Results: The initial 41-question survey was condensedto 29 questions based on statistical analysis, the repet-itiveness of content, and expert opinions. A few re-sponse items were deleted because of being rated‘‘too easy’’ or ‘‘too hard’’ by content experts. TheKuder-Richardson 20 score for the final survey was r¼ 0.553.Conclusions and Implications: This knowledge surveywill provide a valid and reliable instrument for measuringfood safety knowledge among the main food preparers inHispanic families with young children. More emphasiswas placed on expert opinions and simplicity of the surveythan statistics because of the small sample size of a homog-enous population.Funding: USDA Project: Food Safety for Diverse Familieswith Children 25-6236-0079-001.

P71 Attracting the Next Generation of FoodSafety Professionals through Marketing andEducation in High SchoolsJ. Garden-Robinson, PhD, RD, LRD, julie.garden-robinson@ndsu.edu, North Dakota State University, EML 351,Department 7270, Box 6050, Fargo, ND 58108-6050;K. Beauchamp, MS

Objective: This study analyzed student interest in foodsafety–related degrees and careers after exposure tomarket-ing and educational interventions.Design, Setting and Participants: After expert reviewand approval by the university's Institutional ReviewBoard, pre- and postsurveys were administered to highschool students (grades 9 to 12) enrolled in food-relatedclasses in 7 high schools (n ¼ 138; 51% girls). Partici-pants were assigned to one of 3 treatment groups. Treat-ment interventions (video, brochure, hands-on game)were introduced to students immediately upon comple-tion of the presurvey. A follow-up survey was conducted3 weeks later.OutcomeMeasures andAnalysis: Frequency data wereanalyzed with the SPSS computer program.Results: Participants (18%) agreed with the statement‘‘plan to enroll in a food safety program’’ (up 2% fromsurvey 1). However, 79% of the participants did notknow whether the college they may attend offersa food safety program. The percentage of individualswho had decided on a major increased to 39% after anintervention (up 7%). The number of undecided individ-uals was greatest at the freshman level (38%). The per-centage of individuals who had decided on a major wasgreatest among those in the video group (52%) com-pared with those in the brochure (27%) or game (21%)groups. Participants (54%) ranked annual income asthe most influential factor in selecting a major. Moregirls (16%) than boys (10%) currently are working infood-related jobs.

Conclusions and Implications: To address the US na-tional need for food-safety experts, a variety of educationalinterventions should be used to target high school stu-dents as early as freshman year.Funding: Higher Education Grant Challenge project,USDA.

P72 Validation of a Native American FoodSafety Knowledge SurveyM. Siebert, MS, cperry2@unm.edu, University of NewMexico, 714 Cromwell SE, Albuquerque, NM 87102;C. Perry, PhD; J.

Objective: To validate a food safety knowledge survey cul-turally appropriate for Native American populations.Design, Setting and Participants: Quantitative andqualitative methodologies were used to establish contentvalidity, cultural appropriateness, and internal consis-tency of a food safety knowledge scale. A panel of 6experts participated in the content validity study. Toestablish psychometric properties, 30 Native Americanprimary food handlers in a home with children youngerthan 10 years completed the Food Safety Knowledgesurvey. Detailed interviews were conducted with 6 keyinformants about language, features, and cultural appro-priateness.Outcome Measures and Analysis: Experts rated mea-surement items across 4 validity factors: content do-main match, construct relevance, representativeness,and clarity. A 4-point Likert scale with varied anchorswas used. Three types of analyses were conducted todetermine degree of content validity: interrater agree-ment, content validity ratios, and factorial validity in-dex. Further analyses were conducted to determineitem difficulty, item discrimination, and internal con-sistency. Key informant interviews were analyzed foritem difficulty, format, wording, and cultural appropri-ateness.Results: Interrater agreement values and content validityratios indicated strong representativeness and clarity. Theaverage factorial value indicated that experts assigned scaleitems to their appropriate domain. The Kuder-RichardsonFormula 20 yielded an internal consistency of 0.793. Keyinformant interviews were used to enhance cultural appro-priateness.Conclusions and Implications: A quantitative ap-proach to content validity provides a comprehensive eval-uation and clear focus for revision of scale items.Subsequent analyses, internal consistency, and key infor-mant methods provide additional psychometric propertiesand information about cultural appropriateness. This pro-cess can guide public health educators to critically reviewmeasures used in their work.Funding: USDA 2010-51110-21143.
