st: Propensity score matching -balancing property

[Nyasha Tirivayi <ntirivayi@gmail.com>]

Hello

I have a question concerning psmatch2 and general propensity score matching:

The propensity score model I have used to analyse the first outcome
for my first chapter of research does not satisfy the balancing
property when I apply it to the other outcomes to be presented in
later chapters. Should I use the propensity score model I have used in
the first paper throughout the next chapters for all the outcomes,
even if it does not balance all the time? Or each outcome might
require a separate propensity score model with maybe different
covariates?

Each outcome also has different number of observations. Does this
support the use of separate PSM models?

Kindly respond
