[en] The ATPA scales of Kenyon have become a classical instrument for the measurement of motives and attitudes. This article gives an overview of psychometric data concerning the German adaptations of this method. Using a study of young members of sports clubs (n=2133 pupils in Luxembourg, n=344 pupils in Germany) the suitability and validity of a short form of these scales are also examined. In general the item-metrical analyses, factor analyses as well as inter-correlation analyses show that the results of this short form of the ATPA-D-scales are satisfying. The findings prove the economic applicability of the scales for sport-science and motivation-oriented research studies.
