Conclusions
In this cluster randomized trial, GP training on managing common child mental health problems did not demonstrate greater improvement in child SDQ scores. However, the findings suggest that adding a child component to adult collaborative care may improve service access, but not all generalists may benefit equally from child training. As mental health training for generalists spreads, identifying clinician characteristics associated with patient outcomes and tailoring training to clinicians’ capabilities may help make the most efficient use of scarce training resources.
