The «well - established» measures are supported by peer -
reviewed psychometric data.
Not exact matches
Due to post equating and
psychometric reviews on assessment
data, quick scores might look different from final accountability results.
In summary, the reliability and validity
data reported for the measures examined in this
review are quite impressive, with two exceptions: (a) the quality of the
psychometric data is poor for the subscales of some measures, and (b) there is little concurrent or predictive validity for most measures of perceived self - concept and self - esteem.
As noted earlier, 34 of the 37 measures
reviewed met «well - established» criteria, but most of these 34 measures also have at least one major
psychometric problem or lack certain types of
psychometric data.
Two reviewers will independently assess the suitability of the preference - based instruments for measuring outcomes in palliative care using the ISOQOL, minimum standards for patient - reported outcome measures (conceptual and measurement model, reliability, content validity, construct validity, responsiveness, interpretability of scores, translation of measure, patient and investigator burden), 43 and the CREATE checklist (descriptive system, health states values, sampling, preference
data collection, study sample, modelling, scoring algorithm).44 The ISOQOL minimum standards were chosen as these standards were developed from a systematic
review of published and unpublished guidance on patient - reported outcome measures, including the COnsensus - based Standards for the selection of health Measurement Instruments (COSMIN).46 To the authors» knowledge, the CREATE checklist is the only published guidance on what key components should be reported in a valuation study.44 Information on how the contents of the instruments were developed,
psychometric properties and valuation will be used to assess the suitability of the instruments for the palliative setting; instruments will be scored on whether the domains or dimensions were developed using input from informal caregivers of people receiving palliative care (yes / no) and whether each of the reporting checklist items has been evaluated for this population (if yes, then a score of one will be allocated) and a total score calculated.
The reported
psychometric properties are excellent, and
data derived from the coding scheme have been presented in multiple peer -
reviewed papers, however, only by one investigatory team, placing the measure in the «approaching well - established» category.
For classification purposes, we only considered
psychometric data reported in empirical, peer -
reviewed manuscripts, though our
reviews include
data from nonpeer
reviewed manuals, chapters, and peer -
reviewed reviews.
When multiple peer -
reviewed manuscripts provided
psychometric data for a given instrument, the preponderance of the evidence needed to be consistent with our definition of «good» for a measure to qualify as «well - established.»
