Comparator / control treatment
A delayed treatment/wait-list control will be used.

The 8-weeks of no treatment will serve as the control.

Allocation to intervention
Randomised controlled trial
Query!
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.
