In summary, it is not recommended to conduct a

validation study for a questionnaire which does not have a

clear history of proper questionnaire development

process. If a researcher still intends to conduct a validation

study for that particular questionnaire, then it is necessary

for him/her to set up the appropriate reliability and

validity testing for that questionnaire. Some tips on

identifying which test to be used for validation and

reliability-testing of a questionnaire can be obtained by

referring to Table 3.1, Chapter 3. Nonetheless, it must be

borne in mind that prior to the actual validation study, it is

necessary for a researcher to conduct an initial phase of

assessment by performing a proper translation process and

then evaluating both the face validity and content validity

of its translated version, in order to determine whether or

not the subsequent validation study would be feasible and

worthwhile.
