However, when all the variables in the model were included in the regression analysis, optimism
explained additional variance in physical well - being but not in psychological well - being.
It is important to note, however, that the percent
of additional variance explained was quite small, only 2 %.
In general, the results suggest that timing of first discussion of sexual intercourse
contributes additional variance in several sexually risky behaviors beyond that contributed by the amount of communication with both fathers and mothers.
The 10 - piece kit
offers additional variances, such as shorter paddles and different D - pad styles, for personal preference: 2 Standard Analog Sticks, 2 Mid-Tall Analog Sticks, 2 Domed Mid-Tall Analog sticks, 2 Upper Paddles, 2 Lower Paddles, and 2 Directional Pads.
To test whether results were still significant under the assumption that data were missing at random, we conducted multiple imputation and ran our primary analyses across 10 imputed data sets, 37 adjusting for
additional variance across imputations.
However, only the 24 - month classification predicted maternal report of externalizing and internalizing behavior problems at age 3.5 years,
with additional variance accounted for by selected measures of child emotional and behavior regulation from the same assessment.
Study 2 recruited 127 adolescent - parent dyads (Adolescent Mage 15.30, SD = 2.30; 58 % female; Parent Mage = 46.01, SD = 11.02; 67 % mothers) and found that parent - reports of the degree to which they are aware of their son / daughter's strengths and the degree to which they encouraged their son / daughter to use their strengths
explained additional variance in life satisfaction in adolescents beyond their adolescent son / daughter's own strengths - knowledge and strengths - use.
Individual Efficacy has no significant relationship with achievement, and the more complex model explains
no additional variance.
The additional variance explained by the interaction term was small -LRB-.01) but in the range typically found in the literature for interaction terms (Frazier, Tix, & Barron, 2004).
