Safe, Healthy, Adolescent Relationships and Peers (SHARP-Teen)

May 10, 2023 updated by: University of Oregon

Preventing Drug Use and Risk Behaviors in Adolescent Girls

The Safe, Healthy, Adolescent Relationships and Peers study seeks to understand some of the factors that contribute to the behaviors and health of teen girls, such as girl's friendships, their dating behaviors, their risk-taking behaviors, and their knowledge about how to make healthy choices. This study will inform us on ways to help teen girls engage in safe and healthy relationships and adjustment.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Initiation of drug use and participation in sexual-risk behaviors such as having multiple sexual partners, unprotected sexual intercourse, and intercourse with drug users are all too common among girls with at-risk histories, such as those who have experienced poverty, abuse, neglect, or been in the juvenile justice system. Studies consistently find that these girls have disproportionately high rates of these problems that, in addition to increasing risk for negative outcomes, have other costly sequelae such as drug addiction, early pregnancy, sexually-transmitted infections (STIs) and HIV contraction, delinquency, and early mortality (e.g., Santelli et al., 2001; Stueve et al., 2005). In our prior work, the investigators showed that the investigators could prevent early onset sexual intercourse and tobacco and marijuana initiation in pre-teen girls in foster care. Although this intervention, delivered to girls who were 11-years old and had not yet entered middle school, demonstrated efficacy, the investigators know very little about how to prevent the more serious and costly sexual-risk and illicit drug use behaviors in at-risk girls during the high school years, a period of risk for engagement in such behaviors. This study builds from this prior work to develop a new intervention for teenage girls with early adversity.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
122

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

13 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Services as Usual
Participants continue with any services they may be receiving outside of the study.
Behavioral: Services as Usual
Services as usual as provided by community service organizations from which the sample was drawn.
Experimental: Parent Ed. and Youth Skills Coaching
The experimental intervention will have two components: (1) a caregiver parenting group, including all caregiver types (biological, foster, kinship), that meets weekly for 90-minutes for four months, focused on increasing parenting skills, and (2) a Life Coach component where trained and supported skills coaches meet individually with youth weekly for 60 minutes over the same four-month period to build the girls' social skills and peer/partner relationships skills.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Delinquency measured by official arrest records and standardized questionnaires
Time Frame: Up to 12 months
Reduction in delinquent behaviors for teens participating in the intervention arm measured by official arrest records and standardized questionnaires, including the Youth Symptom inventory, the Elliott Self-report Delinquency Scale, the Achenbach System of Empirically Based Assessment, and the Parent Daily Report.
Up to 12 months
Sexual Risk Behavior
Time Frame: Up to 12 months
Reduction in high risk sexual behaviors for teens participating in the intervention arm measured by standardized questionnaires, including Partner and Peer Behavior, Conflict in Adolescent Dating, Sexual Health Scale, and the Parent Daily Report.
Up to 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Parenting measured by change in parenting practices for parents participating in the intervention arm measured by standardized questionnaires
Time Frame: Up to 12 months
including the Monitoring and Parent-Child Relationship, the Parent Practices Scale, the Parent Daily Report, and the Unrevealed Differences Questionnaire.
