Limitations and Strengths
This study has limitations. It was not powered to examine all the complexities of collaborative care.We caution, too, that our study took place within an existing collaborative and might not generalize to GPs overall or to other collaboratives. Brief trainings might not benefit generalists not already comfortable with adult mental health. Additionally, the results might not translate to clinicians who care only for children, since the GPs’ attention to parents might have played a role in children’s improvement. Conversely, had screening been a routine clinical practice within the collaborative, detection rates and child outcomes might have been better.Strengths include enrolling a relatively large number of clinicians of a type commonly providing primary care in countries across the income spectrum
