In the early 1990s one of the great medical research exercises of modern times took place. It became known as the Nun Study. Some 700 American nuns, all members of the School Sisters of Notre Dame in the United States, agreed to allow their records to be accessed by a research team investigating the process of ageing and Alzheimer’s Disease. At the start of the study the participants were aged between 75 and 102.
What gave this study its unusual longitudinal scope is that in 1930 the nuns, then in their twenties, had been asked by the Mother Superior to write a brief autobiographical account of their life and their reasons for entering the convent. These documents were now analysed by the researchers using a specially devised coding system to register, among other things, positive and negative emotions. By annually assessing the nuns’ current state of health, the researchers were able to test whether their emotional state in 1930 had an effect on their health some sixty years later. Because they had all lived a very similar lifestyle during these six decades, they formed an ideal group for testing hypotheses about the relationship between emotional attitudes and health.
