AbstractThe lack of a Swedish patient-reported outcome instrument for eosinophilic esophagitis (EoE) has limited the assessment of the disease. The aims of the study were to translate and validate the Eosinophilic Esophagitis Activity Index (EEsAI) to Swedish and to assess the symptom severity of patients with EoE compared to a nondysphagia control group. The EEsAI was translated and adapted to a Swedish cultural context (S-EEsAI) based on international guidelines. The S-EEsAI was validated using adult Swedish patients with EoE (n = 97) and an age- and sex-matched nondysphagia control group (n = 97). All participants completed the S-EEsAI, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Oesophageal Module 18 (EORTC QLQ-OES18), and supplementary questions regarding feasibility and demographics. Reliability and validity of the S-EEsAI were evaluated by Cronbach’s alpha and Spearman correlation coefficients between the domains of the S-EEsAI and the EORTC QLQ-OES18. A test–retest analysis of 29 patients was evaluated through intraclass correlation coefficients. The S-EEsAI had sufficient reliability with Cronbach’s alpha values of 0.83 and 0.85 for the “visual dysphagia question” and the “avoidance, modification and slow eating score” domains, respectively. The test–retest reliability was sufficient, with good to excellent intraclass correlation coefficients (0.60–0.89). The S-EEsAI domains showed moderate correlation to 6/10 EORTC QLQ-OES18 domains, indicating adequate validity. The patient S-EEsAI results differed significantly from those of the nondysphagia controls (p < 0.001). The S-EEsAI appears to be a valid and reliable instrument for monitoring adult patients with EoE in Sweden.

use after also being checked by linguists. The validity analysis of the scale for the data collected was performed with exploratory factor analysis and item-total correlation tests, while the property of reliability was determined using the Cronbach’s alpha internal consistency coefficient and the stability test was carried out by determining the relationship between two applications conducted at an interval of the five weeks. The scale, which is called the “Scale for Determining the Civic-Mindedness Levels of Individuals” is a five-step Likert-type scale and consists of 27 items that can be collected under three factors. The factor names are “Openness to Criticism/Development”, “Participation/Activeness” and “Lack of Prejudice/Flexibility”. The KMO value of the scale was 0.956; and the Bartlett Test values were x2=11001.719; sd=351; p<0.000. Items in the scale accounted for 56.619% of the total variance. As a result of the confirmatory factor analysis, the χ2 value was 808.07 and the degree of freedom was 321. Χ2/df is 2.51. The fit indices of the scale were determined as RMSEA=0.067; S-RMR=0.049; NFI=0.97. The item-total corrected correlation coefficients of the items in the scale varied between 0.40 and 0.703 (p<.01). The reliability coefficient of the scale was Cronbach’s alpha at 0.954 and the stability coefficients of the items were between 0.496 and 0.674 (p<,01).

Background and objectives: Radiation accidents can cause numerous challenges to hospitals, the appropriate medical responses to which may save the lives of countless people. The present study aimed at the design and validation of an Emergency Department preparedness questionnaire for hospital emergency departments (EDs) in the case of radiation accidents, nuclear accidents, and nuclear terrorism in Iran.Materials and methods: This multistage cross-sectional study was conducted in 2019. The questionnaire items were created with the reference to article reviews and expert judgement. The validity of the questionnaire was assessed through face, content, and construct validities. Additionally, its reliability was estimated using measures of internal consistency and stability, namely Cronbach’s alpha and intraclass correlation coefficient (ICC). To this end, the questionnaire was completed by the ED staff in the hospitals of Iran.Results: The proposed 48-item questionnaire consisted of three themes: staff preparedness, stuff preparedness, and structure preparedness. The face and content validities were confirmed by expert judgement. All items remained with content validity ratio (CVR) 0.7 and the mean content validity index (CVI) = 0.891. The overall Cronbach’s alpha and ICC were 0.781 and 0.709, respectively for the whole questionnaire.Conclusion: Hospital ED preparedness in radiation and nuclear accidents requires readiness of staff, stuff, and structure of the ED, the consideration of which will properly respond to radiation and nuclear accidents. Thus, upstream organizations like the Ministry of Health and the Emergency Organization should oblige hospital EDs to make themselves be more prepared by codifying certain imperative laws and policies.

