Validating instruments of measure : Is it really necessary?
In this April issue of the Malaysian Family Physician, there are two manuscripts on the validation of instruments. The first manuscript is the validation of the Malay version of the Berlin Questionnaire to identify Malaysian patients at risk for obstructive sleep apnea,1 whilst the second manuscript is on the validation of the Malay version of the Diabetes Quality of Life for Youth Questionnaire.2
All instruments assessing patient reported outcomes have to be evaluated for its reliability and validity in the country prior to its use. The purpose of this is to ensure that the instrument used is measuring what it is supposed to measure. This is applicable to instruments that have been developed in English by other authors, and validated elsewhere; as well as self-developed instruments or those that have been modified (e.g. translated into another language or otherwise).
