Interventional
Description of intervention(s) / exposure
Intervention Condition: FAST-CBT
Parents randomised to the FAST-CBT group receive a login to the web portal: https://ocdbusters.griffith.edu.au/ which contains physical and informational materials. Specifically, a downloadable parent and child workbook which is aligned with the content of the 8 online modules. The web portal procedures, activities and processes are made up of an evaluation component (parent and child OCD symptom ratings and child-reported interference ratings, and parent-reported parental competence ratings), psycho-education about OCD, CBT with exposure-response prevention (ERP) techniques and homework to practice content learned. Homework activities will be a minimum of one exposure practice task per week (depending on task, this can take between 10 - 30 minutes to complete). The online modules and workbook content has been designed specifically for this study.

Group-based procedures, activities and processes include reflection, problem-solving and goal setting. Clinicians (i.e., provisional psychologists, general psychologists or clinical psychologists) with minimum Master of Clinical Psychology qualification and a minimum of 2 years experience will deliver the group sessions (60 minutes per session x4). The intervention is delivered to parents via a mix of online modules, workbook content and clinician facilitated group sessions via videoconference. The maximum number of participants per group is 6 (one clinician per group).

Groups occur once a week over four weeks. The online modules need to be completed between group sessions. There is anticipated to be between 10 - 15 groups over the 3 years of the trial, and the intervention occurs in the home.

The software for the web portal is able to capture parent progress and will alert the clinician if parents are falling behind with completion of modules, so that clinicians can check-in and help trouble-shoot any issues. Initial groups will be co-facilitated by clinicians who have been trained in the intervention and regular clinical meetings will occur to ensure intervention fidelity is maintained throughout the trial.

Statistical methods / analysis
Primary outcomes will be analysed using a mixed-effects linear regression model, with treatment included as the main effect, baseline OCD symptoms as the co-variable and patient included as a random effect. Secondary outcomes will be analysed using either linear (continuous), logistic (binary) or Poisson (count data) mixed-effects models using complete sample (following completion of intervention. An economic analysis overseen will evaluate the incremental cost-effectiveness of FAST-CBT from a health services and societal perspective.

Summary
Brief summary
The current study aims to conduct a nation-wide, RCT of the efficacy of the multi-technology intervention that trains parents to be ‘ERP coaches’ for their children via four self-directed web-based modules and videoconference group sessions with a therapist (i.e., FAST-CBT: Families Accessing online Skills Training in CBT) relative to Waitlist Control (WLC) for children (4-12 years) with subclinical and clinical OCD. Primary outcomes include symptom severity, OCD-related impairment, family accommodation and cost effectiveness, assessed at post-treatment (2 month following baseline) and at the primary end point 6 months following treatment (FAST-CBT condition only). Diagnostic status over time will be examined to determine intervention effects and the prevention of clinical diagnoses (for sub-clinical children) at 6 months follow-up. Secondary aims will be to explore predictors of treatment response, including child age, OCD severity, co-morbid symptoms (internalising and externalising), and family functioning (accommodation, parental depression/ anxiety/stress, parenting practices/family functioning). Based on the primary aims, it is hypothesised that relative to WLC, FAST-CBT will: (a) be associated with significantly greater reductions in OCD severity, OCD-related impairment, and family accommodation at post-treatment and follow-up; (b) will result in significantly fewer sub-clinical children at baseline converging into clinical range at post and follow-up.
