Participants were tested one-on-one by examiners, who were carefully trained by project psychologists to administer all tasks in an efficient and standardized manner using scripted directions and prompts. Testing occurred in the school setting, research center testing rooms, and community libraries. Tasks were administered using pencil and paper, or on touch-screen laptops with either e-Prime(Schneider, Eschman, & Zuccolotto, 2002a, 2002b; Stahl, 2006) or Medialab (Jarvis, 2004) with the audio-computer assisted self-interviewing (ACASI) method of both visual and aural presentation. Use of ACASI served to maximize subjects’ comfort in answering truthfully about their behaviors as they completed the questionnaire (Metzger et al., 2000) while also reducing differences that might result from reading a self-administered survey.
