Who could benefit from this research
✓Could help
Adults (21+) with anorexia nervosa who are willing to share real-time data via digital devices over time.
✕Less likely to help
Participants not experiencing anorexia nervosa or those unwilling to engage in intensive, real-time data collection may not benefit.
What this research studies
We will track adults with anorexia nervosa in real time to see how feelings like anxiety and arousal connect with SI and SA. Using smartphones or wearable sensors, we’ll collect moment-to-moment data on emotions, symptoms, and behavior to map dynamic risk patterns. The researchers aim to identify which factors most strongly predict suicidal thoughts or actions so future prevention and treatment can be more precisely targeted.
Why it matters
Potential benefit: If successful, the study could reveal when and why suicide risk rises in people with anorexia nervosa, guiding personalized prevention strategies.
How similar studies have gone: Past work has shown that dynamic models can reveal linking patterns between mood, symptoms, and risk, with this study extending those methods to anorexia nervosa.
