To investigate the psychometric properties, validity and reliability of a newly developed measure of food insecurity, the Household Food and Nutrition Security Survey (HFNSS), among an Australian population.
Cross-sectional study.
Metropolitan areas of Melbourne, Australia, identified as very high, high or medium vulnerability in the 2008 Vulnerability Assessment for Mortgage, Petrol and Inflation Risks and Expenditure index.
A convenience sample of 134 adults (117 females and fifteen males, aged over 18 years).
Rasch modelling and factor analysis identified four items for exclusion. The remaining items yielded excellent reliability among the current sample and assessed three underlying components: the adult experience of food insecurity (component one), initial/periodic changes to children's food intakes (component two) and progressive/persistent decreases in children's food intakes (component three). Compared with the widely used US Department of Agriculture Food Security Survey Module, the HFNSS identified a significantly higher proportion of food insecurity; this is likely due to the HFNSS's identification of food insecurity due to reasons other than (and including) limited financial access.
The HFNSS may be a valid and reliable tool for the assessment of food insecurity among the Australian population and provides a means of assessing multiple barriers to food security beyond poor financial access (which has been identified as a limitation of other existing tools). Future research should explore the validity and reliability of the tool among a more representative sample, as well as specifically among vulnerable population subgroups.
研究一种新开发的食物不安全度量衡——家庭食物和营养安全调查（HFNSS）在澳大利亚人群中的心理计量特性、有效性和可靠性。
横断面研究。
澳大利亚墨尔本的大都市区，在 2008 年抵押贷款、汽油和通货膨胀风险以及支出指数的脆弱性评估中被确定为非常高、高或中危。
一个方便的 134 名成年人样本（117 名女性和 15 名男性，年龄在 18 岁以上）。
Rasch 模型和因子分析确定了四项需要排除的项目。其余项目在当前样本中具有极好的可靠性，并评估了三个潜在的组成部分：成人经历的食物不安全（组成部分一）、儿童食物摄入量的初始/定期变化（组成部分二）和儿童食物摄入量的逐渐/持续减少（组成部分三）。与广泛使用的美国农业部粮食安全调查模块相比，HFNSS 确定了一个明显更高比例的粮食不安全；这可能是由于 HFNSS 确定的粮食不安全是由于除了（包括）有限的财务渠道之外的其他原因造成的。
HFNSS 可能是评估澳大利亚人群食物不安全的有效和可靠工具，并提供了一种评估除了财务渠道不良之外的多种食物不安全障碍的方法（这被认为是其他现有工具的一个局限性）。未来的研究应该在更具代表性的样本中，以及在脆弱人群亚组中，探索该工具的有效性和可靠性。
