Obtained results show that the use of different instruments consistent with ISO Standard 7726 requirements results in values of the mean radiant temperature compatible with each other, but the consequences on thermal environment assessment appear often ambiguous.
Several other instruments consistent with our theoretical model were used.
All biopsies from an individual patient at a given time point were obtained with the same surgical or endoscopic instruments, consistent with previously published protocols [ 3, 5, 13- 15] but leading to the possibility of cross-contamination.
Chronic pain was associated with the highest clinically important difference in HRQL using both versions of the EQ-5D instrument, consistent with previous findings [ 3, 20, 21].
After data collection was complete, we assessed the dimensionality, reliability, and validity of the survey instrument, consistent with Benson's (1998) structural and external stages of development.
The findings from the CFA have furnished compelling support of the HADS as a tri-dimensional instrument, consistent with contemporary research with this instrument across diverse clinical presentations [ 19, 26, 30, 31, 33, 35].
COSMIN stipulates that construct validity is the degree to which the scores of health related outcome instruments are consistent with hypotheses formulated prior to data analysis, based on the assumption that the instrument measures the construct of interest [ 27].
Differences between instruments are consistent with the SD of the change score, which is smaller in the Item-Improved and IRT-based scales.
Uher et al, using a large sample, found that self-reporting instruments are consistent with clinician-rated methods, and so may be used interchangeably; however, the participants in that study were not elderly.
This distinction between the two instruments is consistent with previous research indicating that condition-specific patient-reported outcome measures tend to be more responsive to change than generic measures [ 36- 38].
The researchers kept in mind all previous suggestions and ensured the instrument was consistent with the original instrument [ 14].
