For a given vignette, items are regrouped by formats (e.g. some items on diagnosis, followed by some items on investigation).
Ten items were regrouped based on Donabedian's framework to cover interpersonal relationships (three items), and structure in the form of organization, material and human resources (seven items).
These items were regrouped into two distinct sections: 1) medical discharge summary and 2) discharge prescription.
Also, since no overall scores are calculated in the interRAI method, the items are regrouped into clinical assessment protocols (CAPs) and scales defined by interRAI.
CFA models were iteratively trimmed by dropping items that were not explained well by the model and regrouping items when less than three items were left in a factor/domain.
Considering previous experience with the questionnaire [ 15, 26], the 38 items of the NHP38 were regrouped into two new, different scales before Rasch analysis was performed: a Physical scale (containing Energy, Pain and Physical Mobility dimensions) – 19 items – and a Psychological scale (containing Emotional Reactions, Sleep and Social Isolation) – 19 items.
The 29 activities or items in this table can be regrouped into three broader groups: The first group is made up of activities for which fewer than 10% of people required supervision or assistance (15/29 items).
Nevertheless, the findings from the studies of exploratory factor analysis performed on healthy samples showed the subscales possess unimportant items or some that could be regrouped differently, suggesting revisions for the KINDL [ 8, 10, 13].
These were therefore regrouped with the group 1 items.
When disregarding previous partitioning and exposing all items to exploratory scale partitioning, they risk being regrouped in ways that were not initially intended.
