5 Recommendations for research
PHIAC considered that research funding agencies should ensure that a programme is established to identify the most effective and cost-effective brief interventions for smoking cessation.
The Committee recommended that the following five key research questions be addressed.
Which brief interventions are most effective (and cost effective) for pregnant women and for people in lower socioeconomic and vulnerable groups – and why?
What are the key characteristics of an effective brief intervention for smoking cessation?
How effective (and cost effective) – in absolute and relative terms – are brief interventions delivered by different professionals in a variety of settings?
Has the impact of brief interventions changed as a result of increased investment in tobacco control activities, including development of the NHS smoking cessation services?
Does an individual's previous 'quitting history' affect the success of any subsequent brief intervention?
Ideally all studies should include short (4 week), medium (3 month) and long term (1 year) follow-up and biochemical validation.
