Several univariate analyses of variance were conducted to
determine whether co-playing differed as a function of family
structure or ethnicity, and they were not statistically significant.
Further, correlations revealed that co-playing was not related significantly
to family income, but was related negatively to mothers’
age (r .17, p .01; there was no significant correlation with
fathers’ age). Analyses of variance were also conducted to determine
whether study variables differed as a function of gender
of the adolescent, and results revealed that age-inappropriate
games, video game use, internalizing, child-reported delinquency,
and mother- and child-reported prosocial behaviors
differed as a function of gender, with boys more likely to play
age-inappropriate games as well as have higher video game
use and delinquency; and girls having higher levels of internalizing
problems and prosocial behaviors (Table 1).
