Purpose

Coeliac disease is a chronic autoimmune condition that significantly impairs health and quality of life if not managed through strict dietary adherence. Given that existing adherence assessment tools are primarily designed for adults, a child-focused, noninvasive scale is needed to accurately evaluate gluten-free diet compliance in the paediatric population. This study aimed to evaluate the Turkish psychometric properties of an adapted Gluten-Free Diet Adherence Survey originally designed for adults but modified for children aged 9–18 years with coeliac disease.

Methods

A cross-sectional, methodological study was conducted with 211 children aged 9–18 years recruited from coeliac associations in Izmir and Istanbul. An expert panel simplified the language of the original adult survey, and a pilot study confirmed its readability and comprehension among children. The validation process employed exploratory and confirmatory factor analyses, internal consistency reliability assessments (Cronbach's α) and response bias evaluations.

Results

Children (mean age 11.95 ± 2.87) achieved an average adherence score of 20 (range: 7–35), indicating moderate compliance with notable barriers to complete adherence. Furthermore, 45% of the participants maintained a gluten-free diet for 5–10 years, highlighting long-term sustainability. Factor loadings ranged from 0.40 to 0.75, and the scale demonstrated excellent model-data fit indices along with acceptable internal consistency (Cronbach's α = 0.797).

Conclusion

The adapted Gluten-Free Diet Adherence Survey is a valid and reliable instrument for assessing dietary compliance in Turkish children with coeliac disease, underscoring the need for targeted interventions to enhance adherence and improve clinical outcomes.

目的：乳糜泻是一种慢性自身免疫性疾病，如果不能通过严格的饮食控制，会严重损害健康和生活质量。鉴于现有的依从性评估工具主要是为成人设计的，需要一个以儿童为中心的无创量表来准确评估儿科人群的无谷蛋白饮食依从性。本研究旨在评估土耳其无麸质饮食依从性调查的心理测量特性，该调查最初是为成人设计的，但对9-18岁患有乳糜泻的儿童进行了修改。方法：从伊兹密尔和伊斯坦布尔的乳糜泻协会招募211名9-18岁的儿童进行横断面方法学研究。一个专家小组简化了原始成人调查的语言，一项初步研究证实了儿童的可读性和理解力。验证过程采用探索性和验证性因子分析、内部一致性信度评估（Cronbach’s α）和反应偏倚评估。结果：儿童（平均年龄11.95±2.87）的平均依从性得分为20分（范围：7-35），表明依从性中等，但存在明显的完全依从性障碍。此外，45%的参与者坚持无麸质饮食5-10年，突出了长期可持续性。因子负荷范围为0.40至0.75，量表显示出良好的模型数据拟合指数以及可接受的内部一致性（Cronbach's α = 0.797）。结论：适应性无麸质饮食依从性调查是评估土耳其乳糜泻儿童饮食依从性的有效和可靠的工具，强调需要有针对性的干预措施来提高依从性和改善临床结果。

Objectives

Large Language Models (LLM) like ChatGPT and Gemini have potential in nutrition applications, but recent studies suggest they provide inaccurate dietary advice. The aim of this study was to evaluate the most commonly used LLMs, ChatGPT and Gemini, for dietary recommendations for patients with irritable bowel syndrome (IBS).

Methods

Various tools were used to assess the responses of LLMs in this study. The Guideline Compliance Score was created using IBS guidelines. The quality of the responses provided by LLMs was assessed using The Global Quality Score (GQS) and Completeness, Lack of Misinformation, Evidence, Appropriateness, Relevance (CLEAR) tool. Understandability and actionability were assessed using the Patient Education Materials Assessment Tool (PEMAT). The readability of ChatGPT and Gemini's responses was evaluated using Flesch Reading Ease (FRE) and Flesch Kincaid Grade Level (FKGL).

Results

This study found that most responses from ChatGPT (70%) and Gemini (57.5%) were compliant with the guidelines, but there was no significant difference in guideline compliance, quality, understandability, actionability, or readability scores (p > 0.05). The CLEAR tool showed a moderate positive correlation with PEMAT actionability (r = 0.467, p = 0.038) and understandability (r = 0.568, p = 0.009), a strong positive correlation with GQS (r = 0.611, p = 0.004). In addition, FRE and FKGL had a strong negative correlation (r = −0.784, p < 0.001), while the Guideline Compliance Score showed a moderate negative correlation with FRE (r = −0.537, p = 0.015).