The objective is to validate the content of the information collection instrument, through expert judgement and pilot testing. Methodology: Non-experimental, correlational research with a cross-sectional design. The first sample of the expert judgment was composed of 8 experts, the second of 27 employees was used for the pilot test. Unit of measurement: Employees from four Technological Universities of Puebla, studying empowerment, leadership, work routine, collaborative work and innovation. The methodology of the analysis included the Kendall Concordance Coefficient (W), to decide the level of correlation between the experts and we used Cronbach’s Alpha for the statistical analysis of the pilot test to measure the reliability of the measurement scale. The results of the expert judgement showed changes that would improve the clarity of the instrument. The wording would be expressed in third person, the use of technical language would be avoided, with the aim of generalizing understanding in the wording. The identification data would be defined according to the organizational structure of the media unit. Kendall's coefficient and Cronbach's Alpha showed acceptable agreement. Discussion. It is important to control the application of these tests with strict adherence to the methodology, minimizing human bias. It is concluded that the content validity represents an elemental tool to evidence the dominance and representativeness of the constructs. If the results are not reached, it is possible to repeat the process until acceptable values are reached. It is proposed to improve the instrument as a result of the experts' judgment and check the concordance between experts.

Background: A reliability generalization study of a questionnaire is necessary to provide higher-level evidence for its reliability. This has not been performed for the Victorian Institute of Sport Assessment–Achilles tendinopathy (VISA-A) questionnaire. The VISA-A has been a commonly used questionnaire to evaluate the symptoms of Achilles tendon disorders and their impact on physical activity, one of the most common disorders among athletes and sports persons (9%-40%). Furthermore, this questionnaire has been translated to several languages and due to its simplicity is one of the most widely used questionnaires for patients with this type of disorder. Therefore, we performed a reliability generalization study of the VISA-A using MEDLINE (through PubMed) and Scopus as data sources. Methods: We selected studies that analyzed the reliability of the VISA-A by evaluating Cronbach’s alpha, the intraclass correlation coefficient (ICC), and the Spearman correlation coefficients to compare VISA-A with similar scales. The data were analyzed using fixed- and random-effects models. We assessed sensitivity through the leave-one-out method. Quality analysis was performed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Results: Of a total of 263 studies (eliminating duplicates), 7 fulfilled inclusion criteria. The mean reliability was (1) Cronbach’s alpha, 0.75 (95% CI, 0.70-0.79); (2) ICC, 0.91 (95% CI, 0.82-0.96); (3) correlation coefficient with the Curwin and Stanish grading system, –0.82 (95% CI, −0.93 to −0.56); and (4) correlation coefficient with the Percy and Conochie classification, 0.91 (95% CI, 0.87-0.93). We were unable to perform the funnel plot analysis and estimate meta-regression models. The Spearman correlation coefficients for both comparative scales showed influential studies (sensitivity analysis). Conclusion: Internal consistency and reproducibility were found to be good, but the parallel-forms reliability could not be supported. Therefore, more scientific evidence is needed to generalize the reliability of the VISA-A. Level of Evidence: Level I, meta-analysis of literature.

Abstract Background Postpartum maternal functioning has the potential to affect the quality of interaction between mother and child. A proper assessment of maternal functioning requires a comprehensive and accurate tool. The objective of this study was to prepare a Persian version of the Barkin Index of Maternal Functioning (BIMF) and evaluate its psychometric properties in order to determine its applicability in Iranian mothers. Methods The BIMF was translated into Persian and then culturally adapted for Iranian women. After evaluating face and content validity, to perform factor analysis, a cross-sectional study was conducted using the Persian version of BIMF. The data was collected from two unique groups of 250 mothers (in all 500 mothers) who had infants 2 to 12-months old and who were selected using a two-stage cluster sampling method. Factor analysis, Pearson’s correlation, intra-class correlation coefficients (ICC), composite reliability (CR) and Cronbach’s alpha were employed in order to evaluate structural validity and reliability. Results Exploratory factor analysis resulted in a five-factor structure consisting of 20 items. Subsequently, confirmatory factor analysis (X 2/ df = 1.61, RMSEA = 0.050, GFI = 0.91, CFI = 0.91) confirmed that the Persian version had satisfactory goodness of fit. Reliability and internal consistency were confirmed with a CR of 0.77, an ICC of 0.87 and a Cronbach’s alpha of 0.81. Conclusions The findings indicated that the Persian version of the BIMF is a valid and reliable instrument for assessing maternal functioning among Iranian mothers.

