About

This project is aimed at parents with a teenager who is already starting to use drugs. The study will test a new, innovative version of a brief intervention. This program will be home based rather than implemented 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 study. Two samples, 110 families each, will participate in the trial. Families will be assigned to either an intervention or control condition. 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.

Full description

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.

Home-Based Intervention

Experimental group

Description:

Parents will receive a 1-session training on how to deliver a 3-session intervention across a 3-week period. The intervention program begins with a 3 and a half hour training session delivered by the staff Trainer to the participating parent. At the conclusion of training, the parent will be given the intervention manual and supplemental materials. The trainer will phone the parent shortly before session 1, in between each intervention session, and after the third intervention (four phone calls total) to review the objectives and tasks associated with that week's intervention session and to help prepare for the coming session. At the final phone call between the parent and trainer (after the third week), the trainer will deliver to the parent the follow-up resources.