Conclusions

The study emphasizes the need for further model improvements before relying solely on LLMs in clinical nutrition practice, emphasizing the importance of dietitians' recommendations and the collaboration between AI models and healthcare teams.

目的：像ChatGPT和Gemini这样的大型语言模型（LLM）在营养学应用中具有潜力，但最近的研究表明它们提供的饮食建议不准确。本研究的目的是评估最常用的LLMs， ChatGPT和Gemini，为肠易激综合征（IBS）患者提供饮食建议。方法：采用多种工具评估llm在本研究中的反应。指南遵从性评分是使用IBS指南创建的。法学硕士提供的回答质量使用全球质量评分（GQS）和完整性，缺乏错误信息，证据，适当性，相关性（CLEAR）工具进行评估。使用患者教育材料评估工具（PEMAT）评估可理解性和可操作性。使用Flesch Reading Ease （FRE）和Flesch kinkaid Grade Level （FKGL）对ChatGPT和Gemini的回答的可读性进行评估。结果：本研究发现，ChatGPT（70%）和Gemini（57.5%）的大多数应答者对指南的依从性，但在指南的依从性、质量、可理解性、可操作性和可读性得分上无显著差异（p < 0.05）。CLEAR工具与PEMAT可操作性（r = 0.467, p = 0.038）和可理解性（r = 0.568, p = 0.009）呈中度正相关，与GQS呈强正相关（r = 0.611, p = 0.004）。此外，FRE和FKGL具有很强的负相关（r = -0.784, p）。结论：该研究强调了在临床营养实践中，在完全依赖llm之前，需要进一步改进模型，强调营养师建议以及人工智能模型与医疗团队之间合作的重要性。

Objective

Despite potential health benefits, workplace health promotion programmes still remain limited and varied. This study aimed to evaluate the effectiveness of a Mediterranean Diet (MD)-based intervention in improving the eating habits and the effects on anthropometric characteristics in a sample of University of Torino employees.

Methods

The study comprised 203 university employees (mean age of 47.1 ± 9.2 years, 66% females). At baseline (T0), MD adherence was assessed through the validated Medi-Lite questionnaire, anthropometric characteristics of height, weight and waist circumference were measured and body mass index (BMI) and waist to height ratio (WHtR) derived. The same measurements were repeated after 4 months (T1) to evaluate quantitative and qualitative changes in diet and anthropometric indicators.

Results

After the intervention, the sample showed a significant (p < 0.05) increase in adherence to the MD (T0 = 12.4 ± 2.2 vs. T1 = 13.0 ± 2.0) with higher consumption of vegetables (+12.8%), legumes (+10.3%) and fish (+10.8%). While no significant differences for body weight (−0.2 ± 2.3 kg) and BMI (−0.1 ± 0.9 kg/m²) were observed, a significant decrease in waist circumference (−1.3 ± 4.5 cm) and WHtR (−0.01 ± 0.03) emerged. Furthermore, improvements in MD adherence were associated with a lower risk of metabolic and cardiovascular diseases (according to WHtR) and vice versa.

Conclusion

The nutritional intervention significantly enhanced MD adherence and increased the consumption of its key food groups, including vegetables, legumes, and fish, while reducing waist circumference, WHtR and related risk factors.

目标：尽管有潜在的健康益处，但工作场所健康促进方案仍然有限且种类繁多。本研究旨在评估地中海饮食（MD）干预在改善饮食习惯方面的有效性，以及对都灵大学员工样本的人体测量特征的影响。方法：203名高校职工（平均年龄47.1±9.2岁，女性66%）为研究对象。在基线（T0），通过有效的Medi-Lite问卷评估MD依从性，测量身高、体重和腰围的人体测量特征，并得出体重指数（BMI）和腰高比（WHtR）。4个月（T1）后重复相同的测量，以评估饮食和人体测量指标的定量和定性变化。结论：营养干预显著增强了MD的依从性，增加了其主要食物组（包括蔬菜、豆类和鱼类）的摄入量，同时降低了腰围、腰围比和相关危险因素。

Introduction

Nutrition information practice is fundamental to the process of nutritional self-management for people living with Type 2 diabetes (PLWT2DM). Lay-led, peer support groups have been proposed as a mechanism offering a source of nutrition information. However, there is limited research exploring how support groups facilitate nutrition information practices in PLWT2DM. The aim of this study was to explore the accessibility, acceptability and effectiveness of lay-led peer support groups in the nutrition information practice of PLWT2DM.

