Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is a psychological therapy called Collaborative & Proactive Solutions. It will be delivered by study trained clinicians. The intervention comprises 8x1 hour sessions once a week for six weeks and then once every two weeks for the final 2 sessions (total of 8 sessions over 10 weeks).
The intervention is administered face-to-face, or via telehealth, with the child and parent/s. Sessions can include time with the parent/s alone, with the child alone, and with both the child and parent/s present. The structure of the intervention is as follows:
(a) Identification of lagging skills and unsolved problems that contribute to temper outbursts, and a discussion of how existing parental responses may be counterproductive;
(b) Prioritization—helping parents prioritize which unsolved problems will be the focal point of initial problem-solving discussions;
(c) Introduction of the Plans framework— helping parents understand the three potential responses to solving problems: Plan A (solving a problem unilaterally, through imposition of adult will and often accompanied by adult-imposed consequences), Plan B (solving a problem collaboratively and proactively), and Plan C (setting aside the problem for now); and
(d) Implementing Plan B—helping parents and children become proficient in the use of Plan B and largely discontinuing the use of Plan A.
Although the clinician actively guides the problem-solving process initially, the goal of treatment is to help the child and parents become increasingly independent in solving problems together.
Clinicians will complete a Clinical Record Form (CRF) for each session to document adherence to intervention protocols.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be concealed. An independent statistician will pre-generate a random number sequence which contains the randomisation sequence number and the group allocated (control vs intervention), and upload it to the study database which will assign participants once they are enrolled in the database.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomisation schedule will be generated using block randomisation with variable block sizes by an independent statistician at the Clinical Epidemiology and Biostatistics Unit at the Murdoch Childrens Research Institute. Randomisation will be stratified by sex and age (5-11 or 12-15) to ensure similar proportions of males and females, and children and adolescents across arms

Efficacy
Statistical methods / analysis
In our pilot study, we found an effect size of 0.5 between the CPS and usual care groups. In order to provide 80% power to detect this clinically meaningful difference, using a two-sided test with alpha = 0.05, we need to enrol 64 children in each arm. Given there is typically a dropout rate of approximately 20% in trials such as this we will inflate our sample size to account for this, thus we aim to recruit a total of 160 children (80 children in each group).

Analyses will be conducted according to the intention-to-treat principle with participants analysed according to the intervention they were allocated to irrespective of what or how much intervention was received. If there is <5% missing data in the primary and key secondary outcomes, analysis will be conducted using a complete case analysis. If there is more missing data, the missingness will be explored, and if there is evidence that the data are missing at random then analysis will be conducted using multiple imputation to handle the missing data. The primary outcome, reduction of irritability on the CL-ARI, will be compared between the groups using mixed effects linear regression adjusted for sex and age (6-11 versus 12+ years) as used in randomisation. Results will be reported as an (adjusted) mean difference, 95% confidence interval and the corresponding p-value. Secondary outcomes will be compared between the groups using mixed effects linear (continuous outcomes) and logistic (binary outcomes) regression adjusted for sex and age, with results reported as (adjusted) mean differences and odds ratios, respectively, along with 95% confidence intervals and the corresponding p-values.

Summary
Brief summary
Irritability is a highly prevalent, transdiagnostic symptom present in many commonly diagnosed child mental health disorders that confers risk for future anxiety, depression, and suicidality. Approximately 30-50% of children referred to mental health services experience severe irritability and irritable children place a high burden on the healthcare system with up to 15 times more service usage than children with mental health problems who are not experiencing irritability. There are currently no evidence-based treatments available that effectively reduce irritability and associated impairments.
We will conduct a randomised controlled trial to test the efficacy of a psychological intervention, Collaborative and Proactive Solutions, for irritability in children and adolescents aged 5-15 years compared with usual care in terms of reducing irritability, and improving broader child and family wellbeing.
Children referred to outpatient and community mental health services will be assessed for clinically significant irritability. Eligible children will be randomised to the CPS intervention (n=80) (8 sessions over 10 weeks) or usual clinical care from the mental health service (n=80). All participants will be assessed 4 and 12 months post-randomisation.
