Table 2 contains the results for the 2 parental behavior scales: parental monitoring and communication regarding sex. For ease of presentation, each of the scale score distributions was trichotomized into groups indicating high (>2.67), moderate (2.0-2.67), and very low (<2.0) rates of parental influence. Approximately 70% of the children reported that their mothers watched them the most at home. Grandparents were the next most frequent guardian (12%), followed by aunt/uncle (6%), father (5%), and someone else (7%). Analyses of differences between these types of guardian revealed that mothers were more likely than other guardians to engage in monitoring (t349=3.13, P=.0001, ΔR2=0.025) and discussion regarding sex (t347=3.07, P=.0001, ΔR2=0.024). These analyses also revealed that older children reported less monitoring than younger children (t349=3.62, P=.001, ΔR2=0.034) but no differences concerning communication about sex (t349=.56, P=.57). In addition, girls reported more parental influence of both types than boys (t349=4.13, P=.0001, ΔR2=0.044, and t348=6.75, P=.0001, ΔR2=0.114, respectively). On average, only 11% of boys reported high levels of communication from their parents regarding sexual risks, whereas more than a third of girls reported such discussions.
