背景资料：尽管对家庭食物环境的重要性及其对儿童饮食和社会规范的潜在影响感兴趣，但仍然很少有自我报告清单方法已根据研究人员进行的清单的黄金标准进行验证。本研究的目的是评估标准的有效性和可靠性的“家庭食品供应量清单”（HFAI-C），39个项目的清单，包括类别的水果，蔬菜，零食和drinks.Methods：HFAI-C完成了97名参与者的白色和巴基斯坦血统在英国。通过比较参与者报告的HFAI-C反应与研究人员使用PABAK和加权Kappa统计观察家庭食物供应的数据来确定有效性。还确定了测量可用项目数量（除了存在/不存在）的有效性。重测信度比较重复管理的HFAI-C使用组内相关系数。结果：效度和信度是公平的，以中度整体。对于有效性，平均类别水平PABAK范围从蔬菜的0.31（95% CI：0.25，0.37）到水果的0.44（95% CI：0.40，0.49）。与数量测量相比，项目存在/不存在的评估表现出更高的有效性。当HFAI-C在接近首次给药时重复时，可靠性增加。例如，水果测量可靠性的ICC为0.52（95% CI：0.47，0.56）如果在5个月内重新给药，0.58（95% CI：0.51，0.64）30天内和0.97（95% CI：0.94，1.00），如果在同一天再次给药。结论：总体而言，HFAI-C在白色和南亚参与者的人群中表现出公平至中等的有效性和可靠性。这一评价与以前在多样化程度较低、较富裕人群中对其他清单的研究是一致的。我们的研究支持使用HFAI-C作为一个有用的，虽然不完美的，研究人员进行的库存的代表。在大量多种族样本中使用HFAI-C收集信息的可行性可以促进检查家庭食物供应与种族等暴露以及行为、社会和健康结果等结果的关系。未来使用HFAI-C的工作可以为可能影响健康的可改变影响提供重要见解。
Background: Despite interest in the importance of the home food environment and its potential influence on children's diets and social norms, there remain few self-report checklist methods that have been validated against the gold standard of researcher-conducted inventories. This study aimed to assess the criterion validity and reliability of the 'Home Food Availability Inventory Checklist' (HFAI-C), a 39-item checklist including categories of fruit, vegetables, snacks and drinks.Methods: The HFAI-C was completed by 97 participants of White and Pakistani origin in the UK. Validity was determined by comparing participant-reported HFAI-C responses to data from researcher observations of home food availability using PABAK and weighted kappa statistics. The validity of measuring the amount of items (in addition to presence/absence) available was also determined. Test-retest reliability compared repeated administrations of the HFAI-C using intra-class correlation coefficients.Results: Validity and reliability was fair to moderate overall. For validity, the average category-level PABAK ranged from 0.31 (95 % CI: 0.25, 0.37) for vegetables to 0.44 (95 % CI: 0.40, 0.49) for fruits. Assessment of the presence/absence of items demonstrated higher validity compared to quantity measurements. Reliability was increased when the HFAI-C was repeated close to the time of the first administration. For example, ICCs for reliability of the measurement of fruits were 0.52 (95 % CI: 0.47, 0.56) if re-administered within 5 months, 0.58 (95 % CI: 0.51, 0.64) within 30 days and 0.97 (95 % CI: 0.94, 1.00) if re-administered on the same day.Conclusions: Overall, the HFAI-C demonstrated fair to moderate validity and reliability in a population of White and South Asian participants. This evaluation is consistent with previous work on other checklists in less diverse, more affluent populations. Our research supports the use of the HFAI-C as a useful, albeit imperfect, representation of researcher-conducted inventories. The feasibility of collecting information using the HFAI-C in large, multi-ethnic samples can facilitate examination of home food availability in relation to exposures such as ethnicity and outcomes including behavioural, social and health outcomes. Future work using the HFAI-C could provide important insights into a modifiable influence with potential to impact health.
