Underserved groups eat fewer vegetables and fruits compared to families who are not low-income; thus, a target message of low-income nutrition education programs is to increase vegetable and fruit consumption. Validated instruments for measuring behavioral outcomes are important for determining and documenting the effectiveness of these programs, yet many of the questionnaires used to gather behavioral outcome information in children have not been validated. The specific aims of the study were to: 1) develop a questionnaire measuring behavior changes in vegetable and fruit consumption for low-income 9-11 year olds, 2) assess the questionnaire for content validity via judgment of an expert panel and, 3) assess the questionnaire for face validity via focus groups with 9-11 year olds. A comprehensive review of child nutrition questionnaires was performed using a search on relevant databases (such as MEDLINE, ERIC, and WORLDCAT) as well as electronic sources through relevant journals and other documents. Forty-two questions were chosen based on the target audience, to measure behavior change, and relate to vegetable and fruit consumption. The research team in response to recommendations in the Dietary Guidelines for Americans 2010 also developed twelve questions. A total of 54 questions were assessed. An expert panel (n=95) was recruited through purposive sampling to evaluate the questions for content validity using 3 constructs: 1) students will understand the question, 2) students can answer the question, and 3) the question will assess behavior change. After the results of the expert panel were analyzed with α=0.1, questions that received 75% or greater agreement among the constructs and a power ≥.5 were considered to have content validity and were then assessed for face validity. Seven focus groups (FG) were performed with low-income 9-11 year olds and four major themes were identified. The results are 10 content and face validated questions assessing behavior changes in vegetable and fruit consumption in low-income 9-11 year olds.
