Hi,
I am also looking for the same questionnaire, Whats your topic in pay sat? I am also doing academic research in the same area. My project is also on pay satisfaction, actually I am finding the reasons for dissatisfaction with pay, among Indian employees. There is a new questionnaire the comprehensive compensation satisfaction questionnaire (ccsq) it is on similar lines but has more dimensions than psq. Do check that it's easily available, validated and the authors are encouraging researchers to use it.
Thanks
