This whole subject is challenging, believe I know! :) The correlation is between diagnosis of ADHD and outcome parameter. IOW among adults with ADHD divorce rate is much higher, IIRC around 2 times the non-affected population rate. The "causal" pathway is obviously complex, but bear in mind ADHD has a broad impact on functional domains, so an individual afflicted with ADHD will fail relationally, in education, employment, health and so on, one adversity compounding others. For example, a married man loses his job because he can't get paperwork done, or keep schedules organized, which puts a strain on marriage due to financial stresses, eventually producing enough discord that the wife bails on the marriage. The research on functional deficits has been going on a long time, and is well-vetted in peer reviewed journals. The confounds have been accounted for.
