Cross-cultural adaptation of Oral health related Quality of life measures
Questionnaire has been widely used in all areas of specialties especially in measuring subjective phenomena. A questionnaire is an instrument consisting of a series of questions and other prompts for the purpose of gathering information from respondents (Wikipedia). In order to gather useful information from the respondents about the phenomena of interest, questionnaire needs to be properly constructed. One such phenomenon is Oral health related Quality of life (OHRQoL), which is one of an important outcome in oral health care. Questionnaires for assessing OHRQoL usually contain multiple questions. The development of OHRQoL questionnaire will depend on whether we want to develop a new OHRQoL questionnaire or we want to adapt existing OHRQoL questionnaire, which has been developed in other countries. Since there are number of OHRQoL measures available and to facilitate cross culture comparison, it is recommended that we adapt the most commonly used measure. However, the adaptation must be done thoroughly to ensure validity and reliability of the measure adapted. This presentation will discuss on the processes and issues related to adapting an existing OHRQoL measure.
