First, this manual will focus on the concept of ‘personality’ and the theoretical background of the WPI. Following this, the development, norms, the reliability and validity of the questionnaire will be discussed. Finally, the application of the questionnaire, the interpretation of the results and which conclusions one can draw from the results will be elaborated on.
