Objectives: This study examined how depression, anxiety, and sleep items from the Neurobehavioral Symptom Inventory (NSI) predict results from longer inventories.
Method: This was a retrospective review from 484, predominantly male (96.1%) Veterans, mean age 29.7 years, who underwent brief neuropsychological screening during a comprehensive, multidisciplinary evaluation for mild traumatic brain injury (TBI). Participants completed the NSI, insomnia severity index (ISI), and hospital anxiety and depression scale (HADS).
Results: OVERALL,: 97.1% who endorsed "severe"/"very severe" anxiety on the NSI had significant anxiety on the HADS; 85% reporting "severe"/"very severe" depression on the NSI, had significant depression on the HADS; and 97.7% reporting "severe"/"very severe" sleep problems on the NSI, had significant sleep difficulties on the ISI.
Conclusion: Close correspondence between "severe"/"very severe" symptoms on the NSI and lengthier checklists suggests additional checklists may be eliminated and individuals can be referred for mental health treatment. NSI reports of "mild"/"moderate" require further screening.
