Dietary assessment is a challenge in general, and specifically in individuals with intellectual disabilities (ID). This study aimed to evaluate personal digital photography as a method of assessing different aspects of dietary quality in this target group.
Eighteen adults with ID were recruited from community residences and activity centres in Stockholm County. Participants were instructed to photograph all foods and beverages consumed during 1 day, while observed. Photographs were coded by two raters. Observations and photographs of meal frequency, intake occasions of four specific food and beverage items, meal quality and dietary diversity were compared. Evaluation of inter-rater reliability and validity of the method was performed by intra-class correlation analysis.
With reminders from staff, 85% of all observed eating or drinking occasions were photographed. The inter-rater reliability was excellent for all assessed variables (ICC ≥ 0.88), except for meal quality where ICC was 0.66. The correlations between items assessed in photos and observations were strong to almost perfect with ICC values ranging from 0.71 to 0.92 and all were statistically significant.
Personal digital photography appears to be a feasible, reliable and valid method for assessing dietary quality in people with mild to moderate ID, who have daily staff support.
饮食评估通常具有挑战性，对于智力残疾（ID）个体尤其如此。本研究旨在评估个人数码摄影作为评估该目标群体饮食质量不同方面的一种方法。
从斯德哥尔摩县的社区住所和活动中心招募了 18 名 ID 成年人。参与者被要求在观察期间拍摄他们在一天中所吃的所有食物和饮料的照片。照片由两名评分员进行编码。比较了用餐频率、四种特定食物和饮料摄入次数、膳食质量和饮食多样性的观察和照片。通过组内相关系数分析评估了该方法的内部一致性和有效性。
在工作人员的提醒下，观察到的所有进食或饮水情况中有 85%被拍摄下来。除了膳食质量外，所有评估变量的内部一致性均为优秀（ICC≥0.88），而膳食质量的 ICC 为 0.66。照片和观察评估的项目之间的相关性很强，几乎达到完美，ICC 值范围从 0.71 到 0.92，且均具有统计学意义。
个人数码摄影似乎是一种可行、可靠和有效的方法，可用于评估有日常工作人员支持的轻度至中度 ID 人群的饮食质量。
