目的：饮食评估的一个迫切需要是开发短期工具，提供有效的评估饮食质量的时间有限的设置中使用。本研究评估了短期饮食质量筛选（sDQS）和短期地中海饮食筛选（bMDSC）问卷的同时和结构效度。设计：通过比较三个饮食质量指数-饮食质量指数（DQI），改良地中海饮食评分（mMDS）和抗氧化剂评分（ANTOX-S）-从两份问卷中获得，并从12个月内多次24小时召回中获得。结构效度通过多次24小时回忆记录的平均营养摄入量与短筛选者得出的DQI、mMDS和ANTOX-S之间的相关性来证明。设置：两份短问卷均对102名来自西班牙人口调查的参与者进行管理。结果：DQI、mMDS和ANTOX-S相关（P
Objective: An urgent need in dietary assessment is the development of short tools that provide valid assessments of dietary quality for use in time-limited settings. The present study assessed concurrent and construct validity of the short Diet Quality Screener (sDQS) and brief Mediterranean Diet Screener (bMDSC) questionnaires.Design: Relative validity was measured by comparing three dietary quality indices - the Diet Quality Index (DQI), the modified Mediterranean Diet Score (mMDS) and the Antioxidant Score (ANTOX-S) - derived from the two questionnaires with those from multiple 24 h recalls over 12 months. Construct validity was demonstrated by correlations between average nutrient intake recorded on multiple 24 h recalls and the DQI, mMDS and ANTOX-S derived by the short screeners.Setting: Both short questionnaires were administered to 102 participants recruited from a population-based survey in Spain.Results: DQI, mMDS and ANTOX-S correlated (P
