Description of intervention(s) / exposure
The Standard duration parenting intervention is the 8 session Group Triple P Program. This behavioural family intervention involves 2-hour group sessions held once a week for four weeks, followed by 20-minute individual telephone sessions, also once a week for four weeks. The four group sessions focus on the following topics: positive parenting, helping children develop, managing misbehaviour and planning ahead for high risk situations. These four sessions cover 17 core positive parenting strategies. The group program involves active skills training to teach parents these key parenting strategies, including videotaped modelling of skills, roleplay, rehearsal and feedback. The group sessions are followed by telephone discussions to assist parents to implement the skills learnt in the program. This intervention will be facilitated by a registered psychologist who is also an accredited Triple P Practitioner.

The brief duration parenting intervention is the Triple P Parent Discussion Group focussing specifically on how to manage fighting and aggression. This intervention involves a single two-hour group session followed by 20-minute telephone sessions, held once a week for two weeks. The group session covers 8 positive parenting strategies and involves videotaped modelling of key parenting skills and some roleplay, but does not include the extensive roleplay, rehearsal and feedback of the standard duration intervention. This intervention will be facilitated by the same registered psychologist and Triple P Practitioner as for the standard intervention.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocation is concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Families are randomly assigned to one of three conditions using the next sequential opaque envelope technique (Doig & Simpson, 2005). The method of sequence generation was simple randomisation using a randomisation table.
Masking / blinding
Open (masking not used)

Analysis of covariance and multivariate analyses of covariance
A power calculation was conducted using G*Power 3.1 (Faul, Erdfelder, Lang & Buchner, 2007). A sample size of 72 families (24 per group) was estimated to be sufficient to detect a large effect size for 3 group analysis of variance (power=0.80; alpha = 0.05).

Summary
Brief summary
This randomized controlled trial compared the efficacy of a brief parenting intervention with a standard parenting intervention and a waitlist control group, for reducing toddler aggressive behaviour, dysfunctional parenting and related aspects of family functioning. It was hypothesized that both interventions would show superior improvements relative to the control group in child aggressive behaviours and other child and family outcomes, but that the brief and standard interventions would not differ significantly from one another at post-assessment or 6-month follow-up.
