Validation of the Hebrew Version of the Eating Assessment Tool-10 (H-EAT-10)

An Evaluation of Psychometric Properties of EAT-10: A Malayalam Version

The Eating Assessment Tool (EAT-10) is a 10-item self-administered questionnaire that assesses the severity of dysphagia symptoms, the impact of dysphagia on quality of life and treatment efficacy. EAT-10 has been adapted into several languages, including Malayalam. However, the information on the psychometric properties of EAT-10 MALAYALAM is not known. Therefore, the study aimed to evaluate the psychometric properties of the EAT-10 MALAYALAM. EAT-10 MALAYALAM questionnaire was administered to two groups of native Malayalam-speaking participants. Group 1 consisted of a total of 110 participants (76 males and 34 females) with a mean age of 52.9 ± 13.5 years diagnosed with oropharyngeal dysphagia. Group 2 consisted of 110 age and gender-matched healthy participants with normal swallow function and no history and symptoms of swallowing disorders. The test-retest reliability was assessed using Spearman's rank correlation coefficient between the test and the retest scores; internal consistency was assessed using Cronbach's alpha, and Known groups validity was evaluated by comparing the EAT-10 MALAYALAM scores between the participants of both groups. The results of Spearman's correlation coefficient showed 0.99, indicating that the EAT-10-MALAYALAM has excellent test-retest reliability. The Cronbach's alpha was 0.94, indicating strong internal consistency. Mann-Whitney U test showed significant differences in the scores of EAT-10-MALAYALAM between the participants of both groups. Therefore, it was inferred that EAT-10-MALAYALAM had good known groups validity. The EAT-10-MALAYALAM is a valid and reliable tool for screening Malayalam-speaking dysphagia patients.

Relationships between oral function, dietary intake and nutritional status in older adults aged 75 years and above: a cross-sectional study

BACKGROUND

Malnutrition is related to impaired oral health and function that causes poor dietary intake, declining the general health of older adults. The role of dietary intake in the association between oral function and nutritional status of Chinese older adults (aged 75 and above) was examined in this cross-sectional study.

METHODS

Through the randomized cluster sampling method, 267 older adults living in rural areas of Qingdao, Shandong (aged 81.4 ± 4.3, 75-94 years) were chosen as the primary research participants. A Mini Nutritional Assessment - Short Form was used to determine nutritional status, and Food Frequency Questionnaire and 24-hour Food Intake Recall were used to assess dietary intake. The oral function was evaluated by analyzing the teeth, oral problems, bite force, tongue pressure, lip sealing pressure, chewing function questionnaire, whole saliva flow rate, 10-Item Eating Assessment Tool, and water swallow test.

RESULTS

Based on the MNA-SF score, it was divided into a well-nourished group and a malnutrition group, with the malnutrition group comprising 40.6% of participants. The participants in the malnutrition group showed a higher rate of xerostomia, lower bite force, tongue pressure, and lip sealing pressure, and higher Chewing Function Questionnaire and 10-Item Eating Assessment Tool scores. Furthermore, their plant fat, iron, cereals and potatoes, vegetables, fruits, and seafood intake were relatively low. The regression model indicated that exercise frequency, stroke, chewing and swallowing function, intake of vegetables and fruits were risk factors for nutritional status of older adults.

CONCLUSION

Malnutrition was relatively common among the Chinese older adults aged 75 and above, and it was significantly correlated with exercise frequency, stroke, chewing and swallowing function, and intake of vegetables and fruits. Therefore, nutrition management should be carried out under the understanding and guidance of the oral function and dietary intake of the older adults.

