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 will be recruited from a number of sources (eg, advertising, referrals from from health professionals etc) and assessed for suitability to participate in the study. Eligible participants will be randomised to either the CBT or Wait-list condition. A randomisation list will be computer generated by a person external to the study. The list will not be made available to the immediate research team during the recruitment and assessment process to limit any potential selection bias.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Block randomisation stratified by timing.
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
All participants will ultimately receive the same intervention throughout the study. However, those randomly allocated to the wait-list condition will receive treatment after a period of 8-weeks of no treatment.
