A Chi-Square (Ҳ 2 ) test on independence was used to determine whether or not there was a dependency between children’s Intellectual Ability as perceived by teachers and children’s CBVS Action Choices and Justification Choices. Are there significant differences in the proportion of children’s responses on the CBVS Justification Choice subscales (Prosocial/Care, Aggressive/Retribution, Justice/Fair) and CBVS Action Choice subscales (Prosocial, Aggressive)? A Chi-Square (Ҳ 2 ) test of independence was used to determine whether children’s Action Choices (e.g., Prosocial, Aggressive) were dependent on their Justification Choices (e.g., Prosocial/Care, Aggressive/Retribution, Justice/Fair). Tests for the difference in proportions were performed to determine if there were interactions between variables. Tests for the difference in proportions were performed by participant children’s Gender (e.g., male, female), Story Character Form (e.g., bystander, victim), and Story Form of Victimization (e.g., physical, relational). Does teacher-report CBS Behavior with Peers (e.g., Prosocial With Peers, Aggressive With Peers) relate to children’s CBVS Action Choices (e.g., Prosocial, Aggressive)? Subscale means and standard deviations for the CBS and CBVS subscales were computed by averaging children’s additive scores across all of the items contained within a subscale sum. The internal consistency of each subscale was estimated with Cronbach’s alpha. Alphas for the two CBS subscales were moderately high to high in magnitude. A stepwise backwards logistic regression model was used to determine if teacher-report scores on Prosocial With Peers and Aggressive With Peers subscales on the CBS predicted children’s Prosocial and Aggressive Action Choices on the CBVS. The backwards elimination analysis was used as a means of comparing the CBS continuous rated data with the CBVS nominal categorical data, which started out with CBS 66

Prosocial with Peers and CBS Aggressive with Peers as the predictors of CBVS Action Choices in the model. At each step the predictors in the model were evaluated and eliminated if they met the significance criterion of p > .05 for removal in order to least reduce the R 2 (Hosmer & Lemeshow, 1989; Pedhazur, 1997). Do the teacher reports of children’s social behavior with peers as assessed by the CBS Prosocial With Peers subscale and the Aggressive Behavior With Peers subscale of the Child Behavior Scale (CBS, Ladd & Profilet, 1996) relate to the children’s CBVS Justification Choices that are coded as either Justice/Fair, Prosocial/Care, Aggressive/Retribution? A multinominal Logistic Regression model based on CBS subscales (e.g., Prosocial with Peers, Aggressive with Peers) was used to predict the CBVS Justification Choice subscales (e.g., Prosocial, Aggressive/Retribution, Justice/Fair) using Justice/Fair as the baseline variable. Multinomial logistic regression is used when the dependent variable, Action and Justification Choices, in question is nominal (a set of categories which cannot be ordered in any meaningful way) and consists of more than two categories (Prosocial vs. Aggressive actions, Prosocial/care vs. Aggressive/Retribution vs. Justice/Fair justifications) (Harrell, 2001). Multinomial logistic regression is appropriate in cases where the response is not ordinal in nature as in ordered logistic. In contrast, ordered logistic regression is used in cases where the dependent variable in question consists of a set number (more than two) of categories which can be ordered in a meaningful way while multinomial logistic regression is used when there is no apparent order. The multinomial logistic model assumes that data are case specific; that is, each independent variable (e.g., CBS Prosocial with Peers and CBS Aggressive with Peers) has a single value for each case. The multinomial logistic model also assumes that the dependent CBVS variables cannot be perfectly predicted from the independent CBS variables for any case. As with other 67
