one of the first internship projects I ever did was a Rasch analysis. It’s really just a statistical framework for refining questionnaires. I found that it’s primarily helpful for a few things...
it does not in any way ensure that your questionnaire assesses what you intended it to assess. Or that the results of the survey will actually be meaningful and useful, for that matter
@jnmaciuch if I understood right, its not sacrosanct magic surety, its a statistical
restructuring device to perfect draft questionnaires by Rasch analysis, flag up dual interpretation, prune query lists, grade severity of phases: but guarantees nothing.
I guess it can be used in algorithms which focus tools to screen, assess, classify, profile, grade, alert, warn, prevent, protect, demograph, survey and monitor people who all serve and are served at cost. Time and motion study got very advanced too
Can it query analysis of the objective technical measurements, still being replaced by triumphant behaviour analysts, in their comfort zones, way beyond the edge of feasible rehab?

Under Medical Devices Regulations, ethical approval is required
Ethical approval is required for a clinical investigation, undertaken by or with the support of the manufacturer, in order to:
- demonstrate the safety and performance of:
* a non-marked medical device
* a marked device that has been modified
* a marked medical device to be used for a new purpose" (e.g re-re-purposed Tyson must must re-re-re-cycle)
Can market registration of the Tysons' clinical software tool get approved on the basis of an investigation - by patient survey - gaining ethical approval?
Was it the filed and accessible Tyson application ..., or an accessible Tysons'
Rehab Academy (Evidence-Based) application, or accessible MEA applications supported by the manufacturer (a Tyson, the Tysons, or their Academy).
Why not keep us instruments informed
