Our objective was to create a large database of previously validated items that would serve as a starting point for the development of several item banks.
Item reduction for the development of the short version of the PGWBI was started from the reference data set achieved during the year 2000 when the original (long) questionnaire was administered for the first time in Italy to a representative sample of the general population (development sample).
North Korea sent 40 items to Assad for the development of ballistic missiles and chemical weapons over a five-year period, according to a leaked UN report.
In many ways, PIAAC represented the culmination of all that was learned over the several preceding decades in terms of instrument design, translation and adaptation procedures, scoring of open-ended items, and the development of interpretive schemes for large-scale assessments.
An exploratory factor analysis was initially conducted, with the aim of determining which latent variables (items) could be significant for the development of the model and the hypotheses testing.
Parental self-efficacy is measured by the 15 efficacy-focused items of the Screener for the Development of a Response Posttrauma (SDRP).
The initially calibrated item bank that was used for the development of the CAT Fatigue RA consisted of 196 items and 3 dimensions, which included all 12 dimensions that emerged from the Delphi study.
This included the definition and operationalization of individual facets (sub-categories) and facets (main categories) of quality of life, the formulation and choice of questionnaire items, the development of response scales for single item groups and the field testing of the instrument by conducting pilot studies [ 12, 18].
This aimed at identifying a potentially imbalanced distribution of item difficulties, allowing the development of further items for respective difficulty levels.
