Home food availability (HFA) checklists can be completed by self-report to assess the home food environment. Checklists developed for Black/African American (B/AA) and Hispanic/Latinx (H/L) households are seldom validated against objective approaches such as exhaustive in-home food inventories. This study validated a self-report HFA checklist developed for B/AA and H/L households (n = 97) against researcher-completed HFA checklists verified by exhaustive in-home food inventories. Mean estimates of sensitivity, specificity, and area of the receiver operating curve (ROC), and interrater agreement (Gwet AC1) were calculated to examine the accuracy and agreement of self-reported checklists against direct observation of individual food items. Mean differences in HFA food group scores were compared (self-report vs observed) to examine group-level relative validity. The predictive validity of this self-reported measure on observed scores and dietary intake were also examined with linear regression. The average values for ROC area (average of sensitivity and specificity) ranged from acceptable (0.76 for sweets) to excellent (0.81 for vegetables, fruits). Average interrater agreement values ranged from moderate (0.41-0.60: sweets) to substantial (0.61-0.79: vegetables, fruit, SSBs, savory foods). Self-reported mean scores, compared to observed scores, were higher for vegetables (mean diff: 1.04) and lower for sweets (mean diff: 0.38, p = 0.01), but regression analyses demonstrated that self-reported scores were good predictors of observed scores with absolute error (based on standard deviation of residuals) ranging from ±1.27 to 1.69 points. Self-reported scores also predicted multiple aspects of dietary intake but more so among H/L households. In conclusion, the HFA checklist obtained via self-report performed well based on multiple indicators of validity suggesting that this self-reported measure can be used to assess home food environments among of B/AA and H/L households.
家庭食物供应（HFA）清单可通过自我报告完成，以评估家庭食物环境。针对黑人和西班牙裔/拉丁裔（B/AA 和 H/L）家庭开发的清单很少通过详尽的家庭食品清单等客观方法进行验证。本研究通过详尽的家庭食品清单验证了针对 B/AA 和 H/L 家庭（n=97）开发的自我报告 HFA 清单，验证了研究人员完成的 HFA 清单。使用接收者操作曲线（ROC）的灵敏度、特异性和面积的均值估计值，以及评分者间一致性（Gwet AC1）来检查自我报告清单与个体食物直接观察之间的准确性和一致性。比较 HFA 食物组得分的均值差异（自我报告与观察），以检查组级相对有效性。还使用线性回归检查了该自我报告指标对观察得分和饮食摄入的预测有效性。ROC 面积（灵敏度和特异性的平均值）的平均值范围从可接受（甜食为 0.76）到优秀（蔬菜为 0.81）。平均评分者间一致性值范围从中度（0.41-0.60：甜食）到高度（0.61-0.79：蔬菜、水果、SSB、咸味食品）。与观察得分相比，自我报告的平均得分更高的是蔬菜（平均差值：1.04），更低的是甜食（平均差值：0.38，p=0.01），但回归分析表明，自我报告的得分是观察得分的良好预测指标，绝对误差（基于残差标准差）范围从±1.27 到 1.69 分。自我报告的得分还预测了饮食摄入的多个方面，但在 H/L 家庭中更为明显。总之，通过多种有效性指标表明，通过自我报告获得的 HFA 清单表现良好，这表明该自我报告的测量方法可用于评估 B/AA 和 H/L 家庭的家庭食物环境。
