Summary
This study provides average Neurobehavioral Symptom Inventory (NSI) and PTSD Checklist for DSM-5 (PCL-5) scores for active duty service members. These normative data help clinicians interpret TBI-related symptoms within demographic contexts.
Area of Science:
- Neuroscience
- Military Health
- Psychiatry
Background:
- Traumatic brain injury (TBI) is prevalent among service members (SMs).
- Current military treatment facilities lack normative data for TBI-related symptom assessment.
- Gauging patient-reported symptoms against established benchmarks is challenging.
Purpose of the Study:
- To establish normative scores for the Neurobehavioral Symptom Inventory (NSI) and the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5).
- To provide average scores for active duty SMs based on demographic variables.
- To aid clinicians in interpreting TBI symptom severity.
Main Methods:
- Collected initial NSI and PCL-5 survey data from SMs at a military TBI outpatient clinic.
- Analyzed survey data using demographic information including age group, gender, grade, and race.
- Calculated average scores for symptom inventories.
Main Results:
- Developed four normative tables presenting average NSI and PCL-5 scores.
- Tables are stratified by demographic groupings: Age Group/Gender/Race and Grade/Gender/Race.
- Provides a benchmark for symptom comparison.
Conclusions:
- Clinicians can utilize these normative scores to contextualize individual SMs' NSI and PCL-5 results.
- Healthcare administrators can use the data for resource allocation and treatment planning.
- Facilitates more accurate assessment and management of TBI in military populations.
