The present study analyzed the relationship between the level of self-efficacy of the player with the ball in basketball, various performance indicators, and individual participation of the youth player in competition, with the goal of being able to establish initial values that help to define game styles and systems that are adapted to the characteristics of the youth player. In order to evaluate the levels of self-efficacy, a questionnaire was administered to 187 players from the under-16 age category. From a total of 22 games, the following variables related to the individual performance of the player were analyzed: a) points scored; b) shot attempts and shots made of 1, 2, and 3 points; c) efficacy percentage of 1, 2, and 3-point shots; d) rebounds made; and e) personal fouls received. With regard to participation, the following variables were analyzed: f) minutes played; g) total time of ball possession; h) number of ball possessions; i) number of passes received; and j) number of offensive phases in which the player participates. The results indicate that the performance and participation variables correctly classify 74.2% when differentiating between players with high and low levels of self-efficacy. The players with high levels of self-efficacy presented higher values in the different performance and participation variables than the players with low levels of self-efficacy