Methods

The study took a mixed methods qualitative approach through the lens of practice theory and information practice. Twenty participants (19 were PLWT2DM and one partner) were interviewed following a 4-week diary data collection period where peer support interactions relating to nutrition information practices were recorded by participants. Data were analysed using thematic analysis.

Results

Participants used their experiences of advice from a dietitian and structured education sessions to emphasise the relative influence of peer support groups on their nutrition information practices. Particularly their accessibility, ongoing nature and facilitatory environment enabling social interactions. However, key competencies participants needed were feeling that diabetes was an embodied (integrated) part of everyday life, group communication skills and facilitation skills (considered essential for group leaders).

Conclusion

Peer support groups provide a useful addition to the nutrition information landscape of PLWT2DM. However, the stage of disease embodiment (integration) and skills in social interaction impacted on their perceived effectiveness. Dietitians need to consider the benefit and potential longevity of peer support for PLWT2DM particularly since the COVID-19 pandemic, as a shift towards online formats for peer support groups have changed their availability and possible effectiveness.

营养信息实践是2型糖尿病（PLWT2DM）患者营养自我管理的基础。外行人领导的同伴支持小组被提议作为提供营养信息来源的机制。然而，关于支持团体如何促进PLWT2DM患者营养信息实践的研究有限。本研究的目的是探讨外行人领导的同伴支持小组在PLWT2DM营养信息实践中的可及性、可接受性和有效性。方法：通过实践论和信息实践的视角，采用混合方法定性研究。在为期4周的日记数据收集期后，对20名参与者（19名为PLWT2DM和1名伴侣）进行了访谈，参与者记录了与营养信息实践相关的同伴支持互动。采用专题分析对数据进行分析。结果：参与者利用他们从营养师那里获得建议的经验和结构化的教育课程来强调同伴支持小组对他们营养信息实践的相对影响。特别是它们的可及性、持续性和促进社会互动的环境。然而，参与者需要的关键能力是感觉糖尿病是日常生活的一个体现（综合）部分，团队沟通技巧和促进技能（被认为是团队领导者必不可少的）。结论：同伴支持小组为PLWT2DM患者的营养信息提供了有用的补充。然而，疾病体现阶段（整合）和社会交往技能对他们的感知有效性有影响。特别是自2019冠状病毒病大流行以来，营养师需要考虑同伴支持对PLWT2DM的益处和潜在的持久性，因为同伴支持小组向在线形式的转变改变了它们的可用性和可能的有效性。

Introduction

Estimating food intake in children is a critical part of obesity prevention and nutrition intervention studies. Accurate and convenient methods to measure food intake among preschool children attending early childcare centers (ECCs) are lacking and digital photography may be a convenient option but needs to be validated in the childcare setting. This pilot study assessed the validity of weighed and digital photography plate waste methods.

Methods

Weighed and digital photography plate waste methods were used to estimate food intake during lunch for three consecutive days. Pre-consumption weight of each food was measured in grams. Weighed foods were assembled on a tray and photos were taken. Post-consumption weights and photos were taken for comparison. Two trained research assistants independently estimated food consumption at 10% intervals for the digital photography method; differences in pre- and post-weights were used for weighed method. Food consumption was measured by the difference in grams or estimated percentage in pre-and post-meal weights and photos, respectively. Validity was measured using linear mixed models and Bland Altman regressions to assess differences between digital photography and weighed measurements.

Results

Participants were 41 children (mean age 3.86 ± 0.51, 84% Hispanic/Latino, 58.5% females) enrolled in two Head Start centers. Linear mixed model assessment found no significant difference between macro- or micronutrients, or food groups between the two methods. Bland Altman regression revealed a high level of agreement between weighed and digital photography methods for macronutrients, micronutrients, and food groups.

Conclusion

Weighed and digital photography plate waste methods yield similar results, and both are valid methods to assess food intake in pre-school aged children to aid in intervention studies along with evaluating menu quality. Choice of assessment methods depends on budget, time, equipment, expertise, and training.

