Psychometric Properties of the Korean Dispositional Hope Scale Using the Rasch Analysis in Stroke Patients.
Eun-Young Park, Yoo Im Choi, Jung-Hee Kim
PMID 31819741WHAT IT FOUND
The Korean Dispositional Hope Scale appeared suitable for community stroke patients who completed the scale.
Eight items and the response options worked well, but 38.6% of participants were outside the scale's usable range.
Key findings
01Eight items of the Korean Dispositional Hope Scale were judged appropriate by the study's item-fit criteria.
02The response scale showed no inappropriate functioning.
0338.6% of participants were outside the range covered by item difficulty, so the scale may not capture very high or very low hope well.

What it does not show
The study included only patients who scored more than 21 on the Korean Mini-Mental State Examination, so it does not show how the scale performs in stroke patients with significant cognitive deficits. The authors noted sample bias and self-reported bias may affect interpretation. 38.6% of participants were outside the item difficulty range, so the scale may not capture very high or very low hope well.
The easy way to misread this
Do not read the scale's good fit as proof it works for every stroke patient. The sample included only patients who scored more than 21 on a mental state test, and 38.6% of participants were outside the scale's usable range.
