Validation of the Perception of eHealth Technology Scale in Chinese Brief (PETS-C Brief) in Nurses: Survey Study

Validation of the Perception of eHealth Technology Scale in Chinese Brief (PETS-C Brief) in Nurses: Survey Study

Our validation study supported the four-factor structure of PETS-C Brief with satisfactory validity and reliability in Chinese nurses. The results of CFA showed a four-factor structure. Though the χ2 test was statistically significant, this has been common in large samples [32].

A Serious Game (Health Unit in Focus) for Enhancing Undergraduate Education on Older Adults’ Health: Design and Validation Study

A Serious Game (Health Unit in Focus) for Enhancing Undergraduate Education on Older Adults’ Health: Design and Validation Study

Figure 1 [13] describes the stages of the game’s development, testing, and validation. Stages of game construction (adapted from Jaffe [13]). In stage 1, the game’s objectives, educational aims, content, and problematizations were established. For stage 2, the context in which students would use the theme was surveyed. In stage 3, the competitive aspects were adjusted to the application’s proposal, as it is a single-player game.

Development and Validation of a Questionnaire to Measure Digital Maturity of General Practitioner Practices: Web-Based Cross-Sectional Survey Study

Development and Validation of a Questionnaire to Measure Digital Maturity of General Practitioner Practices: Web-Based Cross-Sectional Survey Study

This requires the empirical validation of both dimensions and items, a step that is often criticized as missing in the development of maturity models [18]. Currently, however, such validation is absent from the few existing scientific publications on measuring digital maturity in GP practices [19-22]. Instead, frameworks or dimensions from other areas of health care are often applied.

Validity of Heart Rate Measurement Using Wearable Devices During Cardiopulmonary Exercise Testing in Patients With Cardiovascular Disease: Prospective Pilot Validation Study

Validity of Heart Rate Measurement Using Wearable Devices During Cardiopulmonary Exercise Testing in Patients With Cardiovascular Disease: Prospective Pilot Validation Study

A recent validation study [12] reported that HR measurements using the Apple Watch 7 (Apple Inc) and Galaxy Watch 4 (Samsung Electronics Co, Ltd) during cardiopulmonary exercise testing (CPX) were highly accurate in patients with CAD, indicating their potential utility in this population. However, these devices are relatively expensive (approximately US $350), and their accessibility to individuals with low income, who may already be reluctant to participate in outpatient CR, remains limited [4].

The Validation and Accuracy of Wearable Heart Rate Trackers in Children With Heart Disease: Prospective Cohort Study

The Validation and Accuracy of Wearable Heart Rate Trackers in Children With Heart Disease: Prospective Cohort Study

Validation is performed in a cohort of children with congenital heart disease (CHD) or (suspected) arrhythmias, during a 24-hour free-living period, in comparison with the gold standard Holter ECG. In addition, this study aims to explore factors that influence measurement accuracy, such as bodily movement, and evaluates patient comfort and satisfaction with the wearables during the 24-hour measuring period.

Label Accuracy in Electronic Health Records and Its Impact on Machine Learning Models for Early Prediction of Gestational Diabetes: 3-Step Retrospective Validation Study

Label Accuracy in Electronic Health Records and Its Impact on Machine Learning Models for Early Prediction of Gestational Diabetes: 3-Step Retrospective Validation Study

Several studies have used EHRs to build ML models predicting the likelihood of developing GDM later in pregnancy [15], but none have described validation of the GDM “label” within the EHRs.

They typically involve validation procedures (eg, training models on a subset of data and validating its performance on an unseen subset; see section “Testing, Validation, Cross-Validation, and External Validation”), enabling robust prediction of new or future outcomes across individuals or within individuals over time [11].

An AI-Based Telerehabilitation Solution to Improve Mobility in People With Multiple Sclerosis (the PLATINUMS Project): Protocol for an Implementation and Evaluation Study

An AI-Based Telerehabilitation Solution to Improve Mobility in People With Multiple Sclerosis (the PLATINUMS Project): Protocol for an Implementation and Evaluation Study

WP3 (validation of remote mobility measures) is scheduled to launch in September 2025, and the multicenter RCT (WP4) is planned to begin in January 2026. Project coordination and dissemination activities (WP7) have been ongoing since March 2025. Initial findings from WP2 are expected to be available by October 2025, with preliminary publications planned for mid-2026.

Quality of Life Among Family Caregivers of Individuals With Rare Diseases: Web-Based Population Study on the Validity and Reliability of the Polish World Health Organization Quality of Life-BREF Questionnaire

Quality of Life Among Family Caregivers of Individuals With Rare Diseases: Web-Based Population Study on the Validity and Reliability of the Polish World Health Organization Quality of Life-BREF Questionnaire

However, this validation process overlooked caregivers, an essential yet often neglected population in HRQo L research. Caregivers play a vital role in the health care system, providing continuous support to individuals with chronic illnesses and disabilities. Despite their crucial contributions, caregivers often experience significant physical, emotional, and financial burdens, which in turn affect their own Qo L [10-13]. Caregivers of persons with RDs face particularly severe challenges.

Facial Emotion Recognition of 16 Distinct Emotions From Smartphone Videos: Comparative Study of Machine Learning and Human Performance

Facial Emotion Recognition of 16 Distinct Emotions From Smartphone Videos: Comparative Study of Machine Learning and Human Performance

The test set used for the validation of the newly developed models was taken from the STREs Wo Z dataset and comprised 13 individuals displaying 1 of the 16 emotions. All individuals were women, with a mean age of 20.92 (SD 2.06; range 18-24) years, White, and—except for 1—reported elevated subjective stress levels. The test set included 3018 videos. For the validation with human observers, they were not only shown the emotional phase but the entire videos.
