A Construction of Agility Test for The University Korfball Athlete

Abstract

This study aimed to evaluate the quality of an agility test and establish normative standards for university korfball athletes. Content validity was assessed by seven experts using the Index of Item–Objective Congruence (IOC). Concurrent validity was determined by examining the correlation between the developed test and the Illinois Agility Test. Reliability was assessed using a test–retest method with a one-week interval, while objectivity was determined by examining the correlation between scores recorded by two testers. The population used to establish the normative standards consisted of 180 university korfball athletes, including 99 male and 81 female athletes. Data were analyzed using the mean, standard deviation, Pearson’s product–moment correlation coefficient, and T-scores.

          The results showed that the developed agility test for university korfball athletes demonstrated acceptable content validity, with IOC values ranging from 0.71 to 1.00. The concurrent validity coefficient was 0.91, indicating a very good level; the test–retest reliability coefficient was 0.82, indicating a good level; and the objectivity coefficient was 0.94, indicating a very good level. Normative standards were established separately for male and female university korfball athletes and classified into five levels: very good, good, moderate, low, and very low. These findings indicate that the developed test demonstrates satisfactory validity, reliability, and objectivity and can be used to assess agility among university korfball athletes.
