Psychometric properties of the Prolonged Grief Disorder-13 (PG-13) in bereaved Swedish parents
Open accessAbstract
This study aimed to validate the Swedish version of the Prolonged Grief Disorder-13 tool (PG-13) by examining its psychometric properties, including factor structure, discriminant and concurrent validity. The PG-13 was assessed in a sample of Swedish parents who had lost a child to cancer 1-5 years previously. The sample included 225 parents (133 mothers and 92 fathers) with a mean age of 46.02 years (SD = 8.15) and 16.0% met the criteria for Prolonged Grief Disorder (PGD). A principal component analysis was performed, and the results supported a one-factor structure of the PG-13. The PG-13 was shown to have high internal consistency and intelligible associations with concurrent psychological symptoms and grief rumination as well as with known risk factors for PGD. These results indicate satisfactory psychometric properties of the instrument, thus supporting the use of the PG-13 as a valid measure of PGD.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
