The next step is psychometric validation of these item pools.
Though this omission may represent an incomplete validation of these items, the strong results in the other attack categories indicate that the transport section of the instrument, with similar answer fields, is reliable.
Initial validation of the item-reduced PPAC instruments comprised reliability (internal consistency and test retest reliability) and construct validity (convergent, known-groups and discriminant validity) [ 23, 27].
In addition, the panel urged that the NCDB undertake a validation of those items reported to the NCDB that are not collected by state or regional registries (e.g., insurance status, secondary diagnoses used to gage comorbid disease status, and disease recurrence) that might otherwise be subject to routine quality control by central registries.
Therefore, the two objectives of this paper are to present the development and validation of an item pool to measure mobility in older people and to analyse differential item and bundle functioning across gender.
Due to the scarcity and importance of late life mobility measures, the first of the two objectives of this paper is to present the development and validation of an item bank to measure mobility in community dwelling older people, using IRT methods.
During the design and validation of an item bank to measure mobility in older people, we found that strength (carrying, lifting and pushing) items formed a secondary dimension that produced DBF.
There were no mismatches in the cross-validation of the items after they were back-translated; see Table 1.
This study reports the development and validation of the 20 item Family Food Behavior Survey, a measure designed to assess broad components of the family food environment that may contribute to child overweight.
In this paper, we present the development and validation of a mobility item pool in a sample of 593 older people attending primary health care practices in Spain.
Importantly, in our reporting of the development, content, and validation of the single item SMS depression rating scale, we place this instrument (the R-SMS-DS) in the public domain to be used freely, conditional only upon appropriate acknowledgement of authorship in any published work.
