Trauma Screening

Description

This skill helps administer and interpret validated PTSD and trauma screening instruments. The PC-PTSD-5 serves as a brief initial screener, while the PCL-5 provides comprehensive assessment of PTSD symptom severity aligned with DSM-5 criteria.

Clinical Context: These tools help identify probable PTSD, quantify symptom severity, track treatment response, and support clinical decision-making. They are support tools that supplement, not replace, comprehensive trauma-informed clinical evaluation.

⚠️ TRAUMA-INFORMED APPROACH REQUIRED: All trauma screening must follow trauma-informed principles. See references/trauma-informed-approach.md for essential guidance.

Quick Reference: Assessment Selection

Assessment Items Time Purpose Cutoff When to Use
PC-PTSD-5 5 1-2 min Brief screen ≥3 Primary care, triage, initial screening
PCL-5 20 5-10 min Comprehensive assessment ≥33 After positive PC-PTSD-5, treatment monitoring

Decision guide: Start with PC-PTSD-5 for quick screening. If score ≥3, administer full PCL-5. See references/screening-comparison.md for detailed guidance.

Usage

Example requests: "Screen for PTSD", "Administer PCL-5", "Score trauma screening", "Interpret PTSD results"

Quick Reference: Severity Levels

PC-PTSD-5 Interpretation

  • 0-2: Negative screen - PTSD unlikely, routine monitoring
  • ≥3: Positive screen - Administer full PCL-5 for comprehensive assessment

PCL-5 Severity Levels

  • 0-30: Subclinical/mild - Watchful waiting, psychoeducation
  • 31-44: Moderate PTSD - Evidence-based trauma therapy recommended
  • 45-59: Severe PTSD - Active treatment strongly recommended, specialty referral
  • ≥60: Extreme PTSD - Immediate intervention, consider higher level of care

Treatment response: 10-20 point decrease = clinically significant improvement

For detailed severity interpretations and treatment recommendations, see references/severity-levels.md

Interactive Administration (Optional)

Use this mode when the clinician says "start" or "administer" the PC-PTSD-5/PCL-5.

  1. Confirm readiness, use a trauma-informed approach, and remind the patient they can pause or skip questions.
  2. Explain the time frame and response scale for the selected instrument.
  3. Ask one item at a time (verbatim from the asset file) and wait for a response before continuing.
  4. Accept numeric or verbal responses; if unclear or out of range, ask for clarification.
  5. If the patient becomes distressed or safety concerns arise, pause and follow trauma-informed safety guidance before continuing.
  6. After the final item, calculate totals (and cluster scores for PCL-5), interpret severity, and provide next-step guidance.
  7. Offer a brief documentation summary if requested.

Assessment Administration

PC-PTSD-5 (Primary Care PTSD Screen for DSM-5)

Complete assessment details: assets/pc-ptsd-5.md

Quick Facts:

  • 5 binary (Yes/No) questions covering DSM-5 PTSD symptom clusters
  • Score 1 point for each "Yes" response
  • Cutoff ≥3: Optimal balance of sensitivity (93%) and specificity (85%)
  • Positive screen indicates need for full PTSD assessment (PCL-5)
  • Requires trauma exposure; not administered if no trauma history

Items (1 point each for "Yes"):

  1. Nightmares/intrusive thoughts about trauma
  2. Avoidance of trauma reminders
  3. Hypervigilance/easily startled
  4. Detachment/numbing
  5. Guilt/self-blame

Next Steps:

  • Score 0-2: Monitor, reassess if symptoms emerge
  • Score ≥3: Administer full PCL-5 for comprehensive assessment

PCL-5 (PTSD Checklist for DSM-5)

Complete assessment details: assets/pcl-5.md

Quick Facts:

  • 20 items mapping to DSM-5 PTSD criteria (0-4 Likert scale)
  • Total score range: 0-80
  • Cutoff ≥33: Probable PTSD diagnosis (requires clinical interview to confirm)
  • Tracks symptom severity and treatment response
  • Can assess DSM-5 diagnostic criteria via cluster analysis

Symptom Clusters:

  • Cluster B (Items 1-5): Intrusion symptoms (range 0-20)
  • Cluster C (Items 6-7): Avoidance (range 0-8)
  • Cluster D (Items 8-14): Negative cognitions/mood (range 0-28)
  • Cluster E (Items 15-20): Arousal/reactivity (range 0-24)

DSM-5 Provisional Diagnosis Criteria:

  • ≥1 Cluster B item rated ≥2 (Moderately or higher)
  • ≥1 Cluster C item rated ≥2
  • ≥2 Cluster D items rated ≥2
  • ≥2 Cluster E items rated ≥2

Clinical Cutoffs:

  • Total score ≥33: Probable PTSD (clinical interview required for formal diagnosis)
  • 10-20 point change: Clinically significant improvement
  • 5-10 point change: Reliable improvement

For structured clinical decision trees covering screening, treatment selection, safety assessment, and treatment monitoring, see references/clinical-decision-trees.md

⚠️ Safety-First: Assess for suicidal ideation (use suicide-screening), substance use, dissociation. Do NOT begin trauma work if safety concerns present.

Evidence-Based Therapies: PE, CPT, EMDR, TF-CBT

Medications: SSRIs (sertraline, paroxetine, fluoxetine), SNRI (venlafaxine)

Safety Protocols

⚠️ TRAUMA-INFORMED CARE REQUIRED: Follow trauma-informed principles (safety/trust, voluntary participation, patient-controlled pacing, prepare for emotional reactions). See references/trauma-informed-approach.md.

Safety Assessment: Screen for suicidal ideation (use ../../suicide-screening/), assess current safety. Crisis intervention required per ../../docs/references/crisis-protocols.md.

Crisis Resources: 988 Lifeline, Text HOME to 741741, Veterans 988 Press 1, Emergency 911

Escalate when: Active SI, severe impairment, PCL-5 ≥60, psychotic symptoms, severe self-harm

Documentation

PC-PTSD-5 template: assets/pc-ptsd-5.md - Include trauma exposure, item responses, score (0-5), result, next steps.

PCL-5 template: assets/pcl-5.md - Include all 20 items (0-4), cluster subtotals, total score, severity, DSM-5 criteria met, provisional diagnosis, treatment recommendations, safety assessment.

Standards: ../../docs/references/documentation-standards.md

Limitations & Considerations

Support tool, not diagnostic: PCL-5 provides provisional diagnosis; clinical interview required. Scores require interpretation within trauma context. Cultural factors and dissociation affect reporting. Clinical judgment supersedes scores. Use collaborative, trauma-informed approach respecting autonomy and timing. See references/trauma-informed-approach.md.

Special Populations: Military/veterans (combat context), complex trauma (developmental/relational impact), childhood trauma (attachment issues), recent trauma <1 month (acute stress vs PTSD).

Comorbidity: PTSD commonly co-occurs with depression (50%), substance use (30-50%), anxiety. Screen with ../../depression-screening/, ../../substance-screening/, ../../anxiety-screening/. Address in treatment planning.

Workflow Integration
