Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants recruited from sleep clinics at the Royal Prince Alfred and Royal North Shore Hospitals, individuals who have been diagnosed with OSA following polysomnography and who have elected to undergo CPAP treatment will be invited to take part in the present study.
Consenting participants were randomised to in hospital CPAP titration or home autoCPAP titration. Allocation was concealed using sealed opaque envelopes which were opened following participant consent and prior to treatment as usual session.
Following treatment as usual for CPAP participants were randomised to CBT or Social Reciprocity (SR). Sealed opaque envelopes containing treatment allocation were opened following completion of treatment as usual.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
There are two randomisation components in this study. Both sequences are permuted block randomisation from a web based sequence programme.
Masking / blinding
