Dear krishswethu
Validated measurement tools can rarely be accessed at no cost. However, I recently undertook some research for a govt department which looked at using a measurement and intervention strategy called "ASSET".
You will find more information at this website :
http://www.robertsoncooper.com/ and in particular on the page

I have also attached a presentation by Robertson Cooper for information. The presentation is geared toward law and order agencies, but the ASSET approach applies to any work context.
All the best.
