含糖饮料（SSB）消费是一种重要的行为，可以影响个人患糖尿病，肥胖症和其他慢性疾病的风险。然而，缺乏有效的措施来评估SSB相关的结构。可靠和有效的措施可以帮助评估旨在遏制SSB消费的干预措施的有效性。我们的目标是开发一个有效和可靠的工具来衡量结构相关的SSB消费英语和西班牙语。在2016年7月至2017年1月期间，对马萨诸塞州波士顿公共住房开发的150名成年居民进行了方便样本的横断面调查。研究人员通过挨家挨户敲门和张贴传单的方式接触了两个公共房屋发展项目的所有家庭，以征求他们的参与。我们开发的问题来衡量三个SSB相关的结构告知社会认知理论：SSB知识，自我效能感和意图采取行动SSB消费。这些问题在人群中进行了试点测试，然后由双语研究人员以英语或西班牙语亲自管理。访谈最常在参与者的家中进行，较少在社区空间内进行。用描述性统计量评估项目正态性。知识项目的难度以正确率进行评估。采用验证性因素分析（CFA）评价自我效能感的结构效度。如果验证性因子指数（CFI）> 0.95，近似均方根误差（RMSEA）<0.05，标准化均方根残差（RMSR）<0.05，则认为模型拟合良好。皮尔森相关与消费分数评估标准效度，和组内相关系数（ICC）评估重测信度。在测试的八个知识项目中，只有四个项目的正确答案不到一半。CFA产生了一个5项量表，具有极好的拟合指数（CFI = 0.99; RMSEA = 0.025：SRMR = 0.02）和Cronbach（0.79），重测（ICC = 0.68），以及与意图和SSB消费的显著相关性。在四个意向项目中，有一个与SSB消费显著相关。这项研究提供了证据的有效性的关键结构相关的SSB消费用于成人，这可以提供重要的理论为基础的标志物SSB相关的干预措施的项目评估。在线版本包含补充材料，可通过10.1186/s12889 - 020 - 10073 - 0获得。
Sugar-sweetened beverage (SSB) consumption is an important behavior that can influence individuals’ risk for diabetes, obesity, and other chronic diseases. Nonetheless, there is a lack of valid measures to assess SSB-related constructs. Reliable and valid measures can help evaluate the efficacy of interventions designed to curb SSB consumption. Our aim was to develop a valid and reliable instrument to measure constructs related to SSB consumption in English and Spanish. A cross-sectional survey was conducted among a convenience sample of 150 adult residents of public housing developments in Boston, Massachusetts between July of 2016 and January of 2017. All households from two public housing developments were approached by study staff to solicit participation via door-to-door knocking and posted flyers. We developed questions to measure three SSB-related constructs informed by the Social Cognitive Theory: SSB knowledge, and self-efficacy and intention to act on SSB consumption. The questions were pilot tested in the population, and then administered in-person by bilingual study staff in either English or Spanish. Interviews were conducted most often in the participant’s home and less frequently within a community space. Item normality was assessed with descriptive statistics. Difficulty of knowledge items was assessed with percent correct. Construct validity of self-efficacy items was assessed using confirmatory factor analysis (CFA). A model was considered a good fit if confirmatory factor index (CFI) > 0.95, root mean square error of approximation (RMSEA) < 0.05, and standardized root mean square residual (RMSR) < 0.05. Pearson correlations with consumption scores assessed criterion validity, and intraclass correlation coefficients (ICC) assessed test-retest reliability. Of the eight knowledge items tested, only four items resulted in correct answers less than half of the time. CFA resulted in a 5-item scale with excellent fit indices (CFI = .99; RMSEA = .025: SRMR = .02) and Cronbach’s (0.79), test-retest (ICC = 0.68), and significant correlation with intention and SSB consumption. Of the four intention items, one was significantly correlated with SSB consumption. This study provides evidence for the validity of key constructs related to SSB consumption for use in adults, which could provide important theory-based markers for program evaluations of SSB-related interventions.
