研究概览
简要总结
The overall project includes three sub-studies. Sub-Study I aims to develop the content of a new cultural sensitive grief questionnaire (International Prolonged Grief Disorder Scale, IPGDS Killikelly and Maercker, 2018) through interviews and focus groups with key (expert) informants and bereaved participants from Japan, Switzerland and China. The content will be piloted in paper and mobile app format. Sub - Study II aims to validate the new paper and mobile questionnaire in 200 participants from each culture using a battery of questionnaires and psychometric assessment. Sub-Study III will explore the relationship between grief and the cultural expression or repression of emotion. This will involve a battery of questionnaires about emotional expression and a short idiographic interview task administered to Swiss, Japanese and Chinese bereaved participants in paper and online format.

refinement and psychometric properties of the IPGDS (International Prolonged Grief Disorder Scale): Prolonged grief symptoms will be evaluated through the ICD-11 Prolonged Grief Disorder Scale (IPGDS) (Killikelly and Maercker, 2018). This scale comprises 14 previously used items integrating the PG-13 (Prigerson, Vanderwerker and Maciejewski, 2008) and the SCI-CG (Bui et al., 2015). The participants will be requested to describe how often they had felt preoccupation, yearning and symptoms of emotional distress over the past month because of loss of a loved one, using a 5-point scale: 1 = almost never (less than once a month), 2 = rarely (monthly), 3 = sometimes (weekly), 4 = often (daily), and 5 = always (several times a day). The English, Japanese and Chinese versions of the IPGDs will be translated and back translated following standard protocol (Mollica et al., 1992). The scale will be in paper and online format and can be completed in 5-10 minutes.
