Although this examination of the ALDS item bank has concentrated on six sets of items, future applications of the item bank are not bound to these sets of items.
This paper explored the feasibility and utility of a potentially novel application of item response theory.
This study asked whether the properties of medical codes in electronic patient records may be characterised through the application of item response theory models.
The application of item response theory models to coded electronic patient records might potentially contribute to identifying medical codes that offer poor discrimination or low calibration.
Development of such versions can be informed by the application of item response theory (IRT) models, which also provide a more detailed description of measurement precision and can provide data for interpretability of the ThyPRO.
This is a vigorous application of items 3 and 4 from Alston's inventory.
Second, application of item-response theory to the LLDI short form offered support for the content of the social subscale, but it was mixed for items making up the personal subscale.
Pushing or placing something inside the vagina (including powders, creams, herbs, tablets, sticks, stones, leaves, cotton, tampons, tissue etc).. [ 10] Menstrual practices are also examined in this paper, and include intravaginal cleansing to remove blood, intravaginal insertion or external genital application of items to collect blood, and sexual activities during menstruation.
One consequence of a relatively small sample size is that the person and item standard errors are larger than might be optimal for broader application of the item banks.
Scaling these variables usually requires application of an item response theory (IRT) model (Martin and Mullis 2012; OECD 2014b).
