2025
This paper outlines the protocol for qualitatively and quantitatively validating a university service-learning instrument, following the parsimony criterion to create the most robust and optimal version possible. The Delphi qualitative validation method and Robust Unweighted Least Squares Exploratory Factor Analysis, as a quantitative item optimization method, are utilized for this purpose.

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

2026
Here, we present a protocol to semi-quantitatively assess global m⁶A levels using dot blot. Total RNA is extracted, denatured, spotted on a nylon membrane, probed with anti-m⁶A antibody, and visualized by chemiluminescence. Signal intensity, quantified by ImageJ grayscale analysis, reflects relative methylation abundance, providing a reproducible workflow for research.
FAQs
Reviewers reach a GQS score by considering several qualities together rather than judging a single feature in isolation. Reliability addresses whether the information can be trusted, while flow concerns how clearly ideas are organized. Accessibility and practical usefulness indicate whether the material can be understood and used effectively by its intended audience.
Reliable information may still provide limited value if its organization makes the content difficult to follow or its presentation reduces accessibility. By considering flow and accessibility alongside reliability, the GQS captures both informational quality and communication effectiveness. This broader judgment is particularly relevant when assessing medical resources intended for patient education.
The score signals how well a medical resource combines trustworthy content, clear organization, accessibility, and practical usefulness. A lower result points to limited overall value, whereas a higher result indicates stronger quality and usefulness. This interpretation helps reviewers distinguish resources that may need substantial improvement from those that communicate health information effectively.
A reviewer examines the resource as a whole, considering its reliability, flow, accessibility, and usefulness before assigning a score from 1 to 5. The reviewer then records the overall judgment consistently across materials. Applying the same scale to each resource creates a structured basis for evaluating and comparing medical information.
The GQS can be applied to patient education materials, websites, and other digital health resources. Its use across these formats supports assessment of how effectively medical information is presented and whether it offers practical value. This makes the scale relevant to studies examining the quality of information encountered through online and educational channels.
Researchers can use the common five-point scoring framework to compare the overall quality and usefulness of multiple medical resources. Because each item receives an assessment based on reliability, flow, accessibility, and practical value, differences between resources become easier to identify. The resulting comparisons can reveal variation in health information quality across materials.
GQS results can highlight communication gaps within patient education materials, websites, or digital resources. A lower overall assessment indicates that the resource may need improvement in reliability, organization, accessibility, usefulness, or a combination of these areas. Reviewing such patterns helps guide efforts to strengthen evidence-based health communication and improve the value of medical content.
