Method: One hundred sixty-eight youths, aged 6 –15 years, 59.5% male, 85.1% Caucasian, were treated for anxiety, depression, traumatic stress, or conduct problems by clinicians employed in community mental health clinics. In Phase 1 (2.7 years), 1 group of clinicians, the Sustain group, received training in Child STEPs (a modular transdiagnostic treatment + weekly feedback on youth response) and treated clinic-referred youths, guided by weekly supervision from external STEPs experts. In Phase 2 (2.9 years), Sustain clinicians treated additional youths but with supervision by clinic staff who had been trained to supervise STEPs. Also in Phase 2, a new group, External Supervision clinicians, received training and John R. Weisz, Department of Psychology, Harvard University; Ana M.
