Quick reminder:
"Content validity is defined as the degree to which the content of a measurement instrument adequately reflects the outcome being measured. [...] It is considered to be the most important measurement property".

The last annual update I will be involved in... 😅👋


Screenshot of the intro of the ISOQOL news item, with the following text: News from “Quality of Life Research” Nov 21, 2024 Jan R. Boehnke, PhD, Brittany Lapin, PhD MPH, and Jessica Roydhouse, PhD Quality of Life Research Co-Editors-in-Chief The Co-Editors in Chief of Quality of Life Research (QLR) would like to thank ISOQOL and its members for their support in 2023. We received 1,903 submissions and accepted 247 articles. The journal’s editorial board managed high workloads and helped us identify relevant content for the community of (health-related) quality of life researchers. Importantly, 727 unique reviewers contributed at least one review, supporting the high quality of our content.

@TomJewell

I argue that there is some understanding in the and professional communities that use that evidence of quality is tentative as any statistical result.

And in my personal view, the different methodologies has developed (e.g., link.springer.com/article/10.1) or is currently pushing forward (doi.org/10.1186/s13643-022-019) are tools to aggregate available evidence exactly for this reason: each individual study and estimate offers an incomplete picture.

Translations of questionnaires are difficult. Consider using the guidelines by the International Testing Commission to plan your study:

Use participatory methods to (i) identify which instrument is relevant to translate; and (ii) to develop a population-appropriate translation.

And helps to identify which type of evidence is needed:

Opened by a of instruments measuring the quality of dying and death in Asian countries:

the issue features several pieces on properties of various instruments in different contexts and versions, e.g.,

@flourn0
I have been myself inconsistent in this and cannot offer anything directly in the remit of your question, but eg. the 2nd supplement of this could be made a usual addition to any paper, testing invariance of measures in a given application:
royalsocietypublishing.org/doi

That would allow researchers planning for their projects or interested in psychometric properties at least to collate relevant information on such aspects.
