CONSUMER-BASED COMPUTERIZED FOOD FREQUENCY QUESTIONNAIRE

这项研究的目的是开发和评估消费者- 管理的计算机化食物频率调查问卷(CFFQ) 消费者。CFFQ将设计为便于数据输入 消费者。数据输入将需要最少的时间，并提供 可理解的输出与实际应用，供消费者使用。 CFFQ将以《膳食筛查和评估表》为基础 由国家癌症研究所开发，将适应 用户友好的Macintosh环境。形成性评价将是 在纽约西部的一家家庭实践专业公司进行 约克市。信度和效度将通过比较 对饮食召回进行了为期3天的营养分析 开发了CFFQ。CFFQ适合门诊使用， 候机室设置，大学和中学教室，以及健康 推广和健康计划。该软件程序将提供一个 用最小摄入量快速评估正常膳食摄入量 消费者可理解的应诉负担和产出。目前 没有针对食物频率的软件程序供 消费者。其他计算机化的食物频率问卷需要 时间密集的采访和专业的数据输入。在第二阶段， CFFQ将在患者健康计划中进行实验评估 为了确定食物频率问卷的使用是否有所改善 食物选择。

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.
