Using genetics and smartphone data to predict and prevent repeat suicide attempts

Prevention of Suicidal Behavior Through Therapeutic Interventions Guided by Digital Phenotype and Pharmacogenetics: The SMARTomicS Study Protocol

Observational Instituto de Investigación Sanitaria de la Fundación Jiménez Díaz · NCT07422090

This project will try to combine genetic tests and people’s digital behavior to predict which individuals with a past suicide attempt may be at higher risk of trying again.

What this trial studies

This is a retrospective, multi-site observational cohort that will merge genomic and metabolic profiling with digital phenotyping and clinical records in people with a lifetime history of suicide attempt. Participants (age 12 and up, with parental consent for minors) will be recruited from outpatient mental health clinics, emergency departments, and short-stay hospital units and will provide genetic samples plus consent for extraction of digital data such as Google Takeout. Investigators will link omics, prescription changes, electronic health record data, and standardized suicide-rating scales (e.g., C-SSRS) to develop predictive algorithms for suicidal behavior. Data quality checks and representativeness will be performed using hospital records and national statistics.

Who should consider this trial

Good fit: People aged 12 and older with at least one prior suicide attempt who can provide a genetic sample and give informed consent (parental consent required for ages 12–17) are the ideal candidates.

Not a fit: Those who cannot provide a blood/genetic sample or who do not consent to digital data extraction are unlikely to benefit from participation or from the predictive results.

Why it matters

Potential benefit: If successful, this approach could help clinicians identify people at higher risk of repeat suicidal behavior earlier and tailor treatments using genetic and digital signal information.

How similar studies have performed: Prior work has found some promising genetic and digital signals related to suicide risk, but fully integrated predictive models combining omics and detailed digital phenotypes remain largely experimental.
