Summary: In this randomized controlled trial, participants were recruited via online, newspaper, community and radio advertisements. Nine-hundred and sixteen eligible mother-child dyads were randomly assigned to an intervention (Internet for 84%/ CD-rom for 16%: n=458) and a no-test control condition (n=458). All participants completed baseline, as well as two annual follow-up data collections that lasted approximately 45 minutes each. Intervention arm participants received monetary incentives following baseline data collection and annual booster sessions, which took place after each follow-up. Control arm participants also received incentives for completing follow up assessments only.
Retention rates were high across groups (91%) at 2-year follow-up. No outcome differences were observed between the two delivery vehicles (Internet or CD-ROM) at either annual follow-up. By Year 2, girls who received the prevention program showed significantly higher positive changes than their control counterparts on 18 of 21 measured variables, including fewer occasions of use of alcohol, marijuana, prescriptions for non-medical purposes, and inhalants, as well as intentions to use alcohol, tobacco or drugs in the future (exceptions were body image, depression, past-30 day use of cigarettes). Mothers in the intervention reported better 2-year follow-up outcomes compared with controls on all measures (observance of family rituals, communication with daughters, establishment of family rules regarding substance use, monitoring out-of-home activities, and personal weekly alcohol consumption).
Take Away: There is strong empirical support for this computer-delivered, substance abuse prevention program designed for mother-daughter dyads.

Summary: This study reports the 1-year follow up results of a randomized controlled trial. Study participants were 591 eligible pairs of adolescent girls and their mothers (recruited via online, newspaper, community and radio advertisements) who were randomly assigned to the 9-session, Web-based intervention (n=252) and a no-intervention control condition (n=339). All participants completed pre- and post-intervention measures, as well as a 1-year follow-up measurement. Dyads in both conditions received monetary incentives for completion of outcome measures.
At post-intervention and 1-year follow-ups, girls in the intervention group, as compared to the control group, demonstrated better outcomes on all past-month substance use measures, as well as on communication, family rules, monitoring, perceptions of peer drug use as normative behavior, and ability to refuse peer pressure. The groups did not differ on depression, problem solving, or body esteem. Relative to mothers in the control group, mothers in the intervention group reported significantly better outcomes on measures of communication with their daughters, rules against their daughters’ substance use, and monitoring of their daughters’ out-of-home activities.
Take Away: This computer-delivered, parent-involvement substance use prevention program may lead to positive changes in girls and their mothers by reducing the risks of substance use and increasing protections against future substance use.
