajectory matters more than any single score.
Completion time: 5-8 minutes. Patients report that the open-ended questions (36 and 37) are often the most meaningful part of the assessment.
Recall period: Past 2 weeks, matching the PHQ-9 and GAD-7 to facilitate concurrent administration.
Scoring: 5-point Likert scale (0-4). Thirteen items are reverse-scored. After reverse scoring, higher = better across all domains. Total score range: 0-140. Domain percentages and clinical flags are calculated automatically in the online version.
Clinical Flags
The thresholds below are proposed interpretation aids for research use and clinical exploration. They are suggestive, not diagnostic, and have not yet been psychometrically validated.
| Domain | Threshold | Flag | Recommended Action |
|---|---|---|---|
| A. Identity | ≤50% (proposed) | Warning | Consider neuropsychology referral; explore identity narrative |
| B. Cognition | ≤50% (proposed) | Warning | Formal neuropsych testing; screen for treatable causes |
| C. Emotional Reg. | ≤50% (proposed) | Warning | Screen for PTSD/adjustment disorder; assess medication-emotion interactions |
| D. Grief & Loss | ≤50% (proposed) | Monitor | Normalize grief; explore with patient; consider support group |
| E. Neurofatigue | ≤50% (proposed) | Warning | Rule out medical causes; differentiate neurofatigue from depression |
| F. Social | ≤50% (proposed) | Warning | Assess caregiver burden; consider support group; explore barriers |
| G. Medical Gap | ≤50% (proposed) | Alert | Explore whether the patient feels misunderstood or under-supported |
| H. Hope & Agency | ≤35% (proposed) | Priority | Consider same-day mood and suicide risk screening if clinically indicated |
Serial tracking: A subscale that worsens by 4+ points between visits is a proposed review threshold pending formal reliability testing. Hope & Agency (H) has a lower exploratory threshold (≤35% vs ≤50%) because this domain overlaps with hopelessness and depression measures. It should be used as a prompt for additional assessment, not as a stand-alone suicide screen.
Implementation in Your Practice
Waiting room workflow: Print the QR code card (available through Provider Setup) and post it in your waiting area. Patients scan with their phone and complete the assessment before their visit. Results arrive in your inbox.
EMR documentation: The PCRES is designed to complement, not replace, PHQ-9/GAD-7 screening. Document the total score, any flagged domains, and the patient's open-ended responses. The open-ended responses often contain the most clinically actionable information.
Who administers: The patient self-administers. A nurse or MA can assist with distribution and collection. Scoring is automatic in the online version.
Reverse-Scored Items
Thirteen items are phrased so that higher raw scores indicate worse outcomes. These items must be reverse-scored before calculating domain and total scores.
Reverse-scored items: 2, 3, 10, 11, 12, 13, 14, 15, 16, 20, 21, 25, 26
Formula: 0→4, 1→3, 2→2, 3→1, 4→0 (scored_value = 4 - raw_value)
After reverse scoring, higher = better across ALL domains and total score. The online assessment handles this automatically.
Validation Status
The PCRES is currently in Phase 3 (content validity) of a multi-phase psychometric validation pathway consistent with COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) and FDA Patient-Reported Outcome guidance.
Planned Psychometric Targets
Cronbach's alpha ≥ 0.70 per subscale
ICC ≥ 0.70 (test-retest, 2-week interval)
CFA: RMSEA < 0.08, CFI > 0.90, loadings ≥ 0.40
Item-total correlations ≥ 0.30
Convergent/discriminant validity against PHQ-9, GAD-7, FACT-Br
Construct Rationale: PCRES vs. Depression
This section answers the reasonable question: “How is this intended to differ from depression measures?” These are conceptual hypotheses to be tested during formal validation.
Domains with Minimal Conceptual Overlap (6 of 8)
Identity disruption and depression can coexist, but they are not the same construct. A patient may report not feeling like themselves even without meeting criteria for major depression.
Depression can produce diffuse cognitive complaints. The PCRES is intended to measure context-specific, lived cognitive strain such as following conversation, multitasking, and reading retention.
Grief after brain surgery may overlap with depressive symptoms, but direct assessment helps distinguish grief for lost function from a primary mood disorder.
Post-neurosurgical fatigue may be disproportionate to activity and exacerbated by cognitive demand. The PHQ-9 was not designed to separate neurofatigue from depression-related fatigue.
Post-craniotomy social isolation may be driven by embarrassment about deficits, reduced cognitive capacity for social interaction, neurofatigue, or feeling misunderstood by others.
This construct has no direct analog in standard depression instruments. It is intended to assess the gap between objective medical progress and subjective patient experience.
Domains with More Conceptual Overlap (2 of 8)
Crying more easily, mood swings, emotional numbness, and irritability overlap with PHQ-9 Items 1, 6, 9 and GAD-7 irritability items. However, the PCRES targets neurobiologically-mediated dysregulation after neurosurgery rather than mood disorder per se.
This domain overlaps with hopelessness and anhedonia measures. Low scores should prompt broader clinical assessment rather than stand-alone conclusions.
The Clinical Argument
The strongest argument for the PCRES is the patient who scores below threshold on the PHQ-9, below threshold on the GAD-7, performs normally on the MoCA — and is suffering. This patient exists in nearly every neurosurgical practice. When a patient scores 4/16 on Identity, 8/20 on Real-World Cognition, and 4/16 on Medical-Experience Gap while scoring 0 on the PHQ-9, the instrument is doing exactly what it was designed to do.
Validation Hypotheses to Be Tested
| Comparison | Hypothesized r | Rationale |
|---|---|---|
| Total PCRES vs PHQ-9 | 0.30–0.50 | Shared variance on C, H only |
| Domains C, H vs PHQ-9 | 0.40–0.60 | Moderate overlap |
| Domains A, B, D, E, F, G vs PHQ-9 | < 0.20 | Lower expected overlap |
| Total PCRES vs GAD-7 | < 0.30 | Weak; some C-domain irritability |
| Total PCRES vs FACT-Br | 0.40–0.60 | Related quality-of-life construct |

The Argument for This Instrument
Brain tumor and meningioma literature consistently describe meaningful psychosocial burden after surgery, while standard follow-up often focuses more on structural recovery than on subjective recovery experience.
Zamanipoor Najafabadi et al. documented psychosocial deficits persisting up to 9 years after meningioma surgery. Existing validated tools such as the PHQ-9, GAD-7, FACT-Br, and symptom inventories were not designed specifically for the subjective post-craniotomy emotional recovery experience.
The PCRES was developed as a proposed instrument for this population and construct and is currently undergoing formal psychometric validation.
