This report provides an evaluation of the Austrian guidelines that were introduced in 1987 as a natural experiment. Methods: The impact of the guidelines was tested by applying an autoregressive integrated moving average (ARIMA) model and a linear regression model. In addition to a nationwide evaluation, Austria was divided into three areas according to regional differences in coverage rates of the collaborating newspapers and the impact of the intervention was tested for each area separately.

In order to test intermediate impacts, also quantitative and qualitative changes in media reporting after the introduction of the guidelines were analysed.