Development and Evaluation of the Psychometric Properties of the Tamil Version of Eating Assessment Tool - 10 (EAT-10): Preliminary Findings from Persons with Head and Neck Cancer

Aims: This study aimed to develop and evaluate the psychometric properties of the Tamil version of the Eating Assessment Tool (EAT-10). Setting & Study Design: Prospective cross-sectional study on persons with Head and Neck Cancer (HNC) during their follow-up for oncological and swallowing consultation at a tertiary care hospital and healthy individuals recruited from the community. Methods: The study was conducted in two phases: (1) translation and development of the Tamil version of EAT-10 and (2) administration of Tamil EAT-10 to assess internal consistency reliability, test-retest reliability and known-group validity. 92 participants with HNC in the clinical group and 149 healthy adults in the control group completed the Tamil EAT-10. In addition, a subgroup of 20 participants with HNC repeated the questionnaire within a week to assess test-retest reliability. Results: The Cronbach alpha for the 10 items was 0.96 indicating high internal consistency reliability. The test-retest reliability of the individual items and the total scores (r = 0.98) of the Tamil version of EAT-10 were high. The total EAT-10 scores for the HNC group (14.4 ± 11.5) were significantly higher (p < 0.001) than the scores for healthy adults (0.72 ± 2.0). Conclusion: The Tamil version of the EAT-10 developed in this study is a reliable and valid self-administered tool for identifying concerns related to swallowing among persons treated for HNC and healthy adults. This tool can be implemented for clinical practice and research in dysphagia among a Tamil-speaking population.

Diagnostic Accuracy of the Eating Assessment Tool-10 (EAT-10) in Screening Dysphagia: A Systematic Review and Meta-Analysis

The Eating Assessment Tool-10 (EAT-10) is used worldwide to screen people quickly and easily at high risk for swallowing disorders. However, the best EAT-10 cutoff value is still controversial. In this systematic review and meta-analysis, we estimated and compared the diagnostic accuracy of EAT-10 cutoff values of 2 and 3 for screening dysphagia. We searched the PubMed, Web of Science, EMBASE, Cochrane Library, CNKI, WANFANG, and VIP databases from May 2008 to March 2022. The meta-analysis included 7 studies involving 1064 subjects from 7 different countries. Two studies were classified as high quality and five studies as medium quality. With an EAT-10 cutoff value of 2, using flexible endoscopic evaluation of swallowing or video fluoroscopic swallowing study as the gold standard, the pooled sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratio were 0.89 (95% confidence interval [CI] 0.82-0.93), 0.59 (95% CI 0.39-0.77), 2.17 (95% CI 1.38-3.42), 0.19 (95% CI 0.13-0.29), and 11.49 (95% CI 5.86-22.53), respectively. When a cutoff of 3 was used, these values were 0.85 (95% CI 0.68-0.94), 0.82 (95% CI 0.65-0.92), 4.84 (95% CI 1.72-13.50), 0.18 (95% CI 0.07-0.46), and 26.24 (95% CI 5.06-135.95), respectively. Using EAT-10 cutoff values of 2 and 3, the areas under the curve were 0.873 (95% CI 0.82-0.93) and 0.903 (95% CI 0.88-0.93), respectively, showing good diagnostic performance. EAT-10 can be used as a preliminary screening tool for dysphagia. However, a cutoff of 3 is recommended for EAT-10 due to better diagnostic accuracy.

Cross-cultural Adaption, Validation and Factor Analysis of the Persian Version of the Eating Assessment Tool: EAT-10

The eating assessment tool (EAT-10) is a self-reported questionnaire to assess the patient's perception of swallowing difficulties. The aim of this study was to cross-culturally adapt and determine validity and reliability of the Persian version of the EAT-10 (P-EAT-10) in patients with oropharyngeal dysphagia. The EAT-10 was translated into Persian language and cross-culturally adapted. One hundred patients with dysphagia (mean age ± SD = 44.44 ± 14.69 years) participated. The test-retest reliability (time interval = 7 days) was assessed in 50 patients. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and smallest detectable change (SDC) were analyzed. The Persian version of functional oral intake scale (FOIS-P) was also recorded to assess construct validity. One hundred healthy subjects completed the P-EAT-10 for clinical validity. Factor analysis was performed to determine the P-EAT-10 structure. There were no missing responses and floor or ceiling effects. Internal consistency was high (Cronbach's α 0.91). Item-total correlations exceeded acceptable standard of 0.3 for the all items (0.62-0.83). The test-retest reliability was excellent [(ICC)_agreement 0.96]. The SEM and SDC were 2.61 and 7.23, respectively. Construct validity was confirmed by a significant correlation between the P-EAT-10 and FOIS-P scores (r = 0.84). Clinical validity was supported by a significant discrimination between patients and healthy subjects (t = 29.97, P < 0.001). Factor analysis indicated 2 components for the P-EAT-10. The P-EAT-10 is a valid and reliable tool and can be used in clinic and research for the assessment of oropharyngeal dysphagia in Persian-speaking patients.

