What is Growing up with Media?
 A longitudinal online survey of a representative national sample of 1,588 young people, ages 10 through 15 at Wave 1, who use the Internet regularly.
 “Regular Internet use” was defined as using the Internet at least once in the past 6 months from any location.
 Parents and guardians first completed a short online survey; approximately 5 minutes.
 Parents were a member of the Harris Poll Online (HPOL) opt-in panel and residents of the U.S.
 With parental consent, youth completed an online survey; approximately 25 minutes.
 Youth sample was stratified based on age and sex.
 Adult participants received $15 and youth a $20 gift certificate.
 Data were collected across three time points: – Wave 1: August – September, 2006 – Wave 2: September – December, 2007 – Wave 3: August – December, 2008
 Data were weighted to match the U.S. Population of adults with children between the ages of 10 and 15 years.
 Propensity scoring was applied to adjust for the adult’s (i.e., recruitment target) propensity to be online and in HPOL.
