Psychiatry
Posttraumatic Stress Disorder
Diagnose PTSD with a trauma-informed clinical assessment rather than a self-report score alone, then prioritize manualized trauma-focused psychotherapy. Use symptom measures to track change, assess suicide risk directly, and avoid benzodiazepines because they do not treat core PTSD symptoms and may undermine recovery.
Initial encounter
Triage safety and establish whether PTSD is the treatment target
Separate acute safety needs, probable PTSD, and competing psychiatric syndromes before selecting treatment.
At the first PTSD-focused visit, assess current suicidal ideation, suicidal behavior, intent, planning, access to lethal means, and ability to maintain safety. Use a structured instrument such as the Columbia-Suicide Severity Rating Scale when a reproducible suicide-risk assessment is needed. Escalate to urgent psychiatric or emergency evaluation when imminent self-harm risk cannot be managed in the current setting. ccjmccjmJoint Clinical Practice Guideline on Benzodiazepine Tapering: Considerations When Risks Outweigh Benefits | Journal of General Internal Medicine | Springer Nature Link
Establish trauma exposure before administering symptom screens. The PC-PTSD-5 was designed with a trauma-exposure stem so that patients without reported qualifying exposure do not complete the symptom items; this limits unnecessary screening in the substantial proportion of primary-care patients who are not trauma exposed. PubMedPubMedThe Primary Care PTSD Screen for DSM-5 (PC-PTSD-5): Development and Evaluation Within a Veteran Primary Care Sample - PMC
Do not convert a positive screen into a diagnosis without clinical assessment. PTSD diagnosis requires determining whether symptoms meet the DSM-5 cluster pattern, whether symptoms are clinically significant, and whether another condition better explains the presentation. On CAPS-5, individual symptoms are considered present at a severity rating of 2 or greater, and the diagnostic pattern requires at least 1 intrusion symptom, 1 avoidance symptom, 2 negative cognition/mood symptoms, and 2 arousal/reactivity symptoms.

Prioritize immediate safety planning and level-of-care decisions over routine symptom scoring when the patient reports active suicidal intent or recent suicidal behavior. ccjmccjmJoint Clinical Practice Guideline on Benzodiazepine Tapering: Considerations When Risks Outweigh Benefits | Journal of General Internal Medicine | Springer Nature Link
Ask specifically about alcohol and other substance use, depressive symptoms, anxiety symptoms, mania, and somatic concerns because these constructs may overlap with PTSD presentations and affect treatment sequencing.

Testing
Use screening results to trigger assessment and longitudinal measurement
Choose the shortest validated measure that answers the immediate clinical question.
For opportunistic primary-care screening, PC-PTSD-5 is suited to identifying trauma-exposed patients who need follow-up. Its development study reported excellent diagnostic accuracy, with area under the curve greater than 0.92 for the evaluated screen versions in a veteran primary-care sample. Threshold selection should favor sensitivity when the consequence of a missed case is high and diagnostic follow-up is available; higher thresholds trade sensitivity for fewer positive screens. PubMed+1PubMedThe Primary Care PTSD Screen for DSM-5 (PC-PTSD-5): Development and Evaluation Within a Veteran Primary Care Sample - PMCPubMedEvaluating the Performance of the Primary Care Posttraumatic ...
Use the 20-item PCL-5 when the decision is symptom measurement rather than brief case finding. A systematic review found that recommended probable-PTSD cutoffs varied substantially, from 23 to 49, with 31-33 most frequently identified. Therefore, use a locally validated threshold rather than treating a single universal cutoff as diagnostic across veterans, civilians, primary care, and specialty populations. PubMedPubMedThe Posttraumatic Stress Disorder (PTSD) Checklist for DSM–5 - PMC
For treatment follow-up, repeat the same instrument rather than comparing raw scores across different instruments. In a treatment-seeking military and veteran sample, diagnostic agreement between baseline PCL-5 and CAPS-5 was only moderate-to-weak by kappa despite 84.9% overall consistency, reinforcing that symptom change on PCL-5 and diagnostic remission on CAPS-5 answer related but different questions. PubMedPubMedA comparison of the CAPS-5 and PCL-5 to assess PTSD in military and veteran treatment-seeking samples
Use CAPS-5 when a clinician-administered diagnosis is needed, including when self-report results conflict with the interview, symptom presentation is diagnostically complex, or a formal diagnostic determination will materially change care. PubMedPubMedA comparison of the CAPS-5 and PCL-5 to assess PTSD in military and veteran treatment-seeking samples
Use serial PCL-5 scores to support shared decisions about continuing, adapting, or changing treatment, while reassessing suicidality and functional impairment rather than relying on score change alone.

