Investigates what people are prepared to do in the way of disaster preparation, and examines how these assessments may be related to personal factors and attitudes. Draws on a theoretical model of the area, developed in a previous study using a qualitative grounded theory approach. Surveys 925 persons representative of the Swedish population between the ages of 16 and 74. Data were collected in a postal questionnaire. Shows that the preparations for disasters which had been carried out by the greatest number were installation of smoke detectors, participating in practice at school or work, and learning first aid. The least performed preparations included joining a voluntary organization or training programme, stocking up with tinned food at home, taking extra insurance, and learning how to deal with psychological crisis reactions. Finds considerable subgroup differences; and that the two key dimensions of the model - sense of personal meaningfulness and societal commitment - account for the differences. Suggests actions to be taken by the Swedish authorities.
