Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Random allocation occurs in a central office by research staff who are not involved in participant assessment or program delivery . Allocation is kept in a sealed envelope and concealed from couples, the researcher determing study eligibility, and midwife educators until all assessment information is returned and the couple meets eligibility criteria. After that point allocation concealement is no longer possible as one condition is a couple based education porgam and the other a woman only education condition.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A coin toss determines the allocation for a couple (heads = intervention), and the next couple who returns their assessment receives the opposite allocation. This ensures that equal numbers of couples are assignment to the intervention and control. The coin toss procedure is repeated until all couples are assigned.
