Methods: A mixed methods approach was taken, combining quantitative epidemiological study of suicide using Office for National Statistics (ONS) Public Health Mortality Files with qualitative retrospective case study analysis using coroner’s records and local audit database. All completed suicides (and some systematically selected open verdicts) in people aged 75 years and over occurring in Cornwall between 2006 and 2010 were included.A questionnaire survey of rural community dwelling people aged 75 years and over (n = 49) in a part of Cornwall was also carried out to identify the main sources of stress associated with ageing in the local area.
