Sensitivity analysis using earlier time points (SDQ peer problems at 9.5 years; SMFQ at 13 years) to check timing of mediators. The article reports mediation of "over 20% of the total relationship".

"We found that peer problems at age 9.5 years (prior to the typical age of onset of depression) still mediated the association between ADHD symptoms at age 7.5 years and depressive symptoms at age 13 years, accounting for over 20% of the total relationship (Supplement 2)."
