Building Confidence in Motor Skill Testing for Youth Handball Players: Validity and Reliability Analysis

The assessment of motor skills in youth handball athletes is a critical yet underexplored area, particularly regarding the use of standardized, sport-specific tests for technical proficiency. This study addresses a significant gap in the field by validating and establishing the reliability of three handball-specific skill tests—Dribbling, Wall Quick Passing, and Shooting Accuracy—in female athletes aged 12–14. The novelty of this research lies in the integration of a structured, expert-driven rubric for performance evaluation, which enhances objectivity and transparency in assessing complex technical skills, moving beyond traditional physical conditioning tests. Logical and construct validity were established through expert panel evaluations and Spearman's rho correlation analyses between expert ratings and rubric scores, confirming that the tests accurately measure the intended technical abilities. Reliability was rigorously tested using test-retest methodology, Cronbach's Alpha, Pearson correlation coefficients, and Intraclass Correlation Coefficients (ICCs), all demonstrating excellent internal consistency and measurement stability (ICCs > 0.93). The results provide coaches with robust, evidence-based tools for monitoring athlete development and identifying talent, supporting individualized feedback and targeted training interventions. By offering a standardized, transparent framework, the rubric-based assessments promote fairness and objectivity in selection and development processes, addressing long-standing concerns about subjectivity in talent identification. This approach also encourages the adoption of evidence-based practices in youth coaching, contributing to the broader educational mission of fostering skill acquisition, motivation, and self-awareness among young athletes. While the study's limitations include a relatively small sample size and testing in controlled rather than in-game conditions, its findings lay the groundwork for future research into comprehensive, game-relevant skill assessments. Overall, the validated tests and innovative rubric methodology represent a significant advancement in youth handball performance diagnostics, with practical implications for coaching, talent identification, and the promotion of equitable opportunities in youth sports.
