Maybe I chose the wrong word. Writing good summaries is hard! What they describe in the paper (they call it a "treatment") is more like a training for newlywed

Maybe I chose the wrong word. Writing good summaries is hard! What they describe in the paper (they call it a "treatment") is more like a training for newlyweds. Maybe I should have phrased it like this: Couples who decline to take part in free relationship training have higher divorce rates. Or, more positively: Couples who participate in free relationship training have lower divorce rates. (But that implies causality, so it is again somewhat misleading)