Avoid using a negative or low self-report result to dismiss trauma-related illness when avoidance, shame, dissociation, literacy, cultural factors, or inconsistent reporting is clinically plausible; proceed with clinician assessment when suspicion remains high.

Definitive treatment
Offer trauma-focused psychotherapy as first-line treatment
Treatment selection should prioritize an evidence-based trauma-focused protocol that the patient can access and engage in.
Offer a manualized trauma-focused psychotherapy to adults with confirmed PTSD unless acute instability prevents outpatient participation. Guideline syntheses consistently identify trauma-focused cognitive behavioral approaches as first-line psychological treatment; named options include cognitive processing therapy (CPT), prolonged exposure (PE), trauma-focused CBT, cognitive therapy, and eye movement desensitization and reprocessing (EMDR). ScienceDirect+1ScienceDirectFocusing on trauma-focused psychotherapy for posttraumatic stress disorder - ScienceDirectPubMedTreatment Guidelines for PTSD: A Systematic Review - PMC
Select CPT when trauma-related beliefs and persistent negative cognitions are prominent treatment targets; select PE when behavioral and cognitive avoidance is central and the patient is willing to engage in systematic exposure-based work. Both CPT and PE target avoidance and isolation and have been associated with reductions in negative cognitions around traumatic memories. JAMA+1JAMAClinical Implications of Trauma-Focused Therapy for VeteransScienceDirectFocusing on trauma-focused psychotherapy for posttraumatic stress disorder - ScienceDirect
Offer EMDR when it is available and acceptable, particularly when patient preference or access favors it over CPT or PE. A systematic overview of meta-analyses found that beneficial effects lasting beyond 1 month after treatment were supported most consistently for trauma-focused CBT interventions and EMDR. ScienceDirectScienceDirectPsychological interventions for adult posttraumatic stress disorder
Do not withhold trauma-focused treatment solely because PTSD is accompanied by common comorbid symptoms. Instead, identify the condition that creates an immediate barrier—such as imminent suicide risk, uncontrolled intoxication, severe mood elevation, or inability to participate safely—and stabilize that barrier while maintaining a plan to initiate PTSD-directed psychotherapy. Concern about comorbidity has contributed to debate about parallel treatment models, particularly for co-occurring substance use disorders. nice org uknice org uk[PDF] PTSD (update) guideline - NICE
Discuss the trauma-processing component explicitly before referral; trauma-focused treatment uses cognitive, emotional, or behavioral techniques in which processing traumatic experience is central to therapy. ScienceDirectScienceDirectFocusing on trauma-focused psychotherapy for posttraumatic stress disorder - ScienceDirect
If the patient declines trauma-focused therapy, revisit preference, practical barriers, and treatment expectations rather than labeling the disorder treatment resistant after one declined referral. Capacity and therapist availability are documented barriers to CPT and PE reach. JAMAJAMAClinical Implications of Trauma-Focused Therapy for Veterans
Use non-trauma-focused psychotherapy only with clarity about the tradeoff: present-centered therapy has been studied, but trauma-focused cognitive behavioral therapies have the broadest empirical support for PTSD and related comorbidities.

Choosing among evidence-based trauma-focused therapies
No source-supported hierarchy establishes that one of CPT, PE, trauma-focused CBT, or EMDR should be universally preferred. Match the protocol to patient preference, local clinician competence, trauma presentation, and feasibility, while preserving delivery of a structured evidence-based treatment rather than substituting nonspecific supportive counseling.

