Can you write a few words about the purpose of your research?

The organizational literature on these concepts phrased positively is very extensive. If you do a review of "trust" and "organizational justice" you'll find lots of information.

Hello Dr. Kahn:

The most widely used measure of “interpersonal justice” appears in a four-dimensional scale that was constructed and validated by Colquitt (2001). (Apart from interpersonal, the other three justice dimensions are distributive, procedural, and informational.) The measure is in the public domain and you are able to use it without charge.

 If you would like to assess interpersonal “injustice” separately from interpersonal “justice,” then I would recommend a later paper by Colquitt and his colleagues (2015). These and other relevant articles are listed below.

 Best of luck with your work,

 Russell Cropanzano

Thanks for the value able comments Prof. Dr Russell Cropanzano i have studied Colquitt later work recommended by you but it also asses the same interpersonal justice. Can you please guide me if i can reverse code "interpersonal justice" in order to measure "interpersonal injustice".
