Group Lifestyle Triple P

Group Lifestyle Triple P is a 12-week intervention for parents or caregivers who are concerned about the weight and activity level of a child between 4 and 11 years old. Groups of up to 10 parents attend nine 90-minute group sessions delivered by a Triple P practitioner. During each session, parents learn strategies for managing their child’s weight through lifestyle changes. Parents also receive three individual phone conversations that tailor the group content to the family’s individual needs.

Model description

Group Lifestyle Triple P is part of the Triple P multilevel system of family support, developed specifically for parents or caregivers who have concerns about the weight and activity of a child between 4 and 11 years old.

During the sessions, parents learn effective strategies for managing their child’s weight by introducing gradual permanent changes in their family’s lifestyle. This includes methods for providing healthy food choices, increasing children’s physical activity and using incentives to encourage the child to make better health-related choices.

The session topics are as follows:

  • Session 1, Preparing for change: covers working as a group, what ‘overweight’ means, how it can be treated, readiness for change, and keeping track.
  • Sessions 2–3: focus on understanding of nutrition and physical activity. Parents learn how to encourage healthy eating and activities in their children and about increasing their child’s self-esteem.
  • Session 4, Using rewards and modifying recipes: covers motivating children to be healthy, the different types of fat, and how to reduce fat intake.
  • Sessions 5–7: focus on limiting sedentary behaviour, playing active games, managing hunger and overeating and providing healthy meals and snacks.
  • Session 8, Managing problem behaviour: parents learn how to manage problem behaviour, develop parenting routines, and prepare for the weekly telephone sessions.
  • Sessions 9–10, Using Lifestyle Triple P strategies: consist of a number of telephone consultations, providing the parent with an opportunity to update the practitioner with their family’s progress and discuss any issues.
  • Session 11, Planning ahead: parents return to the group to learn about family survival tips, high-risk situations, planned activities, and prepare for fortnightly telephone sessions.
  • Sessions 12–13, Using planned activities: consist of further telephone consultations. These provide the parent with an opportunity to update the practitioner with their family’s progress and discuss any issues.
  • Session 14, Programme close: parents return for a final group session to review progress, look at ways to maintain the healthy changes, plan for the future, and to bring closure to the intervention.

At the start of the intervention, each parent receives a workbook summarising the session content, and suggestions for  between-session tasks. Parent learning is also reinforced during the group sessions through presentations, group discussion, DVDs, live demonstrations of parenting skills, role-play, peer modelling, and small-group problem-solving exercises. Parents also receive four individual telephone consultations with the practitioner to update the practitioner on their family’s progress and discuss any issues.

Age of child

5 to 10 years

Target population

Parents of children aged between 5 to 10 years where the parent believes their child is overweight or obese

Disclaimer: The information in this section is as offered/supported by the intervention provider.

Why?

Science-based assumption

Excess weight in early childhood increases the risk of obesity and diabetes in later childhood and adulthood

Over a quarter of all children in the UK are currently obese.

Science-based assumption

Family diet and low levels of physical activity increase the risk of childhood obesity and poor physical health.

Who?

Science-based assumption

All families can benefit from increased information about a healthy lifestyle.

How?

Intervention

Parents learn strategies for healthy eating and physical exercise that can be incorporated into their daily routines.

What?

Short-term

Parents and children have a better understanding of healthy dietary and activity patterns

Parents and children incorporate healthy diet and physical activities into their daily and weekly family routines.

Medium-term

Children reach and maintain a healthy BMI for their height and age.

Long-term

Healthy eating habits in adulthood

Increased physical activity in adulthood

Reduced obesity risk in childhood and adulthood.

Who is eligible?

Families are eligible if they consider their child to be overweight, the child is between 5 and 10 years of age, and the parent agrees to attend a 12-week intervention.

How is it delivered?

Group Lifestyle Triple P is a 12-week intervention that consists of nine 90-minute group sessions and three 20-minute telephone sessions, delivered by a Triple P practitioner.

What happens during the intervention?

Each parent receives a workbook summarising the session content with suggestions for between-session tasks. Parent learning is further reinforced through presentations, group discussion, DVDs, live demonstrations of parenting skills, role-play, peer modelling, and small-group problem-solving exercises. Parents also receive four individual telephone consultations with the practitioner to update the practitioner on their family’s progress and discuss any issues.

Who can deliver it?

Practitioners with experience and qualifications in a helping profession, including dieticians, physical education teachers, nurses, psychologists, and physicians.

What are the training requirements?

Practitioners attend two days’ training, one day pre-accreditation workshop, and a half-day accreditation session. It is recommended that they spend four to six hours on individual preparation before accreditation. Booster training of practitioners is not required.

How are the practitioners supervised?

It is recommended that practitioners are supervised by one host agency supervisor. Supervisors do not have intervention training.

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.

A quality assurance checklist is available for organisations to use when planning for quality assurance of Triple P. There are three standard fidelity protocols built into the Triple P Implementation Framework: (1) Practitioner Accreditation, (2) Intervention Fidelity using Session Checklists, (3) Supervision and Practitioner Support Standards using the Peer Support Network. Triple P UK offers trainer facilitated PASS sessions or a Flexibility & Fidelity workshop for professional development.

Is there a licensing requirement?

No

Group Lifestyle Triple P’s most rigorous evidence comes from a single RCT conducted in Australia consistent with Foundations’ Level 2 evidence strength criteria.

This study observed statistically significant improvements in Group Lifestyle Triple P children’s weight (through body mass index measurements) and parent reports of problematic weight related behaviour in comparison to families not attending the Triple P group. Group Lifestyle Triple P parents were also significantly more likely to report increased parenting self-efficacy and reduced ineffective parenting behaviours compared to parents not attending the intervention.

Group Lifestyle Triple P has preliminary evidence of improving a child outcome, but we cannot be confident that the intervention caused the improvement.

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.
