Detailed Description
Objectives of the project:
The overall aim of this project is to develop three culturally sensitive measures of grief for use in Switzerland, China and Japan. Three sub-aims are described below:
Substudy 1: Development of the questionnaire Substudy 2: Psychometric Validation of the questionnaire Substudy 3: Relationship between emotional expression and grief The relationship between grief and the expression of emotion will be explored within and across the three cultures.
Outcomes of the project:
Sub-study 1:
- Three new culturally sensitive versions of a Prolonged grief disorder measure (IPGDS) 1) Swiss 2) Japanese 3) Chinese versions: the structure and item content of this measure
Beta draft of a mobile app version of the IPGDS questionnaire
Sub-study 2:
Psychometric properties of the IPGDs: specific outcomes including statistical confirmation of the reliability (interrater reliability, test/retest, internal consistency) and validity (criterion, content validity, construct validity) of the IPGDs
Sub-study 3:
- Identification and documentation of emotional expression differences in Chinese, Japanese and Swiss culture that may impact on assessment of grief and could inform clinical assessment procedure.

Time Frame |
---|---|---|
Development and validity of the International Prolonged Grief Disorder Scale (IPGDS), A questionnaire
Time Frame: 24 months
|
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.

Emotional control beliefs about grief scale (ECBG)
Time Frame: 36 months
|
Emotion Control Beliefs scale adapted for grief: Emotion Control Values on Grief was developed from the existing Emotion Control Values (ECV: Mauss et al., 2010) and adapted to the emotion control of grief. It comprises nine items: (1) "People should not cry a lot when grieving"; (2) "It is helpful to cry a lot when grieving"; (3) "People should not express positive emotions when grieving"; (4) "People should not express negative emotions when grieving"; (5) "It is appropriate to express negative emotions when grieving"; (6) "It is appropriate to express positive emotions when grieving"; (7) "People in general should control their emotions more when grieving"; (8) "It is helpful to express negative emotions when grieving"; (9) "It is helpful to express positive emotions when grieving". |

Emotion Regulation Questionnaire (ERQ)
Time Frame: 36 months
|
Emotion Regulation Questionnaire The 10-item Emotion Regulation Questionnaire (ERQ) includes two dimensions: cognitive re-appraisal and expression suppression (Gross & Jone, 2003).
Each item is rated from from 1 (strongly disagree) to 7 (strongly agree).
A higher score indicates a higher frequency to use emotion regulation strategies.

Emotional regulation repertoire(ERR)
Time Frame: 36 months
|
Emotion Regulation Repertoire The Emotion Regulation Repertoire (ERR) was developed to assess how close others respond to participants' intense feelings and emotions.
For each network member listed in the Social Net-work Index, participants choose from a list of 19 items how the particular network members usually or most often responds to their strong emotions ("This person _____ when I have strong feelings.").
Regulation strategies included in the list comprise, amongst others, advises me, understands me, and vents with me.
In addition, participants will indicate how their deceased loved one used to re-spond to their emotions.

The social network inventory
Time Frame: 36 months
|
Social Network Index The Social Network Index (SNI) was developed and adapted from the existing Social Network Index (SNI: Cohen et al., 1997) in order to tailor it towards social network characteristics of be-reaved individuals.
It comprises fourteen items regarding participants' network members including family members, friends, grief support group members, and online contacts.
Participants are asked to identify how many network members they feel close to (0-7), and which one of their network members they see or talk to at least once every two weeks (by indicating thei first name and initial for last name).

Idiographic Interview task
Time Frame: 36 months
|
Idiographic Interview task (Diminich & Bonanno, 2014) Participants will discuss their relationships with the deceased and current attachment figure in the context of conflict and intimacy will be conducted. Self-reported affect, emotional word use, and facial coding will be measured and compared between groups. Participants will be informed that there were no correct answers and that interviewers will be interested in what their particular experiences might be like. Participants will be asked to recall and recount in a fixed order, specific events in which there is: conflict with the deceased; intimacy with the deceased; conflict with other current attachment, and intimacy with other current attachment. The interviewer will halt participant's recounting of the event after 3 minutes. |

Positive and Negative Affect Scale
Time Frame: 36 months
|
Positive and Negative Affect Scales After each interview topic, participants will be asked to rate using a 5-point Likert scale from 1(very slightly) to 5 (extremely) the extent to which they feel a number of emotions using the Posi-tive and Negative Affect Schedule (PANAS: Watson et al., 1988).
The PANAS is composed of two scales, 10 items for positive emotion (interested, excited, strong, enthusiastic, proud, alert, inspired, determined, attentive, active) and 10 items for negative emotion (distressed, upset, guilty, scared, hostile, irritable, ashamed, nervous, jittery, afraid).
