The videotaped data will be coded and analyzed by the research staff. The videotapes and all data will be identified only by ID numbers; all personal information will be removed. Your personal information will be stored in a secured computer file. That computer is disconnected from the Internet to provide maximum security. The analyses will focus on statistical trends that characterize groups of children (for example, girls compared to boys; children's behavior at the entry to the study compared to behavior at the end of the study), and not on individual children or mothers. The record of your participation will be kept confidential to the extent permitted by law.
