The present study is about the application of JAWS (Job Affected Well-being Scale) that has been designed by Katwyk, Fox, Spector, Kelloway (2000) for measuring the different affects that have an effect on people’s perceptions on their subjective job-related well-being. The first part of the paper will present the findings of the reliability analyses of the Turkish version of the scale. The second part will include the results of the analyses of participants’ total JAWS scores by the AnswerTree. The findings of the present study showed that the most effective predictors of participants’ subjective job-related well-being were age, and years of work. The findings will be discussed in relation to the applicability of the scale in studies on industrial/organizational psychology.
