I am conducting a research which involves scale development for emotional experiences with Wanghong (Internet-famous) restaurant dining consumption. With reference to the steps in prior literature, I have already done interview and expert review on the measurement scales. It is interesting to see that the emotional experiences may be categorized into three stages, pre-, during, and post-dining experience. I have conducted the first study, with the objective to purify the scale. I have done one analysis on all the measurement items using EFA without the consideration of three stages, and four factors emerged. In order to reflect the finding that emotional experiences are different in the three stages, I think three EFAs should be conducted? It seems to me that the first way is more methodological correct, while the second way is more theoretically or conceptually correct. Would appreciate if anyone may give me some advices on this! Thanks a lot!
If you believe the the pre, during, and post have different influences, you might consider CFA rather than EFA.
Thanks @Daniel Wright! Do even if my items are newly developed from interviews, I could go straight to CFA?
Yes , I do .
With our appreciation to your scientific efforts doctor ,
I'd definitely recommend three because different considerations may apply at each stage, e.g., primarily reputation at Stage 1, dining and service experience at Stage 2, and the bill at Stage 3.
