Plain English Summary

Background and study aims
The main symptoms of attention deficit hyperactivity disorder (ADHD) are inattention, overactivity and impulsiveness. The UK National Institute for Health and Clinical Excellence (NICE) estimated that in 2008 about 210,000 children aged 5-18 years are affected by ADHD in England and Wales. Children and young people with ADHD suffer a wide range of issues that can have a negative impact on their everyday life, family, education and future prospects. There is now an increasing number of children, particulary preschool aged children, attending medical, social and education services for behaviour problems related to this disorder. The personal, social, and financial burden to families and their child with ADHD can be significant and the cost to society of ADHD is high and growing.

Treatment for ADHD generally begins during the school years. Medication is a recommended and effective treatment for older children and adults but parents often have concerns about the use of medication for the control of behaviour in younger children. However, parenting programmes have been recommended for the treatment of behaviour problems. A number of such programmes have been designed particularly to treat behaviour problems in children but have not been developed to tackle the core symptoms of ADHD such as inattention, overactivity and impulsiveness. Children with ADHD may also have other difficulties such as learning or speech and language difficulties and ideally parenting programmes should be adapted to deal with these complications too.

The aim of this study is to decide which of two parenting programmes works best to help children with preschool-type ADHD problems. These programmes are:
1. The Incredible Years (IY), a group-based programme for parents which is carried out in the community, e.g. in a local hall
2. The New Forest Parenting Programme (NFPP) which is carried out with the parent in their own home.

IY has been designed to deal with general behaviour problems in children but has also shown some success in the treatment of children with ADHD behaviours. The NFPP has been designed specifically to tackle the core symptoms of ADHD and other co-occurring difficulties in children. In the current trial both programmes will be 12 weeks long with one session of between 1 and 2 hours every week.

Who can participate?
The parent / main caregiver (18 years of age or over) and their preschool child aged 2 years 9 months to 4 years 6 months who has significant problems with overactive or hyperactive behaviour. We will ask you to complete some questionnaires and assessments to see if you and your family would benefit from participating in a parenting programme.

What does the study involve?
If the child is eligible and agrees to take part in this study, we will ask them either to take part in one of the 12 week parenting programmes which will begin within the following few weeks or we will ask you to continue for 12 weeks as normal receiving the usual type of help and advice in the community. If we ask them to continue as normal then after the 12 weeks they will be asked if they would still like to undertake the parenting programme. So whichever group they are in they will eventually receive a parenting programme, if they wish. They will be free to withdraw from the research at any time, without giving a reason.

Before the start of the programme and after it has finished a researcher will visit the family in their home and ask them to complete a number of questionnaires and assessments measuring ADHD symptoms and other aspects of the child’s behaviour and the mother’s mental health. This will take about 1 and a half hours of your time. We will also be asking some parents if we can come back 6 months after that second visit in order to complete some further questionnaires. A therapist will also arrange a visit to their home before the start of the programme. During the programme, parents will complete 3 questionnaires each week for 6 weeks. Parenting sessions will be audio- or video-recorded for the purpose of therapist training and supervision.

At some point in this period we will also arrange to collect a saliva sample for DNA. This will help us to see if genetic make-up alters how useful parenting programmes may be for parents and their children.

What are the possible benefits and risks of participating?
It is hoped that the parent or main caregiver will enjoy taking part in a parenting programme and that this will be of benefit to their child with preschool ADHD type problems and to the family in general. We do not feel that any risks are involved in participating in this study which has been approved by the South Central Portsmouth Research Ethics Committee.

Where is the study run from?
The study is being carried out by researchers in four centres across the UK, in Southampton, North Staffordshire, Nottingham and Dundee. We can only enlist parents to the research if they live fairly local to the research centre in each of these areas.

When is the study starting and how long is it expected to run for?
Enlistment of parents/main caregivers to the study will commence in February/March 2012 and the first block of parenting programmes will start in April 2012. We will carry out five block of 12 week parenting programmes over the next 30 months. We hope to enlist more than 300 parent/main caregivers in total across the four centres. Groups of parents will take part in the NFPP and IY programmes which will run alongside each other in these 12 week blocks.

Who is funding the study?
National Institute for Health Research who oversee research in the NHS in the UK.

Study information

Scientific title

A multicentre randomised controlled trial comparing the efficacy of a specialist and a generic parenting programme for the treatment of preschool ADHD.



Study hypothesis

Attention Deficit Hyperactivity Disorder (ADHD) is estimated to affect between 3 to 5% of the school aged population. The goal of the programme of which this study is a part is to develop a programme for early detection and intervention for ADHD (PEDIA). In this study a new enhanced version of the New Forest Parenting Package (NFPP) will be used. The trial will assess the effectiveness and cost effectiveness of e-NFPP relative to a generic group based parent training approach recommended as cost effective by NICE - Incredible Years.
