The impact of a staff-training program on knowledge and confidence in supporting people with intellectual disabilities (ID) at the time of bereavement was examined. Thirty-three staff members from a Dublin, Ireland-based ID support service participated in the study. Both the training (n = 17) and control (n = 16) groups completed measures of confidence at the beginning and end of a 4-week period around supporting service users through a bereavement survey designed for the study, as well as the Staff Support and Satisfaction Questionnaire. During this interval, the training group completed a two-day training focusing on exploring existing strategies for supporting service users and providing staff with additional skills. Staff members also completed a survey of knowledge at the outset of the study. Over the 4 weeks, there was a significant increase in confidence among the training group, with no comparable changes in the control group. However, as predicted, neither group showed significant changes in general support or job satisfaction. The findings suggest that the training significantly increased staff members' confidence in their ability to respond to the challenges of support service users during bereavement. The study's findings also have a number of practical implications, including the need to provide appropriate support for staff.