Discriminant Ability of the Eating Assessment Tool-10 to Detect Swallowing Safety and Efficiency Impairments

OBJECTIVES/HYPOTHESIS

Quick, sensitive dysphagia screening tools are necessary to identify high-risk patients for further evaluation in busy multidisciplinary amyotrophic lateral sclerosis (ALS) clinics. We examined the relationship between self-perceived dysphagia using the validated Eating Assessment Tool-10 (EAT-10) and videofluoroscopic analysis of swallowing safety and efficiency.

STUDY DESIGN

Prospective, observational, longitudinal study.

METHODS

Individuals with ALS completed the EAT-10 and a videofluoroscopic swallowing study. Duplicate, independent, blinded analyses of the validated Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) scale were performed to index swallowing safety and efficiency (mild dysphagia: DIGEST ≥ 1, moderate dysphagia: DIGEST ≥ 2). A between-groups analysis of variance with Games-Howell test for post-hoc pairwise comparisons was performed to examine EAT-10 scores across dysphagia severity levels. Receiver operator characteristic curve analysis, area under the curve (AUC), sensitivity, specificity, positive-negative predictive values (PPV, NPV), and odds ratios (OR) were derived.

RESULTS

Four hundred and thirty five paired EAT-10 and DIGEST scores were analyzed. Mean EAT-10 score was 8.48 (95% confidence interval [CI]: 7.63-9.33). Individuals with dysphagia demonstrated higher EAT-10 scores (mild: 4.1 vs. 11.3, moderate: 6.0 vs. 17.5, P < .001). Mean EAT-10 scores increased across DIGEST levels (D0: 4.1, D1: 7.9, D2: 15.1, D3: 20.4, D4: 39.0). For mild dysphagia, an EAT-10 cut score of 3 was optimal: AUC 0.74 (95% CI: 0.69-0.78; sensitivity: 77%; specificity: 53%; PPV: 71%; NPV: 60%; OR: 3.5). An EAT-10 cut score of 7 optimized detection of moderate dysphagia: AUC 0.83 (95% CI: 0.78-0.87; sensitivity: 81%; specificity: 66%; PPV: 39%; NPV: 93%; OR: 8.1).

CONCLUSION

The EAT-10 is an easy-to-administer dysphagia screening tool with good discriminant ability for use in ALS clinics.

Slovak Translation and Cross-Cultural Validation of the Eating Assessment Tool (EAT10®)

Introduction: The objective of the study was the language adaptation and verification of psychometric properties of the Slovak version of the EAT10® questionnaire. Methods: The original English version of the questionnaire was translated into the Slovak language. The research group included 136 control participants and 51 dysphagic patients. Test−retest reliability, item analysis, internal consistency, construct and clinical validity, and Receiver Operating Characteristic (ROC) analysis were performed to verify the psychometric properties of the Slovak EAT10®. Results: The internal consistency assessed with Cronbach’s alpha is excellent (α = 0.94). Statistical analysis of the Slovak version of EAT10® showed excellent reliability (0.91, p < 0.001) in the test−retest. Through item-to-total correlation, we found out that all items significantly correlated with the overall score in EAT10®. Factor analysis proved a high construct validity. The EAT10® questionnaire was able to reveal a latent variable: a swallowing disorder, which was affecting a group of patients. The clinical validity results confirmed statistically significant differences in the mean scores of the control and dysphagic groups (z = −10.30; p < 0.001). By dividing the dysphagic group into four subgroups (Head and Neck Cancer, Extraesophageal Reflux, Iatrogenic, and Neurological) there were nonsignificant differences in the mean scores of the subgroups. The cut-off value for the Slovak EAT10® is three points. Conclusion: The Slovak EAT10® is a valid and reliable tool designed for the subjective assessment of oropharyngeal dysphagia in patients.

