Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A referral letter addressed to children's medical practitioner containing information about, and a recommendation for, the 2018 Royal Australian and New Zealand College of Psychiatrists (RANZCP) guidelines for selective serotonin reuptake inhibitor (SSRI) medication as the follow-up treatment for children with anxiety disorders who do not respond to cognitive behavioural therapy (CBT). This letter will be given to children's parent/guardian after completion of the CBT course once the treating clinician has assessed the child and determined them to be a 'non-responder' to CBT. Parents/guardians will be informed to make and attend an appointment with their child's current treatment medical practitioner within the following 3 weeks to give the medical practitioner the referral letter. Adherence to the intervention, as well as issues concerning feasibility or acceptability (e.g., if parents were unable to get an appointment with their medical practitioner within the 3 week time allocation; if they did not want their child to be prescribed medication), will be measured through questionnaires that will be given to parents at the end of the testing phase, which will be 12 weeks after the referral letter has been delivered to treating medical practitioners.

Treatment: Other
Comparator / control treatment
A referral letter addressed to children's medical practitioner recommending continued practice of learnt CBT skills (treatment as usual). This letter will be given to children's parent/guardian after completion of the CBT course once the treating clinician has assessed the child and determined them to be a 'non-responder' to CBT. Parents/guardians will be informed to make and attend an appointment with their child's current treatment medical practitioner within the following 3 weeks to give the medical practitioner the referral letter. Adherence to the comparator treatment, as well as issues concerning feasibility or acceptability (e.g., if parents were unable to get an appointment with their medical practitioner within the 3 week time allocation; if they were dissatisfied with the course of follow-up treatment recommended by the medical practitioner), will be measured through questionnaires that will be given to parents at the end of the testing phase, which will be 12 weeks after the referral letter has been delivered to treating medical practitioners.
