Home-Based Program to Help Parents of Drug Abusing Adolescents

Little attention has been paid to the large group of adolescents who use substances but are
not, or not yet, dependent and who could successfully reduce substance use through early
intervention. Brief interventions (BI) that are based in cognitive-behavioral and
motivational interviewing (CB-MI) strategies provide an option for such mid-level drug
abusers (e.g., DSM-IV substance abuse disorder), and extant research on them suggests this
approach can be effective with youth.

Winters and colleagues have studied with controlled designs the efficacy of brief
interventions for application to mild-to-moderate substance abusing adolescents. These
studies have used the more traditional approach of counselor-led interventions. This program
will be parent-led rather than directed by a counselor in a clinical setting.

The stage I activities will involve manual development, parent training development, and a
small feasibility study; Stage II involves an efficacy trial. Two samples, 110 families
each, will participate in the trial. Families will be assigned to either an intervention
or control condition. Data to quantify intervention effects will be obtained by
interviewing adolescents and the target parent at multiple time points (baseline and, 3-, 6-
and 12-months post baseline). The investigators hypothesize that the home-based
intervention will be superior to the control condition. In addition, the investigators
expect response to the intervention by the adolescent to be mediated by motivation,
cognitions, problem solving, peer drug use, parenting skills and parent self-efficacy.
Secondary analyses will focus on additional predictors of intervention effects, and analyses
of parent adherence, parent acceptance, and of training adherence.

The final product of the work will be a tested comparative intervention protocol that is
shaped in an engaging and useful presentation format for use by parents.
