The impact of measurement goals on the design specification for outcome measures.
No outcome measure has universal validity and applicability. When designing, promulgating or selecting a particular instrument, audiologists should take care to consider and specify the detailed purposes to which the measure will be directed, and the particular populations to which it will be applied. Scales that have been optimized in one arena will have limited (though perhaps still useful) generalizability. The importance dimensions of difference between applications are numerous.
