EIF Programme Assessment

Evidence rating

Level 4 Standard Teen Triple P has preliminary evidence of improving a child outcome, but we cannot be confident that the programme caused the improvement.

What does the evidence rating mean?

Level 2 indicates that the programme has evidence of improving a child outcome from a study involving at least 20 participants, representing 60% of the sample, using validated instruments. 

This programme does not receive a rating of 3 as its best evidence is not from a rigorously conducted RCT or QED evaluation.

Cost rating

A rating of 2 indicates that a programme has a medium-low cost to set up and deliver, compared with other interventions reviewed by EIF. This is equivalent to an estimated unit cost of £100–£499.

Child outcomes

According to the best available evidence for this programme's impact, it can achieve the following positive outcomes for children:

Level 4 Standard Teen Triple P

About the programme

What happens during delivery?

How is it delivered?
  • Standard Teen Triple P is delivered by an individual therapist to parents, over 10 one-to-one weekly sessions that last approximately one hour each.
    • NB: Where applicable, both parents are invited to attend the sessions. Teenagers are also encouraged to attend some of the sessions, however, their attendance is not essential.
What happens during the intervention?
  • Standard Teen Triple P involves a thorough assessment of the parent-child relationship, and the application of parenting skills to a broad range of target behaviours.
  • Practitioners use a range of learning methods, including behavioural rehearsal to teach parents new skills, guided participation to discuss assessment findings, active skills training methods to facilitate the acquisition of new parenting routines, and generalisation-enhancement strategies to promote parental autonomy. In addition, parents are continuously provided with constructive feedback and are encouraged to set goals, practice strategies, and complete their activity workbook and homework tasks.
  • The first three sessions are set-aside for assessment. In session 1, parents are interviewed to obtain information regarding the current problem, the teenager’s developmental history and the family history. If possible, session 2 involves an interview with the teenager and an observation of the parent-child interaction. Then, in session 3, the practitioner shares assessment findings and assists the parent(s) to set goals.
  • The next sessions are focussed on the actual intervention, whereby each session of active training (sessions 4, 6, and 8) are followed by practice sessions (sessions 5, 7, and 9). Sessions 4-5 cover promoting appropriate behaviour, sessions 6-7 are for managing problematic behaviour, and sessions 8-9 are on dealing with risky behaviour.
  • The intervention ends with session 10, which covers additional skills to facilitate generalisation and maintenance of treatment gains.

What are the implementation requirements?

Who can deliver it?
  • The practitioner who delivers this programme can come from a range of professions (e.g. school counsellor, nurse, psychologist, social worker, or allied health professional), but must have a minimum recommended QCF level 4/5.
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 2-hour sessions, by one practitioner with a minimum QCF level 7/8.
  • 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 programme. 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?

Programme fidelity is maintained through the following processes:

  • Training manual
  • Other printed and 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?

There is no licence required to run this programme.

How does it work? (Theory of Change)

How does it work?
  • Standard Teen Triple P Teen assumes that some parenting practices unintentionally reinforce teenage risk taking and emotional problems. The programme, therefore, helps parents identify parenting practices that may unintentionally reinforce risky and problematic teenage behaviour.
  • Parents also learn strategies for effectively communicating with their teenager, monitoring their teenage child’s activities and supporting their teenager’s independence.
  • In the short term, it is expected that the teenage child will become more respective of his or her parents, engage in less risky behaviour and make more positive decisions for him or herself.
  • In the longer term, the teenager will be less likely to engage in antisocial behaviour and substance misuse, and will be more likely to achieve better in school.
Intended outcomes

Supporting children's mental health and wellbeing
Preventing child maltreatment
Enhancing school achievement & employment
Preventing crime, violence and antisocial behaviour
Preventing substance abuse
Preventing risky sexual behaviour & teen pregnancy

Study design and sample

This study is a comparison group study, which involved allocating parents to a Standard Teen Triple P intervention group or a wait-list control group.

Using standard methods of randomization was not practical in this study. Therefore, all eligible families recruited from April to August 2007 were assigned to the intervention group, and all families recruited after this period, from September to December 2007, were assigned to the wait-list control group. Recruitment was stopped from December onwards and restarted in June 2008 up until August 2008, at which point all eligible families were randomly allocated to each condition. 

The study was conducted in Australia with a sample of 58 families, who had a child aged between 11-16 years (mean = 12.92 years) experiencing detectable behavioural and emotional problems. The population was a motivated sample of parents who had concerns about their child’s behaviour and had scored the child in the elevated range of the Strengths and Difficulties Questionnaire. 

The majority of children were either Australian or European (93.5%), and there were more females in the control group (62.1%) as compared to the intervention group (30.3%). Most parents had been educated to tertiary level (mothers: 75.8%; father: 79.2%) and were employed outside the home (mothers: 80.6%; father: 97.9%). In addition, 75.8% of families were two-parent families with an average of two children living at home (mean = 2.45 children), and with over half the sample (53.1%) receiving an annual income of more than AUD$ 75,000.


  • Child behaviour (including emotional symptoms, conduct problems, hyperactivity, peer relationship problems, prosocial behaviour, and total behavioural difficulties) was assessed using the Strengths and Difficulties Questionnaire (parent report). 
  • Communication and conflict in the parent-adolescent relationship was assessed using the Conflict Behaviour Questionnaire (parent report).
  • Parental discipline practices (including laxness and overreactivity) were measured using the Adolescent Parenting Scale (parent report).
  • Interparental conflict over child rearing (including parents’ ability to cooperate and work together, the extent to which parents disagree over rules and discipline for child misbehaviour, the amount of open conflict over childrearing issues, and the extent to which parents undermine each other’s relationship with their children) was measured using the Parent Problem Checklist (parent report).
  • Marital or relationship quality and satisfaction was assessed using the Relationship Quality Index (parent report).
  • Parental mental health and wellbeing (including parental levels of depression, anxiety and stress) were measured using the 21-Item Depression, Anxiety, and Stress Scale (parent report).


This study identified statistically significant positive impact on a number of child and parent outcomes, including:

  • Child’s behavioural difficulties (Strengths and Difficulties Questionnaire)
  • Parent-adolescent conflict (Conflict Behaviour Questionnaire)
  • Parental overreactivity (Parenting Scale).