Medication decisions
Do not use benzodiazepines as PTSD treatment
Pharmacotherapy should not displace trauma-focused psychotherapy when an evidence-based psychotherapy is available.
Avoid initiating benzodiazepines to treat PTSD, including for PTSD-related anxiety or sleep disturbance. VA guidance recommends avoiding benzodiazepines in patients with PTSD symptoms because they are ineffective for core PTSD symptoms and do not improve PTSD-related sleep dysfunction. ccjmccjmJoint Clinical Practice Guideline on Benzodiazepine Tapering: Considerations When Risks Outweigh Benefits | Journal of General Internal Medicine | Springer Nature Link
Benzodiazepine exposure carries a clinically important tradeoff in PTSD: reported associations include increased substance use, depression, aggression, greater PTSD severity, and reduced efficacy of trauma-focused psychotherapy. These concerns are especially relevant when a patient is being referred for CPT, PE, or another trauma-focused protocol. ccjmccjmJoint Clinical Practice Guideline on Benzodiazepine Tapering: Considerations When Risks Outweigh Benefits | Journal of General Internal Medicine | Springer Nature Link
When a patient is already receiving a benzodiazepine, do not abruptly stop it solely because PTSD is diagnosed. Reassess indication, duration, co-occurring substance use, depression, aggression, and readiness for a structured taper; use a benzodiazepine-tapering guideline when risks outweigh benefits. ccjmccjmJoint Clinical Practice Guideline on Benzodiazepine Tapering: Considerations When Risks Outweigh Benefits | Journal of General Internal Medicine | Springer Nature Link
Nightmares and sleep fragmentation should prompt a targeted evaluation rather than reflexive sedative prescribing. Doxazosin has limited and heterogeneous evidence for trauma-related nightmares, with mixed randomized-trial findings; it may be considered only as an adjunct within a comprehensive treatment plan, not as a replacement for first-line psychotherapy.

Follow-up
Monitor engagement, symptom trajectory, and suicide risk through treatment
Follow-up should determine whether the patient is receiving an adequate trauma-focused intervention and remains safe enough to continue it.
At each early treatment contact, reassess suicidal ideation, treatment attendance, avoidance-driven disengagement, substance use, and barriers to completing the selected protocol. In a population-based cohort of 847,217 veterans with an initial PTSD diagnosis, initiation of CPT or PE was associated with lower suicide risk after adjustment for measured clinical and demographic characteristics; this supports active efforts to connect eligible patients to these therapies rather than passive referral alone. JAMAJAMAClinical Implications of Trauma-Focused Therapy for Veterans
Use a consistent symptom measure such as the PCL-5 at clinically meaningful intervals during and after treatment, but interpret improvement alongside functioning and clinician assessment. In one treatment-seeking military and veteran sample, 44.7% achieved CAPS-5 remission after treatment while 48.9% no longer met probable PTSD on PCL-5, illustrating that symptom-screen status and structured-interview remission can diverge. PubMedPubMedA comparison of the CAPS-5 and PCL-5 to assess PTSD in military and veteran treatment-seeking samples
Escalate the treatment plan when the patient cannot access the selected evidence-based psychotherapy, repeatedly disengages, develops worsening suicidality, or has diagnostic uncertainty despite serial self-report scores. Address modifiable access barriers because therapist capacity, particularly in rural and underresourced settings, can reduce reach of CPT and PE. JAMAJAMAClinical Implications of Trauma-Focused Therapy for Veterans
Continue to measure symptoms after treatment completion when relapse, residual symptoms, or functional impairment remain clinically relevant; PCL-5 is used for assessment of treatment effectiveness.

For patients considering novel interventions such as MDMA-assisted psychotherapy, explain that the relationship of studied protocols to currently recommended trauma-focused psychotherapies remains unclear; do not substitute investigational approaches for established first-line care.

Common questions
Can a PCL-5 score diagnose PTSD?
No. PCL-5 is useful for symptom quantification and treatment monitoring, but published probable-PTSD cutoffs range from 23 to 49 and agreement with CAPS-5 is incomplete. Confirm clinically important diagnoses with structured assessment when needed. PubMed+1PubMedThe Posttraumatic Stress Disorder (PTSD) Checklist for DSM–5 - PMCPubMedA comparison of the CAPS-5 and PCL-5 to assess PTSD in military and veteran treatment-seeking samples
Should trauma-focused psychotherapy be deferred until all comorbid symptoms resolve?
Not routinely. Identify and stabilize immediate barriers to safe participation, such as imminent suicide risk or uncontrolled intoxication, while maintaining a plan for PTSD-directed treatment. Comorbidity alone should not default the patient to nonspecific care. nice org uknice org uk[PDF] PTSD (update) guideline - NICE
