Background: The death of the Princess of Wales in 1997 was followed by widespread public mourning. Such major events may influence suicidal behaviour.
Aims: To assess the impact of the Princess's death on suicide and deliberate self-harm (DSH).
Method: Analysis, using Poisson regression, of the number of suicides and open verdicts ('suicides') in England and Wales following the Princess's death compared to the 3 months beforehand, and the equivalent periods in 1992-1996. Similar analysis on DSH presentations to a general hospital.
Results: Suicides increased during the month following the Princess's funeral (+17.4%). This was particularly marked in females (+33.7%), especially those aged 25-44 years (+45.1%). Suicides did not fall in the week between the death and the funeral. Presentations for DSH increased significantly during the week following the death (+44.3%), especially in females (+65.1%). Examination of case notes suggested that the influence of the death was largely through amplification of personal losses or exacerbation of existing distress.
Conclusions: The death of a major public figure can influence rates of suicidal behaviour. For DSH, the impact may be immediate, but for suicide it may be delayed.
