I conducted interviews with 30 people on their perceptions towards Device X. Based on previous literature, the perceptions woud be categorised under 3 factors: Factor A, factor B and Factor C.

I've transcribed all the interviews data and roughly I found some additional factors, namely Factor D and Factor E.

My question is, how do I analysed these and confirm on these factors? I know I could use confirmatory Factor analysis (CFA), but I don;t know how I could do it. The materials I found over the internet mostly explain on the statistical formula. I wanted to know how CFA works (not in statistical explanation).

I would really appreciate any reply..

Thanks a lot!!
