Deans' stroke musings: Cross-validation of the factorial validity of the stroke impact scale 3.0 in patients with stroke

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Cross-validation of the factorial validity of the stroke impact scale 3.0 in patients with stroke

You can check it out here. Stroke Impact Scale 3.0

To me this is totally wrong way to measure it. It is a binary question. ARE YOU 100% RECOVERED? YES/NO?

Abstract:

Study examined the underlying structure of the Stroke Impact Scale 3.0 (SIS-3.0), a promising outcome measure of health-related quality of life (HRQOL) for clients with stroke, by comparing the currently available eight- and four-domain structures simultaneously. This was a secondary data analysis of responses to the SIS-3.0 from a previous psychometric validation study. In that study, 263 patients with stroke were recruited from the rehabilitation wards (inpatients) and neurology and rehabilitation clinics (outpatients) of five general hospitals in northern and southern Taiwan. Confirmatory factor analysis was used to examine the eight- and four-domain structures of the SIS-3.0. Four fit indices were considered simultaneously to examine the model fits of both structures: (1) chi-squared value adjusted for model complexity, (2) comparative fit index, (3) root mean square (RMS) error of approximation, and (4) standardized RMS residual. The eight- and four-domain structures of the SIS-3.0 were not supported by all four indices. The unidimensionality of each domain in the two structures was not supported. Neither the eight- nor the four-domain structure of the SIS-3.0 was supported, suggesting that scores may not provide valid assessments of HRQOL in clients with stroke. Further modification and validation of the SIS-3.0 are warranted. These findings suggest that the eight- and four-domain scores of the SIS-3.0 may not be valid. Therefore, until more supporting evidence is developed, these scores should be interpreted cautiously regarding clients’ HRQOL; alternatively, other measures could be used.
