Model description

Level 4 Group Teen Triple P is part of the Triple P multi-level system of family support and is specifically for any family with a young person aged between 12 and 16 years.

The intervention is delivered by a practitioner with training in psychology or a related helping profession. It is delivered to groups of 3 to 12 parents over a period of eight weeks.

Parents participate in four (2-hour) group sessions (of up to 12 parents each), as well as three (15–30-minute) individual telephone consultations. During these sessions, parents learn practical strategies for managing problematic adolescent behaviour and improving family communication.

During the first four group sessions, parents learn about the causes of common adolescent behavioural problems and risks, strategies for setting specific goals for promoting positive adolescent behaviour, managing difficult behaviour, and anticipating high-risk situations.

After these group sessions, three (15–30-minute) individual telephone consultations take place to help parents  fine-tune the implementation of the newly learned parenting strategies and to problem-solve any implementation difficulties they may be having.

As part of the final (2-hour) group session, parents re-convene to review progress and discuss the use of additional skills to facilitate generalisation and maintenance of positive changes.

Throughout the course of the intervention, Group Teen Triple P practitioners help parents learn and practise new skills through continuous, constructive feedback. Methods used to promote learning include small group discussions, videos, practitioner demonstrations, behavioural rehearsal, and role-play.

Age of child

12 to 16 years old

Target population

Why?

Science-based assumption

High levels of autonomy during adolescence increases the risk of substance misuse and antisocial behaviour which in turn, can negatively impact young people’s life chances in later adulthood.

Science-based assumption

Family risk factors such as inadequate parental monitoring and family conflict are modifiable risk factors that can reduce the risks associated with the adolescent years.

Who?

Science-based assumption

All parents benefit from knowledge about the risks occurring during adolescence and the parenting behaviours that can mitigate these risks.

How?

Intervention

Parents learn strategies:

For improving family communication

Setting age-appropriate limits

Granting age-appropriate autonomy.

What?

Short-term

Improve parent–adolescent relationship

Less conflict within the family

Parents provide age-appropriate monitoring and autonomy granting.

Medium-term

Increased adolescent autonomy and responsible decision-making

Improved adolescent behaviour.

Long-term

Reduced risk of antisocial behaviour and substance misuse during the adolescent years

Increased school achievement and entry into the workforce.

Who is eligible?

Parents of an adolescent child, aged between 12 to 16 years.

How is it delivered?

Group Teen Triple P is delivered by a single Triple P practitioner. Over the course of eight weeks, parents participate in four (2-hour) group sessions, three (15–30-minute) individual telephone consultations, and a final (2-hour) group session.

What happens during the intervention?

In the first four (2-hour) group sessions, parents actively participate in a range of exercises to learn about the causes of common adolescent behaviours, how to set specific goals, promote positive adolescent behaviour, manage difficult behaviour, and plan ahead for high-risk situations.

After these group sessions, three (15–30-minute) individual telephone consultations are conducted. The aim of these consultations is to assist parents in fine-tuning the implementation of the newly learned parenting strategies, and to problem-solve any implementation difficulties they may be having.

As part of the final (2-hour) group session, parents re-convene to review progress, and to discuss the use of additional skills to facilitate generalisation and maintenance of positive changes.

Who can deliver it?

The practitioner who delivers this intervention can come from a range of professions (e.g. school counsellor, nurse, psychologist, social worker, or parent educator).

What are the training requirements?

Practitioners attend three days of training. They also attend a one-day pre-accreditation workshop, and a half-day accreditation session. Booster training of practitioners is not required.

How are the practitioners supervised?

Practitioner supervision is provided through the following processes:

  • It is recommended that practitioners are supervised on a quarterly basis in two-hour sessions, by one practitioner
  • Triple P has also developed its own Peer-Assisted Supervision and Support Model (PASS), whereby practitioners can provide and receive structured feedback from each other while they deliver the intervention. PASS sessions are conducted in small groups of 6–8 practitioners and run for 1–2 hours every month.
  • Triple P UK can also provide clinical support for practitioners, either as a one-day workshop or a small group phone consultation with a Triple P Trainer.

What are the systems for maintaining fidelity?

Intervention fidelity is maintained through the following processes:

  • Training manual
  • Other printed material
  • Other online material
  • Video or DVD training
  • Face-to-face training
  • Fidelity monitoring
  • Quality assurance checklist
  • Practitioner accreditation
  • Intervention fidelity checklists, completed by practitioners after each session
  • Supervision and practitioner support, by use of the Triple P Peer Support Network.

Is there a licensing requirement?
