Guidelines

Prevention and intervention are important but they need to be evaluated in order to provide indicators of their effectiveness and to find the keys for improvement. It is essential that the headteachers help the educational community to plan the system to evaluate the actions in order to ascertain whether they have served to reach the planned objectives as regards the line of prevention, the action with pupils at risk or the intervention with pupils involved in bullying (victims or aggressors). The evaluation, although performed at the end of the process, must be designed from the beginning. The main methodological aim should be to follow the principles of evidence-based practices. It is desirable that the evaluation is carried out with instruments validated prior to the development of the intervention, also among pupils that will develop the intervention (known as experimental group) and among pupils that will not develop the intervention (known as control group). The purpose of this is to determine the changes that occur due to the intervention program.
