I have translated the Ryff Psychological Well-being scale into Vietnamese and collected 800 responses from university students. The main construct is psychological well-being, which is comprised of 6 distinct dimensions. I used the 54-item scale with 9 items per scale (9 times 6 = 54).
The items appear to be formative and not reflective thus I am told that an EFA is not appropriate for formative items.
I want/expect to confirm that the Vietnamese version also shows the 6 dimensions found by previous research. So how should I proceed? I have not found a clear standardized approach to handle this question. The videos and writings I have read do not seem to agree on the appropriate method to take.
Anyone who has done this kind of work I would love to hear from you. Thanks.
