The aim of the study was to adaptive and validate of the Spanish version (Sánchez & Núñez, 2007) the Basic Psychological Needs Scale in Exercise (BPNES: Vlachopoulos & Michailidou, 2006) into football. Thus, 430 football male players ranging in age from 11 to 18 years old, from infantile (n = 185), cadet (n = 166) and juvenile (n = 79) categories participated in the study. A confirmatory factorial analysis with adequate adjusted indexes was conducted, in which the three basic psychological needs associated with scores of between .59 and .87. Moreover, an internal consistency analysis (Cronbach´s alpha) with acceptable results over .70 was developed. Following, with the aim to test the concurrent validity of the scale, factors of the Motivation in the Sport Questionnaire (Pulido et al., 2015) were correlated, emphasizing high and positive relationships between the three BPN and the most self-determined regulation (.17 and .26). Finally, a scale with adequate psychometric properties with the purpose to examine BPN satisfactions of football players was showed.
