背景：水果和蔬菜（FV）摄入量低是全球和美国慢性疾病的主要危险因素。很多人每天摄入的脂肪量没有达到建议的摄入量。这篇论文描述了美国国家癌症研究所2007年食物态度和行为调查中关于FV摄入的社会心理测量的发展。方法：这是一项对3397名美国成年人进行的横断面研究。量表包括在先前的研究中显示与水果和蔬菜摄入量（FVI）相关的传统构式（例如，自我效能感，社会支持），以及在很少甚至没有研究中测量的新构式（例如，对素食主义的看法，新恐惧症）。FVI用8项筛选法进行评估。进行探索性因子分析、Cronbach’s alpha和回归分析。结果Cronbach’s alpha >= 0.68的社会心理量表为自我效能感、社会支持、进食食物的障碍和益处、素食观、自主和控制动机、对食物的偏好。常规量表(p
BackgroundLow fruit and vegetable (FV) intake is a leading risk factor for chronic disease globally as well as in the United States. Much of the population does not consume the recommended servings of FV daily. This paper describes the development of psychosocial measures of FV intake for inclusion in the U.S. National Cancer Institute's 2007 Food Attitudes and Behaviors Survey.MethodsThis was a cross-sectional study among 3,397 adults from the United States.Scales included conventional constructs shown to be correlated with fruit and vegetable intake (FVI) in prior studies (e.g., self-efficacy, social support), and novel constructs that have been measured in few-to-no studies (e.g., views on vegetarianism, neophobia). FVI was assessed with an eight-item screener. Exploratory factor analysis, Cronbach's alpha, and regression analyses were conducted.ResultsPsychosocial scales with Cronbach's alpha >= 0.68 were self-efficacy, social support, perceived barriers and benefits of eating FVs, views on vegetarianism, autonomous and controlled motivation, and preference for FVs. Conventional scales that were associated (p
