The results in Figure 3 show high external validity of the model due to its ability to perform well with training on one hospital dataset and subsequent testing on the other hospital dataset.
Model performance of training exclusively on one hospital’s data and testing on the other’s data. (A) and (B) Performance of training on MGH data and testing on BIDMC data. (C) and (D) Performance of training on BIDMC data and testing on MGH data.

Future studies should be aware of this limitation and carefully review the reference data as well, as errors or artifacts in the reference measurements could lead to misleading comparisons and affect the validity of the findings. Fourth, while the wearing position and fitting of the devices were standardized to ensure consistency, it might not reflect real-world usage where users may wear devices loosely or incorrectly.

The I-CVI and the Scale CVI/Average (S-CVI/Ave) were used to evaluate content validity of the instrument. I-CVI≥0.78 and S-CVI/Ave≥0.90 indicate satisfactory content validity [24].

As such, in this study, we aimed to: (1) test the hypothesis that distinct CCP subgroups exhibit differential risks of cervical precancer or cancer based on their complex phenotypic profiles (development); (2) demonstrate internal validity (within a dataset and across methods), as well as external and diagnostic validity (across datasets; validation); and (3) propose a computational phenomapping strategy with clinical relevance and pathways to improve global access to CCP (impact).

The validity and reliability of 38-item STAM have been established on a satisfactory scale in 1012 older adults aged 55 years and older in Hong Kong [24]. The construct validity of the STAM was also evaluated with the confirmatory factor analysis (CFA) and revealed a satisfactory model fit with the proposed structure (comparative fit index [CFI]=0.938, root mean square error of approximation [RMSEA]=0.054, and standardized root mean square residual [SRMR]=0.075).

The hypothesis was that the software would demonstrate comparable accuracy and validity in heart rate measurement during a 6-minute walking test (6 MWT) and a 47-minute interval training session, matching the performance of a certified ECG, which is considered the gold standard.
The prospective interventional PROTEGO MAXIMA trial was designed to evaluate the validity, accuracy, and safety of a prehabilitation app.

Assessment of Reliability and Validity of Celiac Disease–Related YouTube Videos: Content Analysis
We could not find any studies in the literature that evaluated the reliability and validity of You Tube videos about CD. This study aims to evaluate the quality and reliability of You Tube videos about CD using validated scoring tools and detailed content analysis.
In this cross-sectional study, videos were collected using the keyword “Celiac Disease” in You Tube’s search engine on November 15, 2023.

RCT is a gold-standard method to evaluate the efficacy of treatments because they have the highest internal validity [6]. However, the external validity of trial evidence may be limited in the sense that their findings may not always be applicable to or generalizable to clinical populations or population characteristics [7]. This is because RCTs commonly exclude large proportions of patients treated in normal practice.

Considering its significant market prominence, it is crucial to rigorously assess the accuracy of the Huawei smartwatch in measuring health-related indices to ensure its validity for users’ health monitoring and lifestyle management. Clearly, researchers have long voiced out the need to regularly examine the accuracy of smartwatches in order to continuously improve their functions and better apply them to human health promotion.

Features related to game characteristics, rationale, functionality, validity, and data protection are the 5 main areas described in the framework [28]. The “classical” concepts of validity (content validity, face validity, construct validity, concurrent validity, and predictive validity) were included in the framework as they are most frequently used in validity research in medicine.
