The Development of an Agility Test for Volleyball Players in Demonstration Schools under the Ministry of Higher Education, Science, Research and Innovation

Abstract

There have not been any standardized tests or normative criteria used specifically developed to assess agility unique to the sport of volleyball. This research aims to construct a test, test its validity and construct agility norms for volleyball players of the demonstration schools under the Ministry of Higher Education, Science, Research and Innovation (MHESI). The study was divided into two phases. The first phase was conducted to determine the quality of the research instrument. The content validity was assessed by using the Index of Item Objective Congruence (IOC) evaluated by five experts; concurrent validity was examined by determining the correlation with an agility test; and reliability was assessed through a test–retest method with a one-week interval, administered to 20 volleyball athletes aged 16–18 years who were obtained by purposive sampling; and the objectivity by correlating the scores from 2 testers. The second phase of the study was to create the agility norms for volleyball players of the demonstration schools with a population of 237 volleyball players. The statistics used for data analysis were mean, standard deviation, Pearson's product moment correlation coefficient, and T-score. The findings revealed that the agility test for volleyball athletes in demonstration schools under MHESI had content validity congruence index values (IOC) between 0.8 and 1. It showed a very high level of criterion-related validity (r = 0.89 and 0.82). The test also demonstrated a high level of reliability (r = 0.84 and 0.81) and a very and the objectivity correlation coefficient indicated a very high level of correlation (r= 1). The established normative criteria for the agility test developed by the researchers can be used to evaluate the agility of volleyball athletes.
