Scientific title


Study hypothesis

Hypothesis A:
New Forest Parent Training Project (NFPP) will be superior to treatment as usual (TAU) according to parent and teacher ratings of ADHD:
1. At the end of the experimental trial and
2. Over the ensuing 15 weeks
3. In addition, in follow-up (not funded by this grant) NFPP will be associated with delayed initiation of medication treatment and better transition to school

Hypothesis B:
Because NFPP targets oppositional behavior, as well as ADHD, we hypothesize:
1. That NFPP will result in significant reductions in Oppositional Defiant Disorder (ODD) symptoms compared to TAU at the end of the experimental trial
Because of its expected power to reduce ADHD, a known risk for the development of ODD, we hypothesize:
2. That NFPP will be superior to TAU in preventing the onset of ODD symptoms over two years (not funded by this grant)

Hypotheseis C:
NFPP will be associated with significantly more improvement in mothers’ ratings of their parenting satisfaction and efficacy and in all targeted parenting domains compared to TAU immediately after treatment.

Hypothesis D:
Changes in parenting will have positive mediating effects on children’s improvement in ADHD and ODD symptoms at the end of experimental treatment.

Ethics approval

At a meeting of the Health and Social Services Department's Ethical Committee (16/05/2005) it was agreed to approve the study.

Patient information sheet


Attention Deficit Hyperactivity Disorder (ADHD)


Children will be randomized in equal numbers to NFPP and the control condition.
The New Forest Parenting Package is a manualized treatment program for preschoolers with ADHD, which involves 8 weekly one hour sessions, delivered in the home by trained clinicians.
An Assessment and Referral Treatment as Usual (TAU) group is intended to control for the effects of time and to compare NFPP treatment effects with the potential impact of interventions provided by community-based practitioners on children’s and parents’ functioning during the course of treatment and follow-up.
Participants randomized to TAU will be assessed at the same time points and on the same measures as those randomized to NFPP. TAU participants will receive no treatment from study staff, nor will they be referred to specific contact. Rather, they will be given contact information for child mental health and related agencies (e.g. AACAP, APA [Psychology and Pediatrics Associations], CHADD etc.).

Participant inclusion criteria

The study will enroll young children who meet diagnostic criteria for ADHD.
At the first stage, children will be selected on the basis of scores of 20 or more on the Werry-Weiss-Peters-Hyperactivity Scale (WWP; Routh, 1978), which is a short pre-school hyperactivity screening measure. Parent’s views of the impact of the condition on children’s functioning will then be assessed (stage 2). Finally, children will have to score 18 or more on a pre-school version of the Parental Account of Childhood Symptoms (PACS; Taylor et al., 1991) interview.

Age group




Target number of participants

The study will enroll 150 medication naïve children.

Participant exclusion criteria

Excluded will be children with pervasive developmental disorder, psychosis, severe receptive language impairment, neurological disorders, or current history of child sexual or physical abuse. Parents will be excluded from the trial only if they are unable to fulfill the requirements for study participation (e.g. allow home visits, fluent in English).
