Standardized Difference for binary variables

1. Standardized Difference for binary variables

Hello friends

I was recently addressed by a question regarding measuring the effect size between two binary groups using Standardized Difference.

There is a paper ("A unified approach to measuring the effect size between two groups using SAS ® Dongsheng", Yang and Jarrod E. Dalton, 2012) addressing this issue and mitigating it using a SAS Macro: https://www.lerner.ccf.org/quantitative-health/documents/stddiff.sas

I could not find any equivalent procedure using SPSS. Does anyone here have some experience with calculating effect size between two binary groups using Standardized Difference using SPSS?

Thanks!
