Using the instrument, we studied how critical thinking skills differ among 3rd grade students, according to their socioeconomic status (SES), studying schools with low, middle and high SES.
Like the original mini-CEX and similar assessment instruments [ 14], the instrument we studied is designed to generate feedback on observed performance during a clinical encounter.
By using several quality of life instruments, we have studied GERD patients more comprehensively than previous studies [ 31, 32, 35]; however, our results are confined to GERD patients with moderate to severe symptoms who were participating in a clinical study.
We studied six instruments: the (1) Legacy HAQ and (2) PF-10, (3) Item-Improved HAQ and (4) Item-Improved PF-10, and the (5) PROMIS PF-10 and (6) PROMIS PF-20.
To assess the capability of the RLS instrument under Martian environmental conditions, we studied the Raman spectra of calcite, aragonite and baryte inside the MASC at different temperatures and pressures.
As the course of RA may extend to more than 60 years, no study can encompass the duration of the illness, and many of the study instruments we used have been in common use for less than 25 years [ 28, 29].
We included both instruments that studied satisfaction of a broad set of needs derived from a health status perspective, and instruments that studied one class of needs only, e.g., needs for information or for one type of cancer.
For the rationale behind these instruments, we refer to the study of van Otterloo et al. (2006).
In addition since we could not find well-validated Iranian version of instruments we needed for this study, most of the information has been collected through questionnaires developed by the authors.
