Harmful or helpful? A systematic review of how those bereaved through suicide experience research participation

Background: Many of the bereaved through suicide are interested in participating in postvention studies. However, there is a contradiction between the positive experiences of research participation and concerns raised by ethical boards. Aims: To review studies on the experience of research participation by those bereaved through suicide, including initial contact with the study and its short- and long-term impacts. Method: Systematic searches in Embase, Medline, PsycINFO, as well as Google Scholar identified 12 papers reporting on 11 studies. Results: The majority (73–100%) of study participants evaluated participation positively, and would recommend it to others (90–100%), as it was related to altruism, social support, and personal growth. A minority experienced participation as negative (2–10%) or upsetting (5–22%) due to feelings of guilt or painful memories. However, having a painful experience does not preclude seeing it as helpful. Limitations: Most studies concerned face-to-face psychological autopsy studies, and only two studies included a control group. Conclusion: Research applying standardized measures may enhance our understanding of the factors germane to (non-)participation and to the likelihood of a positive/negative research experience. Vigilant recruitment and providing optimum care for participants are indicated. Further research may continue to improve participant safety and the research design of suicide bereavement studies.
