Abstract

This dissertation examines the temporal dynamics of suicidal ideation in daily life using real-time assessment methods, including actigraphy and ecological momentary assessment (EMA). Suicidal ideation can be highly variable, and increased insight into these fluctuations can aid us in understanding how an individual may transition into moments of heightened suicidal ideation in real-time. Further, it has been proposed that variability in itself may serve as a phenotypic marker for increased suicide risk. Hence, obtaining a better understanding of the correlates and predictors of this variability is important for improved risk detection.
