T tests did not show any difference in standard PPVT-R scores between the high- and low-engagement-of-reflection groups, t < 1, but indicated that the group with a high level of need for reflection had significantly lower standard PPVT-R scores than the group with a low level of need for reflection, r(107) = 2.
T tests did not reveal any difference in standard PPVT-R scores between the high-insight and the low-insight groups, t < 1.
1995), the PPVT-R was the best predictor, followed by the McCarthy GCI.
The difference in sample might explain the discrepancy in results between the analyses with McCarthy GCI and PPVT-R scores as predictors and the analyses with PLAI scores as predictors.
After controlling for maternal predictors and their interactions with gender, boys scored higher on the PPVT-R, had more behavior problems, but had somewhat easier temperaments.
The regression model accounted for 31% of the variance in girls' S-B scores, 23% of the variance in their PPVT-R scores, and 29% of the variance in their CBCL scores.
For logistical reasons, we were unable to administer the PPVT-R individually to each student.
We determined the end point for the test by conducting a small pilot study in which we delivered the PPVT-R individually to two 2nd-grade students with strong linguistic aptitudes.
The pretest PPVT-R was a significant predictor of the following posttests: SBIS:FE Test Composite Score, SBIS:FE Verbal Reasoning Scale, PIAT Reading Comprehension, Walker-McConnell Total Score, and Walker-McConnell Peer-Preferred Social Behaviors.

The predictors of warmth and positive verbal exchanges were significant when predicting 30-month Stanford Binet and 44-month PPVT-R
scores, even after demographic risk index factors (conditions of low income, low education, minority status, and absence of male partner) were taken into account (Hann, Osofsky, & Culp, 1996).
To determine the degree to which random assignment was successful in forming comparable groups, one-way analyses of variance (ANOVAs) were performed on the McCarthy GCI, PPVT-R
, TELD, and TERA pretests.