儿童食物摄入量的估算是肥胖预防和营养干预研究的重要组成部分。缺乏准确方便的方法来测量学龄前儿童在早期托儿中心（ECCs）的食物摄入量，数码摄影可能是一个方便的选择，但需要在托儿环境中进行验证。这项初步研究评估了称重和数码摄影底片废物处理方法的有效性。方法：采用称重法和数码照相底片法对连续3天的午餐食物摄取量进行估算。每种食物的食用前重量以克为单位。称重后的食物放在托盘上并拍照。消费后的体重和照片进行比较。两名训练有素的研究助理以10%的间隔独立估计数字摄影方法的食物消耗量；称重法采用前后体重差异。食物消耗分别通过餐前和餐后体重和照片的克数差异或估计百分比来衡量。使用线性混合模型和Bland Altman回归来评估数字摄影和称重测量之间的差异。结果：41名儿童（平均年龄3.86±0.51岁，84%为西班牙裔/拉丁裔，58.5%为女性）参加了两个启智中心。线性混合模型评估发现，两种方法之间的宏量或微量营养素或食物组之间没有显著差异。Bland Altman回归揭示了大量营养素、微量营养素和食物组的称重和数码摄影方法之间的高度一致。结论：称重法和数码照相法的盘子浪费产生相似的结果，两者都是评估学龄前儿童食物摄入量的有效方法，有助于干预研究以及评估菜单质量。评估方法的选择取决于预算、时间、设备、专业知识和培训。

Background and Aims

One of the most widely used classification systems for ultra-processed foods is NOVA. However, it lacks adaptability to the Greek dietary context and market. Thus, the aim was to develop a valid and easy-to-use tool, friendly to health professionals, which, in combination with the existing nutritional assessment tools, will be able to determine the level of UPF consumption and dietary habits of young Greek adults.

Methods

For the GR-UPFAST (GReek Ultra Processed Food intake ASsessment Tool) design, a multi-station procedure was followed; literature review, field visits in food markets, classification, and definition of food types and portions. Four experienced nutritionists conducted content and face validity. Then, a cross-sectional study in 220 young adults, aged 18–30, both males and females was performed. Internal consistency of the GR-UPFAST was assessed using Cronbach's alpha. Criterion and predictive validity were evaluated through Spearman's correlations with MedDietScore and body weight. Construct validity was assessed with confirmatory factor analysis.

Results

Total Cronbach's α value was 0.766. Cronbach's α values if an item deleted ranged from 0.720 to 0.770, indicating overall good and stable internal consistency. Confirmatory factor analysis confirmed the one-dimension GR-UPFAST's structure, and the very good model fit (x²/df = 0.61). GR-UPFAST score was negatively correlated with the MedDietScore (rho = −0.162, p = 0.016) and positively with body weight (rho = 0.140, p = 0.039).

Conclusions

GR-UPFAST appears to be a practical and valid tool for assessing UPF consumption among Greek younger adults. It may enhance comprehension of nutrition in younger adults and probably in other Greek and Mediterranean populations.

背景与目的：NOVA是超加工食品中应用最广泛的分类系统之一。然而，它缺乏对希腊饮食环境和市场的适应性。因此，目的是开发一种有效和易于使用的工具，对卫生专业人员友好，与现有的营养评估工具相结合，将能够确定希腊年轻人的UPF消费水平和饮食习惯。方法：采用GR-UPFAST（希腊超加工食品摄入评估工具）设计，采用多站程序；文献回顾，食品市场实地考察，食品种类和份量的分类和定义。四位经验丰富的营养学家进行了内容效度和外观效度的测试。然后，对220名年龄在18-30岁之间的年轻人进行了横断面研究，其中既有男性也有女性。采用Cronbach’s alpha评价GR-UPFAST的内部一致性。通过Spearman与MedDietScore和体重的相关性评估标准效度和预测效度。采用验证性因子分析评估结构效度。结果：总Cronbach’s α值为0.766。删除后的Cronbach’s α值在0.720 ~ 0.770之间，表明内部一致性总体良好且稳定。验证性因子分析证实了GR-UPFAST的一维结构，模型拟合良好（x2/df = 0.61）。GR-UPFAST评分与MedDietScore呈负相关（rho = -0.162, p = 0.016），与体重呈正相关（rho = 0.140, p = 0.039）。结论：GR-UPFAST似乎是评估希腊年轻人UPF消费的实用有效的工具。它可能会提高年轻人对营养的理解，也可能是其他希腊和地中海人口。

Background

This study aimed to evaluate the effect of evidence-based training on enteral nutrition practices provided to palliative care nurses on their knowledge levels.

