Significantly less likely than men who don't attend such training..........
So does that mean the targeting is correct and the people sent on such training are disproportionately those who most need it?
If you want a test of how effective that training is you could try an AB test. Study a large group of attendees, half before and half after such training. Or a large group of men a few months before and after such training to see if those who attend make more progress than those who don't. Comparing those who don't attend with those who do would only make sense if the attendees were randomly chosen.
