education lesson to promote farmers' market fruit and vegetable purchases and consumption
among women enrolled in the Special Supplemental Nutrition Program for Women, Infants and
Children (WIC).
This study is evaluating the WIC Fresh Start program, a theory-driven, web-based nutrition
education lesson to promote fruit and vegetable (FV) consumption among women enrolled in the
Special Supplemental Nutrition Program for Women, Infants and Children (WIC). Designed to
leverage vouchers provided to WIC participants for FV purchases through the Farmers' Market
Nutrition Program (FMNP) and monthly cash value vouchers (CVVs) redeemable at farmers'
markets, the lesson is conceptually grounded in formative research on knowledge, attitudes
and skills influencing farmers' market FV purchases and consumption and theoretical
understanding of approaches for modifying them. Lesson content delivery is primarily through
short video segments and audio output to increase accessibility for low-literate learners.
Informed by a community-based participatory research approach, WIC participants are engaged
as full partners in the development of the lesson and the delivery of content (videos
feature WIC participants). The setting is a large WIC agency serving three New Jersey
counties. Separate samples of women were recruited to participate in 1) focus groups for
guiding lesson content development (N = 56 participants) and pretesting the resulting
content (N = 52 participants), 2) cognitive testing to assess the clarity and
interpretability of items and response formats in measures of knowledge, attitudes and
skills developed for the study (N = 15), 3) one-on-one sessions to assess reactions to
initial versions of video segments developed for the lesson (N = 20), and 4) the outcome
evaluation (N = 744). Stratified based on FMNP voucher receipt, participants are randomized
to receive the lesson or existing online health education. Outcome measures (administered
orally to reduce literacy demands of the response task) are completed at pretest
(immediately before the lesson), posttest (two weeks after the lesson), and 3 and 6 months
after posttesting. Short- and long-term lesson effects on FV intake, FMNP voucher redemption
and redemption of CVVs at farmers' markets will be evaluated. Evidence for mediation by
knowledge, attitudes and skills of lesson effects on FV intake and voucher redemption,
dose-response relationships, and user satisfaction with the lesson also will be examined.