Materials and Methods

A quasi-experimental study, one-group pre-test and post-test design was employed from February to April 2024. The study involved registered nurses (46) from 5 public hospitals, representing all palliative care units in a northeastern province of Turkey. The training was conducted in a 2-h session. Data were collected using the ‘Evidence-Based Enteral Nutrition Training Information Form for Palliative Care Nurses’, designed by the researcher, both before (pre-test) and 1 month after (post-test) the training.

Results

Significant increases in correct response rates with a large effect size were observed in half of the questions concerning indications for enteral nutrition (p = 0.180, p = 0.001 Cohen's h = 1.40), all questions regarding enteral feeding tubes, and more than half of the questions related to enteral nutrition applications, with large effect sizes (p = 0.001 Cohen's h = 1.40, p = 0.001 Cohen's h = 1.12, p = 0.001 Cohen's h = 1.23, p = 0.001 Cohen's h = 0.52,) and potential complications, with medium to large effect sizes (p = 0.022 Cohen's h = 0.42, p = 0.001 Cohen's h = 0.56, p = 0.500). While the response rates for questions about complications of enteral nutrition solutions improved post-training, the differences were not statistically significant (p = 0.804, p = 0.076).

Conclusions

The educational intervention substantially improved palliative care nurses' knowledge regarding enteral nutrition, with effect sizes ranging from medium to large. This study highlights the importance of maintaining nurses' knowledge in alignment with current guidelines, particularly in specialized fields like palliative care. The results should be interpreted cautiously due to the single-group design and limited sample size.

背景：本研究旨在评估姑息护理护士肠内营养实践的循证培训对其知识水平的影响。材料与方法：采用准实验研究，一组前测和后测设计，时间为2024年2 - 4月。该研究涉及来自5家公立医院的注册护士（46名），代表了土耳其东北部省份的所有姑息治疗单位。培训以2小时的时间进行。数据收集采用研究者设计的“姑息护理护士循证肠内营养培训信息表”，收集时间包括培训前（测试前）和培训后1个月（测试后）。结果:显著增加正确反应率,观察效果减半的问题关于适应症肠内营养(p = 0.180, p = 0.001科恩的h = 1.40),所有的问题关于喂养管,和超过一半的问题相关的肠内营养的应用,与大尺度效应(p = 0.001科恩的h = 1.40, p = 0.001科恩的h = 1.12, p = 0.001科恩的h = 1.23, p = 0.001科恩的h = 0.52)和潜在的并发症,具有中大型效应量（p = 0.022 Cohen's h = 0.42, p = 0.001 Cohen's h = 0.56, p = 0.500）。虽然训练后肠内营养液并发症问题的回复率有所提高，但差异无统计学意义（p = 0.804, p = 0.076）。结论：教育干预显著提高了姑息护理护士对肠内营养的认识，其效应量从中到大不等。这项研究强调了保持护士知识与当前指南保持一致的重要性，特别是在姑息治疗等专业领域。由于单组设计和有限的样本量，结果应谨慎解释。

Introduction

Accurate dietary assessment is essential for understanding nutrition-related health risks in migrant populations. The Australian Eating Survey Food Frequency Questionnaire (AES) is widely used but has not yet been validated among South Asian (SA) migrants, the second-largest migrant group in Australia. This study aimed to evaluate the comparative validity of the AES for estimating nutrient intake within this culturally diverse group.

Methods

A cross-sectional validation study was conducted among SA adults residing in Victoria, Australia. Participants completed the AES and a 3-day weighed food record (WFR). Energy and nutrient estimates derived from both methods were compared using paired t-tests or Wilcoxon signed-rank tests. Associations between values from each method were tested via Pearson/Spearman correlations, and levels of agreement were evaluated via Bland–Altman analysis.

