The main attention is given to introduction of a new questionnaire for both elementary and high schools. The questionnaire development, outcome structures, implementation, assessment, and interpretations based on national norms are described in detail.
In conclusion, various interventions are suggested. The questionnaire is also available in an electronic version, which allows quick assessment of data and a standardized outcome for its users.
