Description of intervention(s) / exposure
Two active treatments are compared: Collaborative and Proactive Solutions (CPS) vs Parent Management Training (PMT) for the treatment of oppositional defiant disorder in youth.

160 youth, aged 7-14 years were randomised to one of the active conditions.

Treatments were delivered face-to-face up to 16 x 1 hour sessions, once a week for 16 weeks. Treatment was delivered to individual families only. Both parent/s and child attended each session. Treatment was delivered in a urban community-based psychology clinic. Following treatment families were offered 5 monthly booster sessions by phone to consolidate sessions. In these booster sessions parents reported how they were progressing and troubleshot any behaviour problems. The therapist then advised how to use previously taught skills in these situations. Phone calls ranged from 2-15 minutes. Families were advised of the option to access boosters, but they were optional.

Collaborative and Proactive Solutions is a cognitive behavioural model developed by Dr Ross Greene. The CPS model posits that challenging behaviours occur when a child's skills do not match the demands of the given situation eg., flexibility, transitioning, maintaining focus. CPS treatment focuses on helping parents identify their child’s lagging skills and reframe their perception of their child’s behavior using this conceptualization (Greene, 1998). From there, the parent(s) and young person identify current “unsolved problems” and are coached in steps to solve the problems collaboratively and proactively. CPS entails four treatment modules (a) psychoeducation and identification of unsolved problems, which explains the conceptualization of CPS and identifies the unsolved problems precipitating challenging behavior; (b) prioritizing unsolved problems based on their relationship to safety, gravity, or frequency; (c) learning about Plan A, B, and C and the concept that parents have a choice of how to respond to an unsolved problem; and (d) clinician modeling and coaching the use of Plan B to help parents and children solve problems together proactively. Plan A is parents responding to challenging behaviors in a unilateral manner. Plan B is parent and child collaborating to come up with a solution for the problem that preempts the challenging behaviour, and Plan C is putting aside expectations they have of the child to meet certain expectations. The CPS materials can be accessed via Dr Ross Greene. They can not be accessed from any other organisation.

Supplementary handouts were provided at the majority of sessions. They were already created and not created specifically for this study. Handouts for PMT are available in Barkeley's Defiant Child Manual. Handouts for CPS are readily available at: https://livesinthebalance.org/our-solution/#our-solution-overview

Treatment was delivered by experienced clinical psychologists (5 year plus experience) and graduate interns from a masters of Clinical Psychology program.

Training for therapists in both CPS and PMT conditions consisted of a one-day workshop, reading the manuals, listening to audiotapes of the entire course of treatment for 3 previous clients (approximately 40 hours), and 1-2 hours of weekly clinical supervision (dosage was matched for PMT and CPS).

Adherence to the allocated therapeutic model was assessed by having an independent rater, experienced in both therapies, code random audiotaped therapy sessions using the Session Content Analysis checklist (Ollendick et al., 2016). Independent raters, masked to the treatment being delivered, listened to an audio recording of a therapy session and then rated the presence or absence of treatment components on a 6-item scale. Each therapist also attended regular clinical supervision.

Comparator / control treatment
In this trial, Parent Management Training was utilised as an active control. We compared the effectiveness of an established treatment Parent Management Training (PMT) against an innovative treatment Collaborative and Proactive Solutions (CPS) for the treatment of oppositional defiant disorder in youth aged 7-14 years.

The PMT condition used a manualized program, Defiant Child (2nd ed., Barkley, 1997), which ordinarily comprises ten weekly 1-hour group sessions. PMT is a well-established, evidence-based therapy for targeting behavior problems based on behavioral and social learning principles (Barkley, 1997). The PMT program used in this study, modeled after that of Ollendick and colleagues (2016), was conducted with individual families with both parent and child present in parts of each session. The additions necessitated an extended timeframe (and can be accessed from Dr Rachael Murrihy). Barkley’s program comprised a number of core components, including (a) education regarding multifactorial causes of problem behaviors; (b) developing “positive attending” skills; (c) utilizing differential attending to increase compliance; (d) giving effective commands, (e) implementing home reward systems; (f) instruction in "time out" and response cost; and (g) use of a contingency system.

A combination of experienced clinical psychologists employed by the centre (5 plus years experience) and intern graduates from a Masters of Clinical Psychology program delivered treatment.

