There is an instrument was validated outside Malaysia among nurses, then same instrument was translated to malay language and validated inside Malaysia among volunteer participants (not nurses).
I want use this instrument in Malaysia among nurses, Is it necessary to validate again ??
You don't mention how the Malaysian version was validated, but here's what is typically done in published research. The original instrument is translated and then back-translated into the original source language to be sure meaning is maintained. Tests of measurement equivalence/invariance (ME/I) are conducted on samples using the scale in the source language with individuals who are native speakers, and then a sample using the target language. Assuming you have evidence for ME/I, you would proceed to use the scale in samples using the target language. If the prior Malaysian study established ME/I, then I think you could use it with nurses, but be careful that there could be sample differences. One way to check for this is to include some of the scales the prior study did with nonnurses to see if results are similar with nurses. They should be variables where you would not expect differences due to occupation.
In the following, we discuss ME/I and other issues concerning cross-cultural/cross-national research:
Spector, P. E., Liu, C., and Sanchez, J. I. (2015). Methodological and substantive issues in conducting multinational and cross-cultural research. Annual Review of Organizational Psychology and Organizational Behavior, 2, 101-131.
Thank you Paul E. Spector for your answer, much appreciate.
Malaysian version was validated by Content, face and construct validity (EFA, CFA) also reliability was done. Authors mention in his article you may use among may be provisionally used in research and practice in organizational, educational and clinical settings in Malaysia.
In this situation i think no need to validate again.
Any measurement should be valid for the setting and the population where it will be used. If a researcher has used it before with similar people, usually the validity is considered accepted {if it was clearly mentioned in the previous research}. However, reliability should be added from the new study as well.
You might also read the items and check whether they refer to some general human problems or rather problems specific to nurses. If it is a questionnaire that asks about some general aspects not related to any specific occupation, then you have no reason be believe that it will not be valid and reliable for other groups.
If your questionnaire refers to general concepts of nursing (knowledge) then it should be valid to other settings and population but if your questionnaire refers to skills in nursing then I would recommend that you need to validate it because culture in different settings affect nursing skills.
Dear Ali,
Please check the back-translated questionnaire if the items are suited to your nursing respondents.Otherwise the responses might be too general
that the data you will gather will have no significance in terms of adding new information relevant to nursing knowledge.Make the items or questions specific or applicable to nursing then have it validated.
Ali,
The answer, “It Depends” is most accurate. What is your overarching goal? Every study has limitations. As long as you speak to the limitations, it is acceptable to move forward with the tool. If your goal is to validate the tool, then design your study in a manner that provides for a validation arm and a test arm. It is a matter of cost, time and resources when accessing the feasibility of a study. Good luck.

You did not mention the topic of the questionnaire. May be it consisting items that will be different in various settings.if so, you must validate the questionnaire in Malaysia.
No, it is not necessary but you need to compute the Cronbach's alpha again and delete those items that decrease your alpha to less than 0.70. Here you can look at our nurse scale.