Results

218 participants completed the initial questionnaire (63.0% response rate), with 21 providing complete dietary data. Moderate agreement between AES-FFQ and WFR was observed for protein (p = 0.024), niacin (p = 0.029), vitamin B12 (p = 0.030), and beta-carotene (p = 0.036). However, discrepancies were identified for fats (p = 0.98), energy (p = 0.246), added sugar (p = 0.573), and sodium (p = 0.688), alongside inconsistent estimation for several micronutrients. Bland–Altman plots demonstrated systematic underestimation by AES-FFQ for key nutrients.

Conclusion

The AES demonstrates acceptable validity for certain nutrients among SA migrants but shows significant limitations in accurately estimating intake of fats, energy, sugar, sodium, and some micronutrients. These findings underscore the need for culturally tailored dietary assessment tools or refined adaptations of existing instruments to better capture dietary patterns in this population.

准确的饮食评估对于了解流动人口中与营养相关的健康风险至关重要。澳大利亚饮食调查食物频率问卷（AES）被广泛使用，但尚未在澳大利亚第二大移民群体南亚（SA）移民中得到验证。本研究旨在评估AES在估算这一多元文化群体的营养摄入量方面的相对有效性。方法：对居住在澳大利亚维多利亚州的南非成年人进行了横断面验证研究。参与者完成了AES和3天称重食物记录（WFR）。使用配对t检验或Wilcoxon符号秩检验比较两种方法得出的能量和营养估计值。通过Pearson/Spearman相关性测试每种方法值之间的关联，并通过Bland-Altman分析评估一致性水平。结果：218名参与者完成了初始问卷（63.0%的回复率），其中21名提供了完整的饮食数据。在蛋白质（p = 0.024）、烟酸（p = 0.029）、维生素B12 （p = 0.030）和β -胡萝卜素（p = 0.036）方面，AES-FFQ与WFR之间存在中等程度的一致性。然而，在脂肪（p = 0.98）、能量（p = 0.246）、添加糖（p = 0.573）和钠（p = 0.688）方面发现了差异，同时对几种微量营养素的估计也不一致。Bland-Altman图显示AES-FFQ对关键营养素的系统性低估。结论：AES对南澳移民的某些营养素具有可接受的有效性，但在准确估计脂肪、能量、糖、钠和一些微量营养素的摄入量方面存在明显的局限性。这些发现强调有必要根据文化量身定制饮食评估工具或对现有工具进行改进，以更好地捕捉这一人群的饮食模式。

Background

Although studies have demonstrated ChatGPT′s potential as an AI nutritionist, no research has yet investigated the factors influencing its adoption and actual use of ChatGPT as a virtual nutrition assistant among dietetic students.

Objective

In this study, we examined factors influencing ChatGPT′s actual usage among dietetic students, focusing on the role of trust in its adoption for academic and clinical nutrition tasks.

Methods

A web-based survey was conducted among dietetic students in Taiwan with prior experience using ChatGPT. The survey was designed based on an extended Technology Acceptance Model. Partial least squares structural equation modeling was applied to assess the structural model and test hypotheses.

Results

In total, 150 dietetic students (82% female, mean age = 20.66 ± 3.96 years) completed the survey. Regarding specific nutrition-related tasks, ChatGPT′s actual use scores were highest for “understanding nutrition knowledge” and “analyzing the calorie and nutrient content of a dietary record”, while lower scores were observed for “preparing for the registered dietitian exam” and “analyzing patients′ nutritional status and providing dietary recommendations”. The PLS-SEM model respectively explained 28.2% and 44.6% of the variance in actual use (AU) for academic and clinical nutrition tasks. Trust (TR) and behavioral intention to use (BIU) independently predicted AU for academic tasks, including understanding nutrition knowledge (BIU: β = 0.336 and TR: β = 0.341) and preparing for the registered dietitian exam (BIU: β = 0.310 and TR: β = 0.311). For clinical tasks, such as analyzing the calorie and nutrient contents of a dietary record (β = 0.523) and evaluating patients′ nutritional status (β = 0.381), TR was the sole significant predictor.

Conclusions

Trust is a key factor driving the adoption and actual use of ChatGPT as an AI nutrition assistant, particularly in clinical nutrition tasks.

