Regarding reliability and validity, the AGVQ was developed on the basis of research with over 2,000 demographically diverse adolescents.
Analysis performed (Shapiro et al, 1997) revealed that there were significant relations between factor scores of the AGVQ and self-reported gun ownership: For Aggressive Response to Shame t (1156) = 6.
Four additionally distinct yet conceptually related measures constituted this study's dependent measures of aggression (MPRI-C, MPRI-P, AGVQ, and School Detention / Referral Records).
Univariate analysis was again utilized to investigate where such differences lie, and in this case revealed that the AGVQ variable was significantly different across treatment groups at post test, F (1, 82) = 10.
With regard to aggression, a separate ANOVA procedure was run to test if groups were significantly different on the AGVQ variable after 1 year following treatment.
