Food allergy (FA) has been shown to have an adverse impact on food allergy quality of life (FAQL). To more fully understand this impact, correlates and predictors of FAQL must be reliably measured. Coping is one such factor. In the present study (n = 200), we sought to adapt the widely used Coping Orientation to Problems Experienced (COPE) Inventory and its 15 distinct strategies to food allergy, named FA-COPE Inventory. More specifically, we propose a long (60-item) and short (30-item) version of the measure.
To examine the robustness of the newly adapted FA-COPE Inventory, we tested whether the 15-factor structure of the adapted version would present good psychometrical properties, using gold standard psychometric techniques. We used Confirmatory Factor Analysis to assess model fit, McDonald's omega, and inter-item correlations to assess reliability, and Pearson's correlation to assess convergent validity with a generic coping measure and satisfaction with FA life.
Our results showed a good model fit (eg, CFI and TLI ≥ .94) for the 15-factor structure of the measure's long and short version. These factors also presented reliability levels aligned with the coping literature. Finally, the majority of the FA-COPE Inventory factors (eg, acceptance) were significantly associated with the generic coping measure and satisfaction with FA life.
Both the long and short adapted FA-COPE Inventory showed a good fit to food allergy issues. These measures can help facilitate the identification of the most commonly used strategies to deal with FA. Their use can lead to a more in-depth understanding of the impact of the coping strategies and how they can help improve the quality of life of those impacted by the disease.
食物过敏（FA）已被证明会对食物过敏生活质量（FAQL）产生不利影响。为了更全面地了解这种影响，必须可靠地测量FAQL的相关因素和预测指标。应对方式就是其中一个因素。在本研究（n = 200）中，我们试图将广泛使用的应对问题经验取向（COPE）量表及其15种不同策略应用于食物过敏领域，命名为食物过敏应对（FA-COPE）量表。更具体地说，我们提出了该量表的长版（60项）和短版（30项）。
为了检验新改编的FA-COPE量表的稳健性，我们使用金标准心理测量技术，测试改编版的15因素结构是否具有良好的心理测量特性。我们使用验证性因素分析来评估模型拟合度，使用麦克唐纳ω系数和项目间相关性来评估信度，并使用皮尔逊相关性来评估与一般应对量表以及对食物过敏生活满意度的收敛效度。
我们的结果表明，该量表长版和短版的15因素结构均具有良好的模型拟合度（例如，CFI和TLI≥0.94）。这些因素的信度水平也与应对方式的文献一致。最后，大多数FA-COPE量表因素（例如，接受）与一般应对量表以及对食物过敏生活的满意度显著相关。
改编后的FA-COPE量表长版和短版均与食物过敏问题拟合良好。这些测量方法有助于确定应对食物过敏最常用的策略。使用这些方法可以更深入地了解应对策略的影响以及它们如何帮助改善受该疾病影响者的生活质量。
