Grief in Daily life Archive (Grief-ID Archive)

The archive complies with Findable, Accessible, Interoperable, Reusable (FAIR) research guiding principles and provides extensive metadata corresponding to each principle. Researchers are encouraged to reuse and contribute data to the Grief-ID archive, thereby furthering our understanding of grief in daily life. Data Collection Version 1.0 of the archive includes 315 participants and 22,050 EMA measurement points.

On average, participants responded to 43.77 ESM notifications in total, with the median being 50, on a scale from 1 to 70, which reflects an overall compliance rate of 71%. Individuals aged 18 years and above were eligible to participate. People diagnosed with a psychotic disorder or those reporting suicidal ideation, assessed at baseline, were excluded from participation.

The studies included in Version 1.0 consisted of three distinct phases of data collection. First, the initial baseline measures included questions assessing sociodemographic, loss characteristics, measures of psychopathology, and other measures. Second, the ESM phase was conducted using the Avicenna application (Avicenna Research, 2024).

Participants rated the intensity of PGD symptoms and contextual factors five times a day, for a period of 14 days. Third, the final phase of the study was conducted following the ESM phase. In this phase, psychopathology symptoms were assessed in a manner consistent with that employed in phase one.

Differences in recruitment strategies and inclusion criteria between the three different projects are outlined in supporting information.
