Study type
Description of intervention(s) / exposure
BRAVE is an online cognitive behavioural therapy (CBT) programme for children and adolescents with anxiety and has two versions: one for children aged 7-12 and another for adolescents aged 13 plus years. The two versions of the programme are age-appropriate and designed to meet the developmental and cognitive level of younger children or adolescents. BRAVE is delivered by internet at home to the child and parent. BRAVE consists of ten 1-hour child sessions, 5 (in adolescent version) or 6 (child version) parent sessions and two booster sessions. Information is presented through interactive exercises, text, colourful graphics, animation, quizzes, and games. To avoid activities being skipped, most exercises require a response before the next screen can be accessed. Homework exercises are set at the end of each session. If a child or young person misses a session, the system sends out automatic reminders. The sessions are designed to be completed sequentially at weekly intervals (the next available session becomes accessible seven days after the previous one is completed). The therapist (BRAVE trainer) sends weekly emails to the child and their parents, with encouragement and feedback based on the interactive exercises. The therapist also phones the family to assist them to complete an exposure hierarchy around session 5 which takes approximately 15-30 minutes

Brief summary
The aim of this study is to trial BRAVE, an online computerised cognitive behavioural therapy (CCBT) programme for children and adolescents with anxiety in Canterbury following the earthquakes.
BRAVE is an innovative programme for the treatment of anxiety in children and adolescents and it was found efficacious in Australian trials and in our pilot study of 32 families. The aim of this follow on study was to assess feasibility, utility and effectiveness within primary care,

We will conduct an open trial of BRAVE while funding is provided from the CDHB , Commencing 2014 and ended 2018 . All evaluation is done online and change will be measured using our primary outcome of the CAS8, (a short form anxiety questionnaire based on the SCAS.. We will measure the extent of change in the CAS8 (parent and child version) along with uptake and feasibility of programme delivery data.

Results – basic reporting
Results – plain English summary
Following a major natural disaster in NZ, an online therapist assisted CBT programme for children with anxiety, (BRAVE_TA ) was made available in primary care.
Methods Uptake and feasibility of BRAVE_TA delivery was assessed by examining referral patterns, non-engagement rates and programme progression within a geographic region of NZ (Canterbury population of around 500,000). Effectiveness of BRAVE_TA was measured by the extent of change in the primary outcome measure of anxiety, the CAS8, between baseline and last completed session.
Results There were 1361 referrals to BRAVE_TA over 2014-2018, mostly from primary care doctors and nurses in primary schools. After attrition due to triage and family withdrawal,
75 % (N=1026) were enrolled. Around half of children/adolescents completed 4 sessions. Children/adolescents who completed more sessions, had lower anxiety after their last session, with most of the improvement occurring within the first three to four sessions.
Interpretation BRAVE_TA has shown to be an acceptable and effective ‘e’ therapy tool in a ‘real world’ primary care setting for children/adolescents with anxiety.
