Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Condition 1: 10 sessions of CBT over 12 weeks + 12 week trial of Sertraline Hydrochloride concurrently

Condition 2: 10 session of CBT over 12 weeks + 12 week trial of placebo medication concurrently

CBT sessions include psychoeducation about anxiety, and skills to manage anxiety. Skills focus on thinking styles and behavioural responses to anxiety. Sessions include both children and parents (less parental involvement for adolescents) and are delivered individually (to each family). 10 sessions are delivered weekly, except for week 9 and 11 where there is a break from CBT sessions. Sessions are approximately 50 minutes in duration.

Sertraline Hydrochloride is administered at dosages ranging from 25 - 200mg - starting with small dosage and being titrated up to a level for maximum tolerance and treatment effects. Administration is via oral capsule and adherence will be monitored via medication diary and pill counts.

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)
Participants self-refer to the clinic or research team, are sent information about the research trial, complete a brief telephone screen and if determined to meeting inclusion but not exclusion criteria from this discussion are sent the treatment consent form and booked in for a diagnostic assessment and complete an online questionnaire battery. Suitability is determined from the diagnostic interview and if suitable participants make payment for treatment and are then randomly allocated to medication condition and booked in for their treatment sessions/appointments. Allocation to condition involves contacting the holder of the allocation schedule who is located at a separate centre (the Pharmacy) and is not involved in assessment or treatment of participants.

Efficacy
Statistical methods / analysis
Analyses will be conducted using intention-to-treat and completer models. Multiple imputation will be used to impute missing data. Categorical data will be analysed via chi-squared tests, and continuous data with parametric or equivalent non-parametric tests including mixed linear models.

A sample of 200 participants (100 to each condition) will detect differences in expected improvement for CBT+SSRI of 80% and for CBT+placebo of 60% with power of .8 and significance level of 0.05. Additional participants will need to be recruited in order to achieve 200 participants being randomised to treatment.
