Initial phone screening was conducted in 2001–2002 by the Survey Research Center of the University Center for Social and Urban Research (UCSUR) at the University of Pittsburgh. Mothers were asked about their interest in being contacted to participate in a study involving regular interviews with their 8- or 10-year old child, with them, and with their partner (if present). Tween to Teen project staff subsequently re-contacted potential participants to further assess eligibility, to determine if families met recruitment quotas, and to schedule a computer-assisted interview in participants’ homes or at our research offices.
