Substance Use: Family-based Interventions to Prevent Substance Use Among Youth

The CPSTF finding is based on evidence from a systematic review of 60 studies conducted in the United States. Studies were identified from two sources:

• A broader systematic review published in 2016 (Allen et al., 39 studies, search period through March 2015)
• An update search (21 studies, search period January 2015–July 2022)

The systematic review was conducted on behalf of CPSTF by a team of specialists in systematic review methods, and in research, practice, and policy related to substance use prevention among youth.

Youth substance use is associated with increased risk for delinquency; academic underachievement; teen pregnancy; sexually transmitted infections; perpetration of, or experience with, violence; injuries; and mental health problems (U.S. Department of Health and Human Services 2016). Preventing or delaying substance use initiation among youth (defined in this review as children and adolescents ages 10-17 years) reduces later risk for substance use, substance use disorders, and overdose (U.S. Department of Health and Human Services 2016).

Recent trends in substance use among youth (Hoots et al. 2023) include the following:

• Increased availability of illicit fentanyl and other synthetic opioids
• Increased misuse of prescription drugs
• Increased availability of e-cigarettes and vaping products
• Changes in the legal and regulatory landscape for cannabis

Research highlights parenting as a key protective factor that can be enhanced through skill-based training interventions (Ladis et al. 2019, U.S. Department of Health and Human Services 2016). Interventions designed to strengthen preventive skills and practices among parents and caregivers (e.g., communication, positive relationship interactions, monitoring and control) have the potential to protect youth from initiation of substance use and other risk behaviors (Stockings et al. 2016, U.S. Department of Health and Human Services 2016).

Detailed results from the systematic review are available in the CPSTF Finding and Rationale Statement.

The systematic review included 60 studies conducted in the United States. Interventions were delivered primarily to families of youth ages 10-14 years.

Interventions reduced initiation of use for a variety of substances among youth

• Cannabis by 36.6% (4 studies)
• Alcohol by 12.1% (7 studies)
• Tobacco by 12.1% (7 studies)
• Illicit substances by 13.8% (4 studies)
• Prescription drug misuse by 58.1% (3 studies)

Interventions reduced measures of use among youth for the following substances

• Cannabis by 39.0% (13 studies)
• Alcohol by 33.8% (22 studies)
• Tobacco by 40.8% (9 studies)
• Illicit substances by 76.7% (3 studies)
• Prescription drug misuse by 91.4% (6 studies)

Interventions also led to the following outcomes:

• Reduced sexual risk behaviors and sexually transmitted infections (14 studies)
• Improved mental health symptoms (13 studies)
• Improved school-related outcomes (8 studies)

Detailed results from the systematic review are available in the CPSTF Finding and Rationale Statement.

The economic review included 11 peer-reviewed studies and two government reports, one from the Washington State Institute for Public Policy (WSIPP) and the other from the Substance Abuse and Mental Health Services Administration (SAMHSA 2008). WSIPP evaluated 14 programs and SAMHSA 2008 evaluated eight programs. Aside from one peer-reviewed study based in the United Kingdom, all evaluated interventions and programs were based in the United States.

Intervention cost reported in the three sources of evidence were:

• Peer-reviewed studies
  • Median per family $1,672 (6 interventions)
  • Median per family $1,672 (6 interventions)
• WSIPP
  • Median per family $655 (5 programs)
  • Median per participant or youth $680 (9 programs)
• SAMHSA 2008
  • Mean per family $988 (3 programs)
  • Median per participant or youth $677 (5 programs)

Intervention benefits reported in the three sources of evidence were:

• Peer-reviewed
  • $11,336 per case of averted misuse of opioids (1 study)
  • $147,412 per case of averted methamphetamine use (1 study)
  • $6,064 per youth lifetime benefits from averted tobacco, alcohol, and delinquency (1 study)
  • $259,818 lifetime cost averted per case of alcohol disorder (1 study)
• WSIPP
  • Median per family $2,211 (5 programs)
  • Median per participant or youth $2,510 (9 programs)
• SAMHSA 2008
  • Mean per family $9,767 (3 programs)
  • Median per participant or youth $8,299 (5 programs)

Cost-Effectiveness reported in two sources of evidence were:

• Peer-reviewed
  • Dominated or not cost-effective (1 intervention)
• SAMHSA 2008
  • Cost-saving (4 programs)
  • Median $21,426 per QALY gained (4 programs)

Cost-Benefit reported in three sources of evidence were:

• Peer-reviewed
  • Median benefit to cost ratio 5.8 (5 interventions)
• WSIPP
  • Median benefit to cost ratio 3.9 (14 programs)
• SAMHSA 2008
  • Median benefit to cost ratio 8.9 (8 programs)

Based on results from this review, findings are applicable to families of school-aged children and adolescents (ages 10-14 years at the time of the intervention) in the United States. Findings are applicable to interventions delivered in-person in home, school, and community locations in urban, suburban, and rural communities or remotely through printed, digital, or web-based modules.

