Monitoring Within-Person Dynamics in Adolescents Hospitalized for Acute Suicidal Distress

This study is a multimodal, intensive longitudinal examination of the temporal unfolding of suicidal distress across complementary timescales. The integrative framework aims to identify prototypical trajectories of STBs from inpatient admission through early post-discharge. It further seeks to characterize heterogeneity in within-person processes central to ideation-to-action theories and STB-related affect regulation. Finally, the study aims to interrelate these micro-level dynamics of suicidal distress with its longitudinal trajectories on the macro-level. Within this framework, the study examines how modifiable bioregulatory factors, including sleep and physical activity, as well as clinical process factors such as therapeutic alliance, are dynamically implicated across timescales.
