PSM (ATET and ATE)

[Adeola Kolade]

Hi all,

I will really appreciate your help on this. I estimated my analysis using the PSM method in stata. I calculated both the Average Treatment Effect (ATE) and the Average Treatment Effect on the Treated (ATET) and find opposing results.
ATET- shows a positive and significant result for the effect of childhood obesity on adult depression
ATE- however shows a negative and insignificant result for the effect of

childhood obesity on adult depression. Please could someone help on interpreting this as results are different?
Many thanks.
