The dose effect of a group intervention for bereaved HIV-positive individuals
Group interventions for health-related issues such as cancer and HIV infection have demonstrated effectiveness and are widely used, yet the question of dosage for group interventions has received little attention. This study examined the longitudinal effect of varying doses of a group intervention for coping with AIDS-related loss in 158 HIV-positive women and men. Grief and psychiatric distress were assessed at baseline, postintervention, and at 4-, 8-, and 12-month follow-ups. Longitudinal data analyses using mixed models were conducted to examine differences in outcome by dosage. Results show that both grief and psychiatric distress were inversely related to dosage across time, indicating that the higher the intervention exposure, the greater the reduction in distress and grief. The clinical significance of change by dosage was also considered. © 2006 APA, all rights reserved.
