The goal of this evaluation was to understand the planning, implementation, and execution of the Put Families First program as it is administered by Functional Family Therapy (FFT) in the District of Columbia (D.C.). The primary question is whether FFT has been implemented with high fidelity and quality, and whether there are local factors or circumstances that either facilitate or interfere with its reliable implementation. The current implementation evaluation shows promise for the effective implementation of FFT for youth at risk of out-of-home placement in D.C. For those who do complete the program, implementation is generally close to program benchmarks and showing improvement.
