Why standardized factor loading > 1 ? (CFA in lavaan)

Question

I am runing CFA in R with the lavaan package. My model is one factor with 5 variales.

I set std.lv = TRUE, but the estimated factor loading is still > 1. Can I report the std.all column as my standardized factor loading?

Thank you.

Here are my code and results:

fit <- cfa(APV.model,data = data_sun,std.lv = TRUE)
summary(fit, standardized=TRUE)

lavaan 0.6-10 ended normally after 20 iterations

Answer 1

I set std.lv = TRUE, but the estimated factor loading is still > 1

std.lv = TRUE only standardizes the latent variable (lv). That's why the unstandardized loadings match the partially standardized solution (std.lv) in your summary() output.

Can I report the std.all column as my standardized factor loading?

Yes, that is the fully standardized solution, which expresses the loadings/slopes in units of SD for both the predictor (common factor) and outcome (indicator).
