JOB PERFORMANCE, TASK PERFORMANCE, CONTEXTUAL PERFORMANCE: DEVELOPMENT AND VALIDATION OF NEW SCALE

In this study, it is aimed to develop a "Job Performance Scale" in order to measure the job performance of employees with a measurement tool with high validity and reliability based on scientific methods. The study was conducted with data obtained from three different sample groups, including universities, health and industry sectors. As a data collection tool, a draft scale consisting of 12 items prepared by the focus working group in the form of 5-point Likert was used in line with the literature. The data were analyzed with the package program. EFA and CFA were carried out in line with the validity studies. Furthermore criterion validity of the scale is also computed with using the job satisfaction scale. According to the results of the analysis, the "Job Performance Scale" consisted of two sub-dimensions and 11 items. As a result of reliability analyzes, it was determined that the scale was highly reliable. With its two-dimensional structure named task performance and contextual performance, it is evaluated that the scale will fill a gap in the field by meeting an important need for employees to determine and measure job performance in future researches.
