Model description

Strengthening Families 10–14 (SF 10–14) is for any family with a young person aged between 10 and 14 years. The parents and young person attend seven two-hour sessions where they learn how to communicate effectively, agree appropriate limits, and resist peer pressure to use drugs and alcohol.

SFP 10-14 is delivered by three practitioners to groups of eight to 12 parents. Because parents attend with their children, up to 36 people may be present in a group session. Ideally, two practitioners co-deliver the parenting sessions and one practitioner delivers the young person sessions.

During the first hour, the parents and young people attend separate skill-building groups. These sessions make use of an instructional video that provides the basis for a group discussion and practice activities.

The parents and child then come together for the second hour for supervised family activities. The topics for each session are provided in Table 1.

Table 1: SF 10-14 topics for weeks 1 to 7
Parent sessions Youth sessions Family sessions
1. Using love and limits Having goals and dreams Supporting goals and dreams
2. Making house rules Appreciating parents Appreciating family members
3. Encouraging good behaviour Dealing with stress Using family meetings
4. Using consequences Following rules Understanding family values
5. Building bridges Handling peer pressure 1 Building family communication
6. Protecting against substance misuse Handling peer pressure 2 Reaching our goals
7. Using community resources Reaching out to others Putting it all together and graduating

Youth sessions focus on setting and strengthening goals, dealing with stress and strong emotions, communication skills, increasing responsible behaviour and improving skills to deal with peer pressure.

Parents discuss the importance of both nurturing their youth while, at the same time, setting rules, monitoring compliance, and applying appropriate discipline. Topics include: making house rules, encouraging good behaviour, using consequences, building bridges, and protecting against alcohol and substance misuse.

Between 6 and 12 months after the seventh session, the parents and young people return for four more booster sessions that occur at regular intervals. During these sessions, parents discuss methods for handling parental stress, communicating when partners don’t agree, and reinforcing their earlier skills training. Young people focus on making good friends, handling conflict, and reinforcing skills learned in the first seven sessions. The topics for the booster sessions are provided in Table 2.

Table 2: SF 10-14 topics for booster sessions
Parent sessions Youth sessions Family sessions
1. Handling stress Handling conflict Understanding each other
2. Communicating when you don’t agree Making good friends Listing to each other
3. Reviewing love and limit- settings skills Getting the message across Understanding family rules
4. Reviewing how to help with peer pressure Practising skills Using family strengths

Age of child

10 to 14 years

Target population

This intervention targets the general population of school-aged children

Why?

Science-based assumption

Increasing levels of autonomy in adolescence increases the risks associated with substance misuse and antisocial behaviour.

Science-based assumption

Effective parenting practices and positive family relationships can decrease the risks associated with the adolescent years.

Who?

Science-based assumption

All families with a young person can benefit from knowledge about the risks associated with adolescence autonomy and substance misuse and strategies for managing these risks.

How?

Intervention

Parents and young people learn:

How to communicate effectively

Agree age-appropriate autonomy for the young person

Agree age-appropriate limits

Manage family conflict

Enforce age-appropriate consequences

Manage and resist negative peer pressure.

What?

Short-term

The relationship between the parents and the young person improves

Family conflict decreases

Parents provide age-appropriate autonomy and limits.

Medium-term

The young person is at less risk of behavioural problems

The young person makes responsible decisions and can better manage their autonomy.

Long-term

The young person is at reduced risk of substance misuse and antisocial behaviour problems

The young person is better prepared to make a successful transition into adulthood.

Who is eligible?

All parents with a young person between 10 and 14 years.

How is it delivered?

Strengthening Families (10-14) is delivered in seven sessions of two hours’ duration each by three trained practitioners (one lead practitioner and two co-practitioners), to groups of between 8 and 12 families.

What happens during the intervention?

  • During the first hour, the parents and children attend separate sessions on a related family skill (e.g. family communication or peer-refusal skills for substance misuse).
  • These sessions make use of an instructional video that provides the basis for a group discussion and practice activities.
  • During the second hour, the parents and children are reunited to review and practise skills and competencies together.

Who can deliver it?

The practitioner who delivers SF 10 – 14 typically has a qualification and experience in education or youth work.

What are the training requirements?

The practitioners have three full days of intervention training. Booster training of practitioners is recommended.

How are the practitioners supervised?

It is recommended that practitioners are supervised by one host-agency supervisor

What are the systems for maintaining fidelity?

Intervention fidelity is maintained through the following processes:

  • A certification training where the research is presented, activities are modelled, and practice sessions are encouraged
  • A comprehensive manual with detailed lesson plans
  • Fidelity observations throughout the seven weeks of the intervention.

Is there a licensing requirement?

No

SF 10-14’s most rigorous evidence comes from a single RCT conducted in the United States consistent with Foundations’ Level 3 evidence strength criteria.

This study observed a wide variety of benefits for SF 10-14 parents and children compared to families who did not attend the intervention, including a number of long-term benefits.

  • Children in the intervention group showed statistically significant reductions in alcohol initiation behaviours at 1.5 and 2.5 years post-baseline.
  • At 4 years post-intervention, they exhibited fewer aggressive and hostile behaviours, as well as less aggressive and destructive conduct.
  • At 6 years post-intervention, statistically significant improvements in academic success and school engagement, as well as reductions in student substance related risk were evident. Reduced polysubstance use and a reduced rate of increase in internalising symptoms were also reported for the intervention group. Studies also reported reductions in substance use during sex, the number of sexual partners in the past year, and sexually transmitted diseases for the intervention group.

SF 10-14 can be described as evidence-based: it has evidence from at least one rigorously conducted RCT or QED demonstrating a statistically significant positive impact on at least one child outcome.

While this intervention has robust evidence from the United States suggesting positive impact, the findings from recent European trials have been more equivocal, showing less positive results. However, these more recent trials have not been as methodologically robust as the US evidence, therefore we cannot draw strong conclusions from them. Please see reference list for details of all trials identified. The study contributing towards the rating tested the ‘Iowa Strengthening Families Program’, which Strengthening Families 10-14 was formerly known as. It is based on the same seven-session model.

Evidence ratings:

Rated 2: Has preliminary evidence of improving a child outcome from a quantitative impact study, but there is not yet evidence of causal impact.

Rated 2+: Meets the level 2 rating and the best available evidence is based on a study which is more rigorous than a level 2 standard but does not meet the level 3 standard.

Rated 3: Has evidence of a short-term positive impact from at least one rigorous study.

Rated 3+: Meets the level 3 rating and has evidence from other studies with a comparison group at level 2 or higher.

Rated 4: Has evidence of a long-term positive impact through at least two rigorous studies.

Rated 4+: Meets the level 4 rating and has at least a third study contributing to the Level 4 rating, with at least one of the studies conducted independently of the intervention provider.

Rating has a *: The evidence base includes mixed findings i.e., studies suggesting positive impact alongside studies, which on balance, indicate no effect or negative impact.
