Primary study design	Interventional
Study design	Cluster-randomised indicated prevention trial
Secondary study design	Randomised controlled trial
Study type	Participant information sheet
Scientific title	Efficacy or indicated prevention in children with deviant externalising behaviour aged 3 to 6: a cluster-randomised indicated prevention trial
Study acronym	PEP
Study objectives	1. Reduction of externalising symptoms assessed by parents and kindergarten teachers 2. Improvement of parents' and teachers' educational behaviour 3. Reduction of parental stress 4. Long-term stability of these effects
Ethics approval(s)	Ethics Committee of the German Research Foundation approved on the 7th November 2000
Health condition(s) or problem(s) studied	Externalising behaviour (symptoms of attention deficit hyperactivity disorder [ADHD], oppositional defiant disorder [ODD], aggression)
Intervention	PEP consists of 10 sessions (90 to 120 minutes each) and a constituting session. Minimum time between two sessions was 1 week. Therefore after the pre-test period (4 months, including home visits at each family) the training period took 3 to 4 months depending on holidays and external reasons for each groups' schedule. Appointments for post test in both arms were planned just after the last session of PEP within the intervention group. Follow ups were carried out via questionnaires only and via mail 1 year after pre-test. Therefore the interval between the timepoints was about six months for each family. The trial was carried out in 2 waves.
