“…Alternatively, it may be that children who participated in the study were, on average, slightly above average in terms of school-based achievement and developmental outcomes. Indeed, differences in parental consent have been identified as a major source of bias in sampling children (Pless, Hagel, Zhang, & Magdalinos, 2011). Nonetheless, such bias appears modest and sufficient variably exists to result in meaningful analysis.…”

Young school children commonly use a range of digital media technologies including television, video games, and the Internet. Parents of 40 children in first and second grade completed a questionnaire that queried: 1) demographics, 2) number of home digital media devices, and 3) extent and nature of child use of those devices. Teachers who taught these first and second grade students completed a rating scale on the school achievement and developmental ability of participating children. The pattern of correlations among measures of child achievement/ability and measures of teacher-reported internet literacy and parent-reported home digital media use suggests that internet use has many positive associations and that playing video games and watching television have some negative associations. For example, children’s mathematics skills were postively correlated with use of the Internet but negatively correlated with televsion viewing. In some cases, children who used the Interent alone appeared more competent than children who used the Internet with an adult. Digital media use during childhood is a complex phenonema with a range of potential outcomes.Simplistc approaches are counterproductive. Key words: child development, children, digital media, internet, internet co-use.

Different approaches to obtaining consent for follow-up result in biased samples

Abstract: Caution is needed when interpreting results from studies using hospital samples, especially when wording of consent for follow-up requires direct affirmation.
