Hi, just to say that I really like the idea of the post-hoc test here. I don't know if it's the exact same implementation currently available in SPSS, but the one I've used in R is based on this:

Beasley, T. M., & Schumacker, R. E. (1995). Multiple Regression Approach to Analyzing Contingency Tables: Post Hoc and Planned Comparison Procedures. The Journal of Experimental Education, 64(1), 79–93. https://doi.org/10.1080/00220973.1995.9943797

in the chisq.posthoc.test package

Best,

Tarandeep
