To assess the relative validity of a semi-quantitative food frequency questionnaire (SQFFQ) against 28 day weighed diet records (WDRs).
The SQFFQ was administered to 106 (21 male and 85 female) Japanese dietitians in Aichi Prefecture in autumn, 1996 and four-season consecutive 7 day WDRs were carried out during 1996-1997. We evaluated validity of intakes of 15 foods and 31 macro- and micro-nutrients based on the SQFFQ against those according to 28 day WDRs among 79 Japanese female dietitians.
Mean daily intakes of selected foods and nutrients determined by the SQFFQ were generally equivalent to those measured by 28 day WDRs. Pearson's de-attenuated correlation coefficients (CCs) with log-transformation and energy-adjustment between intakes of selected foods and nutrients quantified by the SQFFQ and 28 day WDRs (minimum-median-maximum) ranged from 0.17 (beverages)-0.52 to 0.74 (rice), and Spearman's rank CCs with energy-adjustment ranged from 0.28 (confectionery)-0.42 to 0.68 (rice). Respective Pearson's CCs for intakes of nutrients were 0.28 (PUFAs)-0.51 to 0.73 (magnesium), and Spearman's rank CCs ranged from 0.23 (n-3 PUFAs)-0.45 to 0.71 (magnesium). Favorably higher agreement for intakes of foods/nutrients was achieved along with lower disagreement.
Satisfactorily higher relative validity was attained in Japanese female dietitians with the SQFFQ. This calibrated questionnaire seems therefore appropriate for administration to Japanese dietitians to clarify associations between diet and health/disease.

评估半定量食物频率问卷（SQFFQ）相对于28天称重饮食记录（WDR）的相对效度。
1996年秋季，对爱知县的106名（21名男性和85名女性）日本营养师进行了SQFFQ调查，并在1996 - 1997年期间连续四个季节进行了为期7天的WDR记录。我们在79名日本女性营养师中，基于SQFFQ评估了15种食物以及31种常量和微量营养素的摄入量相对于28天WDR记录的摄入量的效度。
通过SQFFQ确定的所选食物和营养素的平均每日摄入量通常与28天WDR记录所测量的摄入量相当。经对数转换和能量调整后，SQFFQ量化的所选食物和营养素摄入量与28天WDR记录（最小值 - 中位数 - 最大值）之间的Pearson去衰减相关系数（CCs）范围为0.17（饮料） - 0.52至0.74（大米），经能量调整后的Spearman等级CCs范围为0.28（糖果） - 0.42至0.68（大米）。营养素摄入量的相应Pearson CCs为0.28（多不饱和脂肪酸） - 0.51至0.73（镁），Spearman等级CCs范围为0.23（n - 3多不饱和脂肪酸） - 0.45至0.71（镁）。食物/营养素摄入量的一致性越高，不一致性越低。
在日本女性营养师中，SQFFQ获得了令人满意的较高相对效度。因此，这份经过校准的问卷似乎适合用于对日本营养师进行调查，以阐明饮食与健康/疾病之间的关联。
