Prevalence of any BF/PTG was defined as checking more than the lowest item score ('not at all') at least once.
(2013), (hat{f}_{jk}(1|varvec{theta })) can be considered as an estimated unconditional expectation of the item score at (varvec{theta }) and (bar{f}_{jk} y|varvec{theta })) can be considered as an estimated conditional expectation of the item score at (varvec{theta }), conditional on the data.
The mean item score at T1 was 0.09 (SD = 0.18, range 0 1.7) for the CBCL-ACD scale and 0.14 (SD = 0.22, range 0 1.5) for the YSR-ACD scale.
At T2 the mean item score was 0.05 (SD = 0.13, range 0 1.5) for the CBCL-ACD scale and 0.13 (SD = 0.19, range 0 1.8) for the YSR-ACD scale.
At T2 the mean item score was 0.42 (SD = 0.39, range 0 2) for the CBCL-scale and 0.45 (SD = 0.35, range 0 2) for the YSR scale.
The vertical lines of varying length on the ICC are error bars that indicate the estimated 95% point-wise confidence limits for the value of the curve (item score) at a specified disability level (standard normal score).
For example, among the 119 patients currently in continuing care and receiving methylphenidate (Table 4), their mean (SD) total ADHD-RS-IV item score at baseline was 2.5 (0.4), and none had a mean item score of ≤1, indicating a severely impaired population (see Table 2 for clinical interpretation of scores).
Although the unidimensional nature of the scale may reduce the ability to discern which areas of functioning are affected, looking at individual item scores could provide additional information.
Figure 1 shows the proportion of patients who were affected by the individual barriers (assuming a barrier existed in case of an item score of at least 3).
At the most recent clinic visit, mean (SD) total ADHD-RS-IV item score remained low at 0.8 (0.8), although the average score across all post-titration continuing care visits was slightly higher (1.0 [0.6]).
