I am trying to do something quite similar: Identifying a mental health scale similar to the anxiety categories you generated here. The problem is that however I have categorical variables and not dummy variables. Should I convert those variables to dummies before doing the EFA?
You need ordinal or binary variables to be able to run EFA. Having a larger number of categories is preferable. If you tell me more about the nature of your variables I could give you more specific suggestions.
Diana Mindrila I currently have a set of variables from survey that asked respondents about multiple aspects of their mental health. These were usually ordinal with responses such as "often - never" or "Strongly agree - strongly disagree." What I want to do is to reduce those numerous variables using EFA. Do I need to convert those variables into dummies in order to do the EFA like you did? I am running stata if that is of any relevance to your answer. Thank you so much for the video and for replying.

Explanation is very concise, so helpful to grasp the concept of EFA. Thank you so much. Do you have something on canonical analysis
Thank you, no I do not have anything on canonical analysis yet
It was really helpful thank you.
