Qualitative By Dave Collingridge I remember years ago walking the halls of the faculty offices at my university asking for help on validating a questionnaire.

I repeatedly asked professors, “Can you tell me how to validate the questions in my survey?

It is rare, if nearly impossible, that an instrument be 100% valid, so validity is generally measured in degrees.

As a process, validation involves collecting and analyzing data to assess the accuracy of an instrument.

) the quality of the data is unclear because registry birthplace information is incomplete. Cultural validity for all instruments is essential principle but unfortunately one that is seldom achieved.

In the case of assessment, for example, “In the case of non-English-speaking or multilingual participants, investigators should use translated versions of standardized instruments that have been subjected to rigorous standards of measurement equivalence to ensure that the desired psychological constructs are properly measured” (Fisher, Hoagwood, Boyce, Duster, Frank, Grisso, Levine, Macklin, Spencer, Takanishi, Trimble, & Zayas 2002; Fisher & Wallace 2000).
