Sogn and Fjordane county community-based injury prevention: evaluation design

The Sogn and Fjordane Injury Prevention Programme is a community-based research and demonstration project located in the Sogn and Fjordane county (S&F county) in Western Norway. The aim of the project is: (i) to further effective intervention; (ii) to be cost-effective; (iii) to provide information about local community based injury intervention. Liaison groups on injury prevention will be organised in 24 communities participating in the project. Starting 1 April 1993 they will be supplied with local specific injury rates obtained from the all-injury registration of the National Injury Surveillance System. The intervention design includes feedback of three types of information: (1) home and traffic injury rates; (2) sports, occupational, school, and outdoor injury rates; (3) both (1) + (2). The liaison groups will be asked to concentrate their activities only on the information-related injury areas. The hypothesis is that the results will be information-related. The intervention protocol will last for two years, until 1 April 1995. Evaluation will be based on a hypothetical causal intervention model. The model includes three groups of independent influences, two groups of mediator attributes, and desired end-result. A variety of data sources will be used including national and local data sources, two cross-sectional surveys on awareness, knowledge, behaviour and attitudes, interviews, observations, and self-reports from individuals. A mixed-model ANOVA will be used to test the main information-related effects. A combination of multivariate analytical methods will be used to test the hypothesised causal intervention model.
