Exploring Differences in Presentation and Treatment Outcomes Between Black and White American Adults With Prolonged Grief Disorder.

Prolonged grief disorder (PGD) is a condition of persistent, intense grief and PGD-targeted psychotherapy (PGDT) is an efficacious treatment. This study aimed to compare participants with PGD who self-identified as Black versus White, with respect to baseline features and response to PGDT. We performed a secondary data analysis of 55 Black and 455 White adults from two randomized clinical trials. Racial differences in baseline features were examined using Chi-squared and T-tests. We compared assessment completion and treatment response rates (PGDT vs. no PGDT) by race and evaluated posttreatment self-reported measures using linear models. There were racial differences in the cause of death, relation to the deceased, and taking comfort in religion. Black participants had similar ratings to their counterparts on impairment and grief severity at baseline. However, they had higher scores on a baseline measure of typical grief-related beliefs. Both racial groups had significantly greater response rates to PGDT than the comparison treatment. Similarly, PGDT resulted in lower posttreatment impairment than the comparison treatment for both racial groups. However, only the White participants had a difference in posttreatment grief severity between the treatment groups. This study supports the idea that PGD characteristics are similar in Black and White treatment seeking individuals, and that Black and White participants display improvement in response to PGDT.
