What's Time Got to Do With It?: A Time-Informed Approach to Longitudinal Research With Trauma Affected and Bereaved Populations.

This paper outlines a new approach to using participants' self-identified temporal triggers to center data collection around meaningful time periods as it pertains to coping with loss and trauma. We describe the utility of ecological momentary assessment and wearable technology as tools for time-informed data collection; and provide a study protocol for a recent study in which we paired these approaches to gather data from adult respondents who had lost a loved one. Data collection included two phases: a baseline phase and a target date phase. The target date phase was centered around the participant's self-identified temporal trigger. Several lmitations to this mode of data collection are disucsed. The overall approach is client centered and more accurately captures the lived experiences of individuals coping with loss and trauma. Data of this kind will begin to highlight the psychological and physiological impacts of anniversary dates among survivors of trauma and loss.
