Psychometric properties of the Care Dependency Scale in stroke survivors in Indonesian hospitals.
Nursiswati Nursiswati, Ruud J G Halfens, Christa Lohrmann
PMID 32817856WHAT IT FOUND
Nurses using the Indonesian CDS rated stroke survivors' care dependency consistently in inpatient and outpatient settings.
The scale did not closely match the Barthel Index, so use it as a nursing assessment, not as a replacement for functional measures.
Key findings
01The 15 CDS items scored very consistently as a set (Cronbach's alpha 0.98) in both inpatient and outpatient settings.
02For the outpatient total score, agreement between two nurses was 0.60 by kappa and 0.75 by intraclass correlation.
03In 49 participants who also had Barthel Index ratings, the CDS and Barthel Index scores correlated 0.54.

What it does not show
The analysed sample was 109 stroke survivors, and only 49 had Barthel Index data, so the concurrent validity analysis was limited. The study did not test construct validity with factor analysis. In outpatient data, 16.51% of rating score differences were more than 15 points, and the three largest differences were 33, 38 and 59. The outpatient total-score agreement was kappa 0.60 and intraclass correlation 0.75. The scale was tested only in the Indonesian version among stroke survivors in four Indonesian hospitals. Time limitations may have prevented nurses from using both the CDS and Barthel Index, as only 49 of 109 participants had Barthel Index data.

The easy way to misread this
Do not read this as evidence that using the CDS improves stroke care. The study tested how consistently nurses scored 109 stroke survivors, not whether using the scale changed care outcomes.
