背景资料。了解影响食物选择的因素可能会提高促进健康饮食模式的战略的有效性。本文描述了在工作井项目中制定与饮食模式相关的心理社会因素测量的过程。Working Good是一项工作场所健康促进干预措施的多中心对照试验，包括旨在促进低脂肪、高纤维饮食的营养干预。制定措施的过程包括几个步骤。首先，我们定义了影响饮食行为的心理社会因素的三个领域：易感因素、促成因素和变化相关因素。然后，我们回顾了大规模的调查结果，编制了项目目录，并开发和完善了65个项目的问卷，用于在工作人群中进行预试。根据频率分布和项目间相关性，项目库减少到24个项目。其余24个项目包括在对652名员工的试点调查中(回复率=80%)。在试点数据分析的基础上，我们删除了一项，并对其他项进行了较小的修改。与饮食摄入量最相关的因素是自我评价的饮食、既往的成功改变以及食用低脂食物的动机。对横断面试点数据的分析为最终调查的分析提供了方向。这些措施和开发过程产生了一种可供其他研究人员使用的工具和过程。
Background. Understanding factors influencing food choices is likely to enhance the effectiveness of strategies to promote healthy eating patterns. This article describes the process used to develop measures of psychosocial factors related to eating patterns in the Working Well project.Methods. Working Well is a multicenter controlled trial of worksite health promotion interventions, including a nutrition intervention aimed at promoting low-fat, high-fiber eating. The process for developing measures included several steps. First, we defined three domains of psychosocial factors influencing dietary behavior: predisposing, enabling, and change-related factors. We then reviewed large-scale survey findings, compiled a catalogue of items, and developed and refined a 65-item questionnaire for pretesting in a working population.Results. Based on frequency distributions and interitem correlations, the item pool was reduced to 24 items. The 24 remaining items were included in a pilot survey of 652 employees (response rate = 80%). On the basis of pilot data analyses, we eliminated one item and made minor modifications to other items. Factors most strongly associated with dietary intake were self-rated diet, past success at change, and motivation to eat low-fat foods.Conclusions. Analyses of the cross-sectional pilot data suggest directions for analyses of the final survey. The measures and the development process yielded an instrument and process that can be useful to other researchers.
