Sentences with word «cutpoint»

Statistical cutpoints for domains have been set at the 90th percentile (Carter et al., 2003).

For example, one may set cutpoints at 1.5 or 2 standard deviations from the mean on each scale.

Moreover, the combined BITSEA problem / competence cutpoints identified 85 % of subclinical / clinical CBCL / 1.5 - 5 scores, while maintaining acceptable specificity (75 %).

It also is probable that a different proportion of children would be identified as positive using the statistically at - risk cutpoints developed in this study if the BITSEA were used to screen early intervention samples.

Statistical cutpoints for problems and competence were defined in 6 - month age groups by child's sex (Table I).

Discriminant validity was assessed by comparing BITSEA cutpoint status with MCDI vocabulary scores.

Unlike under NCLB, where districts focused on students right at the cusp of proficiency — the «bubble» kids — this sort of method creates several, more frequent cutpoints that make it harder to focus on just a small subset of students.

These methods do not preclude categorical taxa, which can be formed by imposing cutpoints on the distributions of syndrome scores.

The BITSEA was most sensitive to competence when both problem and competence cutpoints were used, a pattern that may reflect the inclusion in the BITSEA / P scale of atypical behaviors that may co-occur with delay, thus boosting sensitivity to delays in competence.

The distributions of the BITSEA scales were examined to determine whether statistically at - risk cutpoints should be defined based on child age and sex.

Thus, age by sex statistical cutpoints were indicated for competence.

For parous women, the p values for the interaction terms between age at diagnosis and duration of breastfeeding were 0.08 and 0.28 when trying models with the cutpoints < 40 years vs. older and < 56 years versus older, respectively.

Thus, there was not one natural «cutpoint» for waist circumference that could be used in the clinic, as risk increased across the spectrum of circumferences.

In the diet personalization study that we have been discussing, researchers found that a HbA1c of 5.5 % was actually the cutpoint for a person having a negative response to a meal.

However, it has to be noticed that only 59.3 % of the Health anxiety patients scored above this cutpoint at the index consultation and thus the fraction of patients above the cutpoint score seems quite stable in that very few Health anxiety patients seem to get well.

It is seen that 45.3 % of the patients with severe Health anxiety would still be ill at 24 months using this cutpoint for an «ill» response.

Separate cutpoints were indicated for problems because the distributions differed at the extremes, such that a universal cutpoint would identify unequal proportions across age by sex groups (Table I).

«Subclinical» (t - score ≥ 60) and «clinical» (t - score ≥ 63) cutpoints have been developed.

For example, among 12 - to 17 - month - olds, a cutpoint of 15 would identify fewer girls than boys (18.5 % vs. 24.3 %, Fisher exact test = 0.0586).

While awaiting clinical cutpoints, when the explicit goal is to identify children with more extreme psychopathology and / or delays in competence, one may employ more stringent cutpoints, based on this representative sample.

Thus, it is important to establish the BITSEA's clinical validity and to develop cutpoints that reflect clinically significant problems.

The BITSEA / P cutpoint and combined problem and competence cutpoints (BITSEA / PC) had good to excellent sensitivity and good specificity relative to the CBCL / 1.5 - 5 (Table III).

In addition, to inform the assignment of statistically at - risk cutpoints, BITSEA scales were evaluated for age and sex effects.

Of the 345 children positive on the Year 1 BITSEA problem and / or competence cutpoints, 59.4 % continued to be positive on the BITSEA in Year 2, χ2 (1, 1098) = 190.5, p <.01.

Based on age and sex findings, cutpoints were set to identify approximately 25 % of children in the at - risk range for problems and 10 % to 15 % as low in competence, a higher threshold than for problems, due to an expectation that significant social - emotional delays will be less common than significant problem behaviors.

To ensure comparability of data when comparing the performance of different BITSEA cutpoints, only subjects with complete data on both cutpoints were used (N = 1206).

Thus, LTA, if used on an instrument that is consistent over the developmental period in question, allows for the examination of the stability of internalizing and externalizing problems without the confounds that have plagued categorical, cutpoint - based research to date.
