Reference category: risk of moderate/serious mental illness (Kessler Psychological Distress Scale score 8 or above n=4142) v. n=11 820 in the full model due to missing data. Demographic and risk exposure variables were simultaneously entered. Support variables are partially adjusted by demographic and risk exposure variables. Visit from relative is not independent of visits listed so is not included.
