Organizational researchers are interested in the measurement of psychological variables which affect the productivity of organizations. There are many methods available to assess psychological variables using the principles of psychometrics. Work stress is an important psychological variable which is largely studied by different researchers. While searching an instrument to measure stress of an employee working in different organizations, the absence of suitable instrument with limited number of items were noticed. By adopting method suggested by Edwards (1957), Seema (n.d) and factor analysis, a scale with 21 item one-dimensional “work stress scale (G)” was developed. The reliability of the scale was established by finding out the Cronbach Alpha and distributing the items among subject experts the face validity also established. The sum total of the items constitutes the work stress of an employee.