背景：虽然研究已经证明了ChatGPT作为人工智能营养师的潜力，但尚未有研究调查影响其在营养学学生中作为虚拟营养助手的采用和实际使用的因素。目的：在本研究中，我们考察了影响ChatGPT在营养专业学生中实际使用的因素，重点是信任在其在学术和临床营养任务中采用中的作用。方法：采用网路调查的方式，对曾使用ChatGPT的台湾学生进行问卷调查。该调查是基于扩展的技术接受模型设计的。采用偏最小二乘结构方程模型对结构模型进行评估，并对假设进行检验。结果：共有150名学生完成调查，其中女性82%，平均年龄20.66±3.96岁。在具体的营养相关任务中，ChatGPT在“了解营养知识”和“分析膳食记录的卡路里和营养素含量”方面的实际使用得分最高，而在“准备注册营养师考试”和“分析患者营养状况并提供饮食建议”方面的实际使用得分较低。PLS-SEM模型分别解释了学术和临床营养任务中实际使用（AU）差异的28.2%和44.6%。信任（TR）和行为使用意向（BIU）独立预测学业任务的AU，包括理解营养知识（BIU: β = 0.336, TR: β = 0.341）和准备注册营养师考试（BIU: β = 0.310, TR: β = 0.311）。对于临床任务，如分析饮食记录的卡路里和营养成分含量（β = 0.523）和评估患者的营养状况（β = 0.381）， TR是唯一的显著预测因子。结论：信任是推动ChatGPT作为人工智能营养助手的采用和实际使用的关键因素，特别是在临床营养任务中。

Introduction

Uncovering the impact of medical nutrition therapy (MNT) on resulting outcomes depends on high quality standardized documentation that can be analyzed. A valid, reliable tool is necessary to evaluate documentation for quality. The Nutrition Care Process-Quality Evaluation and Standardization Tool (NCP-QUEST) was developed to evaluate nutrition care documentation quality including NCP chains, component linkages, and reassessment.

Methods

Our aim was to determine the validity and reliability of the NCP-QUEST in a sample of people with diabetes. This study is a secondary analysis of Diabetes Registry data from the Academy of Nutrition and Dietetics Health Informatics Infrastructure (ANDHII). Sample size was derived from the Diabetes Registry data from ANDHII collected between May 2017 and June 2019 (n = 15 patient cases, 30 total encounters). Main outcomes are the validity and reliability of the NCP-QUEST. Patient cases were audited using the NCP-QUEST. Validity was evaluated using content validity index (CVI) calculations, and reliability was determined using Krippendorff's alpha (α) coefficient and interrater correlation coefficient (ICC).

Results

The NCP-QUEST was found to have high validity (relevance: S-CVI-UA = 0.96, S-CVI-Ave=0.98; clarity: S-CVI-UA = 0.92, S-CVI-Ave=0.96), moderate interrater reliability (α = 0.6684, ICC = 0.72), and low to moderate intra-rater reliability (rater 1 α = 0.8598, rater 2 α = 0.3194). The NCP-QUEST exposed gaps in documentation of clear NCP links.

Conclusion

The NCP-QUEST was found to be valid and reliable in a sample of people with diabetes. Revisions should be considered to improve agreement reliability before incorporation into practice.

简介：揭示医学营养治疗（MNT）对结果的影响取决于可分析的高质量标准化文件。一个有效的、可靠的工具对于评估文档的质量是必要的。开发了营养护理过程质量评估和标准化工具（NCP- quest）来评估营养护理文件的质量，包括NCP链、组件链接和重新评估。方法：我们的目的是确定NCP-QUEST在糖尿病患者样本中的有效性和可靠性。本研究是对营养与饮食健康信息基础设施（ANDHII）学会糖尿病登记数据的二次分析。样本量来自2017年5月至2019年6月收集的ANDHII糖尿病登记数据（n = 15例患者，30例总接触）。主要结果为NCP-QUEST的效度和信度。使用NCP-QUEST对患者病例进行审计。采用内容效度指数（CVI）计算效度，采用Krippendorff α (α)系数和inter - correlation系数（ICC）确定信度。结果：NCP-QUEST具有高效度（相关性：S-CVI-UA =0.96, S-CVI-Ave=0.98；清晰度：S-CVI-UA = 0.92, S-CVI-Ave=0.96）、中等效度（α = 0.6684, ICC = 0.72）和中低效度（α 1 = 0.8598, α 2 = 0.3194）。NCP- quest暴露了文件中明确的NCP联系的漏洞。结论：NCP-QUEST在糖尿病患者样本中是有效和可靠的。在纳入实践之前，应考虑修订以提高协议的可靠性。
