Allocation to intervention
Randomised controlled trial
Query!
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants screened by questionnaire and then invited to observational (laboratory) assessment. Eligible participants were not allocated to conditions until after inclusion in the trial - ie once criteria for inhibition of child and anxiety disorder in parent had been met. Hence initial inclusion in trial was independent of treatment allocation. Allocation to intervention was conducted by the study co-ordinator after assessment of participant eligibility by toss of a coin. Hence the person assessing participant eligibility did not know which treatment condition the participant would be allocated.
Query!
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
After inclusion of eligible participants in trial, allocation to condition was done by the investigator by coin toss.
