    Cronbach's Alpha subjective scales (α range from .69 to .88); Cronbach's Alpha daily activities (α=.55); Cronbach's Alpha victims of aggression (α=.29)

    Validity: Construct (Convergent and Discriminant)

    In subjective scales the discrimination index for 23 items ranged from .87 to .96; In objective scales, the discrimination index ranged from .74 to .94; Daily activities item ranged from .28 to.53

    Using subjective items, EFA resulted in eight dimensions that accounted for 75% of the variance
