A three-pronged approach to evaluation developed previously for the program was used to measure outcomes, process, and fidelity of the program. The control group, youth (n=63) and adults (n=71), and treatment group youth (n=76) and adults (n=75) completed pre- and post-program surveys. Treatment dyads completed the intervention, eight bi-weekly sessions on program focal areas of cooking, eating, and playing together. Treatment youth significantly increased outcome subscales of cooking skills (P
