The researcher will be blinded to the allocation of respondents up until discharge/referral on from BIS for FT patients or at the end of the waiting period for CC patients. This will be achieved by the researcher conducting study recruitment & collecting baseline measures before instructing a third party (local clinical trials' nurse) to conduct randomisation & reporting of allocation (to the patient & BIS) using a random sequence of opaque envelopes previously generated by a statistician independent of BIS. Subsequently, all data will be handled using study identity numbers; group allocation identifiers will only be added at analysis. This model was used successfully in the Phase II pilot trial.