Association between swallowing function, malnutrition and frailty in community dwelling older people

BACKGROUND & AIMS

Swallowing function decreases with age and impacts nutritional state and frailty. The aim of the study was to test the relationship between swallowing function, dysphagia, frailty, malnutrition and depression in community dwelling older participants.

METHODS

Community dwelling older participants (n = 180), were enrolled (74 men aged 75.9 ± 7.8, 65-91 years, and 107 women aged 75.9 ± 8.0, 65-95 years). Swallowing function was assessed by the Test of Mastication and Swallowing Solids (TOMASS) and the Timed Water Swallow Test (TWST). Dysphagia was identified using Hebrew 10-Item Eating Assessment Tool (H-EAT-10). Frailty was assessed by grip strength and the FRAIL Questionnaire. The Mini Nutritional Assessment - Short Form (MNA-SF) was used to identify nutritional status. Depression was screened with the Geriatric Depression Scale - Short Form (GDS-SF).

RESULTS

18.3% of the participants had a score of 3 or above in H-EAT-10, indicating suspected dysphagia. 17.8% of the participants were malnourished or at risk of malnutrition, and 48.3% were defined as frail or pre-frail. The odds of being malnourished/at risk of malnutrition were 3 times greater in those with suspected dysphagia. The odds of being frail/pre-frail were also 3 times greater in those with suspected dysphagia. Moreover, suspected dysphagia and frail/pre-frail health status coincided in 69.7% of participants. Participants that were malnourished/at risk of malnutrition required more masticatory cycles (p < .05) and more time (p < .05) to eat a cracker and drink 150 mL of water (p < .05), and had reduced swallowing capacity (volume/sec) in the TWST (p < .05) than those who were at normal nutritional statues. Similar results were found for frail/pre-frail participants versus robust health status. A decrease in grip strength was associated with increased (worse) frailty score, decreased nutritional score, decreased chewing function in TOMASS and decreased water drinking function in TWST (p < .05). MNA-SF score, age, GDS-SF score and EAT-10 were the best predictors of FRAIL score.

CONCLUSION

A simple multi-dimensional screen should be employed by trained allied health professionals, nurses and their assistants to improve early identification and early referral to relevant health providers in order to provide preventive intervention for dysphagia, nutrition, frailty and depression.

Finnish Version of the Eating Assessment Tool (F-EAT-10): A Valid and Reliable Patient-reported Outcome Measure for Dysphagia Evaluation

Our aim was to validate a Finnish version of the Eating Assessment Tool (F-EAT-10) for clinical use and to test its reliability and validity in a multicenter nationwide study. Normative data were acquired from 180 non-dysphagic participants (median age 57.0 years, 62.2% female). Dysphagia patients (n = 117, median age 69.7 years, 53.0% female) referred to fiberoptic endoscopic evaluation of swallowing (FEES) completed F-EAT-10 before the examination and after 2 weeks. Patients underwent the 100-ml water swallow test (WST) and FEES was evaluated using the following three scales: the Yale Pharyngeal Residue Severity Rating Scale, Penetration-Aspiration Scale, and the Dysphagia Outcome Severity Scale. An operative cohort of 19 patients (median age 75.8 years, 57.9% female) underwent an endoscopic operation on Zenker's diverticulum, tight cricopharyngeal muscle diagnosed in videofluorography, or both. Patients completed the F-EAT-10 preoperatively and 3 months postoperatively. The cut-off score for controls was < 3 (sensitivity 94.0%, specificity 96.1%) suggesting that ≥ 3 is abnormal. Re-questionnaires for test-retest reliability analysis were available from 92 FEES patients and 123 controls. The intraclass correlation coefficient was excellent for the total F-EAT-10 score (0.93, 95% confidence interval 0.91-0.95). Pearson correlation coefficients were strong (p < 0.001) for each of the questions and the total score. Internal consistency as assessed by Cronbach's alpha was excellent (0.95). Some correlations between findings in FEES and 100-ml WST with F-EAT-10 were observed. The change in subjective symptoms of operative patients paralleled the change in F-EAT-10. F-EAT-10 is a reliable, valid, and symptom-specific patient-reported outcome measure for assessing dysphagia among Finnish speakers.

