About

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.
