Abstract
Prolonged Grief Disorder (PGD) has been formally included in the ICD-11 and the DSM-5-TR recently. So far, little research has been conducted that evaluates the validity of PGD criteria per ICD-11 and DSM-5-TR. To assess the test-criterion validity of PGD, aimed to establish if PGD symptoms per ICD-11 and DSM-5-TR criteria predict changes in QoL. A sample of 276 bereaved adults (mean age 54 years, 92% female) filled in a survey at baseline and 6 (n = 142) and 12 (n = 135) months later. The Traumatic Grief Inventory-Self Report Plus was used to measure the independent variables ICD-11 and DSM-5-TR prolonged grief symptoms. The European Health Interview Survey - Quality of Life 8-item index was used to measure the dependent variable QoL. Two simple linear regression analyses demonstrated that T1 ICD-11 and DSM-5-TR prolonged grief symptoms related negatively to T1 QoL, supporting concurrent test-criterion validity. Four hierarchical regression analyses demonstrated that T1 ICD-11 and DSM-5-TR symptoms significantly predict QoL at T2 and T3 whilst controlling for T1 QoL, supporting predictive test-criterion validity. ICD-11 and DSM-5-TR prolonged grief symptoms are negatively associated with quality of life. ICD-11 and DSM-5-TR prolonged grief symptoms predict lower quality of life scores at T2 and T3.
