Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The hospital files of pregnant women who were to make their first visit to the antenatal clinic at the hospital were checked by the researcher, and all eligible women were given information and consent forms by the antenatal clinic receptionists upon registration at the clinic reception desk. The researcher then approached these women individually and asked if they would take part in the study, if necessary reading the letter to them or providing further explanation. Women who did not wish to participate were thanked for reading the letter and were not made to feel uncomfortable about their refusal. Those who signed the consent forms were given a numbered, opaque envelope to open that contained a letter informing them that they were, or were not to be interviewed. Consent forms were noted with ‘intervention’ or ‘control’ and the number of the envelope, and were filed in the patients’ hospital notes.

Women allocated to the control group were thanked for their participation and assured that their baby’s birth details would be of importance to the study. The researcher explained to intervention group women that she would be talking to them about pregnancy and that she would find them after their ultrasound scans, while they were waiting to see the doctor. Women randomised to the intervention group were duly identified and collected from the waiting area of the antenatal clinic following ultrasound scans but before seeing the consultant.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Women agreeing to participate were randomised either to standard antenatal care plus a discussion or to standard antenatal care only. Letters allocating women to either intervention (I) or control (C) groups were placed in opaque sealed envelopes by someone unconnected with the trial. The envelopes were numbered consecutively in accordance with lists of randomly created blocks of 5, using the throw of a die, producing allocation sequences such as ICICI or IICIC. The 3:2 randomisation was chosen to maximise the researchers' time for interviewing in clinic.
