Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention consists of one, 2-hour parenting discussion group on Managing Fighting and Aggression, designed to target the direct and indirect pathways of parenting impact on sibling conflict outcomes (i.e., parenting practices, and parenting confidence and stress). The Managing Fighting and Aggression discussion group targets parents of children with sibling conflict and is designed to assist parents in preventing and managing their children’s conflict effectively. The discussion group aims to combine education about conflict management with parenting strategies that will empower parents to ensure their children are implementing prevention and management plans appropriately (using checklists, charts, and diary keeping to track children’s progress).

Participants will be asked to complete a series of online measures on entry to the trial, four to six weeks later and at a 6-month follow up.

Behaviour
Comparator / control treatment
Families in care-as-usual will also be assessed on entry to the trial, four to six weeks later and again at six months. During this time, families will continue to undertake whatever practices they were previously using in attempting to manage their children’s conflict. After the 6-month follow-up assessment, families will be offered participation in the intervention.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following eligibility screening and completion of the pre-assessment measures, randomisation to condition will occur. Participants will be randomly allocated to either the intervention condition or care-as-usual condition using a computer random number generator. Allocation concealment will involve contacting the holder of the allocation schedule who is “off-site” or at a central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a table created by computer software. Depending on recruitment rates, parents may be randomised in a block sequence (i.e., 15 parents randomised concurrently) The experimenter will be blind to the process of randomisation.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?

Other design features
Participants in the Intervention condition receive the intervention after completing the pre-assessment measures. Participants in the care-as-usual condition will receive the intervention at the completion of the trial.

Efficacy
Statistical methods / analysis
A power analysis was conducted to determine the required sample size. To detect a medium effect size of .50, with alpha of .05, and power at .80, a minimum of 50 participants per cell is required (N = 100 for the two-group study).

ANOVA and MANOVA methods will be used to evaluate the data across the timepoints and between the conditions.