Background:An accurate physical fitness survey could be useful in research and clinical care.Purpose:To estimate the validity and reliability of a Self-Reported Fitness (SRFit) survey; an instrument that estimates muscular fitness, flexibility, cardiovascular endurance, BMI, and body composition (BC) in adults ≥ 40 years of age.Methods:201 participants completed the SF-36 Physical Function Subscale, International Physical Activity Questionnaire (IPAQ), Older Adults’ Desire for Physical Competence Scale (Rejeski), the SRFit survey, and the Rikli and Jones Senior Fitness Test. BC, height and weight were measured. SRFit survey items described BC, BMI, and Senior Fitness Test movements. Correlations between the Senior Fitness Test and the SRFit survey assessed concurrent validity. Cronbach’s Alpha measured internal consistency within each SRFit domain. SRFit domain scores were compared with SF-36, IPAQ, and Rejeski survey scores to assess construct validity. Intraclass correlations evaluated test-retest reliability.Results:Correlations between SRFit and the Senior Fitness Test domains ranged from 0.35 to 0.79. Cronbach’s Alpha scores were .75 to .85. Correlations between SRFit and other survey scores were –0.23 to 0.72 and in the expected direction. Intraclass correlation coefficients were 0.79 to 0.93. All P-values were 0.001.Conclusion:Initial evaluation supports the SRFit survey’s validity and reliability.

Dental anxiety (DA) is defined as unreasonable apprehension toward dental procedures. About 4–20% of the worldwide adult population presents DA, with peaks of 30% in the younger population. Managing patients with dental anxiety and fear with a reliable and valid instrument is necessary to understand the multidimensional dimensions of dental fear. This work aimed to validate the Index of Dental Anxiety and Fear (IDAF-4C+) into Italian. Two hundred and eighty dental students attending an Italian university were enrolled. The IDAF-4C+ was translated by experts and a native English translator, blinded to the original version. The Modified Dental Anxiety Scale (MDAS) was used to assess the validity of IDAF-4C+. Spearman correlation coefficients and Exploratory Factorial Analysis (EFA) were used. Reliability was evaluated by Cronbach’s alpha. The reliability of the Italian version of IDAF-4C+ was good (Cronbach’s alpha = 0.88). Correlation between IDAF-4C+ and MDAS ranged between 0.42 to 0.68. From EFA, one factor explained 58.76% of the common variance. Women showed a higher level of dental fear. The Italian IDAF-4C+ is a valid and reliable tool to assess DA in any clinical context. This instrument allows for a proper understanding and management of DA, and therefore a better patient oral health-related quality of life and compliance with the dentist’s instructions.

Limitations in hand function are common among children with cerebral palsy (CP), with almost 50% presenting an arm–hand dysfunction. However, there is no standardized assessment tool available in Italian for evaluating bimanual performance for this population. Our objective in this study was to evaluate the psychometric properties of an Italian translation of the ABILHAND-Kids (ABILHAND-Kids-IT) among children with CP. We examined internal consistency using Cronbach’s Alpha and Omega coefficients, and we investigated test-retest reliability with intraclass correlation coefficients (ICC). We performed explorative factor analysis (EFA) to investigate structural validity. We calculated Pearson’s correlation coefficients between the ABILAND-Kids IT and the Manual Ability Classification System (MACS) to assess criterion validity; and, to demonstrate the score variability of the ABILHAND-Kids-IT, we used analyses of variance (ANOVAs) to compare the 181 children with CP in this sample with their levels on the MACS. We enrolled 181 children with CP in the study. EFA confirmed a uni-dimensional scale. We obtained internal consistency on both Cronbach’s Alpha and Omega coefficient of 0.98, and a one-week test-retest reliability analysis revealed an ICC with 95% of confidence interval of .992. The ANOVA revealed significant score variability ( p < 0.01) and the Pearson correlation coefficient comparing the ABILHAND-Kids-It score with the MACS was –0.929 ( p < 0.01). We conclude that the ABILHAND-Kids-IT is valid and reliable for use with Italian children with CP.
