The purpose of this study is to develop and evaluate a consumer- administered, Computerized Food Frequency Questionnaire (CFFQ) for consumers. The CFFQ will be designed for easy data entry by the consumer. Data entry will require a minimum of time and provide a comprehensible output with practical application for use by consumers. The CFFQ will be based upon the "Dietary Screener and Assessment Form" developed at the National Cancer Institute which will be adapted to the user friendly Macintosh environment. Formative evaluation will be conducted at a family practice professional corporation in Western New York. Reliability and validity will be determined by comparing an interviewed assisted 3-day nutrient analysis of dietary recalls with the developed CFFQ. The CFFQ will be appropriate for use in outpatient, waiting room settings, university and secondary classrooms, and health promotion and wellness programs. The software program will provide a rapid method of assessment of usual dietary intake with minimal respondent burden and output comprehensible to the consumer. Currently there are no food frequency software programs directed for use by the consumer. Other computerized food frequency questionnaires require a time-intensive interview and professional data input. During Phase II, the CFFQ will be experimentally evaluated in a patient wellness program to determine if the use of the food frequency questionnaire improved food choices.

本研究的目的是开发和评估消费者- 计算机化食物频率问卷（CFFQ） 消费者CFFQ将被设计为便于数据输入， 消费者的数据输入将需要最少的时间，并提供 可理解的输出，具有实际应用，供消费者使用。 CFFQ将基于“膳食筛选和评估表” 在国家癌症研究所开发的，将适用于 用户友好的Macintosh环境。形成性评价将是 在新西部的一家家庭实践专业公司进行 约克。将通过比较一个 访谈辅助3天营养分析的饮食回忆与 开发CFFQ。CFFQ将适用于门诊患者， 候诊室环境、大学和中学教室以及卫生 推广和健康计划。该软件程序将提供一个 最低膳食摄入量快速评估法 被调查者的负担和消费者可以理解的产出。目前 没有食物频率软件程序直接用于 消费者的其他计算机化的食物频率问卷需要一个 时间密集的访谈和专业数据输入。在第二阶段， CFFQ将在病人健康计划中进行实验性评估 以确定食物频率问卷的使用是否改善了 食物选择
