How to Monitor NSSI Risk After a Suicidal Crisis
How should clinicians follow adults after a recent suicide attempt or severe suicidal ideation to identify risk of nonsuicidal self-injury?
Adults discharged after a suicide attempt or severe suicidal ideation can develop nonsuicidal self-injury during follow-up, and the most useful signals may be day-to-day psychological changes rather than baseline diagnosis alone. This guide applies to high-risk adults in post-crisis care and focuses on the monitoring signals this study linked most closely to later NSSI.
-
Identify the high-risk follow-up population
Apply this monitoring approach to adults who have had a suicide attempt or a severe suicidal ideation episode requiring urgent care in the past month. The study was conducted in this specific post-crisis adult population, so its workflow is most relevant to patients being followed after emergency or outpatient stabilization.
-
Set up repeated structured check-ins
Use repeated follow-up contacts that directly ask about recent self-harm-related thoughts and affective state. In the study, ecological momentary assessment was delivered by smartphone with 1 daily notification between 9:00 AM and 9:00 PM, drawing 2 to 4 questions per day from a larger item pool over 12 months, and the authors conclude that repeated monitoring through digital tools or structured follow-up may improve post-crisis assessment.
-
Ask directly about desire to self-harm
Include a direct repeated question about desire to self-harm because higher mean desire to self-harm was the clearest signal linked to later NSSI. Participants who engaged in NSSI had higher DSH during follow-up, the mean DSH on the day of NSSI was 59.00 on the study's 0 to 100 scale, and the mean DSH measure showed acceptable discrimination for NSSI with an AUC of 0.743.
-
Track passive suicidal ideation separately from active ideation
Do not collapse all suicidal ideation into a single undifferentiated item during follow-up. In this study, passive suicidal ideation, not active suicidal ideation, distinguished the NSSI group, with higher passive SI in those who engaged in NSSI and a positive passive SI slope across follow-up in that group.
-
Monitor negative affect with attention to agitation-related symptoms
Assess negative affect repeatedly, because the NSSI group had higher negative affect over follow-up than the non-NSSI group. Pay particular attention to restlessness, which was the specific emotion significantly higher in the NSSI group, and also note that anxiety increased over time in the NSSI group while restlessness, sadness, and hopelessness decreased.
-
Include selected interpersonal experiences in follow-up review
Ask about negative interpersonal experiences, especially feelings of lack of independence, as part of follow-up review. Overall interpersonal problems were not associated with NSSI in the mixed-model analysis, but lack of independence was higher in the NSSI group and the authors recommend monitoring it alongside DSH, passive SI, restlessness, and anxiety.
-
Escalate concern when these signals cluster
Treat the combination of DSH, passive SI, and elevated negative affect as a higher-risk pattern for NSSI during follow-up. The study's clinical implications specifically highlight patients with agitated depression features such as sadness, hopelessness, agitation, or anxiety and/or interpersonal problems as more vulnerable to NSSI after hospitalization, and the conclusion states that adults engaging in NSSI after discharge should be closely monitored for suicide prevention.
Clinical Considerations
- These findings apply to a specific cohort of high-risk adults after a recent suicidal crisis and should not be generalized to adolescents, young adults, community samples, or the broader NSSI population.
- Only 15 participants reported NSSI during follow-up, so precision is limited.
- Mean DSH had acceptable discrimination but low specificity, so it can flag many patients who do not go on to engage in NSSI.
- The study did not find that intraindividual variability in DSH, suicidal ideation, negative affect, or interpersonal problems predicted NSSI.
Bottom Line
After a suicidal crisis in adults, repeatedly monitor desire to self-harm, passive suicidal ideation, and negative affect, especially restlessness, anxiety, and lack of independence, because these were the signals most closely linked to later NSSI.
