JASPer-MH: Jointly Assessed Scalable Phenotypes for Mental Health - Mental health among young adults represents a public health crisis, requiring more efficient and precise means of understanding illness trajectories in the general population. Such models could provide opportunities for early identification and intervention for mental illness during the period of adolescence to young adulthood, as youth navigate key psychosocial milestones and neuropsychiatric illness becomes entrenched. Work by the investigators and others has demonstrated the utility of electronic health records (EHR) for developing risk stratification models for psychiatric outcomes. Yet, the investigators and others have also shown that the diagnostic codes available in EHR are insufficient to reliably predict the evolution of psychopathology over time. As such, RFA MH-23-105 seeks strategies to augment EHR-based models to efficiently capture signatures that may improve clinical prediction. Among the broad range of potential measures, brief batteries that capture dimensional traits, including quantitative symptoms and cognition, are at the core of evidence- based, developmentally relevant psychopathology frameworks and are consistent with the consensus that clinical staging must be approached through a transdiagnostic lens. Variation in such traits is not well-captured by standard EHR data but represents an important aspect of neurodevelopment and its relationship to clinical and functional outcomes. This study proposes to integrate remotely-delivered cognitive tasks and brief symptom inventories to enhance prediction of prospective outcomes among transition age youth. Specifically, it will apply methods developed by the investigators to a cohort of N= 10,000 individuals age 18-20 identified from EHR in the Mass General Brigham Health Care system and assessed prospectively every 6 months for 2 years. Aim 1 will identify, enroll, and retrospectively characterize this cohort, extending EHR codes with validated NLP methods to characterize dimensional psychiatric symptoms and cognitive functioning retrospectively for up to 10 years, using data censored 6 or 24 months prior to baseline to predict current status. Aim 2 will collect enhanced phenotyping (neurocognitive and self-report psychiatric and psychosocial functioning data) on this cohort every 6 months and apply both standard and novel interpretable machine learning methods to derive predictors of 180-day psychiatric outcomes. Aim 3 will apply interpretable machine learning methods to determine the value of enhanced phenotyping over EHR data alone for 24-month outcomes . We hypothesize that adding these low cost, low burden phenotypes will improve the performance of models predicting longitudinal neuropsychiatric outcomes in a manner that can be translated across health care systems with diverse populations.
