Construction of self-efficacy scale: A psychometric study for students

The purpose of this study was to analyze the construct validity and the construct reliability of self-efficacy, and to find indicators that form the construct of self-efficacy. Self-efficacy was measured by three aspects, namely level, generality, and strength. The subjects of this study were 68 students of SMP X. Data collection method in this research was using self-efficacy scale. The data of this research were analyzed by using Structural Equation Modeling (SEM) SmartPLS 3.2.8 with reflective constructs through CFA 2nd Order. Based on the results of the analysis, the aspects and indicators that form self-efficacy were declared valid and reliable. The most dominant aspect in reflecting the construct of self-efficacy was the level with a loading factor value of 0.905. The lowest aspect that reflects the construct of self-efficacy was generality with a loading factor value of 0.602. This result shows that all aspects and indicators were able to reflect and form self-efficacy variables. Therefore, the structural model could be accepted because the theory which describes self-efficacy was in accordance with empirical data that are obtained from the subjects
