[A new model of sportive cooperation and its evaluation by means a questionnaire].

We present in this paper the sportive cooperation as a theoretical framework for the teams' dynamics, and as an alternative to others theories, specially the sportive cohesion. This theory has a double basis: 1) The rational and utilitarist decision taking upon the personal cooperation or not, with the team's goal, based on the internal teammates interaction, and the environmental stimuli; and 2) A personal, and more stable, disposition to cooperate, despite the possibility of obtain any counterparts for this behavior. From this framework, we have build--in a three phase process--a questionnaire addressed to evaluate the sportive cooperation. The final version--composed of 15 items with standard psychometric propierties--shows two kinds of factors. First, we have two dispositional, traitlike, factors: The Conditional cooperation, and the Unconditional cooperation. Second, we have three situational factors: the Cooperation with the Coach, with the teammates, and the Cooperation outside the game and the training. Lastly, we discuss the maining of this theory respect to the sportive team's dynamics, and its relevance for the applied psychology, both for the evaluation and the interventions on the teams.
