The Validity and Reliability Construct Skills Assessments Skill in Korfball by Using Exploratory Factor Analysis and Confirmatory Factor Analysis

This research aims to know the quality of instrument proved through the construct validity and construct reliability of korfball-playing skill assessment. This research and development applied the modified development model of Strand & Wilson. The performance control sheets were used as the main instrument to observe the korfball-playing skills. The data were analyzed using the Exploratory Factor Analysis (EFA) technique, which is prolonged by the Confirmatory Factor Analysis (CFA) technique to make a good instrument for performing korfball-playing skills observation. The EFA analysis uses software support of SPSS 23.0 and CFA analysis uses software LISREL 8.8. This research is obtained that the estimation of construct of reliability is reliable, where the result of estimation of reliability use confirmatory factor analysis in the indicator of skill execution as well as decision making which are about 0.80 to 0.88. This research is also obtained of construct of validity is valid, where the result of estimation of validity use confirmatory factor analysis in the indicator of skill execution which are about 0.87 to 0,95. Estimation of validity in the indicator of decision making is about 0.73 to 0.79. The result of this research shows that the instrument which used to measure korfball-playing skill is considered valid, reliable, and meets the criteria of a good instrument which shows that the developed assessment model is fit to the actual data.
