An Image-Voice Dietary Assessment System for Estimating Individual Nutrient Intakes in Cambodian Women and Children: Relative Validity, Reliability, and Acceptability Study

An Image-Voice Dietary Assessment System for Estimating Individual Nutrient Intakes in Cambodian Women and Children: Relative Validity, Reliability, and Acceptability Study

We aimed to describe a new dietary assessment system, the Voice-Image Solution for Individual Dietary Assessment (VISIDA), and to evaluate its relative validity in comparison to 24-hour recalls, as well as its test-retest reliability and acceptability, among Cambodian women and children aged ≤5 years. This study was a free-living, observational design, with data collected between August 2019 and March 2020 in Siem Reap province, Cambodia.

Ecological Momentary Assessment as a Measure of Intervention Change: Evaluation in 4 Digital Mental Health Trials

Ecological Momentary Assessment as a Measure of Intervention Change: Evaluation in 4 Digital Mental Health Trials

Next, to compute the reliability of residualized change in retrospective rumination, we used the following formula, which has the reliability of retrospective rumination scores at T1 (αT1) and T2 (αT1) and the squared correlation coefficient () between these 2 scores [73] as inputs: It should be noted that the reliability of residualized change (Z) will increase if the reliability of either T1 or T2 rumination scores increases or if the correlation between T1 and T2 rumination decreases (see Multimedia Appendix

Development of the SCI-BodyMap—Measuring Mental Body Representations in Adults With Spinal Cord Injury: Protocol for Item Generation, Reliability, and Validity Testing

Development of the SCI-BodyMap—Measuring Mental Body Representations in Adults With Spinal Cord Injury: Protocol for Item Generation, Reliability, and Validity Testing

In addition, psychometric assessment, such as interrater reliability, test-retest reliability, feasibility, utility, face validity, concurrent validity, and other relevant analyses, is important before using the scale in the clinic or for research. Therefore, our overall aim is to develop an MBR assessment for individuals with SCI (ie, the SCI-Body Map) and to assess its psychometric properties.

Extracting Clinical Guideline Information Using Two Large Language Models: Evaluation Study

Extracting Clinical Guideline Information Using Two Large Language Models: Evaluation Study

Our objective is to enhance the clinical applicability and reliability of medical information while improving the dissemination of PGx knowledge. This methodological study followed the enhanced Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis (TRIPOD)-LLM reporting guidelines [9]. This study did not involve human participants, identifiable personal data, or biological materials.

Validation and Acceptability of the Mobile App Version of the Control of Allergic Rhinitis and Asthma Test for Children (CARATKids): Cross-Sectional Study

Validation and Acceptability of the Mobile App Version of the Control of Allergic Rhinitis and Asthma Test for Children (CARATKids): Cross-Sectional Study

The relative reliability between the two versions was determined using the intraclass correlation coefficient (ICC), using both two-way mixed single measures, while the absolute reliability was evaluated through Bland-Altman plots. Convergent validity between the traditional paper-based version and the mobile app version of CARATKids was assessed through Spearman rank correlation coefficient.

Proposal for Using AI to Assess Clinical Data Integrity and Generate Metadata: Algorithm Development and Validation

Proposal for Using AI to Assess Clinical Data Integrity and Generate Metadata: Algorithm Development and Validation

The goal of this paper is to demonstrate the varying quality of medical data in primary clinical source systems and to inform researchers about data reliability using machine learning techniques. This approach seeks to identify predictive model-based quality algorithms for clinical data, including RWD, to facilitate automated quality inspection, ensuring data completeness and consistency.

A Novel Framework to Assess Clinical Information in Digital Health Technologies: Cross-Sectional Survey Study

A Novel Framework to Assess Clinical Information in Digital Health Technologies: Cross-Sectional Survey Study

However, these approaches addressed only the content and face validity of the CLIQ framework and not its applicability, reliability, and construct validity. Therefore, the aim of this study is to assess the applicability, internal consistency, and construct validity of the CLIQ framework.

Validation of Gait Kinematics With Ramp and Stair Ascent and Descent Revealed by Markerless Motion Capture in Simulated Living Space: Test-Retest Reliability Study

Validation of Gait Kinematics With Ramp and Stair Ascent and Descent Revealed by Markerless Motion Capture in Simulated Living Space: Test-Retest Reliability Study

Therefore, it is clinically important to investigate the application and reliability of Theia3 D for these activities. While previous studies have validated Theia3 D for level walking, its reliability in assessing more complex movements in a simulated living environment remains unclear due to the increased variability and dynamic adaptations required for tasks such as stair and ramp walking.

Translation, Cross-Cultural Adaptation, and Psychometric Validation of the Health Information Technology Usability Evaluation Scale in China: Instrument Validation Study

Translation, Cross-Cultural Adaptation, and Psychometric Validation of the Health Information Technology Usability Evaluation Scale in China: Instrument Validation Study

The questionnaire had satisfactory reliability and validity, with the scale-content validity index (S-CVI), Cronbach α coefficient, and split-half reliability of 0.97, 0.96, and 0.99, respectively [25]. Given its focus on users of medical apps, the questionnaire was only administered to older people.
