Uses of process evaluation in the Maryland WIC 5-a-day promotion program.
Using a crossover design, the authors conducted a 6-month intervention program aimed at increasing fruit and vegetable consumption among women served by the Women, Infants, and Children program in Baltimore City and six Maryland counties. The theoretical framework for the interventions was the Transtheoretical Model of Change. At 2 months postintervention, mean daily consumption had increased significantly more in intervention participants than in control participants. Extensive process evaluation data were collected to assess the quantity and quality of program services delivered. These included participant nutrition session evaluation forms and attendance logs, focus groups of attenders and nonattenders of sessions, information about peer educators, and postintervention surveys. Many lessons were learned about program delivery, factors affecting attendance, and the obstacles to dietary change. Strategies to increase participants' consumption of fruits and vegetables were modified based on these lessons and the process evaluations.
