Summary
A new tactical assessment instrument in youth football (TAIS) was developed and validated for 8-12-year-olds. This tool reliably assesses tactical outcomes, addressing limitations in current youth football assessment methods.
Area of Science:
- Sports Science
- Pedagogy
- Motor Control
Background:
- Current tactical assessment in youth football is hindered by a lack of topic knowledge and inadequate instruments.
- Existing assessment tools face limitations in ecological validity and comprehensiveness.
Purpose of the Study:
- To design and validate the Tactical Assessment Instrument in Youth Football (TAIS).
- To overcome limitations in existing tactical assessment literature through an exhaustive, ecological, and meticulous process.
Main Methods:
- Instrument development involved literature review, exploratory observation, and expert consultation.
- Validation included content, comprehension, construct, and criterion validity, alongside inter-rater reliability testing.
- Systematic game observation and comparison with the Game Performance Assessment Instrument were employed.
Main Results:
- The TAIS is a valid and reliable tool for assessing tactical outcomes in 8-12-year-old youth football players.
- The instrument comprises 22 criteria, effectively measuring tactical performance.
Conclusions:
- The TAIS offers practical advantages, assessing multiple tactical levels and player roles.
- It provides results without general indexes, accommodates diverse institutional contexts, and includes contextual variables.
