Comprehensive evaluation of dietary interventions depends on effective and efficient measurement to quantify behavior change. To date, little is known regarding which self-reported measure of dietary intake is most feasible and acceptable for use in evaluation of the effectiveness of diet intervention studies among underserved populations.
This research focused on evaluating feasibility and acceptability of two self-report measures of diet.
Cross-sectional.
PARTICIPANTS/SETTING: Two interviewer-administered 24-hour recalls and a 110-item food frequency questionnaire (FFQ) were administered to both English- and Spanish-speaking participants (n=36) by native English- and Spanish-speaking research assistants. On completion of both dietary assessments, participants were interviewed regarding their preference of measure.
Feasibility for completion of the dietary assessment measures was determined for contacts and retention. Acceptability of the measures was determined through responses to open- and closed-ended questions.
During the 5-month trial, 36 participants were enrolled; 29 completed both intake measures, and 26 completed both measures and the interview. Participants were mainly Hispanic/Latina (72%), with a mean age of 37.0 (±7.6) years. Feasibility targets were met for contacts (1.9, 1.6, 1.8 contact attempts to complete each diet assessment measure with a target of ≤2) and for retention with 89% and 91% completing two 24-hour recalls and the FFQ, respectively. Participants indicated both diet assessment methods were generally acceptable; both positive and negative comments were received for use of the FFQ.
Dietary assessment with the use of 24-hour recalls or an FFQ can be feasible and acceptable among women with low socioeconomic status, although care should be taken to address cultural appropriateness in the selection of the measurement method.
综合评估饮食干预措施取决于有效和高效的测量方法，以量化行为变化。迄今为止，对于在服务不足人群的饮食干预研究中，哪种自我报告的饮食摄入量测量方法最可行和可接受，人们知之甚少。
本研究旨在评估两种饮食自我报告测量方法的可行性和可接受性。
横断面研究。
参与者/设置：通过母语为英语和西班牙语的研究助理，向英语和西班牙语参与者（n=36）同时使用两种访谈式 24 小时回忆法和 110 项食物频率问卷（FFQ）进行调查。在完成两种饮食评估后，通过访谈询问参与者对测量方法的偏好。
通过接触和保留情况来确定饮食评估方法的可行性。通过开放式和封闭式问题的回答来确定测量方法的可接受性。
在 5 个月的试验期间，共招募了 36 名参与者；29 名参与者完成了两种摄入量测量方法，26 名参与者完成了两种测量方法和访谈。参与者主要为西班牙裔/拉丁裔（72%），平均年龄为 37.0（±7.6）岁。接触目标（完成每种饮食评估方法的目标接触次数为 1.9、1.6、1.8 次，接触次数≤2 次）和保留目标（分别有 89%和 91%的参与者完成两次 24 小时回忆和 FFQ）均已达到。参与者表示两种饮食评估方法均普遍可接受；对使用 FFQ 有正反两方面的评价。
使用 24 小时回忆法或 FFQ 进行饮食评估在社会经济地位较低的女性中是可行和可接受的，但在选择测量方法时应注意文化适宜性。
