Question: Does an instrument exist already that you can use?

If the answer is NO – ask yourself “Do you have the expertise to create one?”

If you DO NOT have the expertise to create one:

  • Hire/work with someone who does; then write it, test it, review & revise it.
  • Test it again.

If you DO have the expertise to create an instrument, then:

  • Write it, test it, review & revise it.
  • Test it again.

Question: Does an instrument exist already that you can use?

If the answer is YES - does it need to be adapted in some way?

If it DOES NOT have to be adapted: then:

  • Consider any copyright or commercial licensing & cost issues
  • Proceed

If it DOES have to be adapted in some way – identify IN WHAT WAY? E.g., wording; response scales, context, language, format & structure, or length? Then:

  • Consider any copyright or commercial licensing & cost issues.
  • Adapt it, test it, review and revise it.
  • Test it again
