I'm starting to analyse data for my dissertation.

My study has 3 variables- filter use, body image satisfaction, and consideration of cosmetic surgery.

my hypothesis was participants who use filters will have lower body image satisfaction and will be more likely to consider cosmetic surgery.

So, my IV= filter use and the other 2 are DVs.

I've been told to do a pearsons r correlation and a regression analysis, however I dont know if I can do these with all 3 variables together, or if I need to do seperate analyses for 1. filter use and body image satisfaction, and 2. filter use and consideration of cosmetic surgery.

Any help would be greatly appreciated!!
