Dear,

Is there a general rule of how many participants are needed in a file with 10 variables (8 scales, age and sex) to conduct latent class analysis on?

Thank your very much!!!

No, there is no set rule for this. You would need to do a Monte Carlo study to determine this. See the following paper which is available on the website:

Muthén, L.K. & Muthén, B.O. (2002). How to use a Monte Carlo study to decide on sample size and determine power. Structural Equation Modeling, 4, 599-620.