Treatments were delivered face-to-face up to 16 x 1 hour sessions, once a week for 16 weeks. Treatment was delivered to individual families only. Both parent/s and child attended each session. Treatment was delivered in a urban community-based psychology clinic. Following treatment families were offered 5 monthly booster sessions by phone to consolidate sessions.

Both treatments were manualised. Supplementary handouts were provided at the majority of sessions. The PMT treatment was based on Russell Barkley's Defiant Child Manual with minor modifications adopted from Ollendick et al.'s 2016 trial.

Adherence to the allocated therapeutic model was assessed by having an independent rater, experienced in both therapies, code random audiotaped therapy sessions using the Session Content Analysis checklist (Ollendick et al., 2016). Independent raters, masked to the treatment being delivered, listened to an audio recording of a therapy session and then rated the presence or absence of treatment components on a 6-item scale. Each therapist also attended regular clinical supervision.

Outcomes
Primary outcome [1] 328045 0
The Anxiety Disorders Interview Schedule for DSM-IV, Child and Parent Versions
Symptoms of oppositional defiant disorder as assessed by an independent rater conducting a structured interview with a parent/s using the Anxiety Disorders Interview Schedule (ADIS-IV-C/P; Silverman & Albano, 1996). For this study the primary outcome was the Clinician Severity Score (CSR) is CSR rating (0/8) taken from the Oppositional Defiant Disorder (ODD) component of the interview. ODD symptoms were based on the DSM-IV.

Secondary outcome [1] 397327 0
Disruptive Behavior Disorders Rating Scale
The DBDRS (Pelham et al., 1992) is a 41-item parent questionnaire developed to measure symptoms that reflect DSM-IV criteria for ODD. Parents scored each item on a 4-point scale ranging from 0 (never or rarely) to 3 (very often). Following Barkley’s guidelines, each item reaching the threshold score of two or higher is considered an endorsed symptom and recoded with a score of one. The secondary outcome is reaching four or more of the eight ODD items (in this case a diagnosis of ODD is suggested).

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Once determined eligible for the trial at the initial ADIS-IV-C/P assessment, families were randomly assigned by a central administrator, using a block randomization procedure (to ensure similar group size). The first family was randomly allocated to PMT or CPS via numbered containers, and subsequent families were then allocated using block randomisation.

Efficacy
Statistical methods / analysis
A power analysis was conducted using the simr R package (Green & MacLead, 2016) to test the difference between two independent group means using multilevel linear models, a medium effect size based on a previous clinical trial (d = .50), and an alpha of .05. Results showed that a total sample of 128 participants with two equal sized groups of n = 64 was required to achieve a power of .80. Assuming a 20% dropout rate, we aimed to recruit 80 participants per group.

To study the effects of treatment, the primary data analytic tool was Hierarchical Linear Growth Modelling, an advanced regression model for Windows (HLGM, Version 8; Raudenbush et al., 2019). HLGM was chosen to analyze continuous data because this technique allows for the modeling of intercepts and slopes where the treatment outcomes contain longitudinal data, and where observations are nested within individuals and are likely to have correlated error terms (Raudenbush et al., 2019). We estimated two sequential models. The unconditional model was initially undertaken, which examined symptom severity change across time, with separate analyses undertaken for both the DBDRS and the ADIS CSR. The unconditional model for each outcome measure was then compared to a predictor model, which included the addition of the intervention (CPS vs. PMT) and the covariates of sex and age to determine whether the full predictor model better fit the data.
In addition to traditional null hypothesis significance testing, which examines differences between conditions, equivalence testing was conducted to enable conclusions about group comparability (Rogers et al., 1993). A two one-sided t-test (TOST) examined whether differences between treatments were too small to be considered practically

Summary
Brief summary
The primary purpose of this study was to examine if participants in the Collaborative and Proactive Solutions and Parent Management Training groups, treated in a community setting, would exhibit significant improvement in ODD symptoms at post-treatment and 6-month follow-up. We were also investigating if improvement in the CPS group would be similar to outcomes in the PMT condition. This study featured components of efficacy studies (studies set in universities with stringent criteria) and effectiveness studies (studies set in community settings with experienced settings). We further expected that there would be no differences in treatment outcomes related to elements of efficacy and effectiveness design (Michelson et al., 2013). In all, it was intended that this study would strengthen conclusions reached about the effectiveness of CPS by reproducing earlier RCT's in a community setting in Sydney, Australia.
