What if my standardized loading factor is less than 0,5 but greater than 0,3?

After I conduct a validity test on my Lisrel, the result comes out. Some of my indicators showed 0.4 score on the standardized loading factor score. I heard that there are some experts that still...

Is 0,4 score in component matrix still considered to be acceptable on pretesting?

I was running on my research and suddenly I found that one of my indicator have a low component matrix score, 0,445. This is still a pretesting phase and I used 35 samples for running the data. Is...
