结局指标
主要结局
Change in Prolonged Grief Disorder symptom severity as assessed by the PGD-12
时间窗: Weekly for 12 weeks
Change in PGD symptom severity will be measured by using Prolonged Grief-13 (PGD-12), a self-rated scale consisting of 12 items. For this study, we have added an additional item inquiring about loneliness to be congruent with DSM-5-TR criteria and SCIP. This 5-point Likert-type of measurement tool evaluates the intensity and severity of the PGD. The validity and reliability of the PGD-12 was tested and validated in previous studies.
Change in Prolonged Grief Disorder severity as assessed by Structured Clinical Interview for PGD
时间窗: Every 4 weeks for 8 weeks
The IOS is a self-reported pictorial tool use to measure the subjectively perceived closeness of a relationship. The tool asks respondents to select one of seven pairs of increasingly overlapping circles that best represents their relationship with another, with more overlap signifying a closer relationship. This scale possesses good reliability, with (α = .93) for the entire sample, (α = .87) for family, (α = .92) for friendship, and (α = .95) for romantic relationships. Test-retest reliability shows similar findings, with (α = .83) for the entire sample, (α = .85) for family, (α = .86) for friendship, and (α = .85) for romantic relationships.
次要结局
- Change in strength of subjectively perceived closeness of a social relationship as measured by the Inclusion of the other in the Self (IOS) Scale(Every 4 weeks for 12 weeks)
