Description of intervention(s) / exposure
Acceptance and Commitment Therapy group-based manualised therapy program delivered by school counsellors formally trained in Proactive, at the child's school, as 10 x 1 hour sessions over 10 weeks, involving up to 8 children. Parents will have limited involvement. They will receive 2 sessions of 1. 5 hours duration coinciding with session 2 and session 7. The first session will be run by the school counsellors (psychologists trained in ProACTive who will be implementing the groups, using a Powerpoint presentation prepared by the CI. The first session involves psychoeducation around anxiety, ACT, and the ProACTive program. Parents receive a manual containing the information being presented in more detail. They will also have the opportunity to ask any questions relevant to their child's treatment. particular focus will be on parenting a child with anxiety, and how to ensure the skills being taught are generalised.. The 2nd session in week 7 will be conducted by the 2 CIs using a webinar format where parents across the various schools can interact live. Specific focus will be on understanding the upcoming exposure in-session activities, and how to assist with generalisation. It will also be an opportunity to clarify any questions about the skills taught thus far, as well as trouble shooting generally issues that may be applicable across families. Parents will be asked to submit their questions prior to the webinar.
The ACT program will involve the "Proactive" developed at The Children’s Hospital at Westmead, for children aged 7-11 years and 12-17 years, respectively. Groups will be run by 2 school counsellors who are psychologists formally trained in Proactive. Proactive has been empirically evaluated and found to be an effective treatment for children and young people with anxiety. This program incorporates all six ACT core therapeutic processes that target psychopathology including Acceptance, Being Present/Mindfulness, Valued directions, Committed Action, Self-as-context and Cognitive Defusion. Rather than focusing on symptom control, this program will concentrate on anxiety management via supporting children to identify what is important to them and get on with doing what they enjoy and is important to them, whilst encouraging acceptance of anxious thoughts and feelings that may arise in the process of doing so. Sessions involve Formal mindfulness practice is incorporated on commencement of each session. Psychoeducation (sessions 1and2) includes an adolescent-adapted explanation of the ACT model via metaphor and experiential learning approaches. Values cards support understanding of the concept of living a valued life(session2). Defusion (getting some distance from difficult internal experiences) is taught via metaphors and experiential exercises (session 3 onwards). Graded exposure is undertaken using the ACT model whereby the act of confronting the fear is an exercise designed to enhance psychological flexibility, while the therapeutic procedure is what is performed in the presence of the feared situation . Specifically, emphasis is placed on supporting mindful observation and acceptance of anxiety while faced with fear in order to foster committed action in line with self-identified values (from session 4 onwards). Finally, problem solving and social skills are incorporated to facilitate
committed action. The skill of self-compassion is specifically addressed during acceptance psycho-education and in the final session where mindfulness activities using loving kindness are demonstrated.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following referral to the Department of Psychological Medicine, The Children's Hospital at Westmead (CHW) the parents/carers of potential child participants are briefly screened over the phone to determine suitability for baseline assessment using a checklist developed for this study. If deemed suitable at this point, they will be sent an information pack about the study including consent forms, and a battery of questionnaires to be completed by both the child and parent as part of the baseline assessment. Eligible participants and their parents/caregivers will be randomised to one of two conditions, Acceptance and Commitment Therapy (ACT), or a waitlist control group for a period of 10 weeks.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
This is a block randomised controlled trial, with the participant serving as the unit of randomisation. Randomisation will be undertaken via a freely available computer random assignment software application, ‘Graphpad’ (for more information and to access see: www.graphpad.com/quickcalcs/randomize2.cfm). The researchers conducting baseline assessments will be blinded to the treatment type to reduce potential bias and will only become aware of the group allocation upon commencement of the relevant program. The researcher who determined if a participant was eligible for inclusion in the trial was blind to the group allocation process, at the time of allocation. Allocation was performed at a central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A blocked randomised list will be created using computer software (i.e. computerised sequence generation) available at https://www.sealedenvelope.com/simple-randomiser/v1/lists

Statistical methods / analysis
All analyses will be conducted on both an intention to treat basis, with participants’ data analysed according to the group to which they were randomized, and completers. For the ITT data from any participants who fail to complete the therapy program will be treated conservatively, with LOCF used. If completer and ITT outcomes are similar, ITT outcomes will be presented only. The main statistical analyses will be a series of mixed model analyses. The first factor, Group, will have two levels (ACT versus Controls). The second factor, Time, is a within subjects, repeated measures factor. Two sets of linear mixed model analyses will be conducted examining the following outcomes: (1) Anxiety: PARS, SCAS (2) Quality of Life: CALIS. The mixed model approach has been selected as it allows for inter-participant and intra-participant variance as well as the inclusion of participants with missing data, whilst maintaining power. The same design used for this study was used by Wuthrich et al (2012), and they used a mixed model approach. We also used this approach for our initial RCT .
Descriptive statistics will be used to score school counselor ratings of feasibility questions, rated on a 5 point Likert scale