Cultural Adaptation and Validation of Questionnaires for Evaluation of Health-Related Quality of Life with Dysphagia in Different Countries: A Systematic Review

Dysphagia can have devastating and long-lasting effects on the patient's health-related quality of life (HRQoL). In recent years, a number of questionnaires for the evaluation of the HRQoL of patients with dysphagia have been developed and have been adapted for use in different countries and cultures. However, problems may arise in the process of cultural adaptation and validation, which can affect the quality of the questionnaires and their measurements. This study was conducted to systematically summarize the cultural adaptation and validation of questionnaires for the evaluation of dysphagia-related HRQoL in different countries, assessing the varieties, measurement properties, and qualities of these questionnaires, with the aim of identifying the status of their adaptation and validation and ways in which they might be improved. Four databases were searched, and relevant articles were screened, with data from eligible reports extracted and reviewed. The methodological quality of the included articles was evaluated using the QualSyst critical appraisal tool. The HRQoL questionnaires for patients with dysphagia were assessed using the quality criteria for the measurement properties of health status questionnaires proposed by Terwee et al. and Timmerman et al. 29 studies published between 2008 and 2020 were included. The questionnaires described in these 29 studies were translated into 19 languages and culturally adapted to 21 countries. The adapted questionnaires were based on the Swallowing quality of life questionnaire (SWAL-QOL) by Mchorney et al., the Dysphagia Handicap Index (DHI) by Silbergleit et al., the M.D. Anderson Dysphagia Inventory (MDADI) by Chen et al., and the Eating Assessment Tool-10 (EAT-10) by Belafsky et al. It was found that the questionnaires were reliable and valid instruments for the assessment of dysphagia-related HRQoL, but the quality criteria for cultural adaptation and validation were not strictly followed, especially in the categories of criterion validity, agreement, responsiveness, and interpretability. In conclusion, although the questionnaires were found to be both reliable and valid, the quality criteria should be considered and strictly followed in the cultural adaptation and validation process in the future.

Validity and reliability of the French version of Eating Assessment Tool (EAT-10)

OBJECTIVE

To develop a French version of the Eating Assessment Tool (Fr EAT-10) and to assess its internal consistency, reliability and clinical validity.

METHODS

Fifty-six patients referred in the Swallowing Clinics of CHU Saint-Pierre Hospital (Brussels) and EpiCURA hospital (Ath, Belgium) for dysphagia were enrolled and completed fiberoptic endoscopic evaluation of swallowing and videofluoroscopy. Seventy-three asymptomatic subjects were included in the study. To assess reliability, Fr-EAT-10 was completed twice within a 7-day period. Validity was assessed by comparing Fr-EAT-10 scores with the scores of dysphagia handicap index (DHI) in all individuals. Normative value of EAT-10 was calculated and the receiver operating characteristic (ROC) curve was used to determine the best Fr-EAT-10 threshold associated with aspiration.

RESULTS

Fifty-two patients completed the study. Cronbach's alpha was 0.95 indicating a high internal consistency. Test-retest reliability was high in the entire cohort (r_s = 0.921). The correlation between Fr-EAT-10 total scores and DHI was high (r_s = 0.827) indicating a high external validity. Patients had a significant higher score of Fr-EAT-10 than the controls (p < 0.001) exhibiting a high internal validity. The analysis of normative data reported that a score of Fr-EAT-10 > 3 should be considered as abnormal. The correlation between Fr-EAT-10 and the occurrence of aspiration is significant (r_s = 0.327, p < 0.05). According to the ROC curve; aspirations need to be highly suspected for patients with Fr-EAT-10 ≥ 17.

CONCLUSION

The Fr-EAT-10 developed in this study is a reliable and valid self-administered tool in the evaluation of dysphagia in French-speaking patients.
