of work attitudes in the group aged 11-13 years was still high.
Interrater and Intrarater Reliability
. The weighted Ks with 95 percent CIs for all tested comparisons between internal reviewers and between external reviewers are depicted in Figure 2.
The data provided for the intrarater reliability
check suggest good test-retest reliability for the FAPRS.
Homburg (1984) found two problems associated with interrater and intrarater reliability
and reported that different raters often assigned the same composition to different grading categories, which may affect interrater reliability; and the same raters may assign the same composition to different grading categories at different times, which may affect intrarater reliability
The high intrarater reliability
(r = 0.9999, 12 [is less than] 0.01) and the low mean percent error (10%) indicated that the subjects' responses were reliable and consistent.
The ATRS has been demonstrated to have good intrarater reliability
, concurrent validity (Zentall & Barack, 1979), and predictive validity with both bottom movements and verbalizations (Zentall, Gohs, & Culatta, 1983).
To test the system's interrater and intrarater reliability
, data were coded from typed manuscripts of six audio-taped marital therapy sessions.
Interrater and intrarater reliability
refers to how consistent ratings of a tool are between different raters or between the same rater at different time points (Waltz et al., 2010).
Intraclass correlation coefficients (ICCs) were calculated for inter- and intrarater reliability
of volumetric measures to differentiate between random and fixed errors, using respectively the ICC(3,1) and ICC(1,1) equations , with a 95 percent confidence interval (CI).
The hallmark of a clinically useful test includes acceptable psychometric qualities related to the inter- and intrarater reliability
of the measure [9, 13].
To improve the internal consistency or intrarater reliability
all tests were taken two times (Spearman Brown formula).
Thus, the aim of this study was to assess both inter- and intrarater reliability
of the measurements of KPG index taken on images obtained with different CBCT scanners and analyzed with different 3D visualization software.
