Psychometric Validation of the Tactical Assessment Instrument in Football for Use in Physical Education and with Youth Sport Teams.

Recently, the Tactical Assessment Instrument in Football (TAIS) was developed to address football's tactical requirements in terms of game phases, learners' roles, and organizational levels of play. In this study, we sought to evaluate the psychometric properties of this existing instrument in the Physical Education (PE) context and for youth sport teams (ages 812 years). Our research design involved: (a) participants playing 37 football games, (b) assessing participants via observation with the TAIS and (c) conducting psychometric analysis on the obtained assessment data.

Design and Validation of the Tactical Assessment Instrument in Football (TAIS).

The focus on tactics has made assessment more difficult due to the lack of knowledge in the topic and the limitations of current tactical assessment instruments. : To design and validate a tactical assessment instrument in youth football (TAIS) following an exhaustive, ecological and meticulous process and dealing with the limitations found in the literature. : The design was divided in two stages related to its development and validation.

A Teaching Games for Understanding Program to Deal With Reasons for Dropout in Under-11 Football.
