There is an increasing need for valid, rapid diet screening tools. A significant association between the Prime Diet Quality Score (PDQS) and reduced risk of cardiovascular disease (CVD) has been demonstrated in the US but evidence of its use in Europe is lacking. The aim of this study was to amend the PDQS for a UK/Irish population and determine validity and reliability in those at risk of CVD. Participants were recruited via online adverts across the island of Ireland. The PDQS was amended for a UK/Irish population and participants completed PDQS and reference measure (4-day food diary (FD)) on two occasions. PDQS score was calculated directly from PDQS and indirectly from FDs. Validity was determined using Spearman correlation coefficients (SCCs) (), intraclass correlation coefficients (ICCs) and weighted kappa. Reliability was determined using SCCs (), ICCs, weighted kappa and coefficient of variation. 'Data were available for n = 115 (Month 0) and n = 108 (Month 3) participants for validity and n = 110 for reliability assessment (PDQS completed at both timepoints)'. PDQS score from PDQS was significantly correlated with PDQS score from FDs at months 0 ( = 0.59, < 0.01) and 3 ( = 0.65, < 0.01), with similar associations observed via ICCs. Weighted kappa indicated moderate agreement. PDQS score at month 0 was significantly correlated with PDQS score at month 3 ( = 0.78, < 0.01), with similar associations observed via ICCs. Weighted kappa indicated moderate agreement. Results indicate that the amended PDQS is a valid and reliable tool to determine diet quality in a UK/Irish population at risk of CVD.
对有效、快速的饮食筛查工具的需求日益增加。在美国，主要饮食质量评分（PDQS）与降低心血管疾病（CVD）风险之间存在显著关联，但在欧洲缺乏其应用的证据。本研究的目的是针对英国/爱尔兰人群修订PDQS，并确定其在CVD风险人群中的有效性和可靠性。通过爱尔兰全岛的在线广告招募参与者。针对英国/爱尔兰人群对PDQS进行了修订，参与者两次完成PDQS和参考测量（4天食物日记（FD））。PDQS评分直接从PDQS计算得出，也间接从FDs计算得出。使用斯皮尔曼相关系数（SCCs）（）、组内相关系数（ICCs）和加权kappa来确定有效性。使用SCCs（）、ICCs、加权kappa和变异系数来确定可靠性。“有n = 115名参与者（第0个月）和n = 108名参与者（第3个月）的数据可用于有效性分析，有n = 110名参与者的数据可用于可靠性评估（两个时间点均完成PDQS）”。在第0个月（ = 0.59， < 0.01）和第3个月（ = 0.65， < 0.01），来自PDQS的PDQS评分与来自FDs的PDQS评分显著相关，通过ICCs观察到类似的关联。加权kappa表明一致性中等。第0个月的PDQS评分与第3个月的PDQS评分显著相关（ = 0.78， < 0.01），通过ICCs观察到类似的关联。加权kappa表明一致性中等。结果表明，修订后的PDQS是一种有效且可靠的工具，可用于确定英国/爱尔兰有CVD风险人群的饮食质量。
