Protocol - PTSD Symptoms, Self-report - DSM 5
Protocol Name from Source:This section will be completed when reviewed by an Expert Review Panel.
The PTSD Checklist (PCL-5) for The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is a 20-item self-report measure that assesses DSM-5-based criteria for PTSD symptoms. Each item is rated on a 5-point Likert-type scale (0 = Not at all; 5 = Extremely) that indicates how much the participant has been bothered by an identified "worst" stressful event in the past month.
Summary of the PTSD Checklist (PCL) for DSM-5
The PTSD Checklist (PCL) for DSM-5 includes 20 items that capture:
Repeated, disturbing, and unwanted memories and/or dreams
Feeling and/or acting as if the experience was happening again
Feeling upset and/or having physical reactions when reminded of the experience
Avoiding memories and/or external reminders of the experience
Trouble remembering parts of the experience
Strong negative beliefs and/or negative feelings
Blaming yourself or others for the experience
Loss of interest in activities and/or feeling cut off
Trouble experiencing positive feelings
Irritable behavior, feeling jumpy, and/or being "superalert"
Each item is scored on a 5-point Likert scale (0 = Not at all; 4 = Extremely) indicating how much the participant has been bothered by the event in the past month. A total symptom severity score can be obtained by totaling the scores of the 20 individual items. Preliminary validation work suggests a cut-off score of 38 for PTSD screening.
DSM-5 symptom cluster severity scores can be calculated according to the following:
- Cluster B - sum items 1-5
- Cluster C - sum items 6-7
- Cluster D - sum items 8-14
- Cluster E - sum items 15-20
A provisional PTSD diagnosis can be made by counting each item rated as 2 ("Moderately") or higher as a symptom endorsement, then following the DSM-5 diagnostic rule, which requires at least 1 item from cluster B (questions 1-5), 1 item from cluster C (questions 6-7), 2 items from cluster D (questions 8-14), and 2 items from cluster E (questions 15-20).
Interpretation of the PCL-5 should be made by a clinician.
Change scores for PCL-5 have not yet been documented, but it is expected that reliable and clinically meaningful change will be in a similar range to the scores established for the PCL for DSM-IV (reliable > 5; clinically meaningful > 10).

Mode of Administration
A change in the numerical rating scale combined with an increase from 17 to 20 items means that The PTSD Checklist (PCL-5) scores are not interchangeable with scores based on PCL-4 for The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV).
This measure includes both the DSM-IV and DSM-5 versions of the PTSD Checklist. The PhenX PTSD Working Group anticipates that scientific demands will dictate that researchers typically collect data in accordance with the most recent PTSD criteria and will use the DSM-5 version of the protocol. However, under special circumstances (e.g., when adding to older, existing data sets), researchers may decide to use the DSM-IV version instead.

DefinitionA questionnaire to assess post-traumatic stress disorder (PTSD) symptoms.
This measure can be used to screen for post-traumatic stress disorder (PTSD) and as a quantitative measure of PTSD symptom severity.
The PTSD Checklist (PCL-5) for The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is based on the PCL-4 for The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), a brief, self-administered, widely used measure to assess post-traumatic stress disorder (PTSD) symptoms that demonstrates good psychometric properties. The PTSD Checklist for DSM-5 provides a quantitative measure of PTSD symptom severity that aligns with the revised diagnostic criteria.