CPSTF identified several areas that have limited information. Additional research and evaluation could help answer the following questions and fill remaining gaps in the evidence base. (What are evidence gaps?)

CPSTF identified the following questions as priorities for research and evaluation:

• How effective are interventions for families of American Indian, Alaskan Native, Native Hawaiian, Pacific Islander, and Asian youth?
• How effective are interventions for families of youth who identify as a sexual or gender minority?
• How effective are interventions in reducing development of substance use disorders?
• How effective are interventions for families of adolescents ages 15 years and older?

Remaining questions for research and evaluation identified in this review include the following:

• How effective are interventions in reducing vaping initiation and use?
• How effective are interventions in reducing polysubstance use among youth?
• How effective are interventions when focused just on parents and caregivers?
• Does intervention effectiveness differ by household income or parents’ and caregivers’ educational attainment or race/ethnicity?
• Does intervention effectiveness differ based on characteristics of implementers recruited from the community or schools?
• How can interventions improve recruitment and retention of fathers and male caregivers?

Economic Evidence Gaps

The following question is proposed as a priority for economic research and evaluation:

• What are economic outcomes for programs implemented for historically disadvantaged groups, particularly American Indian or Alaska Native groups?

Remaining questions for research and evaluation identified in the economic review include the following:

• What are the economic outcomes in urban areas?
• Is the intervention cost-effective based on more recent data?

• All studies were randomized controlled trials conducted in the United States (60 studies).
• Studies were conducted in urban and suburban communities (25 studies), rural communities (12 studies), and a mix of community types (6 studies).
• Interventions were delivered in community settings (12 studies), homes (10 studies), schools (6 (6 studies), and multiple locations (29 studies).
• Most interventions included sessions, modules, or activities for both parents and caregivers and participating youth (54 studies).
• Studies evaluated interventions delivered face-to-face in group sessions (27 studies), individual sessions (3 studies), or both (16 studies).
• Some studies did not include face-to-face sessions (12 studies) and instead used printed workbooks, websites, or digital modules.

When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.

The following considerations for implementation are drawn from studies included in the existing evidence review, the broader literature, and expert opinion.

Studies used several strategies to increase family recruitment and retention including the following:

• Community engagement
• Tailored intervention content and recruitment strategies
• Social and peer support including group meals and babysitting services
• Ongoing telephone contact

CPSTF also recommends intervention approaches related to the following:

• Preventing Excessive Alcohol Use
• Reducing Tobacco Use

Several organizations offer implementation guidance for family-based prevention strategies and interventions to address substance use.

• University of Colorado, Blueprints for Healthy Youth Development is a registry of scientifically rigorous and accessible prevention and intervention programs aimed at addressing youth health and behavior issues.
• Office of Juvenile Justice and Delinquency Prevention’s (OJJDP’s) Model Programs Guide offers a database of evidence-based juvenile justice and youth prevention, intervention, and reentry programs that covers issues including substance abuse, mental health, and trauma.
• California Evidence-Based Clearinghouse is a registry tool that can help organizations identify, select, and implement interventions for children and families affected by the child welfare system.
• Prevention Technology Transfer Center (PTTC) Network provides technical assistance resources to improve implementation and delivery of effective substance abuse prevention interventions.
• SAMHSA’s National Youth Substance Use Prevention Campaign provides resources for parents and caregivers, educators, and community members to prevent substance use.

The following resources address issues that may be useful for implementing these interventions in specific communities:

Tribal families

• Tribal Training and Technical Assistance Center | SAMHSA
• Tribal Youth Resource Center – Resource Library

Military families

• Clearinghouse Continuum of Evidence (Continuum)

Foster families

• Title IV-E Prevention Services Clearinghouse

The following resources address specific substance use issues:

• Preventing Marijuana Use Among Youth | samhsa.gov [PDF – 7.2 MB]
• Opioid Prevention Programs & Tools | HHS.gov
• E-Cigarette Resources | American Lung Association
