Assistant Prof. Hatice EK?NC?

Abstract
This study aims at developing a self-efficacy scale for individual performance. After reviewing the literature in this field, experts’ opinions have been considered and a test data pool consisting of 17 items has been formed. This scale has been read by thirty four students and its comprehensibleness has been checked. The scale was organized in the form of 5 point likert scale with the expressions of “Never”, “Rarely”, “Not sure”, “Sometimes”, “Always”. This test form for the measurement of individual performance has been applied to 230 music teacher candidates at the age of 18-22 and above and who have taken an instrument course for at least 1 year. In order to obtain proofs for the validity of the scale, first basic components analysis and then explanatory factor analysis have been performed. As a result of the explanatory factor analysis, 3 items have been removed from 17 items and the total number of items has become 14. As a result of the reliability analysis of the whole scale, reliability co efficiency has been found to be ,88. In conclusion, it has been detected that the self-efficacy scale is a valid and reliable instrument in measuring the self-efficacy of the music teaching students at the age of 18-22 and above in their individual performances.
