The purpose of this research is to evaluate the validity and reliability of the Quantitative Workload Inventory (QWI) developed by Paul Spector and Steve M. Jex (1998). In this methodological study, the sample is composed of 101 Social Workers who work in various public institutions and organizations in Bursa and agree to participate in the research. There are 5 items in the Quantitative Work Load Inventory. The data were collected with “ demographic questions” and “Quantitative Workload Inventory” consisting of 5 items. In the analysis of the data, explanatory and confirmatory Factor analysis (Kendal W Analysis) for the content validity with the help of Structural Equation Model, Cronbach alpha coefficient for the internal consistency of the scale in the reliability study and Pearson Correlation Analysis for item total score analysis were used. According to the findings obtained, it was determined that there was an agreement between expert opinions on the items in the scale. The Cronbach alpha coefficient of the scale was .93 and it was determined to have a high degree of reliability. As a result, Quantitative Workload Inventory developed by Paul Spector and Steve M. Jex (1998) and original English language has a high level of validity and reliability for our country. It is suggested that the scale should be used in the Turkish society to evaluate the workload of employees belonging to various professional groups involved in working life.
