CRF
A process evaluation to describe fidelity in intervention delivery and also uptake was conducted using data captured within case report forms (CRF). This included describing the proportion with LA and CO measurements recorded, proportion setting a quit date, length of time between baseline and quit date, number of behavioural support sessions attended, and use of pharmacotherapy at any time point during the study. We also captured audio recordings of a sample of participant baseline visits in order to assess fidelity in intervention delivery.
