This dataset contains participants' responses to the outcome questionnaires at three assessment time points: T0 (pre-test), T1 (post-test) and T2 (follow-up). These data were collected via the REDCap platform.
The primary outcomes are the following:
• Grief symptoms, assessed with a French version (Cherblanc & Zech, 2021) of The Traumatic Grief Inventory (Boelen et al., 2019) at T0, T1 and T2 ;
• Depression symptoms, assessed with the Patient Health Questionnaire-9 (Kroenke & Spitzer, 2002; Kroenke, Spitzer & Williams, 2001) at T0, T1 and T2 ;
• Well-being, measured with the French version (Villieux et al., 2016) of the Flourishing Scale (Diener et al., 2010) at T0, T1 and T2.
Secondary outcomes are the following:
• Anxiety symptoms, assessed with the Generalized Anxiety Scale (Micoulaud-Franchi et al., 2016; Spitzer et al., 2006) at T0, T1 and T2 ;
• Grief coping strategies, measured with the Coping with Bereavement Questionnaire (Ryckebosch-Dayez et al., 2016) at T0 only.
• Aspects related to identity, measured with the Self-Concept Clarity (Brunot et al., 2015; Campbell et al., 1996), the Centrality of Event Scale (Berntsen & Rubin, 2006; Ceschi et al., 2009), and questions about self-continuity (Lampraki et al., 2019) at T0, T1 and T2 ;
• The subjective feelings of loneliness, measured with Loneliness Scale UCLA (De Grâce et al., 1993; Russell et al., 1980) at T0, T1 and T2 ;
• The satisfaction with the program (measured with a translated and adapted version of the CSQ-I; Boß et al., 2016) at T1.
• Monitoring of the mood, solitude feelings and grief symptoms. We monitored weekly the mood of the participants of LIVIA 2 only using a single item (“How would you describe your current mood” on a scale ranging from 0 (very bad) to 6 (very good). Moreover, we monitored weekly the grief and solitude symptoms on a scale ranging from 1 (strongly disagree) to 5 (strongly agree).
