Four hundred and fourteen adolescent athletes (mean age = 16.69; SD = 1.55) participated in the second study, whereas seven hundred forty-nine adolescent team athletes (mean age = 16.43; SD = 1.69) participated in the third study. For the latter two studies, team athletes were recruited across Italy, Germany and Greece and provided data on the new team measures. Only athletes participating in the third study provided data on doping intentions. Results: The findings of the three studies supported the empirical goals of the investigation and provided evidence for the factor structure, reliability and validity of the team instruments. Furthermore, multi group findings supported the hypothesis that the new instruments would have equivalent measurement and validity characteristics across the three European countries. The conclusions focus on the conceptual and practical implications of these findings. (C) 2016 Elsevier Ltd. All rights reserved.}, language = {en} }
