Validation of items on the NDDIE and PHQ-9 associated with suicidal ideation during suicidality screening in patients with epilepsy

Loneliness in veterans: A commonality across multiple pathways toward suicidality.

“…History of TBI was assessed via a single-item question: “Have you ever been diagnosed with a traumatic brain injury, or concussion?” Responses were coded as 0 = no , 1 = yes . Single items have been used in the literature with good utility (see Kim et al, 2022; Wasserman et al, 2008).…”

“…Due to concerns over suicidal ideation and high suicide completion rates in PWE, some screeners can serve to monitor this risk as well. Both the NDDI-E and PHQ-9 have been validated in PWE to assess for suicidality, are freely available, and have been administered in electronic health record-based pre-visit protocols [54] , [55] . The NDDI-E is a 6-item screener where the 4th item can assess for suicidal ideation.…”

“…The PHQ-9 is a 9-item screener where the 9th item can assess for suicidal ideation. This item “Thoughts that you would be better off dead, or of hurting yourself” indicates potential suicidal ideation if the score is 1 to 3: responses of “several days”, “more than half the days” or “nearly every day” in the last 2 weeks [34] , [54] . If an ultra-brief depression screener that includes a suicidal ideation screen is desired, the Neurological Disorders Depression Inventory-2 (NDDIE-2) includes the suicide question and anhedonia question and had similar rates of detection of depression in a routine care sample as the full NDDI-E [40] .…”
